The provincial model's population for China was rolled up in IFs and compared to other population forecasts for China, as shown below. It is clear that the population forecast from the sum of the provinces (IFs_WB) is in line with other forecasting models. Nanjing University's forecasting model is the most off from the rest of the forecasts, where population growth is forecast to continue to rise. | The provincial model's population for China was rolled up in IFs and compared to other population forecasts for China, as shown below.

It was difficult to find provincial forecasts on China, but there was one paper that was found in Mandarin that had provincial population forecasts for China's provinces. The paper from Nanjing University compared its forecasts to several other population forecasting models of China and this data was used to compare the IFs provincial model to. As was previously stated, Nanjing University's model has a steeper slope and forecasts population to continue to rise at the same rate, which all other forecasting models do not. This suggests that it might not be as good of a model as the others, but it gives some information about our forecasts. | It was difficult to find provincial forecasts on China, but there was one paper that was found in Mandarin that had provincial population forecasts for China's provinces.

== Anhui == | === Migration === | ||
Migration rates for China's provinces are not publicly available, nor are there forecasts of China's migration rates. This means that the model is without migration, which is problematic because intranational migration is a salient issue that is shaping provincial populations. For instance, Beijing's population pyramid shows a population that has been shaped by migration because of the large young working population relative to the number of children. There are also visible jumps up and down in population in provinces that are clearly attributed to migration. | |||
[[File:ChinaBeijingPopPyramid v728.png|900px|ChinaBeijingPopPyramid v728.png]] | |||
To address the lack of migration data and appropriately capture the impact of migration within China, migration rates are estimated. First, provinces with net inward migration and net outward migration are identified by looking at the population data from 2000 through 2014. This span of years is when internal migration in China increased significantly and it is where migration rates are most visible in graphs of population. Below is a table that summarizes the migration trends that are visible in the provincial population and the following section shows graphs of population with history and forecasts for each province in China for comparison. | |||

==== Estimation Methods ==== | |||
Below is a province-by-province comparison of migration and population. First is population by province in the base case, without migration that is compared to Nanjing University's provincial population forecasts. | |||
Second is the first method of estimating the flow of migrants, this is the net number of new migrants in millions. To estimate the new migrants; historical crude birth rates, crude death rates, and population were used to calculate total births and deaths in millions starting in 1990. Births and deaths were then added to the previous year's population to generate an estimate of population without migration. For instance, population in 1990 for Anhui province is 54.7 million and births and deaths total to a net 0.84 million people in 1991. Then the population without migration in 1991 is estimated to be 55.54 million (54.7+0.84=55.54). These migration estimates are compared to a 5-year moving average of migrant flows from a paper that estimated subnational migration in China from 1990 through 2005. | |||
The third graph is a comparison of a second method of net migrant estimation with the first method and the paper's migrant flows. The second estimation method is a five-year moving average of the first method's net migrants. | |||
===== Migration Scenario 1 ===== | |||
A migration scenario was generated using the second method of net migrants estimation and population to calculate a net migration rate. The calculated migration rate for 2014 was used for 2014 in the scenario using the ''migrater'' parameter. Then all provinces were interpolated to 0 at the end of the time horizon in 2100. | |||
====== China's Population After Migration Scenario 1 ====== | |||
After the migration scenario the total population in China is slightly higher than the 186 model and the base case. | |||
[[File:ChinaPopSCE.png|900px|ChinaPopSCE.png]] | |||
===== Migration Scenario 2 ===== | |||
Building upon the first migration scenario, a second scenario was created. The second scenario includes India's final scenario migration data and China's in the same scenario run. Additionally, some province's migration rates were adjusted to improve model behavior because the inclusion of India's migration rates in the scenario run made the net inward migration in several Chinese provinces greater than it was in the original run. | |||
====== China's Population After Migration Scenario 2 ====== | |||
The second scenario forecasts all of China's population to be greater than the first scenario, but after careful calibration it is still close. The first scenario forecasts population to be about 18 million greater than the 186 model forecasts in 2100. Whereas, the second scenario forecasts population to be about 36 million greater than the 186 model in 2100. | |||
[[File:ChinaPopSCE2.png|900px|ChinaPopSCE2.png]] | |||
The migration scenario also improved age-sex forecasts for provinces, such as Beijing, that have a substantial migrant worker population. Below is a comparison of the base case forecast of Beijing's population pyramid and the second scenario's forecast in 2060. It is clear that there will be a significant elderly population in Beijing by 2060, but the burden is more realistic in the scenario because of the influx of migrants. | |||

=== Anhui === | |||
==== Population ==== | |||
Anhui's population takes a significant dip around 2008, which shows net-outward migration. | |||

==== Migration Scenario 1 Results ==== | |||
===== Population After Migration Scenario 1 ===== | |||
Beijing's population is significantly higher after the senario and we may want to decrease the inward migration slightly. | |||
[[File:BeijingPopSCE.png|900px|BeijingPopSCE.png]] | |||
===== Migration Rate After Migration Scenario 1 ===== | |||
The model pushes migration down more rapidly than what is in the scenario, which is probably a good thing being the initial migration rate for Beijing is so high. | |||
[[File:BeijingMigRateSCE.png|900px|BeijingMigRateSCE.png]] | |||
==== Migration Scenario 2 Results ==== | |||
Beijing's migration rate has been lowered in the second scenario from 3.56 in 2014 to 1.26 in 2014. | |||

=== Chongqing === | |||
==== Population ==== | |||
The World Bank data was interpolated in the model which fills the population back to 1960 smoothly. In reality the municipality did not bifurcate from Sichuan until 1997 and its borders were redefined several times between 1997 and 2008. Thus Nanjing University's historical data's strange behavior makes sense, but the forecasts look too high. | |||

== China's Crude Birth Rates == | |||
CBRs in the provincial model are quite close to the 186 model. There is a greater difference in the historical data than in the forecasts, but overall the two models are quite close. | |||
[[File:ChinaCBR v728.png|900px|ChinaCBR v728.png]] | |||
== China's Crude Death Rates == | |||
Like CBRs, CDRs are quite close in the two models. There is a greater difference towards the end of the forecasts after 2065. | |||
[[File:ChinaCDR v728.png|900px|ChinaCDR v728.png]] | |||
== China's Migration Rates == | |||
Migration rates that have been included in the model are historical and were found in a paper<ref>Kam Wing Chan, Forthcoming in; The Encyclopedia of Global Migration, edited by Immanuel Ness (Blackwell Publishing, 2017).</ref> that estimates sub-national migration in China. Chinese intranational migration has proven to be a difficult measure because there is a significant amount of illegal migration from rural areas to urban areas. | |||
There is only historical data available. Therefore the migration rates do not impact the forecasts because the model does not endogenously calculate migration forecasts. | |||
The two models appear to be different historically, but it should be noted that both models' migration rates are almost zero for all years. The difference between them is small in total, but the magnitude appears to be large. | |||
[[File:ChinaMigRate v728.png|900px|ChinaMigRate v728.png]] | |||
== China's Total Fertility Rates == | |||
There is only a single year of historical data for provincial TFR in China and unfortunately the data is from 2000, making this series outdated. For all provinces except Beijing, the 2000 historical data point is the same as the 2014 data point when the model initializes. Due to the outdated data being used for model initialization the provincial model's forecasts of TFR are slightly lower than the 186 model initially. | |||
[[File:ChinaTFR v728.png|900px|ChinaTFR v728.png]] | |||
It is also important to note that provinces such as Beijing are outliers compared to the rest of the world due to the impact of the ''One Child Policy'' in China's urban areas. Unlike the rest of the world where TFR is forecast to decline to 1.9 and then remain at that level throughout the end of the time horizon, most provinces are forecast to have TFR increase to 1.9 and then remain at that rate through the end of the time horizon. Only Guizhou, Tibet, and Yunnan provinces have TFR above 1.9 historically that are forecast to decline to 1.9. | |||
There are no known forecasts to compare the provincial forecasts for TFR with. The model's behavior looks good and without an available data source to update the historical data there is nothing that can be reasonably done to get the provincial model to match the 186 version. | |||
== China's Life Expectancy == | |||
Life expectancy in China's provincial model is in line with the 186 model historically and through the end of the time horizon in the forecasts. Male life expectancy is slightly lower in the provincial model than in the 186 model, but female life expectancy and total life expectancy are nearly identical in the two models. | |||

= Economy = | |||
China's provincial model GDP appears to be too high in the forecasts relative to the 186 model. This appears to be driven by productivity in the provincial model, specifically in Physical Capital, as documented below. There is positive contributions to growth from Physical Capital in the provincial model when it is negative in the 186 model. What is driving this divergence is unclear because there is so little provincial data in the Infrastructure module. There is only one series in China's Infrastructure module, which is ''ICTTelephoneLinesPer1000''. This series appears to be identical to the 186 model and does not appear to be the cause of this increased productivity in the provincial model. Value added appears to be inline with the 186 model as does government spending and both are normalized to the 186 model using ''ApplyMultAll''. [[File:2017-06-29.png|900px|2017-06-29.png]] | |||
The following sections document the economy module as it appears after the final migration scenario. The documentation also breaks down what may be driving the observed divergence in forecast GDP growth between the provincial model and the 186 model. | |||
== China's GDP == | |||
Provincial GDP is significantly greater than the 186-model's GDP and after the migration scenario, this difference is greater in the latter years of forecasts. The second migration scenario forecasts lower GDP than in the first, but it is still significantly greater than the 186 model. | |||
[[File:ChinaGDPSCE2.png|900px|ChinaGDPSCE2.png]] | |||
=== Anhui's GDP === | |||
Anhui's GDP is lower in the two scenarios because the population is forecast to decline due to outward migration. | |||
[[File:AnhuiGDPSCE2.png|900px|AnhuiGDPSCE2.png]] | |||
=== Beijing's GDP === | |||
Beijing's GDP varies greatly between the three versions. This is driven by the composition of the population in Beijing. Beijing's population in the base case is forecast to age rapidly due to the lack of migration that makes up much of Beijings workforce. This working-aged population is largest in the first scenario, and the second scenario is about in between the base case and the first scenario.

=== Shandong's GDP === | |||
[[File:ShandongGDPSCE2.png|900px|ShandongGDPSCE2.png]] | |||
=== Shanghai's GDP === | |||
Like Beijing the three GDP forecasts are dramatically different due to variances in the working-aged population. The base case forecasts a rapidly aging population that is a drag on the economy because there is a shrinking working-aged population. The first scenario increases GDP by a significant margin due to a huge migrant population that improves the stock of labor. The second scenario shoots in the middle, producing a forecast of growing GDP by a decreasing rate due to the aging population. | |||
[[File:ShanghaiGDPSCE2.png|900px|ShanghaiGDPSCE2.png]] | |||
=== Shanxi's GDP === | |||
[[File:ShanxiGDPSCE2.png|900px|ShanxiGDPSCE2.png]] | |||
=== Sichuan's GDP === | |||
[[File:SichuanGDPSCE2.png|900px|SichuanGDPSCE2.png]] | |||
=== Tianjin's GDP === | |||
Tianjin's population is aging, much like what was documented in Shanghai and Beijing. The inward migration is where much of the labor force comes from and therefore, the inward migration of the scenarios increases GDP forecasts substantially. The second scenario is a more cautious forecast and shows GDP growth at a decreasing rate due to the aging population that is supported by inward migration. | |||

== China's GDP per Capita == | |||
China's GDP per capita in the provincial model and in the scenario are significantly greater than the GDP per capita in the 186 version of IFs. This is expected because the total population is close in the models but, the GDP is greater in the provincial model. | |||

== Value Added == | |||
Value added in all sectors are relatively close in both models, but it is slightly lower in the provincial model overall. The disparity between the two model's GDP does not appear to be driven by value added. | |||
=== Agriculture Value Added as a Percentage of GDP === | |||
The provincial model has higher value added in agriculture historically, but is forecast to have slightly lower value added in the future. | |||
[[File:ChinaAgVadd v728.png|900px|ChinaAgVadd v728.png]] | |||
=== Energy Value Added as a Percentage of GDP === | |||
Value added in energy is forecast to be lower in the provincial model until around 2075 when the two models are forecast to be about the same. | |||
[[File:ChinaEnVadd v728.png|900px|ChinaEnVadd v728.png]] | |||
=== Materials Value Added as a Percentage of GDP === | |||
Value added in materials is forecast to be lower in the provincial model by about a percentage point for all years. | |||
[[File:ChinaMatVadd v728.png|900px|ChinaMatVadd v728.png]] | |||
=== Manufacturing Value Added as a Percentage of GDP === | |||
Manufacturing value added is relatively close in both models, with the provincial model being slightly greater. | |||
[[File:ChinaManufacturingVAdd v728.png|900px|ChinaManufacturingVAdd v728.png]] | |||
=== Services Value Added as a Percentage of GDP === | |||
The two models are close historically and are forecast to be identical after 2035. | |||
[[File:ChinaSerVadd v728.png|900px|ChinaSerVadd v728.png]] | |||
=== ICT Value Added as a Percentage of GDP === | |||
ICT forecasts are nearly identical. | |||
[[File:ChinaICTVadd v728.png|900px|ChinaICTVadd v728.png]] | |||
== Government Consumption == | |||
Government spending is a key driver in the economy module and it directly impacts multifactor productivity. The graphs of GDS suggest that the 186 and provincial model have the same starting point but have different growth rates in the forecasts. | |||
=== Military === | |||
Military spending is greater in the provincial model, why this is occurring is not clear because there is not any historical data for this series. | |||
[[File:ChinaGDSMil v728.png|900px|ChinaGDSMil v728.png]] | |||
=== Education === | |||
The provincial model is initially greater than the 186-model and after 2055 the provincial model is lower. There is historical data in the provincial model for this series. | |||
[[File:ChinaGDSEd v728.png|900px|ChinaGDSEd v728.png]] | |||
=== Health === | |||
The two models are initially close together, but over time the provincial model becomes greater than the 186-model by an increasing margin. There is historical data for this series. | |||
[[File:ChinaGDSHealth v728.png|900px|ChinaGDSHealth v728.png]] | |||
=== Research and Development === | |||
There is more investment in research and development in the provincial model, but the total amount is very small in both models. There is historical provincial data for this series. | |||
[[File:ChinaGDSR&D v728.png|900px|ChinaGDSR&D v728.png]] | |||
=== Infrastructure === | |||
Infrastructure spending is close in the two models. There is not any historical provincial data for this series. | |||
[[File:ChinaGDSInfra v728.png|900px|ChinaGDSInfra v728.png]] | |||
=== InfraOther === | |||
The provincial model has more InfraOther spending than the 186-model. | |||
[[File:ChinaGDSInfraOther v728.png|900px|ChinaGDSInfraOther v728.png]] | |||
=== Other === | |||
Other spending is significantly greater in the provincial model. | |||
[[File:ChinaGDSOth v728.png|900px|ChinaGDSOth v728.png]] | |||
== MultiFactor Productivity == | |||
Multifactor productivity is significantly larger in the provincial model than in the 186-model, and therefore it is the likely culprit for what is driving the disparity between the two model's GDP forecasts. | |||
=== Agriculture MFP === | |||
The provincial model is slightly lower than the 186-model until around 2040. After 2040, the provincial model is greater than the 186-model by an increasing margin. | |||
[[File:ChinaMFPAg v728.png|900px|ChinaMFPAg v728.png]] | |||
=== Energy MFP === | |||
Multifactor productivity in energy is much greater in the provincial model. | |||
[[File:ChinaMFPEn v728.png|900px|ChinaMFPEn v728.png]] | |||
=== Materials MFP === | |||
Multifactor productivity in materials is much greater in the provincial model than in the 186-model. | |||
[[File:ChinaMFPMat v728.png|900px|ChinaMFPMat v728.png]] | |||
=== Manufacturing MFP === | |||
The provincial model has much greater multifactor productivity in manufacturing than the 186-model. | |||
[[File:ChinaMFPManufactures v728.png|900px|ChinaMFPManufactures v728.png]] | |||
=== Services MFP === | |||
Multifactor productivity is much greater in the provincial model. | |||
[[File:ChinaMFPser v728.png|900px|ChinaMFPser v728.png]] | |||
=== ICT MFP === | |||
Multifactor productivity is significantly greater in the provincial model. | |||
[[File:ChinaMFPICT v728.png|900px|ChinaMFPICT v728.png]] | |||
== Growth Acounting == | |||
=== Capital === | |||
There is significantly more growth in capital in the materials sector in the provincial model, than there is in the 186 model. | |||

[[File:ChGACapital186.png|900px|ChGACapital186.png]] | |||
=== Labor === | |||
The two models are quite close in the area of labor, but the provincial model is positive in the beginning, whereas the 186 model is not. | |||
==== Labor in the Provincial Model ==== | |||

==== Labor in the 186 Model ==== | |||
[[File:ChGALabor186.png|900px|ChGALabor186.png]] | |||
=== MultiFactor Productivity === | |||
MFP is greater in 2019 in the 186 model, but it is greater in all other years in the provincial model. Manufacturing is the key exception to this because it is greater in all years in the 186 model. | |||
==== MultiFactor Productivity in the Provincial Model ==== | |||

==== MultiFactor Productivity in the 186 Model ==== | |||
[[File:ChGAMFP186.png|900px|ChGAMFP186.png]] | |||
=== Technology Base MultiFactor Productivity === | |||
ICT is about the same in the two models, but it decreases at a slower rate in the 186 model. The remaining sectors are greater in the provincial model and decline over time, whereas the 186 model forecasts all other sectors (not ICT) to be about the same in all years. | |||
==== Technology Base MFP in the Provincial Model ==== | |||
[[File:ChGATechMFPProv.png|900px|ChGATechMFPProv.png]] | |||
==== Technology Base MFP in the 186 Model ==== | |||
[[File:ChGATechMFP186.png|900px|ChGATechMFP186.png]] | |||
=== Knowledge Base MultiFactor Productivity === | |||
There are differences between sectors in the provincial model, whereas the 186 model shows them all the be the same. The actual growth contributions are similar, but clearly there is a difference. The provincial model is greater in some of the earlier years where there is the large jump in provincial GDP. | |||

[[File:ChGAKnowledgeMFP.png|900px|ChGAKnowledgeMFP.png]] | |||
=== Human Capital MultiFactor Productivity === | |||
Like what was documented in the area of Knowledge Capital, there is a difference among the sectors contribution to growth in the provincial. The 186 model has the same amount of growth contribution for all sectors in all years. On average the two models appear to be about the same. | |||
==== Human Capital MFP in the Provincial Model ==== | |||

[[File:CHGAHumanCapitalMFP186.png|900px|CHGAHumanCapitalMFP186.png]] | |||
=== Social Capital MultiFactor Productivity === | |||
Social Capital MFP is greater in the provincial model from the first year of forecasts through 2044, after that the 186 model is greater. Once again there is a difference between sectors in the provincial model, but not in the 186 model. | |||
==== Social Capital MFP in the Provincial Model ==== | |||

[[File:ChGASocialCapitalMFP186.png|900px|ChGASocialCapitalMFP186.png]] | |||
=== Physical Capital MultiFactor Productivity === | |||
This area appears to be the area of greatest difference between the two models. Physical capital contributes to growth in the provincial model, whereas, in the 186 model it has a negative contribution. There is also a difference among sectors in the provincial model, that does not occur in the 186 model. | |||
==== Physical Capital MFP in the Provincial Model ==== | |||

== Foreign Direct Investment == | |||
Provincial FDI historically is quite close to the 186 model from 1973 through 1995. After 1995, there is a dramatic divergence. The provincial forecast initializes at 0 in 2014. This appears to be a major contributor to throwing off GDP in China. | |||

Latest revision as of 22:04, 3 July 2017
Overview
China's sub-regional model has a total of 63 preprocessor series. Although there are 652 preprocessor series in the IFs model, there are many that are not applicable to sub-regional models or do not significantly impact forecasts; only 355 preprocessor series are sought for sub-regionalization. Thus China's sub-regional model has nearly 18% coverage at this point. There are a 29 preprocessor series that have been identified that could be pulled into the model. If this data was to be pulled the the total coverage of the model would increase to nearly 26%.
Below is a table that shows the module coverage for the China sub-regional model. Population has the most coverage, but this is also the fewest number of preprocessor series. The economy module has the second highest coverage, which is good. Population and Economy have the greatest impact on the model's overall behavior and coverage in these modules is important. Health and education are areas of weakness for the China sub-regional model. In part the weakness is driven by the large number of series in those modules. There is more education data available that could be brought into the model, but some of the data requires historical age-sex cohorts to calculate rates with the data. Health has low coverage because there is not a lot of health data that is available for free and in English. It appears that much of China's health data is proprietary and not publicly available, but there may be alternative sources available if a researcher searched in Mandarin.
IFs Module | Preprocessor Series Pulled | Total Preprocessor Series | Module Coverage |
---|---|---|---|
Population | 7 | 8 | 87.5% |
Economy | 24 | 55 | 43.6% |
Health | 5 | 57 | 8.8% |
Education | 8 | 91 | 8.8% |
Agriculture | 11 | 36 | 30.6% |
Energy | 7 | 66 | 10.6% |
Infrastructure | 1 | 21 | 4.8% |
Environment | 0 | 9 | 0.0% |

Total | 63 | 355 | 17.7% |
Potential Series | 92 | 355 | 25.9% |
Population
China's Population
The provincial model's population for China was rolled up in IFs and compared to other population forecasts for China, as shown below. It is clear that the population forecast from the sum of the provinces (IFs_WB) is in line with other forecasting models. Nanjing University's forecasting model is the most off from the rest of the forecasts, where population growth is forecast to continue to rise.
It was difficult to find provincial forecasts on China, but there was one paper that was found in Mandarin that had provincial population forecasts for China's provinces. The paper from Nanjing University compared its forecasts to several other population forecasting models of China and this data was used to compare the IFs provincial model to. As was previously stated, Nanjing University's model has a steeper slope and forecasts population to continue to rise at the same rate, which all other forecasting models do not. This suggests that it might not be as good of a model as the others, but it gives some information about our forecasts.
Migration
Migration rates for China's provinces are not publicly available, nor are there forecasts of China's migration rates. This means that the model is without migration, which is problematic because intranational migration is a salient issue that is shaping provincial populations. For instance, Beijing's population pyramid shows a population that has been shaped by migration because of the large young working population relative to the number of children. There are also visible jumps up and down in population in provinces that are clearly attributed to migration.
To address the lack of migration data and appropriately capture the impact of migration within China, migration rates are estimated. First, provinces with net inward migration and net outward migration are identified by looking at the population data from 2000 through 2014. This span of years is when internal migration in China increased significantly and it is where migration rates are most visible in graphs of population. Below is a table that summarizes the migration trends that are visible in the provincial population and the following section shows graphs of population with history and forecasts for each province in China for comparison.
Net Inward Migration | Net Outward Migration | Flat Migration |
Beijing | Anhui | Chongqing |
Guangdong | Gansu | Fujian |
Hebei | Guizhou | Hunan |
Hubei | Guangxi | Jiangsu |
Jiangxi | Heilongjiang | Liaoning |
Shanghai | Henan | Nei Mongol |
Tianjin | Jilin | Ningxia |
Xinjiang | Shaanxi | Qinghai |
Hainan | Sichuan | Shandong |
Yunnan | Shanxi | |
Tibet | ||
Zhejiang |
Estimation Methods
Below is a province-by-province comparison of migration and population. First is population by province in the base case, without migration that is compared to Nanjing University's provincial population forecasts.
Second is the first method of estimating the flow of migrants, this is the net number of new migrants in millions. To estimate the new migrants; historical crude birth rates, crude death rates, and population were used to calculate total births and deaths in millions starting in 1990. Births and deaths were then added to the previous year's population to generate an estimate of population without migration. For instance, population in 1990 for Anhui province is 54.7 million and births and deaths total to a net 0.84 million people in 1991. Then the population without migration in 1991 is estimated to be 55.54 million (54.7+0.84=55.54). These migration estimates are compared to a 5-year moving average of migrant flows from a paper that estimated subnational migration in China from 1990 through 2005.
The third graph is a comparison of a second method of net migrant estimation with the first method and the paper's migrant flows. The second estimation method is a five-year moving average of the first method's net migrants.
Migration Scenario 1
A migration scenario was generated using the second method of net migrants estimation and population to calculate a net migration rate. The calculated migration rate for 2014 was used for 2014 in the scenario using the migrater parameter. Then all provinces were interpolated to 0 at the end of the time horizon in 2100.
China's Population After Migration Scenario 1
After the migration scenario the total population in China is slightly higher than the 186 model and the base case.
Migration Scenario 2
Building upon the first migration scenario, a second scenario was created. The second scenario includes India's final scenario migration data and China's in the same scenario run. Additionally, some province's migration rates were adjusted to improve model behavior because the inclusion of India's migration rates in the scenario run made the net inward migration in several Chinese provinces greater than it was in the original run.
China's Population After Migration Scenario 2
The second scenario forecasts all of China's population to be greater than the first scenario, but after careful calibration it is still close. The first scenario forecasts population to be about 18 million greater than the 186 model forecasts in 2100. Whereas, the second scenario forecasts population to be about 36 million greater than the 186 model in 2100.
The migration scenario also improved age-sex forecasts for provinces, such as Beijing, that have a substantial migrant worker population. Below is a comparison of the base case forecast of Beijing's population pyramid and the second scenario's forecast in 2060. It is clear that there will be a significant elderly population in Beijing by 2060, but the burden is more realistic in the scenario because of the influx of migrants.

Chongqing
Population
The World Bank data was interpolated in the model which fills the population back to 1960 smoothly. In reality the municipality did not bifurcate from Sichuan until 1997 and its borders were redefined several times between 1997 and 2008. Thus Nanjing University's historical data's strange behavior makes sense, but the forecasts look too high.

China's Crude Birth Rates
CBRs in the provincial model are quite close to the 186 model. There is a greater difference in the historical data than in the forecasts, but overall the two models are quite close.
China's Crude Death Rates
Like CBRs, CDRs are quite close in the two models. There is a greater difference towards the end of the forecasts after 2065.
China's Migration Rates
Migration rates that have been included in the model are historical and were found in a paper[1] that estimates sub-national migration in China. Chinese intranational migration has proven to be a difficult measure because there is a significant amount of illegal migration from rural areas to urban areas.
There is only historical data available. Therefore the migration rates do not impact the forecasts because the model does not endogenously calculate migration forecasts.
The two models appear to be different historically, but it should be noted that both models' migration rates are almost zero for all years. The difference between them is small in total, but the magnitude appears to be large.
China's Total Fertility Rates
There is only a single year of historical data for provincial TFR in China and unfortunately the data is from 2000, making this series outdated. For all provinces except Beijing, the 2000 historical data point is the same as the 2014 data point when the model initializes. Due to the outdated data being used for model initialization the provincial model's forecasts of TFR are slightly lower than the 186 model initially.
It is also important to note that provinces such as Beijing are outliers compared to the rest of the world due to the impact of the One Child Policy in China's urban areas. Unlike the rest of the world where TFR is forecast to decline to 1.9 and then remain at that level throughout the end of the time horizon, most provinces are forecast to have TFR increase to 1.9 and then remain at that rate through the end of the time horizon. Only Guizhou, Tibet, and Yunnan provinces have TFR above 1.9 historically that are forecast to decline to 1.9.
There are no known forecasts to compare the provincial forecasts for TFR with. The model's behavior looks good and without an available data source to update the historical data there is nothing that can be reasonably done to get the provincial model to match the 186 version.
China's Life Expectancy
Life expectancy in China's provincial model is in line with the 186 model historically and through the end of the time horizon in the forecasts. Male life expectancy is slightly lower in the provincial model than in the 186 model, but female life expectancy and total life expectancy are nearly identical in the two models.
Total Life Expectancy
Life Expectancy Female
Life Expectancy Male
Economy
China's provincial model GDP appears to be too high in the forecasts relative to the 186 model. This appears to be driven by productivity in the provincial model, specifically in Physical Capital, as documented below. There is positive contributions to growth from Physical Capital in the provincial model when it is negative in the 186 model. What is driving this divergence is unclear because there is so little provincial data in the Infrastructure module. There is only one series in China's Infrastructure module, which is ICTTelephoneLinesPer1000. This series appears to be identical to the 186 model and does not appear to be the cause of this increased productivity in the provincial model. Value added appears to be inline with the 186 model as does government spending and both are normalized to the 186 model using ApplyMultAll.
The following sections document the economy module as it appears after the final migration scenario. The documentation also breaks down what may be driving the observed divergence in forecast GDP growth between the provincial model and the 186 model.
China's GDP
Provincial GDP is significantly greater than the 186-model's GDP and after the migration scenario, this difference is greater in the latter years of forecasts. The second migration scenario forecasts lower GDP than in the first, but it is still significantly greater than the 186 model.
Anhui's GDP
Anhui's GDP is lower in the two scenarios because the population is forecast to decline due to outward migration.
Beijing's GDP
Beijing's GDP varies greatly between the three versions. This is driven by the composition of the population in Beijing. Beijing's population in the base case is forecast to age rapidly due to the lack of migration that makes up much of Beijings workforce. This working-aged population is largest in the first scenario, and the second scenario is about in between the base case and the first scenario.

Jiangxi's GDP
Jilin's GDP
Liaoning's GDP
Nei Mongol's GDP
Ningxia's GDP
Qinghai's GDP
Shaanxi's GDP
Shandong's GDP
Shanghai's GDP
Like Beijing the three GDP forecasts are dramatically different due to variances in the working-aged population. The base case forecasts a rapidly aging population that is a drag on the economy because there is a shrinking working-aged population. The first scenario increases GDP by a significant margin due to a huge migrant population that improves the stock of labor. The second scenario shoots in the middle, producing a forecast of growing GDP by a decreasing rate due to the aging population.
Shanxi's GDP
Sichuan's GDP
Tianjin's GDP
Tianjin's population is aging, much like what was documented in Shanghai and Beijing. The inward migration is where much of the labor force comes from and therefore, the inward migration of the scenarios increases GDP forecasts substantially. The second scenario is a more cautious forecast and shows GDP growth at a decreasing rate due to the aging population that is supported by inward migration.
Tibet's GDP
Xinjiang's GDP
Yunnan's GDP
Zhejiang's GDP
China's GDP per Capita
China's GDP per capita in the provincial model and in the scenario are significantly greater than the GDP per capita in the 186 version of IFs. This is expected because the total population is close in the models but, the GDP is greater in the provincial model.

Value Added
Value added in all sectors are relatively close in both models, but it is slightly lower in the provincial model overall. The disparity between the two model's GDP does not appear to be driven by value added.
Agriculture Value Added as a Percentage of GDP
The provincial model has higher value added in agriculture historically, but is forecast to have slightly lower value added in the future.
Energy Value Added as a Percentage of GDP
Value added in energy is forecast to be lower in the provincial model until around 2075 when the two models are forecast to be about the same.
Materials Value Added as a Percentage of GDP
Value added in materials is forecast to be lower in the provincial model by about a percentage point for all years.
Manufacturing Value Added as a Percentage of GDP
Manufacturing value added is relatively close in both models, with the provincial model being slightly greater.
Services Value Added as a Percentage of GDP
The two models are close historically and are forecast to be identical after 2035.
ICT Value Added as a Percentage of GDP
ICT forecasts are nearly identical.
Government Consumption
Government spending is a key driver in the economy module and it directly impacts multifactor productivity. The graphs of GDS suggest that the 186 and provincial model have the same starting point but have different growth rates in the forecasts.
Military
Military spending is greater in the provincial model, why this is occurring is not clear because there is not any historical data for this series.
Education
The provincial model is initially greater than the 186-model and after 2055 the provincial model is lower. There is historical data in the provincial model for this series.
Health
The two models are initially close together, but over time the provincial model becomes greater than the 186-model by an increasing margin. There is historical data for this series.
Research and Development
There is more investment in research and development in the provincial model, but the total amount is very small in both models. There is historical provincial data for this series.
Infrastructure
Infrastructure spending is close in the two models. There is not any historical provincial data for this series.
InfraOther
The provincial model has more InfraOther spending than the 186-model.
Other
Other spending is significantly greater in the provincial model.
MultiFactor Productivity
Multifactor productivity is significantly larger in the provincial model than in the 186-model, and therefore it is the likely culprit for what is driving the disparity between the two model's GDP forecasts.
Agriculture MFP
The provincial model is slightly lower than the 186-model until around 2040. After 2040, the provincial model is greater than the 186-model by an increasing margin.
Energy MFP
Multifactor productivity in energy is much greater in the provincial model.
Materials MFP
Multifactor productivity in materials is much greater in the provincial model than in the 186-model.

MultiFactor Productivity in the 186 Model
Technology Base MultiFactor Productivity
ICT is about the same in the two models, but it decreases at a slower rate in the 186 model. The remaining sectors are greater in the provincial model and decline over time, whereas the 186 model forecasts all other sectors (not ICT) to be about the same in all years.
Technology Base MFP in the Provincial Model
Technology Base MFP in the 186 Model
Knowledge Base MultiFactor Productivity
There are differences between sectors in the provincial model, whereas the 186 model shows them all the be the same. The actual growth contributions are similar, but clearly there is a difference. The provincial model is greater in some of the earlier years where there is the large jump in provincial GDP.
Knowledge Base MFP in the Provincial Model
Knowledge Base MFP in the 186 Model
Human Capital MultiFactor Productivity
Like what was documented in the area of Knowledge Capital, there is a difference among the sectors contribution to growth in the provincial. The 186 model has the same amount of growth contribution for all sectors in all years. On average the two models appear to be about the same.
Human Capital MFP in the Provincial Model
Human Capital MFP in the 186 Model
Social Capital MultiFactor Productivity
Social Capital MFP is greater in the provincial model from the first year of forecasts through 2044, after that the 186 model is greater. Once again there is a difference between sectors in the provincial model, but not in the 186 model.
Social Capital MFP in the Provincial Model
Social Capital MFP in the 186 Model
Physical Capital MultiFactor Productivity
This area appears to be the area of greatest difference between the two models. Physical capital contributes to growth in the provincial model, whereas, in the 186 model it has a negative contribution. There is also a difference among sectors in the provincial model, that does not occur in the 186 model.

Foreign Direct Investment
Provincial FDI historically is quite close to the 186 model from 1973 through 1995. After 1995, there is a dramatic divergence. The provincial forecast initializes at 0 in 2014. This appears to be a major contributor to throwing off GDP in China.
