| Over the past four decades of reform and opening-up,China's economy has continued to grow at a high speed,which thanks in large part to the country's “demographic dividend”.But since 2010,the growth rate of China's labor force has slowed and the economic growth rate has begun to decline.China's "demographic dividend" is gradually disappearing,and economic growth is no longer dependent on the number of people.In recent years,China's population distribution has shown a significant agglomeration feature.In this context,this paper studies the impact of population agglomeration on economic development.Based on the data of 30 Chinese provinces(except Tibet),this paper studies the impact of population agglomeration on regional economic development in China.Firstly,introducing the concepts of population agglomeration and economic growth and reviewing relevant theories and literature.Secondly,taking the data of 30 provinces(except Tibet)from 2000 to 2017 as samples,the spatial autocorrelation analysis method is used to identify the characteristics of population spatial agglomeration and the relevant characteristics of economic development,and an unbalanced index is constructed to explore the consistency between population agglomeration and economic agglomeration.The mechanism of population agglomeration's influence on economic growth is analyzed again.Finally,the panel data of 30 provinces(except Tibet)from 2000 to 2017 were taken as samples,and the influence of population agglomeration on economic development and economic growth was empirically studied by using the fixed effect model,and the mediating effect was further analyzed to verify the mechanism.The results show that there is a high consistency between population agglomeration and economic agglomeration,and the consistency trend is increasing.Population agglomeration can significantly promote the regional economic development,improve the level of regional economic development,but with different level of economic development regions of the influence of the economic growth rate is not the same.It has a significant economic growth effect In the western region of China The mediating effect test shows that population agglomeration can promote economic growth in three aspects: human capital level,social capital and industrial structure upgrading.The reason why it has different effects on the economic growth rate of regions with different economic development levels is that different regions have different human capital,social capital and industrial structure,so the effects are different. |
