The Impact Of Population Agglomeration On Regional Technological Innovation Capability

Since the reform and opening up,China's economy has shifted from a high-speed development stage to a new normal.At this stage,to cultivate new economic growth points,it is necessary to improve regional technological innovation capabilities.On the other hand,the level of urbanization in China continues to increase and the urban population continues to expand.As the main body of innovation,the combination of the population gathered in the process of urbanization and the technological innovation capability of the region is of great significance to improve regional innovation capabilities.In recent years,population and regional innovation issues have attracted widespread attention.The academic community has also conducted a lot of research on the relationship between agglomeration economy and innovation.The research results show that spatial agglomeration has a significant positive effect on regional technological innovation.In theory,driven by population factors,the higher the degree of agglomeration,the stronger the technological innovation capability of the region.However,in reality,the problem of uneven development of regional technological innovation is outstanding,and it does not match the level of population agglomeration.This paper attempts to separate the talents representing the high-tech labor force from the population from the perspective of population heterogeneity,and further integrates the four major regions into the scope of research,hoping to have a new exploration of the relationship between population and technological innovation.This paper mainly studies the impact of population agglomeration on regional technological innovation.Firstly,relevant concepts and theoretical background are sorted out,and the relevant studies on population agglomeration and technological innovation by domestic and foreign scholars are reviewed.Secondly,analyzing the development status of regional technological innovation in China from two aspects of input and output.Thirdly,it analyzes the influence mechanism of population agglomeration on technological innovation from the perspectives of agglomeration effect and congestion effect,and the hypothesis that talent agglomeration has significant promoting effect on regional technological innovation and that population agglomeration has non-linear relationship with regional technological innovation is put forward.Finally,a linear regression model is established to test the first hypothesis;The second panel hypothesis is tested by using the sys-GMM method to establish a nonlinear panel data regression model.Considering the heterogeneity of the four regions,this paper made an empirical analysis of the four regions.and further introduced the panel threshold model to strengthen the regression results.The research results show that:(1)talent agglomeration has a significant positive effect on regional technological innovation ability,and for every 1 percentage point increase in talent agglomeration,regional technological innovation ability increases by 0.028 percentage points.(2)There is an inverted u-shaped relationship between population agglomeration and regional technological innovation,but the regression results of the four major regions show differences:The eastern and northeastern regions show an inverted u-shaped relationship,while the central and western regions show a positive u-shaped relationship,and the effect of the effect shows the situation of the east>northeast>middle>west.(3)Using panel threshold model for empirical research,it is found that there is a double threshold between population agglomeration and regional technological innovation ability,that is,the small scale of agglomeration area led to the insufficient "agglomeration effect",while the large scale of agglomeration area led to the excessive "crowding effect",which further affected regional technological innovation ability.
