Agglomeration and Dispersion Effects of Industry Geographic Concentration on Regional Coordinated Development

Spatial agglomeration of economic activities and the resulting differences in regional economic growth is an economic reality of our country.In order to find the form mechanism and micro effects of industrial spatial distribution on regional disparities and economic growth,this paper,based on this new economic geography and endogenous economic growth theory,builds a local spillover model and spatial econometric model to analyze demand ralated effects,spillover effects and crowding effects of industry geographic concentration on regional coordinated development.The results show that demand ralated effects and spillover effects are gathered force,and crowding effects is dispersion force to maintain balance symmetric.At the same time,spillover effects can also be a force for economic dispersion.Comparison of gathered power and dispersion power phasically changes,and gathered power of the initial stage is greater than the dispersion power,so there is inverted U relationship among industry agglomeration,economic development and regional gap.Spillover effects of human capital are conducive to narrow the regional gap.
