An Empirical Study on Spatial Agglomeration and China's Provincial Economic Growth:1991~2010
利用1991-2010年中国省级面板数据，采用两阶段最小二乘法克服内生性，发现空间集聚显著促进省级经济增长，且该效应随运输成本降低而减弱，对沿海和内陆地区影响不同。
Based on the China's provincial panel data from 1991 to 2010,this paper uses the two- stage least squares method to estimate the impact of spatial agglomeration on provincial economic growth,which effectively overcomes the possible endogeneity issues in our regression and rectifies the downward bias problem in the past research.We find that the impact of spatial agglomeration on provincial economic growth spatial agglomeration is positive and statistically significant,and we also find that this impact can be weakened as the transportation cost reduces.Besides,the result survives from various robustness checks.In addition,the sub- regional regression shows that the effect of spatial agglomeration depends on the dimension of the geographic location(coastal or inland areas).
