An Analysis of the Impacts of High-tech Industry Agglomeration on Labor Productivity:Based on China's Provincial Panel Data
The development characteristics of high-tech industry makes its agglomeration level higher than other industries,which has an important influence on labor productivity.This paper uses high-tech "double-digit" industry panel data of 31 provinces and cities in China from 2004 to 2014 to make linear regression and non-linear regression in the impacts of high-tech industry agglomeration on labor productivity.The results of linear regression show that diversification agglomeration of high-tech industry can improve China's labor productivity,but its significance is not robust,and specialization agglomeration will restrain the improvement of labor productivity.What's more,it is found that the impacts of diversification and specialization agglomeration on labor productivity in the eastern region and the central region is not significant,and the effect on labor productivity in the western region is consistent with that at the national level.The panel threshold tests show that the effect of high-tech industry agglomeration on labor productivity is a complex nonlinear relationship,which has some differences in different regions.Diversified agglomeration of high-tech industry is more consistent with nationwide,the eastern region and the central region,and there is no threshold effect in the western region.There is a significant negative impact on labor productivity both at the national level and in the central region before the second threshold,while the second threshold has no significant effect on labor productivity.There are negative and significant effects before and after the two thresholds in the eastern and western regions.A further investigation of the human capital as the threshold variable reveals that there is a certain spatial heterogeneity and stage characteristics in the impacts of high-tech industry agglomeration on labor productivity in China.
