| Human capital is the significant factor for the research and innovation of high-tech industry,which relies on high-tech talents to conduct scientific research,break through the difficulty and improve the innovation ability,and has gradually become the pillar industry for converting the economic development pattern,optimizing the industrial structure and enhancing the international competitiveness in China.Along with the continuous improvement of regional education level,human capital structure has become optimized by the emergence of quantities of senior talents,which providing a good development opportunity for the survival and development of regional high-tech industries.However,influenced by labor market signals,the flow of human capital between regions shows obvious characteristics of profit-seeking,which on the one hand leads to excessive brain drain in regions with lower economic development level and inhibits the improvement of regional innovation ability,and on the other hand also leads to over-concentration of talents in economically developed regions,resulting in serious talent crowding and in-roll phenomenon,which reduces the efficiency of human capital and raises the production cost of enterprises,and has a strong impact on the survival,agglomeration and development of high-tech industries finally.Therefore,it is a urgent issue for government to solve the problems about how to reasonably formulate talent policies in different regions to optimize the human capital structure,consolidate and improve the agglomeration level of local high-tech industries effectively,and promote development of economic with high quality.In view of this,the impact of the optimization of human capital structure on the agglomeration of high-tech industries and its mechanism is deeply analyzed by combing the theory of human capital and agglomeration.On the basis of the spatiality of high-tech industry agglomeration,a spatial model is constructed to verify the influence of the optimization of human capital structure on high-tech industry agglomeration by selecting provincial panel data from 2001 to 2020,and a moderating effect model and a mediating effect model are constructed to study the moderating and mediating effects of regional labor cost and regional innovation capacity respectively.Finally,regional dummy variables are constructed to further investigate the regional heterogeneity of the relationships.The results show that the connection between the optimization of human capital structure and high-tech industry agglomeration appears the effect of promoting and then inhibiting;labor cost has a significant negative moderating effect on the relationship between the two,and innovation capability plays a partial mediating role in the relationship between the two;the results of regional heterogeneity show that the relationship between the two factors has a significant inhibitory effect in the eastern region,a significant promoting effect in the central and northeastern regions,and an insignificant relationship in the western region.Based on the theoretical analysis and empirical results above,this study proposes corresponding policy recommendations from the national and regional perspectives,respectively,in terms of labor quality,labor market,and innovation capacity,in order to further optimize the human capital structure,actively guide the flow of human capital,and improve regional innovation capacity,so as to guarantee the space for the survival,concentration,and development of high-tech industries and promote high-quality economic development. |
