空间集聚、企业更替与生产率

Spatial Agglomeration,Firm Turnover,and Productivity

文章基于中国工业企业微观数据的实证分析结果,验证了企业更替是经济空间集聚改善生产率的重要机制,并发现空间集聚和企业更替与生产率之间都呈现倒U型关系。而时间异质性和区域异质性分析表明,随着中国开放程度和市场化水平的提高,空间集聚的经济性愈发显著,且生产率提高的企业更替机制始终具有重要作用。据此,地方政府应进一步深化改革开放,提高市场化水平,着力培育企业进入与退出的公平环境,完善资源优化配置的市场内生机制,更好发挥空间集聚的经济性,实现地区生产率的持续改善。

Based on the empirical analysis of the micro data of Chinese industrial enterprises,this paper verifies that firm turnover is an important mechanism for economic spatial agglomeration to improve productivity,and finds that there is an inverted U-shaped relationship between spatial agglomeration,firm turnover,and productivity.The analysis of time heterogeneity and regional heterogeneity shows that with the improvement of China’s openness and marketization level,the economy of spatial agglomeration becomes more and more significant,and the replacement mechanism of enterprises with higher productivity always plays an important role.Therefore,the local government should further deepen the reform and opening up,improve the level of marketization,focus on cultivating a fair environment for enterprises to enter and exit,and improve the market endogenous mechanism for the optimal allocation of resources,so as to give full play to the economy of spatial agglomeration and realize the continuous improvement of regional productivity.
