数字经济发展与流通业绩效优化--来自大数据综合试验区的证据

The Development of Digital Economy and the Performance Optimization of Circulation Industry:Evidence from the Big Data Comprehensive Pilot Area

文章采用空间双重差分(SDID)模型对数字经济与流通业绩效的动态关联及其内在传导机制进行考察。研究发现,以大数据综合试验区建设所表征的数字经济发展对于流通绩效提升具有显著的促进作用,但这一促进作用具有明显的时滞性,在政策实施1~2年后才显现;数字经济发展对于周边地区流通业绩效优化同时具有显著的正向溢出效应;数字经济发展能够通过市场一体化和劳动力要素优化配置等途径实现流通业绩效优化。据此,研究认为应着力推动数字经济建设与流通业发展的深度融合,从而加速流通业转型发展和质效提升。

The paper uses the spatial double difference(SDID)model to investigate the dynamic relationship between the digital ec-onomy and the performance of the circulation industry and its internal transmission mechanism.The results show that the development of the digital economy represented by the construction of the big data comprehensive pilot zone has a significant boosting effect on the improvement of circulation performance,while such boosting effect has significant time lag,which appears after the implementation of the policy 1 to 2 years.The development of the digital economy also has a significant positive spillover effect on the optimization of circulation performance in surrounding areas.Market integration and the optimal allocation of labor factors are the main paths that the development of the digital economy optimizes the performance of the circulation industry.Therefore,this paper suggests that,to accelerate the transfo-rmation and development of the circulation industry,the digital economy and the circulation industry should be deeply integrated.
