要素流动与全要素生产率——基于空间杜宾模型分析

Factor flow and total factor productivity:Based on spatial Dubin model

本文基于中国2003—2019年的省际面板数据,使用DEA-Malmquist指数法测算地区全要素生产率,采用空间杜宾面板模型(SDPM)实证检验了要素流动对全要素生产率的影响。研究结果表明:无论是要素流入地还是流出地,要素流动皆能够显著促进全要素生产率增长;地区资本强度对全要素生产率具有显著促进作用,基础设施建设对邻近地区具有正向溢出效应;技术要素流入能够显著促进当地全要素生产率增长,劳动力与资本流动的作用并不显著。本文理论假说在多种空间权重矩阵与IV-GMM估计下依旧稳健。因此,应充分重视地区间要素流动,充分发挥资源配置优化对全要素生产率的促进作用。

Based on China s inter-provincial panel data from 2003 to 2019,this paper uses the DEA-Malmquist index method to measure regional total factor productivity,and uses the Spatial Durbin panel model to test the impact of factor flow on total factor productivity.The results show that:Factor flow can significantly promote regional total factor productivity growth in both inflow and outflow regions.Regional capital intensity has a significant promoting effect on total factor productivity,and infrastructure construction has a positive spillover effect on neighboring regions.The inflow of technological factors can significantly promote the growth of local total factor productivity,but the effect of labor and capital flow is not significant.The theoretical hypothesis in this paper remains credible under various spatial weight matrices and IV-GMM estimates.Therefore,we should attach importance to inter-regional factor flow and give full play to the promoting effect of resource allocation optimization on total factor productivity.
