物流效率对全要素生产率的影响研究

Research on the Infl uence of Logistics Effi ciency on Total Factor Productivity

本文基于2001—2016年的省级面板数据,构建双固定效应模型和门槛模型研究物流效率对全要素生产率的影响。结果发现,物流效率对全要素生产率有显著的正向影响。东部、中部和西部地区物流效率对全要素生产率的影响存在异质性。从分时段的回归结果来看,物流效率对全要素生产率都存在正向影响,表明物流业对全要素生产率的基础性、战略性和先导性作用;制度质量为门槛变量时,物流效率对全要生产率存在单一门槛效应,表明物流效率对全要素生产率存在先抑后扬的作用。

Based on the provincial panel data from 2001 to 2016,this article constructs a dual fi xed eff ects model and a threshold model to study the impact of logistics effi ciency on total factor productivity.The results show that logistics effi ciency has a signifi cant positive impact on total factor productivity.There is heterogeneity in the infl uence of logistics efficiency on total factor productivity in eastern,central and western regions.According to the regression results of different periods,logistics efficiency has a positive impact on total factor productivity,indicating the basic,strategic and leading role of the logistics industry on total factor productivity;when institutional quality is a threshold variable,logistics effi ciency has a single threshold eff ect on total factor productivity,which is represented by the eff ect of logistics effi ciency on total factor productivity.
