FDI对佛山市内资制造业全要素生产率的影响研究——基于技术溢出效应的视角

Research on the Influence of FDI to TFP of Domestic Manufacturing Industry in Foshan--From the Perspective of Technology Spillover Effect

采用数据包络分析法(DEA)测算了佛山市制造业2000—2018年的Malmquist指数,并进一步将其分解为技术进步和效率变化两个因子。基于技术溢出效应视角,构建的面板数据模型同时包含水平溢出效应和垂直溢出效应两方面解释变量。研究发现外商直接投资主要通过行业内及行业间的溢出效应,对佛山市内资制造业企业技术进步起促进作用,从而整体上提升内资企业的全要素生产率,FDI在行业内、行业间的前后向关联效应对佛山市内资制造业企业的效率改善作用效果则是不一致的。

The data envelopment analysis(DEA)method is used to calculate the mamlquist index of Foshan manufacturing industry in 2000-2018 in this paper,and it is divided into two indicators:technological progress and efficiency change.Based on the perspective of technology spillover effect,a panel data model including horizontal spillover effect and forward and backward correlation effect is constructed.It is found that the entry of foreign capital promotes the technological progress of manufacturing industry in Foshan,but inhibits the improvement of efficiency;FDI has a significant positive impact on the technological progress of downstream domestic manufacturing industry,but has a significant inhibitory effect on the improvement of efficiency;FDI has a significant positive effect on the total factor productivity and technological progress and efficiency progress of upstream domestic manufacturing enterprises.
