外商直接投资对长三角城市群绿色全要素生产率的影响

The influence of foreign direct investment on green total factor productivity in the Yangtze River delta urban agglomeration

基于2008~2019年的面板数据,以长三角城市群为研究样本,采用SBM-Malmquist模型测度了长三角26个核心城市的绿色全要素生产率,运用面板回归模型实证检验了外商直接投资对长三角城市群绿色全要素生产率的影响。结果显示:考察期内外商直接投资显著促进了长三角城市群绿色全要素生产率的增长;经济发展水平、经济密度和对外贸易是促进绿色全要素生产率提升的重要因素。

Based on the panel data from 2008 to 2019 while taking the Yangtze River delta urban agglomeration as the research sample,the SBM-Malmquist model is used to measure the green total factor productivity of 26 core cities in the Yangtze River delta,and the panel regression model is used to empirically test the influence of foreign direct investment(FDI)on the green total factor productivity in the Yangtze River delta urban agglomeration.The results show that FDI significantly promoted the growth of green total factor productivity in the Yangtze River delta urban agglomeration during the sample period.The economic development level,economic density and foreign trade are the important factors to promote the improvement of green total factor productivity.
