摘要
利用2010—2019年我国260个地级市面板数据,在考虑能源投入和非期望产出的情况下,运用SBM方向性距离函数构建全局生产率指数对城市绿色全要素生产率进行测度,实证检验了外商直接投资对地级市绿色全要素生产率的影响,并进一步分析外商直接投资与绿色自主创新对绿色全要素生产率的作用机制。结果表明:(1)全国层面的外商直接投资会通过降低绿色技术进步水平进而显著降低地级市绿色全要素生产率水平。外商直接投资强度每提升1%,绿色全要素生产率水平平均下降4.1%。(2)区域层面的外商直接投资对于我国东部、中部、西部城市群的绿色全要素生产率水平均有抑制作用;对于东部和中部城市群的抑制是通过降低绿色技术进步水平实现的;对于西部城市群而言,则是通过降低绿色技术效率进而降低绿色全要素生产率。(3)外商直接投资与绿色创新的交互项系数显著,并且可以通过作用于绿色自主创新间接影响到绿色全要素生产率水平,交互—中介作用显著;门槛检验结果表明,外商直接投资数量的增加会扭曲绿色自主创新对绿色全要素生产率的正向影响,外商直接投资的负向“环境—技术”溢出效应显著。
Based on the panel data of 260 prefecture level cities in China from 2010 to 2019,considering energy input and unexpected output,by using the SBM directional distance function,this paper constructs GlobalMalmquist-lunberger index(GML index)to measure urban green total factor productivity,tests the impact of foreign direct investment(FDI)on prefecture level cities’green total factor productivity(GTFP)level empirically,and further analyses the mechanism of FDI and green independent innovation on GTFP.The results show that:Firstly,at the national level,FDI inflows will significantly reduce the GTFP level of prefecture level cities by reducing the level of green technology progress.When the intensity of foreign direct investment increases by 1%,the level of green total factor productivity decreases by 4.1%on average.Secondly,at the regional level,FDI inflows can inhibit the gtfp level of urban agglomerations in eastern,central and western China.The inhibition of the eastern and central urban agglomerations is realized by reducing the level of green technology progress while for the western urban agglomeration,it reduces GTFP by reducing the efficiency of green technology.Thirdly,the interaction coefficient between FDI and green innovation is significant and can indirectly affect the level of green total factor productivity through acting on green independent innovation.The threshold test results show that the increase of FDI inflow will distort the positive impact of green independent innovation on GTFP,which further shows that the negative spillover effect of foreign direct investment is significant.
