FDI对中国农业全要素生产率的空间溢出效应
Spatial Spillover Effect of FDI on Total Factor Productivity of Chinese Agriculture

利用空间杜宾模型和1999-2014年中国农业省际面板数据，实证检验FDI对中国农业TFP的空间溢出效应。研究发现：FDI对农业TFP存在显著的空间溢出效应，即FDI不仅能促进本地区TFP提升，还能促进相邻地区TFP提升；FDI对本地区和相邻地区农业技术效率改进都具有抑制作用；FDI对本地区的农业技术进步具有正向促进作用，但对相邻地区的农业技术进步影响不显著。
Most of the research on FDI and agricultural TFP neglects the spatial correlation between the regions, which tends to lead to the error of the study results. This paper studies the effect of spatial spillover effect of FDI on agricultural TFP by using Spatial Durbin Model and 1999-2014 provincial panel data. The results show that the spatial spillover effect of FDI on agricultural TFP is significant, namely the FDI can promote the TFP growth not only in the region, but also in the adjacent regions. FDI has an inhibitory effect on the improvement of agricultural technology efficiency in the region and adjacent areas. FDI has positive effect on agricultural technology progress in the region, but it has no significant effect on agricultural technology progress in the adjacent regions.
