Abstract: From the perspective of quantity and quality of FDI, this paper empirically tests the relationship between FDI and industrial ecological efficiency by using 30 provincial panel data and simultaneous equation models from 2001 to 2016 on the basis of using super-efficiency SBM model to estimate industrial ecological efficiency in China.The results show that: during the sample period, the overall industrial ecological efficiency of China is deteriorating, and the gap between regions is widening gradually, and the spatial distribution pattern of gradient decreasing from east to middle to west is presented. From the direct point of view, the quantity of FDI has no significant impact on China′s industrial ecological efficiency, while the quality of FDI has a positive spillover effect, and the industrial ecological efficiency has a positive effect on the quantity and quality of FDI.From the indirect perspective, the quantity of FDI is positively correlated with the intensity of environmental supervision, which produces positive and negative externalities for domestic industrial structure and economic development. In the game process of positive and negative externalities, the impact on industrial ecological efficiency is not significant. The quality of FDI improves industrial ecological efficiency by improving the level of economic development and weakening the negative effects of environmental supervision. Therefore, it is necessary to strengthen the screening of FDI quality, attract the entry of FDI quality enterprises, and create a good investment environment to form a virtuous circle of mutual promotion between FDI and industrial ecological efficiency.

Key words: FDI quality, FDI quantity, industrial ecological efficiency, super-efficiency SBM
