Abstract: Under the open and green development concept, this study selects panel data from 30 provinces(municipalities and autonomous regions) across the country from 2008 to 2007, uses the super-efficiency SBM model to measure the eco-efficiency of China′s industry, and uses the Spatial Dubin Model to empirically test the relationship among environmental regulations portfolio,FDI structure and industrial eco-efficiency. The results show that the industrial ecological efficiency of China is declining and the regional gap is increasing, especially in the eastern regions,and the spatial distribution is characterized by “club” agglomeration:most of the provinces with high efficiency are developed in the eastern coastal areas, while the rest of the provinces are medium efficiency and low efficiency, which are distributed in the underdeveloped areas of the central and western regions;formal environmental regulation and informal environmental regulation have positive effects on industrial eco-efficiency and the promotion of formal environmental regulation is greater;the two types of environmental regulation have significant effects on the optimization of FDI structure, and improve industrial eco-efficiency by improving the quality of FDI and forcing innovation effect;the direct and indirect effects of formal environmental regulation on industrial eco-efficiency are established in all regions, while the direct promotion and indirect optimization of informal environmental regulation on industrial eco -efficiency are established in the eastern and central regions, but not in the western regions.Therefore, we should strengthen the environmental supervision of polluting industries, avoid the entry of polluting FDI, improve the foreign investment environment, optimize the public participation system, and enhance the public awareness of environmental protection.

Key words: industrial eco-efficiency;environmental regulation portfolio, FDI structure
