Abstract: On the basis of a theoretical analysis of the disparate impact of environment regulation strength on FDI entry mode choice and on the regional green-technical innovation efficiency, this paper conducts an empirical test with China’s provincial penal data from 2008 to 2014 as the sample. The findings show that FDI is more inclined to enter the regions with more rigorous environment regulation by taking joint venture mode and to enter those regions with less rigorous environment regulation by taking single proprietorship. FDI with the joint venture mode will hinder the improvement of regional green technical innovation efficiency in the regions with more rigorous environment regulations, while FDI with the single-proprietorship mode will greatly promote the green technical innovation efficiency in regions with less rigorous environment regulation.

Key words: FDI entry mode; green technical innovation efficiency; environment regulation.
