The Effect of FDI on Ecological Efficiency in China's Regional Eco-efficiency under the Third-Country Effects

The paper selects China's statistical data from 2004 to 2016. From the perspective of Third- Country Effects, it uses DEA and spatial measurement analysis methods to study the impact of FDI on China's regional ecoefficiency. The results show that compared with the Third- Country Effects, the impact of FDI on ecoefficiency has a significant change considering the Third- Country Effects. FDI inflows in the eastern region and adjacent regions will have a significant positive impact on the eco-efficiency of the region. In the western region, the impact of FDI accumulation in its adjacent regions on the ecological efficiency of the region also shows a significant positive change, but the level of significance is smaller than that of non-Third-Country Effects and its elasticity coefficient also becomes smaller. Then, based on the empirical analysis results, the suggestions for improving the regional ecological efficiency are put forward, which has certain practical significance for the sustainable development of the regional economy.
