Abstract Environmental regulation, industrial agglomeration and ecological efficiency in Bohai Economic Rim are explored in this thesis based on the panel data of 44 cities from 2009 to 2016, DEA model and differential GMM estimation method of dynamic panel. The results indicate that: ① Environmental regulation intensity and ecological efficiency in Shandong, Beijing, Tianjin and Hebei Province showed an upward trend while that in Hebei Province was in a downward trend. The location entropy in most cities of Liaoning, Beijing, Tianjin and Hebei Province had obvious downward trend. The location entropy in Shandong province was not obvious, and in most cities showed a trend of fluctuation. ② The lag coefficient of ecological efficiency in Bohai Economic Rim was significantly positive. The impact of environmental regulation on ecological efficiency was positively correlated, and the impact of industrial agglomeration on ecological efficiency was negatively correlated. The interaction between industrial agglomeration and environmental regulation was positively related to the ecological efficiency. ③ The impact of economic development level, population size and foreign investment level on ecological efficiency was significantly positive, and the impact of human capital on ecological efficiency was not significant. Therefore, environmental regulation and industrial agglomeration were crucial to the improvement of ecological efficiency, and economic development, population size and foreign investment level were also important factors to improve ecological efficiency.
