Based on the panel data of 48 cities of three coastal metropolitan agglomerations in eastern China from 2003 to 2016, this paper uses the super-efficient SBM model with unexpected output to measure their environmental regulation efficiency, and combines the coefficient of variation, Gini coefficient, spatial autocorrelation and GLS model to analyze the spatial evolution characteristics of urban agglomerations'environmental regulation efficiency. On this basis, the paper identifies the inefficient operation cities of environmental regulation, and explores the driving factors of the change of environmental regulation efficiency of urban agglomerations. The results show that: (1) The efficiency of environmental regulation of Beijing-Tianjin-Hebei urban agglomeration is the most significant improvement; the efficiency of environmental regulation of the Yangtze River Delta urban agglomeration is significantly reduced; and the efficiency of environmental regulation of the Pearl River Delta urban agglomeration is obviously superior to the other two major urban agglomerations.(2) There are obvious internal differences in the efficiency of environmental regulation among the three mega-cities, the Pearl River Delta mega-cities are the most prominent, and the risk of regional environmental governance is higher.(3) Pearl River Delta urban agglomeration is a spatial agglomeration area with high environmental regulation efficiency, and the spatial spillover effect is significant; Beijing-Tianjin-Hebei and Yangtze River Delta urban agglomeration is a spatial agglomeration area with low environmental regulation efficiency, and the spatial spillover effect is not significant. (4) Economic development level, industrial structure, market environment, urbanization level and opening level are the influencing factors of environmental regulation efficiency of coastal urban agglomerations.
