Resumen

This paper employs the EBM model and the Spatial Durbin Model(SDM) to describe the spatial characteristics and influencing factors of the 27 cities’ eco-efficiency in China’s Yangtze River Delta from 2003 to 2018. We find that the overall 27 cities’ eco-efficiency in China’s Yangtze River Delta fluctuates slowly, and the spatial difference of the ecological efficiency of the 27 cities in this area is obvious, showing the distribution characteristics of “East is better than west”. The findings show that PGDP, FDI, industrial structure (IND), and population density (POP) have a significant positive correlation with the eco-efficiency of this area. On the contrary, there is a significant negative correlation between greening level (GRE) and ecological efficiency, but the level of technological innovation is not significant.
