Abstract

Yu, S.D.; Yu, W.Y.; Chen, T.; Wang, H.Y., and Zhang, S.J., 2020. Spatial-temporal distribution and convergence of eco-efficiency of industrial enterprises in coastal provinces of China. In: Qiu, Y.; Zhu, H., and Fang, X. (eds.), Current Advancements in Marine and Coastal Research for Technological and Sociological Applications. Journal of Coastal Research, Special Issue No. 107, pp. 303-307. Coconut Creek (Florida), ISSN 0749-0208.

The dynamic trends and convergence of eco-efficiency of industrial enterprises was analyzed using the super efficiency DEA model (US-DEA) with undesirable output and the σ convergence model based on the panel data of industrial enterprises in coastal provinces in China from 2007 to 2017 in accordance with the evaluation characteristics of eco-efficiency of industrial enterprises in coastal provinces. The spatial autocorrelation model was applied to measure the spatial correlation of eco-efficiency of industrial enterprises. The research results are as follows: (1) The static analysis shows that there are great differences in the dynamic mean of the eco-efficiency of industrial enterprises in coastal provinces, indicating that there is room for the improvement of the eco-efficiency of industrial enterprises in some provinces. (2) The static analysis shows that the eco-efficiency of industrial enterprises in coastal provinces are constantly rising, reflecting that the general ecological improvement tendency of industrial enterprises in coastal provinces is quite significant. (3) The convergence analysis of eco-efficiency of industrial enterprises in coastal provinces shows that there is no convergence trend in eco-efficiency of industrial enterprises in coastal provinces, indicating that the eco-efficiency is instable. (4) The spatial analysis of the correlation status of eco-efficiency of industrial enterprises in coastal provinces shows that the eco-efficiency has no correlation and has a dispersed distribution.
