Abstract:

How to solve the problem of environmental pollution in China's urbanization is one of the key issues that bear heavily on the healthy and sustainable development of urbanization. To explore the eco-efficiency in the process of the urbanization and the mechanism of urbanization and eco-efficiency, this paper calculates the eco-efficiency of 30 provinces in China from 2003 to 2012 by using the super efficiency DEA and analyzes internal mechanism of eco-efficiency and urbanization by building Spatial Panel Durbin Model. The empiri-cal results show that there is a strong negative correlation between urbanization and eco-efficiency and a negative spillover effect to other regions. When urbanization increases 1%, the average total spatial spillover effect is -0.485%. The model also proves that there is little effect of sewage charges to improve the quality of the environment. The spillover effect of urbanization on eco-efficiency is reflected mainly through the industrial structure optimization and the technology improvement. Therefore, China should adjust industrial structure and in-crease technological investment when making plans of urbanization development strategy. Meanwhile China also should establish effective communication and cooperation mechanism between different regions and optimize spatial distribution of polluting enterprises.

Key words: eco-efficiency, urbanization, spatial spillover effects, spatial Durbin model
