基于DEA-Tobit的城市生态效率评价及影响因素研究--以江苏省为例
Research of the Evaluation of Urban Eco-efficiency and Its Influencing Factors Based on DEA-Tobit Model- A Case Study of Jiangsu Province
摘要
Abstract
In this paper, on the basis of DEA-Tobit model, super-efficiency DEA model was used to evaluate the industrial eco-efficiency of 13 cities in Jiangsu Province as well as its southern, central and northern parts from 2009 to 2013. Tobit model was also applied to discuss how urbanization rate, industry structure and environmental regulation affect such efficiency value. The results showed that the overall urban industrial eco-efficiency of Jiangsu Province was in a middle and upper level but with larger differences between the regions. That was, the central part performed better than the southern part, and the southern part performed better than the northern part. Excessive consumption of industrial water and industrial lands and excessive emission of industrial exhaust were the main causes limiting the improvement of urban industrial eco-efficiency in Jiangsu Province. Improvement of urbanization rate had a positive influence on the urban industrial eco-efficiency. However, industrial restructuring weakly inhibited it and the impact of environmental regulation on it was not significant either.关键词
