环境技术效率、污染治理与环境绩效——基于1998—2012年中国省级面板数据的分析

Technical Efficiency of Environment,Pollution Abatement and Environmental Performance——Based on 1998—2012 Provincial Panel Data Analysis

本文使用1998—2012年省级层面的工业统计数据测算出中国的环境技术效率并在此基础上探讨中国环境污染治理的特点。实证结果验证了EKC曲线和"重组假说"的存在。研究结果表明:环境技术效率、污染治理投资均与环境绩效正相关,且环境技术效率是有效治理环境污染的最重要因素;工业废水治理存在规模递增效应,但是工业废气以及工业废物的治理效果却不显著;此外我们还发现(环境曲线)的拐点明显低于发达国家水平,这表明中国的环境治理存在后发优势。

The provincial industrial statistics panel data from 1998 to 2012 is used to calculate the technical efficiency of Chinese environment,on the basis of which investigates the characteristics of China's environmental governance,the empirical results verify the EKC curve and the existence of the 'relinking' hypothesis,the empirical results show that the technical efficiency of environment and abatement effort are positively related to environmental the performance.It can be found that the increasing returns to water pollution abatement,however waste gas and solid waste pollution abatement are not significant.The inflection point of Chinese EKC is significantly lower than developed countries and we infer that Chinese Pollution abatement holds the advantage.
