本文分别计算了1989至2008期间中国30个省际地区的曼奎斯特-伦伯格(ML)与传统曼奎斯特(M)全要素生产率指数,实证研究表明如果考虑环境因素约束,传统忽视污染排放的M全要素生产率增长被高估;与大多数发展中国家一样,中国经济M全要素生产率被高估的主要原因与环境规制水平直接相关;通过三阶段DEA产出调整、ML全要素生产率模拟和检验后,发现中国环境规制的实施总体上是极其宽松的,而严格的环境规制实施有利于中国经济ML全要素生产率的增长,正是由于环境规制实施不严才导致中国经济ML全要素生产率对环境因素约束非常敏感。
The paper calculates the Malmquist- Luenberger (ML) and the traditional Malmquist (M) index in total factor productivity of China's 30 provincial regions from 1989 to 2008. The results of empirical analysis show that, if tak- ing environmental factors into account, the traditional Malmquist total factor productivity growth, which ignores emis- sions, is overestimated. The same as most of the developing countries, the overestimation of Malmquist productivity re- lates directly with environmental regulations level. After further three - stage DEA adjustment of outputs and simulation of ML productivity growth tests, we find that the enforcement of environmental regulations is lax in general, and the more stringent enforcement of environmental regulations will benefit the total factor productivity growth of China's economy. It is the lax stringent enforcement of environmental regnlations that makes the total factor productivity growth of China's economy be sensitive to constraints of environmental factors.
