本文分别计算了1989~2008年期间中国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。和传统忽视污染排放的M全要素生产率相比,考虑环境污染非合意产出的ML全要素生产率增长,不仅反映了合意产出(GDP)的增加,而且还反映了污染排放的减少,体现了增长的可持续性。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。和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。进一步通过三阶段DEA产出调整和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。
In this paper, the Mannich-Lennig (ML) and the traditional Mannquist (M) TFP index of 30 provinces in China from 1989 to 2008 were calculated respectively. Compared with the M total factor productivity of traditional neglect of pollution discharge, ML total factor productivity growth, which takes into account the non-consensual output of environmental pollution, not only reflects the increase of desired output (GDP), but also reflects the reduction of pollution discharge, The sustainability of growth. Empirical studies show that the growth of M total factor productivity, which ignores the traditional pollution emission, is overestimated if the environmental factors are taken into account. Like most developing countries, the main reason why China’s total factor productivity is overestimated is directly related to the level of environmental regulation. Further, through the three-stage DEA output adjustment and ML total factor productivity simulation and test, it is found that the implementation of environmental regulation in China is extremely loose in general and the strict implementation of environmental regulation is conducive to the growth of total factor productivity of China’s economy. It is precisely because the implementation of environmental regulations lax, it leads to China’s economy ML total factor productivity is very sensitive to environmental constraints.
