摘要

本文提出了一种定向距离函数方法来衡量两种技术效率，这两种技术的特点是污染物的强可处置性和弱可处置性。环境效率指数定义为两种技术效率之比，反映了将污染物的强可处置性转化为弱可处置性的机会成本。利用2003 - 2009年中国284个地级及以上城市工业部门的投入产出数据，包括废水、二氧化硫和烟尘排放，将该方法应用于中国工业部门环境效率指数的测度。采用面板Tobit模型对影响环境效率的几个因素进行了研究。

Measuring the environmental efficiency of the Chinese industrial sector: A directional distance function approach

This paper presents a directional distance function approach to measure two technical efficiencies with respect to the two technologies characterized by strong and weak disposability of pollutants. The environmental efficiency index, defined as the ratio of the two technical efficiencies, reflects the opportunity cost to transform the strong disposability of pollutants into a weak one. The proposed approach is applied to measure the environmental efficiency index of the Chinese industrial sector, with the input and output data of the sector in 284 cities at the prefecture level and above in China from 2003 to 2009, including the emissions of wastewater, sulfur dioxide, and soot. Several factors of environmental efficiency are also investigated by using a panel Tobit model.
