考虑环境因素的省级技术效率排名(1999—2005)

Provincial Technology Efficiency Ranking with Environment Factors(1999—2005)

近年来，一些生产率模型已经开始考虑环境因素的影响。本文在中国省级数据的基础上，采用以方向性距离函数为表述的全要素生产率模型，对省级生产率绩效度量中的“技术效率”指标在考虑了环境因素的情况下进行重新排名。我们的研究经验表明，本文所使用的模型，既考虑环境因素的影响，又继承了传统生产率分析技术的系统性和结构性框架，相对于目前流行的直观的绿色GDP推算方法有着较为广泛的应用前景。

In recent years, some productivity models have started to consider the influence of environmental factors. This study re-ranks technical efficiency of Chinese provinces, using directional distance function approach. It takes account of environmental factors while implementing the DEA methodology. The study demonstrates that this type of models can produce efficiency rankings that are significantly different from the standard DEA model, and opens new avenues for the studies of total factor productivity when environmental factors are involved.
