资源环境约束对国有企业效率的影响

Effects of Resources and Environment Constraints on State-owned Enterprises

经济结构的改善将极大地提升国有企业和非国有企业的ML指数,文章基于1985—2014年分省级面板数据,利用DDF-ML指数对资源环境约束下的国有企业全要素生产率进行测算。研究发现:国有企业的M指数和ML指数在1994年后有了较大幅度提高,但前者的增长幅度大于后者;考虑资源环境约束后,国有企业与非国有企业之间的效率差异显著缩小,且呈现出明显的区域特征(东部>中部>西部)。本文探讨不同所有制企业ML指数差异变化的原因,发现市场化水平和开放度的提高对缩小差异起着重要作用,而经济结构、工业污染治理强度和政府干预则会提高ML指数差异。

This paper uses the DDF- ML index to calculate the efficiency of the SOEs constrained by resources and environment, based on the provincial data from 1985 to 2014. We show that both of the SOE＇s M index and ML index have improved since 1994, but the former is larger than the latter. In addition, when considering the impacts of resources and environment, the efficiency differences between SOE and NSOE decrease, and exhibit distinct regional characteristics. We investigate the reasons of the tendency. The results suggest that the improvement of marketization and opening degree are positively related to the differences between SOE and NSOE, while economic structure, intensity of industrial pollution control, and government intervention is negatively related to the differences. The study provides revelation for measuring SOE efficiency and optimizing the industrial structure under the China＇s New Normal.
