黑龙江省四煤城绿色全要素生产率增长研究——基于与本省各地市的比较研究

以黑龙江全省及省内十三个地市构建生产前沿面,采用基于方向性距离函数的DEA方法,测算四煤城绿色全要素生产率增长及其增长源泉,得出结论:经历了一段时间的低水平甚至负向增长后,2014年,四煤城绿色全要素生产率全部实现正向增长,并高于全省平均水平。依据四煤城绿色全要素生产率的增长源泉存在的差异,给出了提高四煤城绿色全要素生产率的对策建议。

Using the data of Heilongjiang Province and the thirteen cities in the province to build production frontier, based on the DEA method of directional distance function, this paper measures the growth rate of green total factor productivity and the source of its growth. It finds that, after a period of low level or even negative growth, in 2014, four coal city green total factor productivity all to achieve positive growth, and higher than the provincial average. There are differences in the source of green total factor productivity growth in the four coal cities. This paper also gives the productivity of the four coal cities.
