基于随机前沿模型的新疆十五个地州市碳排放效率评价

Evaluation of Carbon Emission Efficiency for Fifteen Prefectures of Xinjiang Based on Stochastic Frontier Analysis

结合新疆十五个地州市2000～2011年的能源消费数据,首先对新疆十五个地州市的碳排放量进行了计算,其次运用谢泼德能源距离函数的随机前沿分析方法,对新疆十五个地州市2000～2011年的碳排放效率进行测算,2011年的数据显示,新疆十五个地州市碳排放效率排在前三位分别是塔城（0.833）、克拉玛依（0.810）、博州（0.733）,排在后三位的分别是克州（0.481）、石河子（0.459）、和田（0.428）,新疆碳排放效率平均水平为0.614.针对新疆高低碳排放区特点提出高碳稳速、低碳增效的政策建议.

In this paper, combined with energy consumption data of fifteen prefectures in Xinjiang from2000 to 2011, firstly we estimate carbon emission for fifteen prefectures of Xinjiang. Secondly based on stochastic frontier analysis, we calculate carbon emissions efficiency for fifteen prefectures of Xinjiang from2000 to 2011. According to the results of year 2011, the top three are Tacheng（0.833）, Karamay（0.810）,Bozhou（0.733）, the bottom three are Kezhou（0.481）, Shihezi（0.459）, Hotan（0.428）, and the average level is0.614. Therefore, we proposed keep steady speed in high carbon emission zones and increase energy efficiency in low carbon emission zones.
