新疆火电企业节能减排效率评价及影响因素分析

The Evaluation and Influencing Factors of Energy Conservation and Emission Reduction Efficiency of Xinjiang Thermal Power Enterprises

基于新疆26家年综合能耗在20万吨标准煤以上火电企业的实地调研数据,运用非期望产出松弛量测算的数据包络分析(SBM-DEA)模型测算了26家企业的节能减排效率值,通过Tobit模型实证探索了各火电企业的节能减排效率产生差异的原因。结果表明,新疆火电企业总体节能减排效率较低,其中北疆地区平均节能减排效率低于南疆地区;企业技术进步、成立时间、政府补贴及地区经济发展等因素均可显著提高火电企业的节能减排效率,针对研究结果从政府、企业两个层面提出相应对策建议。

Based on the field survey data of 26 thermal power enterprises with an annual comprehensive energy consumption of more than 200000 tons of standard coal in Xinjiang,the energy saving and emission reduction efficiency values of 26 enterprises were calculated by using the non-expected output SBM-DEA model,and the reasons for the differences in energy saving and emission reduction efficiency of various thermal power enterprises were empirically explored by using the Tobit model.The results show that the overall energy saving and emission reduction efficiency of Xinjiang thermal power enterprises is relatively low,and the average energy saving and emission reduction efficiency in northern Xinjiang is lower than that in southern Xinjiang.Factors such as technological progress,establishment time,government subsidies and regional economic development can significantly improve the energy conservation and emission reduction efficiency of thermal power enterprises.According to the research results,corresponding countermeasures and suggestions are put forward from the two levels of government and enterprise.
