摘要
利用2010年我国中部六省的面板数据,运用投入导向的超效率DEA模型计算其2010年的节能减排效率值,然后采用Tobit模型对影响节能减排效率的各因素进行具体分析。结果表明:2010年中部六省中只有河南、湖北和湖南是节能减排DEA有效的决策单元;中部六省节能减排整体水平不高,节能减排潜力很大;各省的经济规模和排污费收入与节能减排效率存在明显的正相关关系,工业产值比重和煤炭资源储量与节能减排效率存在明显的负相关关系。
Using the panel data of six provinces in central China in 2010,this paper uses the input-oriented super-efficiency-DEA model to calculate the efficiencies of energy saving and emission reduction of six provinces in central China,then uses the Tobit model to analyze the influencing factors of energy saving and emission reduction efficiency.The results show as follows：in 2010,the energy saving and emission reduction efficiencies of six provinces are low on the whole,only Henan,Hubei and Hunan＇s energy-saving emission reduction are effective,so the potential is great;there exist the significant positive correlations between energy saving and emission reduction efficiency and economy scale as well as pollution charge,and industrial structure and coal resource reserve are negatively related to energy saving emission reduction efficiency.
