鄱阳湖生态经济区战略性新兴产业环境技术效率测度研究

将 Global Malmquist-Luenberger 指数与方向性距离函数相结合，测算了2009-2012年鄱阳湖生态经济区十大战略性新兴产业的环境技术效率，并将环境全要素生产率的变动情况分解为技术进步指数和效率改进指数2个方面，最后运用面板 Tobit 模型对影响鄱阳湖生态经济区战略性新兴产业环境技术效率的因素进行分析。研究结果表明:鄱阳湖生态经济区十大战略性新兴产业环境技术水平总体偏低，各产业环境技术效率差异较大；环境全要素生产率的增长主要源于技术进步；外商直接投资、技术进步和固定资产投资对战略性新兴产业环境技术效率有显著正影响，产业产出和环境管制力度对战略性新兴产业环境技术效率有负影响。

The Research on the Measurenent of Environnental Technical Efficiency in the Strategic Energing Industries of the Poyang Lake Eco-Econonic Zone

The environmental technical efficiency and environmental total factor productivity change of the strategic emerging industries in Poyang Lake Eco-economic Zone over the period of 2009 to 2012 are evaluated by applying SBM directional distance function and Global Malmquist-Luenberger index method. The environmental total factor productivity change is decomposed into 2 factors:technical progress and efficiency change,and using panel Tobit model for empirical analysis on the relative influence of factors that affect environment technical efficiency. Calcula-tion results show that the environment technical efficiencies of ten strategic emerging industries are low and have big difference. The growth of environmental total factor productivity change mainly comes from technical progress. For-eign direct investment,technical progress and fixed investment all have a significant positive impact on environmen-tal technology efficiency,but the output of industries and the level of environmental regulation both have a negative impact on environmental technology efficiency.
