基于环境绩效的长三角都市圈全要素能源效率研究

Research on Total-factor Energy Efficiency of Metropolitan Regions of Yangtze River Delta Based on Environmental Performance

本文运用"多投入—多产出"的DEA模型,以环境生产函数(EPF)和环境方向距离函数(EDDF)为基础,将污染作为生产过程产生的负产出纳入生产理论,将传统的生产技术扩展为环境生产技术,对长三角都市圈城市群1996—2008年全要素能源效率及其成分进行了测度,并对能源效率及其成分的影响因素进行了实证分析。本文发现,在环境约束下,能源的过度使用以及废气的过度排放导致长三角都市圈能源效率增长率和能源使用技术效率增长率的降低,而忽视能源使用减排技术的提高导致能源使用技术进步增长率的降低。累积的技术效率增长率、人均GDP、单位GDP废气排放量、技术进步程度、FDI、人均能源使用量对能源效率有不同程度的影响。技术效率增长率、技术进步增长率、人均GDP、工业产值占比、单位GDP废气排放量对能源效率增长率有不同程度的影响。

Handling the DEA model of ＂muhiinput-multioutput＂, based on environmental production functions and environmental directional distance functions, bringing pollution into production theory as byproduct of production process, extending traditional production technique into environmental production technique, this paper measures the total-factor energy efficiency of Metropolitan Regions of Yangtze River Delta and its composition during 1996--2008, and empirically analyzes their influencing factors. This paper finds out, under environmental restriction, energy overspend and excessive discharge of exhaust gas brought out the decline of growth rate of energy efficiency and technical efficiency of energy use, and neglecting the elevation of energy use of emission reduction resulted in the decline of growth rate of tecl＇,nique of energy use. Accumulative growth rate of technical efficiency, per capita GDP, volume of exhaust emission of unit GDP, progressive degree of technique, FDI and per capita amount of energy have a varying degree effect on the energy efficiency. Growth rate of technical efficiency, growth rate of technical advancement, per capita GDP, proportion of industrial production and volume of exhaust emission of unit GDP have a varying degree effect on the growth rate of energy efficiency.
