基于全要素能源效率的天津市能源回弹效应研究

Study on Tianjin Energy Rebound Effect Based on Total Factor Productivity

针对天津市1997-2011年的能源利用状况,基于DEA-Malmquist指数法和C-D生产函数法,建立能源回弹效应模型,测算天津市的全要素能源效率,进而对能源回弹效应进行测算。结果表明天津市能源回弹效应在不同时期存在着不同程度的波动,但总体上呈现下降趋势。由于能源回弹效应的存在,在通过技术进步提高能源利用效率同时,应当改变经济的增长方式,运用政府管制、能源价格改革和产业结构调整等手段降低能源消费来控制能源回弹效应,达到节约能源的目的。

According to Tianjin energy utilization in 1997-2011,we established the rebound effect model based on DEA-Malmquist index method and C-D production function,to evaluate the total factor of Tianjin energy efficiency and the energy rebound effect.Measuring results showed that Tianjin energy rebound effect exists in different periods with different degree of volatility.On the whole,it showed a trend of decline.Due to the energy rebound effect,we use technological progress to improve efficiency.At the same time,we should change economic growth mode and apply the method of the government controls,the energy price reform and adjustment of industrial structure,truly achieve the purpose of saving en-ergy.
