基于随机前沿模型的对外开放与能源技术效率提升

The Impacts of Opening-up to the Outside on Energy Technical Efficiency

设定能源技术效率作为有效反映能源利用效率的指标,通过设定带非效率影响的随机前沿函数,利用1995-2007年中国29个省(自治区、直辖市)的面板数据,对我国对外开放与能源技术效率的提升程度进行分析,认为对外开放程度的加深促进了我国能源技术效率的提高,出口贸易、进口贸易和FDI均起着积极作用。但是,东、中、西部地区在能源技术效率上存在着明显差距,东部地区最高,中部地区次之,西部最低。

This paper regards energy technical efficiency as the reasonable index reflecting the efficiency of energy use. It adopts a stochastic frontier model, which incorporates a model for technical inefficiency effects, and uses the simultaneous estimation of maximum likelihood to estimate and evaluate the impact of opening-up on the energy technical efficiency in China by using panel data of 29 provinces in China during 1999 to 2007. The conclusions include： the energy technical efficiency of all provinces in China improve every year; export trade, import trade and FDI play a crucial role in improving energy technical efficiency; there is a clear gap between different areas：the eastern areas has the highest energy technical efficiency,followed by the middle areas ,and western areas is the last.
