摘要
本文运用1995～2006年中国210个主要地级市面板数据，首先采用DEA模型测算了城市全要素能源效率，然后分析了城市全要素能源效率变化特征，结果显示城市能源效率变动趋势呈现四个较为明显“倒U型”特征，城市间差距扩大转折点出现在2000年左右，而地区间城市差距存在一定的趋同性。最后采用Tobit模型分析了资源禀赋、产业结构、技术水平及其他政策因素与能源效率之间的关系，回归结果说明应区别对待不同因素在不同情况下引起能源效率变化中所起到的作用。
With the panel data of main Chinese 210 prefecture-level cities in 1995 -2006, the paper firstly measured Chinese cities Total Factor Energy Efficiency using CRS-DEA model; secondly, described the features of changes, The results shows changing trends of urban energy efficiency displayed 4 ＂inverted U＂ characteristics, a widening gap occarred in 2000 between cities, while There is a certain convergence between regional disparities. Urban energy efficiency levels are not stable, low efficiency and high input City will be the focus of energy-saving emission reduction. Finally, We use Tobit model to regress energy efficiency and resource endowment, industrial structure, technological and variety of policy factors, results indicate that different factors should be treated differently in different situations.
