摘要
本文运用1995—2006年中国210个主要地级市的面板数据,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差异特征,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。城市能源效率水平并不稳定,低效率高投入城市将是节能减排的重点。本文最后采用Tobit模型分析了资源禀赋、平均气温、产业结构、技术水平及各类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条件下引起能源效率变化的影响。
With the panel data of main Chinese 210 prefecture-level cities in 1995--2006, this paper measured Total Factor Energy Efficiency using CRS-DEA model and described the features of regional differences. The results shows changing trends of urban energy efficiency displayed 4 ＂inverted U＂ characteristics, a widening gap occurred in 2000 between cities. Low efficiency and high input cities will be the focus of energy-saving. Finally, We use Tobit model to regress energy efficiency and resource endowment, temperature, industrial structure, technological and variety of policy factors, the results indicate that different factors should be treated differently in different situations.
