在环境约束趋紧的背景下，选取京津冀、长三角和珠三角35个城市2005—2012年的面板数据，运用SBM—Undesirable模型对环境效率进行测算，应用泰尔指数从区际层面对环境效率差异进行衡量，并运用Tobit回归模型对环境效率的影响因素进行了研究。结果显示，我国三大城市群环境效率平均值的区域分布为：珠三角〉长三角〉京津冀；环境效率区域差异明显，表现为：京津冀〉珠三角〉长三角；区域内差异是区域总差异产生的主要原因；经济发展水平和能源效率对京津冀和长三角城市群环境效率有明显的促进作用；而产业结构对京津冀和珠三角城市群的环境效率有一定的抑制作用；外资依存度仅对珠三角城市群的环境效率有明显抑制作用；而环境治理能力的提高对三大城市群环境效率都有促进作用。
在環境約束趨緊的揹景下，選取京津冀、長三角和珠三角35箇城市2005—2012年的麵闆數據，運用SBM—Undesirable模型對環境效率進行測算，應用泰爾指數從區際層麵對環境效率差異進行衡量，併運用Tobit迴歸模型對環境效率的影響因素進行瞭研究。結果顯示，我國三大城市群環境效率平均值的區域分佈為：珠三角〉長三角〉京津冀；環境效率區域差異明顯，錶現為：京津冀〉珠三角〉長三角；區域內差異是區域總差異產生的主要原因；經濟髮展水平和能源效率對京津冀和長三角城市群環境效率有明顯的促進作用；而產業結構對京津冀和珠三角城市群的環境效率有一定的抑製作用；外資依存度僅對珠三角城市群的環境效率有明顯抑製作用；而環境治理能力的提高對三大城市群環境效率都有促進作用。

This essay selects the panel data of 35 cities from 2005 to 2012 in Beijing -Tianjin - Hebei Region, the Yangtze River Delta and the Pearl River Delta Areas. Using SBM - Undesirable model, it calculates environmental efficiency, and applying Theil index it measures environmental efficiency difference in the interregional level. And by using Tobit regression model it studies the influential factors of environmental efficiency. The results show that the average efficiency of the Pearl River Delta Area is the highest of all, followed by the Yangtze River Delta Area, Beijing - Tianjin - Hebei Region is the lowest. Regional differences are obvious. The difference of Beijing - Tian- jin - Hebei Region is the biggest of all, followed by the Pearl River Delta Area, and the Yangtze River Delta Area is the smallest. The internal difference of regional efficiency is the main reason that causes the total difference ; In the Beijing - Tianjin - Hebei Region and the Yangtze River Delta Area, the level of economic development and energy efficiency plays positive effect in promoting efficiency; but industrial structure plays negative effect in the Beijing - Tianjin - Hebei Region and the Pearl River Delta Area; Foreign dependency has obvious inhibitory effect on economic growth efficiency only in the Pearl River Delta Area. The improvement of environmental governance capacity playspositive effect in three areas.
