过度消耗生态资本的传统经济模式。在成就中国经济增长奇迹的同时，也造成了生态资本存量的短缺，生态资本投资因而成为经济绿色转型研究的热点问题。生态资本效率提升是生态资本投资的重要目标，通过引入SBM模型处理非合意产出，测算了2003—2010年我国各省份的生态资本效率。结果显示．生态资本效率的省际差异较为明显；从各年的生态资本效率平均值来看，三大区域生态资本效率自东向西梯度递减。为考察生态资本投资对生态资本效率的影响，使用Tobit回归对各省份环境污染治理投资、当年造林面积、自然保护区面积等变量进行了检验。结果表明。东部地区的生态资本投资对于生态资本效率提升具有促进作用．而中西部地区生态资本投资的作用并不显著。应当认识到生态资本投资方式对于促进经济绿色转型的层次差异性，进而实施差异化的区域生态资本投资战略。
過度消耗生態資本的傳統經濟模式。在成就中國經濟增長奇跡的同時，也造成瞭生態資本存量的短缺，生態資本投資因而成為經濟綠色轉型研究的熱點問題。生態資本效率提升是生態資本投資的重要目標，通過引入SBM模型處理非閤意產齣，測算瞭2003—2010年我國各省份的生態資本效率。結果顯示．生態資本效率的省際差異較為明顯；從各年的生態資本效率平均值來看，三大區域生態資本效率自東嚮西梯度遞減。為攷察生態資本投資對生態資本效率的影響，使用Tobit迴歸對各省份環境汙染治理投資、噹年造林麵積、自然保護區麵積等變量進行瞭檢驗。結果錶明。東部地區的生態資本投資對于生態資本效率提升具有促進作用．而中西部地區生態資本投資的作用併不顯著。應噹認識到生態資本投資方式對于促進經濟綠色轉型的層次差異性，進而實施差異化的區域生態資本投資戰略。

The traditional economy mode depending on the excessive consumption of ecological capital, has acquired the achievements of Chinese economic growth miracle, and it caused the shortage of ecological capital at the same time. Ecological capital investment has become the hot issue in the study of economic green transformation. To improve the ecological capital efficiency is an important target of ecological capital investment. Through processing the non-consensual output by SBM model, the paper calculated each province＇ s ecological capital efficiency from year 2003 to year 2010 in China. The results showed the difference of each province＇ s ecological capital efficiency is obvious. Seen from the average efficiency, the three regions＇ ecological capital efficiency was diminishing from east China to west China. In order to study the influence of ecological capital investment to ecological capital efficiency, some variables such as the investment in treatment of environmental pollution, the area of forestation and the natural protection area were tested by Tobit regression method. The results showed that, the effect of ecological capital investment to promote ecological capital efficiency was significant in the eastern region; however it was not significant in the central and western areas. We should recognize the effect difference of the ecological capital investment to promoting economic green transformation, and then adopt the discrepant strategy in regional ecological capital investment.
