本文采用文献研究和因子分析法建立评价指标体系，选取我国生态治理中具有代表性的区域——陕西省，运用DEA-Malmqusit方法测算了2004至2014年间生态经济治理优化决策效率。采用output-SBM模型对2014年我国31个省份的生态经济治理优化决策效率进行测算。结果表明，陕西省的生态经济治理优化决策效率呈下降趋势；中、西部省份生态经济治理优化决策效率整体不及东部省份的效率值；东部省份在森林蓄积量和保护区面积占辖区面积比重两个产出指标存在产出不足现象，中、西部省份在人均水资源量和工业废水排放量两个产出指标存在产出不足现象。

This paper used factor analysis method to establish the evaluation index system. We selected Shaanxi as the representative area in China, and used DEA-Malmqusit method to evaluate its governance and optimization efficiency of regional ecology economy system from 2004 to 2014. The output-SBM model was used to estimate the efficiency value for 31 provinces in China. The results show that the efficiency of the governance and optimization efficiency of regional ecology economy system in Shaanxi is declining. The efficiency values in Central and Western Province are much less than Eastern Province. For Eastern Province, forest volume and the proportion of a protected area output shortfall, while per capita water resource and industrial wastewater discharge output shortfall for Central and Western Province.
