生态建设项目的公共价值绩效及其内部结构——以河北省赤城县为例

从公共价值角度，构建了生态建设过程与生态效果相结合的生态建设项目绩效评价指标体系，定量评价已经实施了的生态建设项目公共价值绩效：退耕还林和首水工程的评价值分别为0．9013、0．8754，实施效果很好；小流域治理工程的评价值为0．7161，实施效果较好；全面禁牧工程的评价值为0．1538，效果很差。从这4种生态建设项目绩效的内部结构来看，过程绩效都小于终端绩效。其中，全面禁牧工程的过程绩效只是终端绩效的12．90％。过程绩效和终端绩效的显著差异，反映了生态项目集中关注生态效果，而忽视实施过程的普遍问题。生态建设项目的公共价值绩效评价，将为生态建设项目评价提供一种新的方法，为政府绩效治理提供一个新的案例。

Public Value Performance and Internal Structure of Ecological Construction Projects--Taking Chicheng County of Hebei Province as an Example

This paper builds a performance evaluation index system of ecological construction project which combines the process of ecological construction and ecological effect from the public value angel and quantitatively measures the performance of implemented ecological projects： Returning farmland to forest and water conservation project of capital have good effects with public value performance evaluation scores of 0.9013 and 0.8754; Small watershed management project has better effect with a performance evaluation score of 0.7161 and comprehensive grazing prohibition project has the poorest effect with a performance evaluation score of 0.1538 We can see from the internal structure of the performances of four ecological construction projects that the process performances are less than the terminal ones and the process performance is just 12.90% of the terminal performance respectively in comprehensive grazing prohibition project. The notable difference in process and terminal performances reveals the general problem that current ecological project focuses on the ecological effects and ignores the process of policy implementation. The public value performance evaluation of ecological construction project will provide a new way for the evaluation on construction projects and a new case for the performance management of the government.
