Finally, using this analysis framework and unifying the practice of the reform of institutions and public finance system, this paper preliminarily analyzes the overall way of constructing our country's non-profit organization system This paper makes conclusions as follow:1~, it is necessary to carry on the trichotomy to the field of resources disposition from the point of the supply-demand relation configuration because of the limitations to Bipolar Paradigm between market and government.2~, introducing the market mechanism to the domain of public service is helpful to improve economic efficiency of the supplies, but the lack of the corresponding ethics value standard and the government structure will cause the erosion of public welfare and the loss of commonality and fairness.3~, the sources of the fault to the reform of institutions are the vacancy of public ethics goal and the lag of public service fundamental research, which makes the reform of institutions follow the way of the reform of enterprise.

在完成公共服务分析框架后，作为本论文研究体系的延伸，在本文的最后部分，运用这一分析框架，结合我国事业单位改革和非营利组织发展的实践与公共财政体制改革，初步分析了构建我国公共事业体制框架的总体思路。通过公共服务分析框架的构建，本文得出的基本结论有以下几点：1、市场和政府二分的范式对认识公共服务和公共事业领域的资源配置存在局限性，因此有必要从供求关系构型上对资源配置场域进行三分法的划分。2、简单地在公共服务领域引入市场机制有助于供给者的经济效率提高，但是，如没有相应的伦理价值理念的规范和治理结构，必然会导致对公益消费者公共福利的侵蚀，出现公共性与公正性的流失。3、以推向市场和创收为实质内涵的我国事业单位改革失误的根源，在于公共伦理目标的缺失和对公共服务理论研究的滞后，因而才沿袭了企业改革的思维和方法。
