政治认同问题是政治学领域的一个重要问题，也是改革开放30多年后的今天中国社会在转型时期面临的重大课题。什么是政治认同？政治认同的构建动因是什么？如何对政治认同进行主动构建？这种构建是否可能，又在何种意义上有效？这些便是本研究试图解决的主要问题。 论文第一章是对认同和政治认同的基本概念进行了综述性质的界定。第二章重点提出了对政治认同构建动因的基本假设——即利益、制度、和价值观是构建政治认同的三个基本层面。只有在这三个基本层面上满足认同主体的需求，才能保证其对政治共同体产生稳定的政治认同。此外，本文还提出了不同政治共同体间的政治认同具有相互竞争性。当一种政治共同体所提供的利益、制度和价值观不能满足认同主体的需求时，认同主体的政治认同便可能改变。故对当前国际格局而言，民族国家虽然因为历史社会因素而成为占据主流地位的政治认同对象，但这一地位并非不可动摇的。而欧盟对其政治认同的构建则为这一论点提供了一个最优案例。因此，论文第三章从欧盟对内构建政治认同的机制出发，对欧盟在利益、制度、和价值观的层面满足其公民需求的情况进行定性分析。第四章采用欧洲晴雨表(EuroBarometer)的有关数据对第三章的定性分析作了相关定量研究。同时，本文还提出，欧盟的政治认同不仅是一个内部构建过程，还是一个向外扩张的过程。鉴于此，本文在第五章研究了欧盟通过对外非军事行动以实现其规范性力量的过程，并以欧盟在刚果（金）的安全部门改革为具体案例进行分析，以得出欧盟对外扩张其政治认同的过程、效用及利弊得失。并进一步分析了对外非军事行动对欧盟政治认同的影响。文章结论部分提到政治认同构建理论的意义及对中国的启示。

The issue about Political identity is one of the most important issues in politics, which is also the one of the most essential topics that China encounters during its transition period 30 years after the Open-door policy. What is political identity; what is its construction motivations; how to build a political identity; on what extent this building is possible and effective—these are the main questions this thesis is going to resolve.The first chapter of this thesis is to define the “identity” and “political identity” in a comprehensive approach. The second chapter initiates the main hypothesis that there are three levels to construct a political identity, namely interest’s level, institute’s level, and the value’s level. Only if all of the three levels are satisfied, will a political identity be stable and sustainable. Moreover, the political identities are competitive to each other. When a politic community satisfies the identity subjects more on the above three levels than other communities, the subjects’ political identity may shift more to this community rather than to others. Therefore, though nation states are the main communities that have the most stable political identities nowadays ascribing to the historic social elements, this situation would be changed in future. The way that the EU constructs its subjects’ political identities is a case here. Accordingly, the third and forth chapters are exploring the approaches that the EU constructs the political identity among its member states’ citizens qualitatively and quantitatively respectively. Moreover, this research considers the EU political identity construction is not only an inward process, but also an outward expanding. Therefore, the fifth chapter studies the process that the EU realizes its normative power via non-military operations abroad, with a case study on EU’s SSR in DRC, to analysis the process, effect, and lessons of the EU’s expanding of its political identity.
