Abstract: Sociological institutionalism is a representative sociological path in the theories of European integration, aiming to describe and explain the impact of social behaviors, cultural contexts,and cognitive frameworks and norms on the evolution of the EU member states and its institutions. It also proposes some concepts from sociological perspectives, such as socialization, the logic of appropriateness and isomorphism. Sociological institutionalism shares many assumptions with social constructivism and has a unique explanatory advantage on the issue of identity. Nevertheless, the approach faces theoretical and practical challenges; we should thus strive to further elucidate the endogenous mechanisms by which institutions influence behaviors and measure the influence of cultural cognitive factors. Moreover, sociological institutionalism highlights the stability of institutional norms, whereas, to some extent, neglecting how the institutions have been shaped by social interactions, ie. the flexibility of institutions, thus exposing the limitations of sociological institutionalism in explaining institutional changes. In this regard, deeper reflection on the features and implications of sociological institutionalism provides important relevance for understanding the dynamics of European integration.

摘要： 社会学制度主义是欧洲一体化理论中具有代表性的社会学路径，旨在描述和解释社会行为、文化背景、认知框架和规范对欧盟成员国和欧洲组织机构演进的影响，并提出社会化、适当性逻辑、同构性等具有社会学意义的概念。它与社会建构主义共享许多假设，在认同问题上具有独特解释优势。当然，该理论也面临挑战，需要进一步阐明制度影响行为的内生性机制，并尝试衡量文化认知因素的影响程度；此外，它更突出制度规范的稳定性，而相对忽视了社会互动对制度的塑造和制度的灵活性，从而暴露出社会学制度主义在解释制度变迁上的限度。因此，深入思考社会学制度主义的内涵特征对理解当下欧洲一体化发展态势仍具重要参照意义。
