中国社会信用体系建设是在我国宪法制度框架下，政府、立法、司法、私主体共同参与和构建的一种新型国家治理模式。虽然这种模式还在发展、仍未定型，但是由于其创新了国家治理方式、事关公民数据权利，应当被承认为是一种宪制性制度安排，并从宪制的视角进行研究和分析。以中国社会信用体系建设的参与主体为区分，政府、立法、司法、私主体都发挥了国家治理的功能，进而影响公民基本权利的保障，但这些主体的参与策略不同。从个人信用信息保护的宪法规范基础来说，现行宪法上基本权利条款的规范解释，已经足以为个人信息处理场景下的基本权利提供规范依据与理论基础。个人信息处理中涉及的宪法基本权利的具体场景，表现为平等权、政治权利、自身自由、社会经济权利等等基本权利的“信息化”。从政府角度来说，社会信用体系建设部际联席会议制度是中央政府主导社会信用体系建设所采用的主要制度，在中央政府层面统筹社会信用体系的设计、推动和实施，具有政务诚信建设功能、内部沟通协调功能、外部信用监管功能。从立法角度来说，在国家层面社会信用立法缺位的情况下，我国社会信用地方立法构成一种竞争性模仿模式；其竞争性表现在社会信用地方立法之间形式与内容的趋同，也表现在其对上位法规范的引入，导致各地社会信用地方立法形式与内容上均存在一定的同质性。从司法角度来说，法院的角色不只是信用惩戒执行环节的执行者，对社会信用体系建设不是排斥的，而是采取自发地共谋、积极地吸纳的策略；法院参与也是有限度的，受到依法裁判和宪制空间的限制，因而采取适度地变形、合法地解释的策略。从私主体角度来说，以“芝麻信用”为代表的私主体既是社会信用体系建设中的被监管者，又是主动参与社会信用体系建设的参与者，还是对个人用户行使治理功能、具有公权力性质的治理者。中国社会信用体系建设作为一种宪制实践，因其治理功能而嵌入宪制框架，又因其新型模式而超越宪法条文，为宪法规范提供了发展空间。它作为国家宪制的规范性，体现在宪制框架下政府、立法、司法、私主体一致主动、具有实效的参与，这些主体的参与承认了中国社会信用体系建设是中国宪制的实践构成。

The China’s Social Credit System(CSCS) is a new model of national governance under the framework of Chinese constitutional system, in which governmental, legislative, judicial, and private subjects participate. Although this model is still developing and not yet finalized, it should be recognized as a constitutional practice and studied from a perspective of effective constitution, as it is an innovation of national governance and concerns the data rights of citizens.The participating subjects in the CSCS, including governmental, legislative, judicial, and private subjects, function in national governance, which in turn affects the protection of civil rights of citizens; these above-mentioned subjects, however, have different participation strategies. In terms of the normative basis of personal credit information protection, the interpretation of the civil rights provisions under the Chinese Constitution is sufficient to provide the normative basis and theoretical foundation in the personal information processing scenario. The specific scenarios of civil rights involved in personal information processing could be described as the “informatized” civil rights such as the equality right, political rights, personal freedom and social and economic rights.From the government’s point of view, the system of inter-ministerial joint meeting for the CSCS is the main system adopted by the central government to lead the construction of the CSCS, which coordinates the design, promotion and implementation of the CSCS, and has the functions of governmental credit building, internal communication and coordination, and external credit regulation.From the legislator’s point of view, in the absence of the national social credit legislation, local social credit legislation reflects a competitive imitation model; its competition is manifested in the convergence of form and content among local social credit laws, as well as in its introduction of the rules of higher laws and regulations, leading to a certain degree of homogeneity in the form and content of local social credit legislation.From the judiciary point of view, the courts is not only the executor of the credit discipline, but also adopt strategies of spontaneous complicity and active inclusion. The courts’ participation were also limited by the space to adjudicate according to the legal system, thus adopting strategies of moderate deformation and legal interpretation.From the perspective of private entities represented by “Sesame Credit”, they are not only the regulated, but also the participants who actively participate in the construction of the CSCS, as well as the regulators who administrate individual users and have the nature of public power.As a constitutional practice, the CSCS is not only embedded in the constitutional framework because of its governance function, but also transcends the Chinese Constitution text because of its innovation. It therefore provides space for the development of effective constitution. Its normativity is reflected in the active and effective participation of governmental, legislative, judicial and private subjects under the constitutional framework, and the participation of these subjects recognizes the CSCS as a practical constitution of Chinese constitutional system.
