Abstract:  Perfecting major policy social stability risk assessment mechanism is an important link in modernizing state governance and the governance system. The multisubject assessment model involves three parties, namely, the government, the interestrelated party, and the third party. It is the choice for major policy social stability risk assessment because it can strengthen the subjects’ independence and ensure democracy of the process and reliability of the result. However, to establish a multisubject assessment model for major policy social stability risk assessment, we have to first confront a number of challenges, including the autistic tendency of the government, the lack of awareness in stability risk assessment among other parties, incapacity of the parties to conduct the assessment, and the absence of system guarantee. The multisubject assessment model can be more effectively developed through reshaping the conception of government governance, strengthening the consciousness of assessment among the other subjects, improving the assessment competence of various parties, and perfecting the system of assessment.
