中国正处于深刻的社会转型和社会变迁时期，社会风险加剧。其中一个重要的表征就是群体性事件频发。事件的背后，反映出民众对公共政策的不认可，如果公共政策的制定和执行不能充分考虑民众的接受性，极有可能构成新的社会风险，威胁社会稳定。因此，如何有效地提高民众对公共政策的接受性已经成为我国亟需解决的重大问题。本研究欲实现的目标是：建立程序公正、结果宜人性和权威信任(认知信任和情感信任)对公共政策可接受性、政府满意度的影响模型，从而有效提升政策可接受性。本研究拟在不同的公共政策情境中通过Scenario、实验室模拟实验和问卷调查，探明程序公正和结果宜人性对政策可接受性、政府满意度的交互作用，以及认知信任和情感信任的中介作用；在信任信息已知情况下，进一步分析认知信任和情感信任对于政策可接受性、政府满意度及其因子关系的调节作用。本研究成果可用于提高民众对政策的满意度，为政府制定政策提供科学依据。

China is in a period of social transformation and social change, and social risk is increasing. One important characterization is that collective actions frequently occur. It hints that people do not accept public policy. If formulation and implementation of public policy does not fully consider public acceptability, it is likely to constitute a new social risk, threatening social stability. Therefore, how to effectively improve public acceptance of public policy has become a major problem that should be solved in our country. The objectives of this study are to establish a model of acceptance of public policy and satisfaction with government with the impact of procedural justice, outcome favorability and trust in authority (cognitive trust and affective trust) and to effectively enhance the acceptance of the policy. Through scenario, experiment, and cross-sectional survey, this study tries to investigate the interaction between procedural justice and outcome favorability on acceptance of public policy and satisfaction with government, and the mediation of cognitive trust and affective trust; in the case of known trust, to further analyze the moderation of cognitive trust and affective trust on the relationship between acceptance of policy, satisfaction with government and their factors. The results can be used to improve public satisfaction with the policy, and to provide a scientific basis for government policy.
