Abstract: China's gender imbalance has lasted for 40 years, and has become a major issue limiting the sustainable development of population and society. The increasingly significant risks arising from gender imbalance intertwined with social benefit differentiation pose challenges to the governance of gender imbalance. In the context of risk society, demands for greater public participation have emerged in policy circles. This study theoretically extends previous research on the causal mechanism of public participation and highlights useful policy implications. Building on the O-S-OR framework, the current study proposes a conceptual model to investigate whether and how trusted information acquisition influences public participation through trust and risk perception. Using data from the Social Risks and Governance of Gender Imbalance Survey conducted in 2018, and exploiting structural equation modelling, the paper finds that information acquisition is positively associated with public participation. This study also finds that the effect of information acquisition on public participation is partially mediated by government trust and risk perception of gender imbalance.

摘要： 中国的性别结构失衡已持续40多年，成为制约人口与社会可持续发展的重大问题。长期累积的人口风险与社会利益的高度分化相互交织，对现有治理模式提出了严峻挑战，新常态下亟须创新和完善性别失衡治理机制，公众参与是关键突破点。从信息获取出发，深入探究其通过信任和风险感知对公众参与的影响机制，不仅从理论层面上揭示了促进公众参与的内在机理，还为推进基层治理共建共治共享提供了有价值的政策启示。基于O-S-O-R模型，建构风险社会背景下性别失衡治理中公众参与的研究框架，采用结构方程模型，对2018年开展的“性别失衡的社会风险及治理”专项调查数据进行实证分析。研究发现，信息获取对公众参与具有显著正向影响，政府信任和风险感知在这一关系中均发挥了部分中介作用。
