The sense of gain in anti-corruption work is an important indicator to measure the effectiveness of anti-corruption work, and has an important impact on the "credibility" of the government. Related issues have become the research focus of related disciplines such as politics and administration, but the existing research does not pay enough attention to the differential impact of the internal and external structural characteristics of social public individuals. In view of this, the paper studies the mechanism of its impact on the sense of gain in anti-corruption work from the dual perspectives of public external political participation and internal socio-economic status. Based on the comprehensive survey data of China's social situation, it is found that there is a significant positive correlation between the public's socio-economic status and their sense of gain in anti-corruption work; People's institutional political participation has a significant positive impact on people's sense of gain in anti-corruption work, and plays an incomplete intermediary effect in the process of people's socio-economic status affecting their sense of anti-corruption acquisition; Non institutional political participation can inhibit  people's sense of gain in anti-corruption work. Therefore, in order to further enhance the people's sense of access to anti-corruption, it is urgent to innovate and improve the people's political participation system, dredge group behavior actively; Meanwhile, strengthen grass-roots corruption governance, and strive to improve people's sense of gain in anti-corruption work.

民众反腐获得感是衡量反腐败工作效能的重要指标,更是对政府 “公信力”起到重要影响。相关问题已成为政治学和行政学等相关学科的研究重点,但鲜有研究探讨民众个体内部和外部结构性特征对其反腐获得感的影响作用。鉴于此,本文从民众内部社会经济地位与外部政治参与的综合视角出发,探究其对民众反腐获得感的作用机理。结合中国社会状况综合调查数据进行实证分析后发现:民众的社会经济状况与其反腐获得感之间具有显著正向相关性;民众制度性政治参与行为对民众反腐获得感产生显著的正向影响,并在民众社会经济地位影响其反腐获得感过程中起到不完全中介效应;而非制度性政治参与则会削弱民众反腐获得感状况。基于此,为进一步提升民众的反腐获得感,亟须创新完善民众参与途径和方式,积极疏导群体性行为;并着力加大腐败治理力度,深入治理民生领域的腐败问题,全面提升民众的反腐获得感。
