Heterogeneity analysis.

The reform of rural collective property rights system is of great significance for protecting the collective asset rights and interests of villagers, activating rural resource elements, and achieving rural revitalization. This study is based on 284 village committee questionnaires and 7451 villager questionnaires from 10 provinces in China, and uses multi-layer linear regression models to explore the impact of the reform of rural collective property rights system on villagers’ public participation. Research has found that:(1) the reform of rural collective property rights system that has been completed at the rural level can significantly enhance the public participation of villagers, including total participation (β = 0.102, p ≤ 0.1), interest expression (β = 0.044, p ≤ 0.1), and election voting (β = 0.076, p ≤ 0.05). However, the impact on volunteer service is not significant (β = -0.004, p>0.1); (2)mechanism analysis shows that the reform can reduce the probability of migration for work, and thus enhance the level of public participation; (3)heterogeneity analysis reveals that the reform has a greater impact on the villagers’ public participation in suburban villages and villages with better collective economy; (4)further analysis discovers that villagers have heard that reform can significantly enhance their public participation. This study comprehensively explores the spillover effects of the reform at the village level on public participation at the individual level through the use of more accurate measurement indicators, empirical analysis methods, and large-scale authoritative data, providing strong support for proposing strategies to promote villages’ public participation.

农村集体产权制度改革对于保障村民集体资产权益、激活农村资源要素以及实现乡村振兴具有重要意义。本研究基于中国10个省份的284份村委会问卷与7451份村民问卷，采用多层线性回归模型，探究农村集体产权制度改革对村民公共参与的影响效应。研究发现：(1) 已在农村层面完成的农村集体产权制度改革可显著提升村民公共参与水平，涵盖总参与度（β=0.102，p≤0.1）、利益表达（β=0.044，p≤0.1）与选举投票（β=0.076，p≤0.05），但该改革对志愿服务参与的影响并不显著（β=-0.004，p>0.1）；(2) 机制分析表明，农村集体产权制度改革可降低村民外出务工迁移概率，进而提升其公共参与水平；(3) 异质性分析显示，该改革对城郊村及集体经济发展较好村庄的村民公共参与影响更为显著；(4) 进一步分析发现，知晓改革政策的村民公共参与水平会得到显著提升。本研究通过采用更为精准的测度指标、实证分析方法与大规模权威调研数据，全面探究了村级层面集体产权改革对个体层面公共参与的溢出效应，为提出促进村民公共参与的策略提供了坚实支撑。
