农村集体产权制度改革是乡村振兴战略的重要制度供给，对壮大集体经济、提升村庄公共品自给能力具有重要意义。基于2012—2018年山东、河北、河南、吉林、福建、陕西、云南、新疆8省（区）171个行政村的非平衡面板数据，综合运用多期双重差分模型和中介效应模型，分析了集体产权制度改革对村庄公共品自给能力的影响及作用机制。研究发现，集体产权制度改革对村庄公共品自给率的提升具有显著促进作用，能够有效提升村庄公共品自给能力；改革的政策效应存在公共品品类异质性，对非生产性公共品自给率的促进作用强于生产性公共品；村集体经营性收入在其中发挥了部分中介作用。

The reform of the rural collective property rights system is an important institutional supply for the rural revitalization strategy, and is of great significance in promoting the development and growth of the collective economy and enhancing the self-sufficiency of village public goods. Based on the unbalanced panel data of eight provinces and 171 administrative villages from 2012 to 2018, this paper evaluates the impact of collective property rights system reform on the self-sufficiency of public goods in villages and the mechanism by using multi-period difference-in-differences model and a mediating effects model. The results show that the reform of the collective property rights system has a significant contribution to the self-sufficiency rate of village public goods. The policy effect of the reform is heterogeneous in terms of public goods categories, which is embodied in the promotion effect of self-sufficiency rate of non-productive public goods is stronger than that of productive public goods. The village collective operating income plays a partial mediating role in the reform's impact on the self-sufficiency of village public goods.
