借助IAD理论框架，将村庄特征分为物质属性、共同体属性、规则三个维度，基于CLDS2016数据，用熵权TOPSIS法对村级公共品整体供给水平、供给结构分别进行量化，运用有序probit模型实证检验村庄特征、民主治理对村级公共品供给的影响。研究发现：村内宗族异质性越低、平均受教育水平越高、人口规模越大、人均农业用地面积越多，越有利于村级公共品整体供给，也有利于村级非生产性公共品的供给；人口规模越大、村庄距离县城越远，越有利于村级生产性公共品的供给，行政村中自然村数量对村级生产性公共品的供给产生负向影响；民主治理更有利于村级非生产性公共品的供给，且在村内平均受教育水平、村庄人口规模影响公共品供给的过程中发挥中介效应。

With the help of the IAD theoretical framework, this article divides village characteristics into three dimensions: material attributes, community attributes, and rules. Based on CLDS2016 data, the entropy-weighted TOPSIS method was used to quantify the overall supply of rural public goods and the supply structure of rural public goods, respectively. The ordered probit model is used to empirically test the impact of village characteristics and democratic governance on the supply of rural public goods. The study found that: the lower the clan heterogeneity in the village, the higher the average level of education, the larger the population size, the more the per capita agricultural land area, the more beneficial to the overall supply of rural public goods, and the more favorable to the supply of rural non-productive public goods; The larger the population and the farther the village is from the county, the more favorable to the supply of productive public goods. The number of natural villages in administrative villages has a negative impact on the supply of productive public goods; Democratic governance is more conducive to the supply of non-productive public goods at the village level. Democratic governance plays an intermediary role in the process of the average education level of farmers and the size of village population affecting the supply of public goods.
