基于黑龙江省478份玉米种植户的调查数据，实证分析不同邻里社会网络对小农户保护性耕作技术采纳的边际效应和传导路径。结果表明，邻里社会网络影响的边际效应顺次为周围小农户>专业大户>宗亲网络。周围小农户主要通过示范机制、社会规范与环境责任认知促使小农户采纳保护性耕作技术，以专业大户为代表的邻里社会网络主要通过示范机制和社会规范提高小农户采纳保护性耕作技术水平，宗亲网络主要通过环境责任认知提高小农户保护性耕作技术采纳概率。

Based on the micro-survey data of 478 farmers’cultivated land utilization in Heilongjiang Province, Empirical analysed the marginal effect and transmission path of different neighborhood social networks on the adoption of conservation tillage technology by small farmers. The results showed that surrounding small farmers > professional large households > clan network. Surrounding smallholders mainly promote smallholders to adopt conservation tillage technology through demonstration mechanisms, social norms and awareness of environmental responsibility; neighborhood social networks represented by large professional households mainly improve the level of smallholders to adopt conservation tillage technology through demonstration mechanisms and social norms; clan networks mainly improve the adoption probability of conservation tillage technology by smallholders through awareness of environmental responsibility.
