摘　　要：从狭义的农户兼业化出发,基于农业生产要素投入变化的视角就农户兼业化对农村生态环境的影响机理进行了系统梳理,并通过以2000—2016年我国30个省级行政单位数据建立的动态面板数据模型进行了实证分析。结果表明:农户兼业化对农村生态环境具有显著的负面影响,这种影响既有直接的,也有间接的;农户兼业化对农村生态环境影响的直接效应显著为负;在农户兼业化对农村生态环境的间接影响中,土地要素投入的中介效应并不显著,农户兼业化对农村生态环境的间接影响主要通过资本要素投入的中介效应表现出来;最后,农村生态环境变化在时间上具有明显的延续性,当前对我国农村生态环境的治理刻不容缓。Based on the corresponding relative definition,the study explores the mechanism of the impact of part-time farming of peasant household on the rural eco-environment systematically from the perspective of agricultural production factor inputs.The empirical analysis is conducted with the panel data of 30 provincial administrative units in China from 2000 to 2016.The conclusions are as follows:Firstly,part-time farming has negative effects on rural eco-environment directly and indirectly.Secondly,the direct impact of part-time farming on rural eco-environment is significantly negative.Thirdly,among all these indirect influence,the mediated effect of land factor input is not significant,which is mainly presented through the mediated effect of capital factor input.Finally,the change of rural eco-environment has reflected obvious continuity in time;improving rural eco-environment in China becomes a pressing task.
