农地产权制度是影响农村耕地资源利用方式和效率的重要影响因素,不同阶段的农地流转制度作为农地产权制度的重要组成部分也将通过影响农户行为最终对耕地生态环境产生影响。从理论上阐述中国农地流转制度变迁对耕地生态环境变化的影响机理,并选取相关指标利用1978-2013年全国数据建立模型对其进行了检验,结论证实两点:一与农地流转禁止阶段相比,被允许进行土地流转的阶段对耕地生态环境有显著的负面效应;二农地流转制度越完善,流转方式越规范,流转市场越成熟对耕地生态环境保护越有利。
The system of farmland property right is an important factor that affects the utilization mode and efficiency of farmland resources in rural areas. As an important part of farmland property right system, farmland transfer system in different stages will also influence farmland ecological environment finally by affecting farmers’ behavior. This paper elaborates the mechanism of the change of farmland circulation system in China on the change of cultivated land eco-environment in theory and selects the relevant indicators to test the model using the national data from 1978 to 2013. The conclusion confirms two points: Compared with the farmland, the stage of land transfer allowed to have a significant negative effect on cultivated land ecological environment. The more perfect the system of farmland conversion, the more standardized the mode of circulation and the more mature the circulation market are, the better the protection of cultivated land ecological environment.
