This study calculates the effect of different types of land circulation on farmers' decision-making regarding agricultural planting structure, using field survey data involving 1,120 households in Hubei province, China, and PSM (propensity score matching) and GPSM (general propensity score matching) methods. Results from PSM showed that land circulation could significantly increase farmers' decisions to plant food crops, which confirms the positive effect of rural land circulation on the "grain orientation" of crop planting structure. Results from GPSM further indicate that the total land circulation, the paddy land circulation, and the dry land circulation all have significantly positive effects on planting structure adjustment towards "grain orientation." Additionally, planting structure adjustment towards "grain orientation" increases as the scale of land circulation increases, and the former shows a higher rate of increase than the latter, which confirms that rural land circulation facilitates an adjustment in structure towards planting food crops.
本研究利用中国湖北省 1120 户农户的实地调查数据，采用倾向得分匹配（PSM）和广义倾向得分匹配（GPSM）方法，计算了不同类型土地流转对农户农业种植结构决策的影响。PSM 结果表明，土地流转可以显著增加农户种植粮食作物的决策，这证实了农村土地流转对种植结构“粮食化”的积极影响。GPSM 的结果进一步表明，全部土地流转、水田流转和旱地流转均对种植结构向“粮食化”调整具有显著的正向效应。此外，种植结构向“粮食化”调整随着土地流转规模的扩大而增加，且前者的增长率高于后者，这证实了农村土地流转有利于种植粮食作物的结构调整。
