Will land circulation sway "grain orientation"? The impact of rural land circulation on farmers' agricultural planting structures

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.
