摘　　要：耕地“非粮化”整治对国家粮食安全具有重要意义。利用“中国乡村振兴调查(CRRS)”数据系统探讨耕地细碎化对农户种植结构的影响以及农户数字参与在这一关系中的调节效应。研究表明:从总体估计来看,耕地细碎化对种植结构“非粮化”具有显著的正向影响,耕地细碎化越严重,农户种植结构“非粮化”程度越高;从东中西部地区的分样本估计来看,耕地细碎化对种植结构“非粮化”的影响在中部和西部地区仍较为稳健,但在东部地区影响不显著;从平原、丘陵和山区地形的分样本估计来看,在平原和丘陵地区,耕地细碎化会推动农户种植结构“非粮化”,但这一影响在山区并不显著;从农户不同经营规模分样本估计来看,对于经营规模在5亩以上的农户,耕地细碎化会对农户种植结构“非粮化”具有显著的正向影响,但对于经营规模在5亩以下的农户,这一影响并不显著;农户数字参与将加剧其种植结构“非粮化”趋势,且在耕地细碎化对种植结构“非粮化”的影响机制中具有调节效应。据此,政府在遏制“非粮化”过程中,应合理开展耕地细碎化整治,防范数字化演进所引致的种植结构“非粮化”倾向。The remediation of farmland“non-gratification”is of great significance for national food security.This article utilizes data from the China Rural Revitalization Survey(CRRS)to explore the impact of farmland fragmentation on farmers’planting structure and the moderating effect of farmers’digital participation in this relationship.Research has shown that,overall,farmland fragmentation has a significant positive impact on the“non-grainization”planting structures;the more severe the fragmentation,the higher the degree of“nongrainization”in farmers’planting structure of farmers.When analyzing subsamples from the eastern,central,and western regions,the impact of farmland fragmentation on“nongrainization”remains robust in the central and western regions,but is not significant in the eastern regions.From the perspective of different terrains——plains,hills and mountainous areas——farmland fragmentation promotes“non-grainization”in the plains and hilly regions,while this effect is not significant in mountainous areas.Regarding different operational scales of farmers,for those managing more than 5 acres,farmland fragmentation has a significant positive impact on“non-grainization”planting structure of farmers;however,this effect is not significant for those managing less than 5 acres.Furthermore,farmers’digital participation exacerbates the trend of“non-grainization”in their planting structure,and plays a moderating effect in the mechanism through which farmland fragmentation affects“non-grainization”.Therefore,in the process of curbing“non-gratification”,the government should reasonably guide farmland fragmentation and guard against the trend of“non-gratification”in planting structures caused by digitization.
