摘　　要：耕地细碎化会导致农户种植活动的分散化,减少了农户的有效劳动时间,并阻碍了机械化作业的开展,不利于种植业的增产增收。采用“全国农村固定观察点调查”2009—2020年的面板数据,以种植主导型农户为研究样本,分析发现:农户的耕地细碎化程度提高对其种植业收入具有显著的负向影响,该结论在经过一系列稳健性检验和内生性处理后依然成立;家庭种植结构“非粮化”和村庄耕地流转率提高可以显著弱化耕地细碎化对农户种植业收入增长的抑制作用;相对而言,耕地细碎化对化肥施用强度较高农户、老龄化程度较高农户、丘陵山区农户的种植业收入具有更强的负向影响。因此,应促进耕地流转市场发育,加强农村土地整治,提高粮食生产比较收益,推动化肥农药使用减量增效,拓展优化农业社会化服务,在降低农户耕地细碎化程度的同时,有效缓解耕地细碎化对农民收入增长的抑制作用。Promoting moderate-scale management of land has been the only way for China's agricultural modernization,and promoting the continuous increase of farmers' income has been an objective requirement for achieving common prosperity.In July 2023,the Ministry of Agriculture and Rural Affairs issued the Guiding Opinions on Safely Carrying out Pilot Work on Solving the Fragmentation of Contracted Land,which emphasized exploring solutions to cultivated land fragmentation while focusing on the relationship between farmers and land.The Central Rural Work Conference of the same year stressed,“to build a strong nation,we must first strengthen agriculture;only when agriculture is strong can the nation be strong”.Currently,China is in a transitional period from traditional agriculture to modern agriculture,and the planting industry remains the primary livelihood for most farmers.As the backbone of ensuring national food security and promoting rural revitalization,promoting sustained income growth for planting-dominant farm households is an objective requirement for solidly advancing common prosperity.Therefore,in this context,studying the specific impact of cultivated land fragmentation on the income of planting-dominant farmers has become a hot topic for discussion.To this end,this paper constructs an analytical framework and empirically tests the impact of cultivated land fragmentation on the income of planting-oriented farmers based on 12 rounds of panel data from the National Rural Fixed Observation Points from 2009 to 2020.The research findings are as follows:(1) Cultivated land fragmentation significantly reduces the income of farm households engaged in planting.This conclusion still holds even after a series of robustness tests.(2) The results of the moderation effects test show that the “non-grain production” of crop planting and the development of farmland transfer markets can significantly weaken the inhibitory effect of cultivated land fragmentation on the income of farm households engaged in planting.(3) Het
