摘　　要：高标准农田建设可将“粮田”变“良田”,是牢牢守住保障国家粮食安全底线的战略基点。本文在梳理高标准农田建设对耕地“趋粮化”影响效果的理论逻辑基础上,以高标准农田建设政策为准自然实验,采用连续型双重差分法,系统考察高标准农田建设政策对农地种粮决策的影响及其作用机制。研究表明:高标准农田建设政策显著提高了粮食播种面积占比,产生“趋粮化”效应,此结论在一系列稳健性检验后依然成立。动态效应分析发现,随着高标准农田建设的不断推进,其助推耕地“趋粮化”效应不断增强。异质性分析表明,高标准农田建设政策在平原、农业依赖度高及耕地面积大的地区的耕地“趋粮化”的促进效果更佳。机制分析表明,高标准农田建设政策借助土地规模化、服务规模化及技术进步渠道影响耕地“趋粮化”。进一步研究表明,合作社发展及涉农信贷投放能够强化高标准农田建设政策对耕地“趋粮化”的促进作用。The construction of high-standard cropland can improve the quality of arable land,which is a strategic base for guaranteeing national food security.Based on the quasi-natural experiment of the high-standard cropland construction policy,the effect of high-standard cropland construction policy on the decision-making of grain cultivation on farmland was examined by adopting the continuous difference-in-differences method.The result shows that the high-standard cropland construction policy significantly increases the the proportion of grain sown area and produces a“grain-oriented”effect.The conclusion still holds after a series of robustness tests.The dynamic effect analysis reveals that as the construction of high-standard cropland continues,its effect of promoting the“grain-oriented”effect on cropland continues to increase.Heterogeneity analysis shows that the high-standard cropland construction policy is more effective in promoting the“grain-oriented”cultivated land in plain areas,higher agricultural dependent areas,and larger cultivated land areas.Mechanism analysis indicates that the high-standard cropland construction policy influences the“grain-oriented”cultivated land by land scaling,service scaling and technological progress.Further research illustrates that the development of cooperatives and agricultural credit investment can strengthen the promotion effect of the high-standard cropland construction policy on the“grain-oriented”cultivation of arable land.
