摘　　要：粮食安全是建设农业强国的根基,探究粮食产业高质量发展水平的区域差异及收敛特征是建设农业现代化强国的应有之义。论文以武陵山区66个县域为研究对象,利用DEA-Malmquist指数法测度2013—2021年粮食产业全要素生产率,运用变异系数、Dagum基尼系数及其分解以及β收敛模型研究武陵山区县域粮食产业高质量发展的区域差异、影响因素及收敛特征。研究发现:武陵山区粮食产业全要素生产率处于波动上升趋势,技术效率是粮食全要素生产率增长的主要源泉,空间分布呈现出“南北两头热中部冷”的格局。武陵山区粮食产业高质量发展水平的基尼系数总体呈下降趋势,区域内差异是造成总体差异的主要原因。产业结构高级化、农业服务对粮食产业高质量发展水平增长率具有显著的正向效应,而数字普惠金融具有显著的负向效应。数字普惠金融、产业结构高级化、农业服务对粮食产业高质量发展水平增长率具有显著的区域异质性特征。武陵山区粮食产业高质量发展存在σ收敛、绝对β收敛及条件β收敛。建议加强科技创新,实现技术效率与技术进步“双轮驱动”;充分利用区位优势,发展武陵山区特色生态农业;优化粮食产业结构,实现一二三产业融合发展;缩小区域发展差异,化解武陵山区粮食产业发展不均衡问题。Grain security is the cornerstone of establishing a powerful agricultural nation.Exploring the regional disparities and convergence characteristics in the high-quality development of the grain industry is a necessary endeavor in building a modernized and robust agricultural nation.Based on the study of 66 counties in Wuling mountain area and applying the DEA-Malmquist index method,this paper seeks to measure the total factor productivity of the grain industry from 2013 to 2021 and to explore the regional differences,influencing factors,and convergence characteristics of the high-quality development of the grain industry in Wuling mountain area by the coefficient of variation,the Dagum Gini coefficient and its decomposition,and theβ-convergence models.Results show that the total factor productivity of the grain industry in Wuling mountain area is showing a fluctuating upward trend,the technical efficiency is the main source of growth in total factor productivity of grain production,and the spatial distribution exhibits a pattern of"warm in the north and south,but cold in the central region".The Gini coefficient of the high-quality development level of the grain industry in Wuling mountain area is generally declining,with regional disparities being the primary cause of the overall difference.Industrial structural upgrading and agricultural services have significantly positive impacts on the growth rate of the high-quality development level of the grain industry,while inclusive digital finance has a noticeably negative effect.In addition,inclusive digital finance,upgrading of industrial structure,and agricultural services exhibit significant regional heterogeneity in their impacts on the growth rate of the high-quality development level of the grain industry.There isσconvergence,absoluteβ-convergence,and conditionalβ-convergence in the high-quality development of the grain industry in Wuling mountain area.Therefore,based on the above findings,this paper suggests:strengthening technological innovation to achieve
