摘要: 发展农业社会化服务是农业现代化建设的重要内容,在粮食与生态“双安全”的格局下,探究其对粮食生态效率的贡献,对实现农业可持续发展具有重要意义。研究采用2011—2020年黄河流域71个地级市的面板数据,聚焦农业社会化服务对粮食生态效率的空间溢出及非线性效应。结果表明:(1)研究期内,黄河流域城市群粮食生态效率呈明显的改善趋势;空间上,呈现非均衡交错的分布格局,效率优良及以上等级的地市主要分布在黄河流域的下游和中游地区,相对而言,效率中等和效率低下的区域多分布在黄河上游地区。(2)农业社会化服务对粮食生态效率具有显著的正向空间溢出效应,即农业社会化服务既能显著提高本地区的粮食生态效率,而且能辐射带动邻近地区,这一结果经过一系列稳健性检验依然成立。(3)农业社会化服务对粮食生态效率的影响存在复杂的双重门槛效应和人均种植规模发展的适度区间,具体表现为随着人均种植规模的扩大,农业社会化服务对粮食生态效率的积极影响呈现非线性递减态势。

Abstract:

The development of agricultural socialized services is a critical component of agricultural modernization. Assessing their contribution to grain ecological efficiency under the “dual-security” framework of grain and ecology is essential for achieving sustainable agricultural development. This study employs panel data from 71 prefecture-level cities in the Yellow River Basin from 2011 to 2020 to examine the spatial spillover and nonlinear effects of agricultural socialized services on grain ecological efficiency. The results reveal that: (1) During the study period, grain ecological efficiency in urban agglomerations within the Yellow River Basin exhibited a clear upward trend. Spatially, efficiency levels were unevenly distributed, with cities rated as excellent or above primarily located in the midstream and downstream regions, while moderate- and low-efficiency areas were concentrated upstream. (2) Agricultural socialized services exert a significant positive spatial spillover effect on grain ecological efficiency, enhancing not only local performance but also positively influencing adjacent regions. This finding remains robust across multiple tests. (3) The effect of agricultural socialized services on grain ecological efficiency exhibits a complex dual-threshold behavior related to the development of per capita planting scale. Specifically, as planting scale increases, the positive impact of agricultural socialized services follows a nonlinear diminishing trend.
