    摘要:

    提高粮食生产韧性对保障粮食安全、加快建设农业强国具有重要意义。基于2005-2021年中国省级面板数据,构建粮食生产韧性评价指标体系进行水平测度,在此基础上深入分析其时空动态演进并展开趋势预测。研究表明:第一,考察期内中国粮食生产韧性水平总体呈现逐年提升态势,但近些年增速有所放缓。第二,各省份粮食生产韧性差异明显,整体呈现“东高西低”的特征,且总体差距在考察期内逐步扩大; 总体差异主要来源于区域间差异,但2017年后区域间差异逐渐下降,区域内差异逐步成为造成总体差异的主要原因;分区之间发展不平衡问题较为严峻,区域内省际差异明显。第三,中国粮食生产韧性存在较为显著的空间相关性,表现出明显的高-高集聚和低-低集聚特征,即高水平省份多与一个或多个高水平省份相邻,而低水平省份邻域多为低水平省份。第四,各省份粮食生产韧性在短期内较难实现层级跨越;而在引入空间地理因素后,粮食生产韧性的稳定状态有动摇趋势,易表现出“强者恒强,弱者恒弱”的马太效应。

    Abstract:

    Improving the resilience of food production is of great significance to ensure food security and accelerate the construction of an agricultural power. Based on China’s provincial panel data from 2005 to 2021, the evaluation index system of grain production resilience was constructed to measure the resilience level. And on this basis, the spatiotemporal dynamic evolution of the grain production was analyzed in depth followed by the trend prediction. The results are as follows: First, the overall level of food production resilience in China showed a year-on-year improvement trend during the study period, although the growth rate has slowed down in recent years. Second, there are obvious differences in the resilience of grain production among provinces, generally displaying a pattern of “being high in the east and low in the west” and the overall gap gradually widens during the study period. The main source of overall differences lies in regional disparities, but since 2017, interregional differences have gradually decreased, with intra-regional differences becoming the main cause of overall disparities. The problem of unbalanced development between sub-regions is more severe with obvious differences between provinces within the region. Third, there is a significant spatial correlation in the resilience of grain production in China, showing obvious characteristics of high-high and low-low agglomeration, where high-level provinces are mostly adjacent to one or more high-level provinces, while low-level provinces are mostly neighboring low-level provinces. Fourth, it is difficult for provinces to achieve a hierarchical leap in the resilience of food production in the short term. However, after the introduction of spatial and geographical factors, the stable state of grain production resilience has a tendency to fluctuate, often exhibiting a Matthew effect where “the strong remain strong and the weak remain weak”.
