摘要
基于2012—2021年长江经济带省级面板数据,运用超效率SBM模型测算该经济带的农业生产效率,构建OLS模型分析该经济带农村人口老龄化对农业生产效率的影响。研究表明:①长江经济带2012—2021年农业生产效率水平较高,且表现出先减后增的趋势。在各区域当中,下游的农业生产效率值最高,上游最低,但各区域的效率值并无较大差距。各省(市)中,上海市的农业生产效率最高,而重庆市的效率值最低,且仅有重庆市的效率均值小于1。②回归分析结果表明,长江经济带农村人口老龄化对农业生产效率的影响显著为负。区域异质性分析表明,农村人口老龄化对上游农业生产效率提高有明显的抑制作用,对中游和下游则有明显的促进作用。
Based on the provincial panel data of the Yangtze River Economic Belt from 2012 to 2021,the super efficiency SBM model is used to measure the agricultural production efficiency of the economic belt,and an OLS model is constructed to analyze the impact of rural population aging on agricultural production efficiency in the economic belt.Research results show that:①The agricultural production efficiency level in the Yangtze River Economic Belt was relatively high from 2012 to 2021,and showed a trend of decreasing first and then increasing.Among various regions,the agricultural production efficiency values in the downstream are the highest,while those in the upstream are the lowest.However,there is no significant difference in efficiency values among different regions.Among all provinces(cities),Shanghai has the highest agricultural production efficiency,while Chongqing has the lowest efficiency value,and only Chongqing has an average efficiency of less than 1.②Regression analysis shows that the aging of rural population in the Yangtze River Economic Belt has a significant negative impact on agricultural production efficiency.Regional heterogeneity analysis shows that the aging of rural population has a significant inhibitory effect on the improvement of agricultural production efficiency in the upstream,while it has a significant promoting effect on the middle and downstream.
