摘　　要：农产品流通效率事关我国粮食安全和全国统一大市场的建成。运用熵值法测度了2011—2022年我国31个省级行政区的农产品流通效率,并使用Moran’s I、Kernel核密度估计、Markov链、Dagum基尼系数和β收敛模型分别分析了我国农产品流通效率的时空演变、地区差异与收敛性情况。结果显示:研究期内我国农产品流通效率存在显著正向空间相关性,“高—高”集聚和“低—低”集聚特征明显;核密度曲线宽度变大呈现右拖尾和高度差明显的双峰形态,表明农产品流通效率逐渐提升,地区内部存在极化趋势;相邻省区市空间滞后水平对本省区市农产品流通效率维持原有状态或向更高水平发展均有较大影响;地区间差异是造成农产品流通效率总体差异显著的主要原因;农产品流通效率存在显著绝对β收敛和条件β收敛。据此,对如何提高农产品流通效率和缩小地区间差距提出了相关政策建议。The agricultural product circulation market is related to whether the supply and demand of agricultural products can be effectively connected,and its construction and efficiency level will directly affect China’s food security and the completion of a unified national market.This paper uses the entropy method to measure the circulation efficiency of agricultural products in 31 provinces in China from 2011 to 2022,and analyzes the spatiotemporal evolution,regional differences and convergence of agricultural product circulation efficiency by using Moran’s I,kernel density estimation,Markov chain,Dagum Gini coefficient andσandβconvergence models.The results showed that there was a significant positive spatial correlation between the circulation efficiency of agricultural products in China during the study period,and the characteristics of“high-high”agglomeration and“low-low”agglomeration were obvious.The width of the kernel density curve became larger,showing a bimodal pattern with obvious right tailing and height difference,indicating that the circulation efficiency of agricultural products was gradually improved,and there was a polarization trend in the region.The spatial lag level of neighboring provinces has a great impact on the circulation efficiency of agricultural products in the province to maintain the original state or develop to a higher level.Regional differences are the main reasons for the significant differences in the overall circulation efficiency of agricultural products.There is noσconvergence in the circulation efficiency of agricultural products,but there is a significant convergence of absoluteβand conditional convergenceβ.Accordingly,this paper puts forward relevant policy suggestions on how to improve the circulation efficiency of agricultural products and narrow the gap between regions.
