摘要:基于DEA-BCC法从投入和产出两个维度测算了2011—2022年31个省(区、市)的农产品冷链物流效率,利用Dagum基尼系数及其子群分解方法讨论了农产品冷链物流效率的区域差距及其来源,并采用核密度估计方法考察了我国农产品冷链物流效率的动态演化特征。结果显示:(1)研究期内,我国农产品冷链物流综合效率整体呈现上升趋势,但地区差异明显,形成“东部和中部强、东北地区次之、西部地区弱”的区域发展格局。(2)农产品冷链物流效率的总体基尼系数呈现下降趋势,表明地区间农产品冷链物流效率不均衡问题有所改善,且超变密度是农产品冷链物流效率差异的主要来源。(3)从农产品冷链物流效率的分布及演变特征来看,全国及四大区域的农产品冷链物流效率均存在极化现象,截至2022年,极化现象已有所改善。

Abstract:

Based on the DEA-BCC model, this paper measures agricultural-product cold-chain-logistics efficiency across 31 provincial-level administrative regions of China from 2011 to 2022 from input-output dimensions. It employs the Dagum-Gini-coefficient decomposition method to discuss regional-efficiency gaps and their sources, and applies kernel-density estimation to investigate dynamic evolutionary features of China’s agricultural-product cold-chain-logistics efficiency. The results show three major findings. First, overall agricultural-product cold-chain-logistics efficiency in China exhibited upward trends during the sample period yet displayed obvious regional disparities, forming a spatial pattern with stronger performance in eastern and central regions, moderate levels in the northeastern region, and weaker outcomes in western regions. Second, the overall Gini coefficient for cold-chain-logistics efficiency declined, indicating alleviated inter-regional imbalance; transvariation intensity represents the principal source of efficiency differentials. Third, efficiency polarization exists both nationwide and within the four major regions, though such polarization had been mitigated by 2022.


Key words: agricultural products, cold chain logistics, efficiency, regional differences, evolutionary characteristics
