| 摘 要： | 通过测度我国生鲜农产品冷链物流空间效率，对全国31省市生鲜农产品冷链效率差异进行分析，对提升农产品冷链物流效率提出对策建议。以全国31个省市为分析对象，采集2017—2021年面板数据，利用DEA 3.0从静态和动态两个维度对我国各省市农产品冷链物流空间效率进行测度，构建CCR模型和BCC模型分析静态效率，利用Malmquist指数分析动态效率。结果表明：我国整体冷链物流效率水平较高，但距离DEA效率前沿面还存在一定差距，各地区冷链物流效率呈现出空间差异性，技术进步变化对全要素生产力有显著推动作用。提出要提升农产品冷链物流效率各地区需结合实际情况，加大政府规划指引，促进冷链物流技术革新，培养冷链物流技术人才，提高冷链物流管理水平，促进我国农产品冷链物流协调发展。

| Abstract: | This article measures the spatial efficiency of cold chain logistics for fresh agricultural products in China, analyzes the differences in cold chain efficiency of fresh agricultural products in 31 provinces and cities across the country, and proposes countermeasures and suggestions to improve the efficiency of cold chain logistics for agricultural products. The panel data from 2017 to 2021 of 31 provinces and cities in China were collected, and DEA 3.0 was used to measure the spatial efficiency of cold chain logistics of agricultural products in each province and city from the static and dynamic dimensions, then the CCR model and BCC model were constructed to analyze the static efficiency, and the Malmquist index was used to analyze the dynamic efficiency. The results showed that the overall efficiency level of cold chain logistics in our country was relatively high, but there was still a certain gap from the efficiency frontier of DEA, the efficiency of cold chain logistics in different regions presented spatial differences, and technological progress and changes have a significant driving effect on total factor productivity. Therefore, this article proposes that in order to improve the efficiency of cold chain logistics for agricultural products, various regions need to combine the actual situation, increase government planning guidance, promote cold chain logistics technology innovation, cultivate cold chain logistics technology talents, improve the level of cold chain logistics management, and promote the coordinated development of cold chain logistics for agricultural products in China. |
