摘要
推动数字经济发展与提升农产品冷链物流效率,是推进中国式现代化进程的关键策略。基于2011—2022年我国数字经济与农产品冷链物流的面板数据,运用固定效应和中介效应计量模型,探究数字经济对农产品冷链物流效率的影响机理。研究发现:数字经济能够提升农产品冷链物流效率,且存在区域异质性。东部地区数字经济的促进作用强于中西部地区,但均呈现不显著的正向影响;南方地区数字经济的促进作用强于北方地区,且影响显著为正。此外,数字经济可通过扩大生鲜农产品交易规模间接提升农产品冷链物流效率,表明生鲜农产品交易规模在二者关系中具有中介效应。
Promoting the development of digital economy and improving the efficiency of cold chain logistics of agricultural products are key strategies for advancing Chinese-style modernization.Based on the panel data of China's digital economy and agricultural cold chain logistics from 2011 to 2022,this study uses fixed effects and mediation effect econometric models to explore the impact mechanism by which the digital economy affects the efficiency of agricultural cold chain logistics.The results indicate that the digital economy can promote the efficiency of cold chain logistics for agricultural products,with notable regional heterogeneity.The promotion effect of the digital economy is stronger in eastern China than in central and western regions,but neither is significantly positive.In contrast,the promotion effect of digital economy is stronger in southern regions than in the north,and it is significantly positive.Furthermore,the digital economy can indirectly improve the efficiency of cold chain logistics for agricultural products by expanding the transaction volume of fresh agricultural products,suggesting a mediating effect of transaction scale in the relationship between the digital economy and logistics efficiency.
