数字经济提高生鲜农产品绿色物流效率了吗?——基于交易成本的考察

Does Digital Economy Improve Green Logistics Efficiency of Fresh Agricultural Products?——Investigation Based on Transaction Costs

数字经济逐渐成为平衡交易成本和物流效率关系的新型载体和重要途径。运用2009—2020年中国30个省级面板数据,实证检验数字经济对生鲜农产品绿色物流效率的影响及交易成本在其中的调节效应。研究表明,数字经济对生鲜农产品绿色物流效率呈现出“U型”非线性关系。同时,交易成本负向调节数字经济对生鲜农产品绿色物流效率的影响,其中制度性交易成本的负向调节作用显著,市场交易成本的负向调节作用不显著。进一步研究表明,我国生鲜农产品绿色物流效率存在显著的时间“滚雪球”效应和空间“促增”效应,城镇化水平和人口密度显著正向提升了地方生鲜农产品绿色物流效率,但人均收入水平、交通基础设施和产业结构的影响尚不显著。

Digital economy has gradually become a new carrier and an important way to balance the relationship between transaction cost and logistics efficiency.Based on the panel data of 30 provincial levels in China from 2009 to 2020,the paper empirically tested the impact of digital economy on green logistics efficiency of fresh agricultural products and the adjustment effect of transaction cost in it.The results show that digital economy has a U-shaped nonlinear relationship with green logistics efficiency of fresh agricultural products.At the same time,transaction costs negatively moderated the impact of digital economy on green logistics efficiency of fresh agricultural products,in which institutional transaction costs had a significant negative regulatory effect,while market transaction costs had no significant negative regulatory effect.The further study showed that the green logistics efficiency of fresh agricultural products had significant time"snowball"effect and space"promotion"effect,and the urbanization level and population density significantly improved the green logistics efficiency of local fresh agricultural products,but the per capita income level,transportation infrastructure and industrial structure are not significant.
