摘要
通过分析数字经济对农产品流通全要素生产率(TFP)的影响,研究数字经济如何更好赋能农产品流通增效。选取2013-2021年中国省级面板数据,构建双固定效应模型、影响机制检验和门槛效应检验模型,并且进行异质性检验,分析数字化对农产品流通效率的影响。研究发现:第一,数字化对提升农产品流通TFP具有显著正向影响,数字化能够有效提升农产品流通TFP。第二,数字化提升农产品流通TFP的效果南方比北方地区更显著;提升丘陵地区农产品流通TFP效果比平原地区的更显著;政府科技支持度高的地区在数字化对农产品流通TFP的影响上比支持度低的地区更显著。第三,数字化通过提升农村物流发展水平和居民消费水平来提升农产品流通TFP。第四,数字化对提升农产品流通TFP作用具有“门槛效应”,即随着地区数字化水平提升并跨越一定门槛值时,数字化对农产品流通TFP积极性影响呈现出递减型非线性特征。
By analyzing the impact of the digital economy on the total factor productivity of agricultural product cir-culation(TFP),this paper aims to explore how the digital economy can better empower the efficiency improvement of agricultural product circulation.It selects the provincial panel data of China from 2013 to 2021,constructs a two-way fixed effects model,the influence mechanism test and the threshold effect test model,and conducts the heterogeneity test to analyze the impact of digitalization on the circulation efficiency of agricultural products.Re-search has found that,firstly,digitization has a significant positive impact on improving the TFP of agricultural product circulation,and digitization can effectively enhance the TFP of agricultural product circulation.Secondly,the effect of digitalization on improving the TFP of agricultural product circulation is more significant in the south than that in the north;The effect of improving the TFP of agricultural product circulation in hilly areas is more sig-nificant than that in plain areas;Regions with a high degree of government technological support have a more sig-nificant impact of digitalization on the TFP of agricultural product circulation than those with a low degree of sup-port.Thirdly,digitalization enhances the TFP of agricultural product circulation by improving the development lev-el of rural logistics and the consumption level of residents.Fourthly,digitalization has a“threshold effect”on im-proving the TFP of agricultural product circulation,that is,as the level of digitalization of a region increases and crosses a certain threshold,the positive impact of digitalization on the TFP of agricultural product circulation shows a decreasing non-linear characteristic.
