数字经济产业结构升级与物流技术创新

Digital Economy,Industrial Structure Upgrade and Logistics Technology Innovation

文中以2010-2016年我国30省市的数据为样本,以实证的方式检验了数字经济的发展对物流行业技术创新的影响,结果显示:数字经济发展对物流技术创新水平存在非线性效应,并进一步以我国的产业结构升级为门限变量,发现存在单一门限效应,低于门限值时,数字经济系数为25.23,高于门限值时,数字经济系数为32.45,对物流技术创新作用呈现递进趋势。

The article uses the data of 30 provinces and cities in China from 2010 to 2016 as a sample to test the impact of the development of the digital economy on the technological innovation of the logistics industry in an empirical way.The results show that the development of the digital economy has a nonlinear effect on the level of logistics technological innovation.And further used the upgrading of China’s industrial structure as a threshold variable,and found that there is a single threshold effect.When the threshold is lower than the threshold,the digital economy coefficient is 25.23,and when the threshold is higher,the digital economy coefficient is 32.45,which showing a progressive trend in the role of logistics technology innovation.
