摘　　要：安徽省正处在全面融入长三角的重要战略机遇期,利用数字经济发展赋能产业升级已是当前阶段的重点任务。因此,以安徽省为研究对象,构造了数字经济发展与产业升级的指标体系,基于熵权法测度了二者的综合值,并运用面板门限回归模型,实证研究了2012—2019年全省及皖南、皖中、皖北数字经济发展对产业升级的影响效果。研究发现:总体来看,数字经济发展水平与产业升级水平均在不断上升,但区域差异较为明显,分省市的测度结果中合肥最高,皖南地区的数字经济发展水平最高。数字经济的发展能显著促进产业升级,而且这种推动作用具有阶段性特征,具体表现为数字经济发展水平越高,对产业升级的推动作用越强,但若区域差距较大,推动作用会被削弱。Using the development of digital economy to upgrade industry has become a key task when Anhui province is in an important stage to integrate into the Yangtze River Delta.This paper,taking Anhui province as the research object,constructs the digital economy development and industrial upgrading index system,measures the comprehensive value of the two based on the entropy weight method,and uses panel threshold regression model to study the effects of digital economy development in the whole Anhui province,southern Anhui,middle Anhui and northern Anhui on industrial upgrading from 2012 to 2019.The results show that,on the whole,both the development level of digital economy and the level of industrial upgrading are on the rise,but the regional differences are significant.Specifically,Hefei is the highest among the cities,and southern Anhui is the highest in digital economy level.The development of digital economy can significantly promote industrial upgrading,and this promoting effect has stages.Specifically,the higher the development level of digital economy,the stronger the promoting effect on industrial upgrading;but if there exist big differences between regions,the promoting effect will be reduced.
