基于2013-2022年省级面板数据,通过建立双向固定效应模型和中介效应模型,分析数字经济赋能实体经济发展的整体影响,检验数字经济赋能实体经济发展的中介机制.研究结果表明:数字经济赋能实体经济表现为正向促进作用,且在采用替换核心被解释变量与工具变量法控制内生性等稳健性检验后仍成立.从异质性分析看,省份处于不同的地理位置、数字经济发展处于不同时期以及数字经济发展处于不同水平,其实体经济发展水平均存在差异.进一步的机制检验发现,科技创新力度在数字经济发展对实体经济进行赋能过程中具有一定的中介效应.据此,需要进一步加大数字经济发展力度,加快数字经济发展基础设施建设,以科技创新促进实体经济发展壮大.
Based on provincial panel data from 2013 to 2022,this paper analyzes the overall impact of digital economy en-abling real economy on the development of real economy by establishing two-way fixed effect model and intermediary effect model,and tests the intermediary mechanism of digital economy enabling real economy development.The results show that digital economy enables real economy to play a positive role,and it is still valid after the robustness test such as replacing core explained variables and instrumental variables to control endogeneity.From the perspective of heterogeneity analysis,provinces are in different geographical locations,digital economy development periods and digital economy development levels,and their real economy development levels are different.Further mechanism test shows that the intensity of scientific and technological innovation has a certain intermediary effect in empowering the real economy with the development of digital economy.Accordingly,we will further strengthen the development of the digital economy,accelerate the construction of infrastructure for the development of the digital economy,and strengthen the development of the real economy.
