摘要
促进数字经济创新发展、释放数字技术赋能红利是新发展阶段推动中国产业结构转型升级的重要途径。构建多部门一般均衡模型,阐述数字经济创新、技术赋能偏向与产业结构转型之间的影响机理,并采用数值模拟方法进行定量分析,指出数字经济创新是生产要素在产业间优化配置的重要驱动力,技术赋能偏向在其中发挥着重要传导作用,而制造品、传统服务品与数字品之间的替代弹性差异决定要素流动方向。基于中国2005—2020年省级面板数据的实证研究表明,数字经济创新能有效推动产业结构向服务化转型,这一结论与数值模拟的第三种情形相似,且在采用工具变量、调整样本范围、替换解释变量、考虑遗漏变量、排除时间趋势后仍成立;机制检验发现,技术赋能偏向是数字经济创新推动产业结构转型的重要渠道,而市场机制是数字经济创新推动产业结构转型的更深层次途径。
Promoting the innovative development of the digital economy and unleashing the dividends of digital technology empowerment are important ways to promote the transformation and upgrading of China's industrial structure in the new development stage.By constructing a multi sector general equilibrium theory model,this paper expounds the impact mechanism between digital economy innovation,technology empowerment bias and industrial structure transformation,and quantitatively analyzes this impact by using numerical simulation methods.It is found that digital economy innovation is an important driving force for the optimization of production factors among industries,in which technology empowerment bias plays an important transmission role,while the difference in substitution elasticity between manufactured goods,traditional service goods,and digital goods determines the direction of factor flow.Further empirical analysis based on China's provincial panel data from 2005 to 2020 draws the following conclusions:digital economic innovation can effectively promote the transformation of industrial structure to service-oriented,which is similar to the third case of numerical simulation,and is still valid and under a series of robustness tests;Mechanism testing found that technology empowerment bias is an important channel for digital economy innovation to promote industrial structure transformation,while market mechanism is a deeper pathway for digital economy innovation to promote industrial structure transformation.
