数字经济促进经济高质量发展:一个理论分析框架

Digital Economy Promotes High-quality Economic Development:A Theoretical Analysis Framework

在经济增速放缓的大背景下,基于互联网及相应新兴技术产生的新型经济形态——数字经济,却表现出蓬勃发展的态势。本文在梳理我国数字经济发展特征的基础上,从微观、宏观两个层面探讨了数字经济与经济增长的关系及其促进经济高质量发展的内在机理。在微观层面,互联网、移动通信、大数据、云计算等新兴技术可以形成兼具规模经济、范围经济及长尾效应的经济环境,在此基础上更好地匹配供需,形成更完善的价格机制,由此提高经济的均衡水平。在宏观层面,数字经济可以通过三条路径促进经济增长,即新的投入要素、新的资源配置效率和新的全要素生产率,数字经济还具有一种类似斯密提出的自增长模式。最后,本文认为数字经济的快速发展可以为我国现代化经济体系建设提供更好的匹配机制与创新激励。

Under the background of slowing economic growth, the digital economy, which is a new economic form based on the Internet and corresponding emerging technologies, has shown a booming trend. On the basis of combing the development characteristics of China’s digital economy, this paper explores the relationship between digital economy and economic growth and its internal mechanism to promote high-quality economic development from the micro and macro levels. At the micro level,emerging technologies such as the Internet, mobile communications, big data and cloud computing can form an economic environment with economies of scale, economies of scope and long tails. On this basis, it can better match the supply and demand and form a better price mechanism, thereby raising the level of economic equilibrium. At the macro level, it is proposed that the digital economy can promote economic growth through three paths, namely, new input factors, new resource allocation efficiency and new total factor productivity. It also points out that the digital economy has a self-growth model similar to what Smith proposed.Finally, this paper believes that the rapid development of the digital economy can provide a better matching mechanism and innovation incentives for the construction of China’s modern economic system.
