摘要
本文将数字经济分解为数字产业化、产业数字化,创造性地开发出在“数字生产函数”的框架下测算产业数字化的方式。随后提出数字经济对高技术产业发展包括外贸出口、国内需求的影响机制,并采用面板数据模型、面板门槛模型进行了实证研究。研究发现:产业数字化对外贸出口存在正向影响,数字产业化对外贸出口无影响;产业数字化与外贸出口之间存在“U”型关系,数字产业化与国内需求之间存在“U”型关系;数字产业化与产业数字化之间具有相互推进关系,但当前协同水平不高;产业数字化、外贸出口水平低,产业数字化对外贸出口的积极贡献也不高;产业数字化对国内需求的正向作用随国内需求水平提升先增大后减小。
At present,China is at the juncture of great changes that have not been seen in a century.The dual cycle strategy is a long-term strategy put forward by China based on the change of its internal and external environment and the demand for high-quality economic development.Following its strategic positioning,the key is to break the monopoly and master the core technology.The integration of digital economy and high-tech industry helps to promote the construction of domestic and international dual cycle pattern and accelerate the realization,In the context of dual cycle,it is very important to analyze the impact of digital economy on the development of high-tech industry for the accelerated realization of domestic and international dual cycle strategy.In view of this,this paper attempts to study the following contents:how to measure the digital economy(Digital industrialization and industrial digitization)What is the impact mechanism of digital economy on the development of high-tech industries(foreign trade export and domestic demand)What are the characteristics of the relationship between digital economy and the development of high-tech industries(foreign trade export and domestic demand)This paper decomposes the digital economy into digital industrialization and industrial digitization,draws lessons from the research of Li Yan and other scholars,takes the GDP digital industrialization of the core industry of the digital economy as an alternative variable of digital industrialization,and creatively develops a way to calculate the industrial digitization(GDP industrial digitization)under the framework of"digital production function".Then,taking the high-tech industry as the research object,this paper analyzes the impact mechanism of digital economy on the development of high-tech industry,including foreign trade export and domestic demand.In the impact mechanism of digital economy on foreign trade export,starting from digital industrialization,it includes:network connection effect,cost saving effect and international industrial chain cycle.Starting from industrial digitization,including economies of scale,optimization of industrial structure,tradability of services,upgrading of value chain,improvement of export technology complexity and optimization of trade environment.In the impact mechanism of digital economy on domestic demand,starting from digital industrialization,including strengthening the demonstration effect,optimizing the consumption structure,expediting emerging industries and improving the industrial chain.Starting from industrial digitization,it includes:economies of scale effect,economies of scope effect,production cost reduction,industrial innovation effect,industrial structure optimization and factor allocation reform.Using the high-tech industry data and the measured digital industrialization and industrial digitization related index data,this paper uses panel data model and panel threshold model to study the relationship between digital economy and high-tech industry output,including foreign trade export and domestic demand.It is found that the impact of industrial digitization on foreign trade export is positive,and digital industrialization has no impact on foreign trade export;There is a"U"relationship between industrial digitization and foreign trade export,and a"U"relationship between digital industrialization and domestic demand;There is a relationship between digital industrialization and industrial digitization,but the current level of synergy is not high;The level of industrial digitization and foreign trade export is low,and the positive contribution of industrial digitization to foreign trade export is not high;The positive effect of industrial digitization on domestic demand increases with the improvement of industrial digitization level,and first increases and then decreases with the improvement of domestic demand level..
