双循环下数字经济对高技术产业影响研究

双循环背景下,数字经济与高技术产业的融合有助于推动构建国内国际双循环格局加快实现,本文将数字经济分解为数字产业化、产业数字化,创造性的开发出在“数字生产函数”的框架下测算产业数字化的方式,并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。本文利用高技术产业数据以及所测度数字产业化、产业数字化相关指标数据,采用面板数据模型、面板门槛模型研究数字经济对与高技术产业产出包括外贸出口、国内需求的关系。研究发现：产业数字化对外贸出口的影响呈现正向作用,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产业数字化水平提升而增加,随国内需求水平提升先增大后减小

Research on the impact of digital economy on the development of high-tech industries under the background of dual cycles

In the context of the dual cycle, the integration of the digital economy and high-tech industries will help promote the construction of a domestic and international dual cycle pattern. This article decomposes the digital economy into digital industrialization and industrial digitization, and creatively develops the "digital production function". Measure the way of industrial digitization under the framework, and propose the influence mechanism of the digital economy on the development of high-tech industries, including foreign trade exports and domestic demand. This paper uses high-tech industry data and the measured digital industrialization and industrial digitization related index data, and uses panel data model and panel threshold model to study the relationship between digital economy and high-tech industry output, including foreign trade exports and domestic demand. The research found that: industrial digitalization has a positive effect on foreign trade exports, and digital industrialization has no effect on foreign trade exports; there is a "U"-shaped relationship between industrial digitalization and foreign trade exports, and there is a "U" between digital industrialization and domestic demand The relationship between digital industrialization and industrial digitization is mutually advancing, but the current level of synergy is not high; industrial digitization and foreign trade export levels are low, and the positive contribution of industrial digitization to foreign trade exports is not high; industrial digitization is positive for domestic demand The directional effect increases as the level of industrial digitization increases, and increases first and then decreases as the level of domestic demand increases.
