Abstract

Under the background of rapid iteration of global digital technology, it is a key issue to explore its mechanism and differential influence on import and export trade. This paper constructs a "technology-market-system" analysis framework, and uses panel regression and case comparison methods to reveal that the development of digital economy affects the scale and quality of trade by reducing trade costs, expanding market boundaries and optimizing industrial structure. According to the differences of countries, industries and institutional environment in different stages of development, a multi-dimensional analysis framework is further constructed. Further analysis shows that the national development stage, industry technical attributes and policy openness constitute the core variables that affect the differentiation of effects-developing countries need to break through the double constraints of "digital divide" and "low-end lock-in", while developed countries face the risk of attenuation of innovation kinetic energy and loss of rule dominance. Based on this, this paper puts forward some policy suggestions, such as promoting digital infrastructure construction by classification, reforming anti-monopoly framework to promote technology diffusion, and constructing multilateral digital trade rules. These findings provide a theoretical basis for countries to formulate differentiated digital trade strategies, emphasizing the need to choose the path of technology catching up or rules leading in combination with their own development stages in order to enhance trade competitiveness in the wave of digital globalization.
