Abstract: The General Agreement on Trade in Services (GATS) defines trade in service into four modes of supply: cross-border supply, consumption abroad, commercial presence, and movement of natural persons. Cross-border supply is mainly supported by digital technology to promote the expansion and efficiency of trade in service. Consumption abroad mainly expands the scale and optimizes the structure of trade in service through the effect of demand, system supply, and enterprise innovation. Commercial presence mainly enhances the competitiveness of trade in service through factor optimization effect. The movement of natural persons mainly aims at cost reduction and efficiency improvement of trade in service through the information effect and the spillover effect of technology. Drawing on experience from successful international free trade ports, we find that in the mode of cross-border supply, data flows freely and conveniently; in the mode of consumption abroad, cross-border funds flows freely and conveniently; in the mode of business presence, investment is free and convenient; and in the mode of movement of natural persons, people have relatively more freedom for entry and exit. All of this provides important reference for the development of trade in service in Hainan Free Trade Port.
