From the regulatory model of "opening up the front line and regulating the second line", to the iterative upgrade of the policy of processing value-added without tariffs; From the negative list of cross-border service trade to the multifunctional free trade account system, each system is not an isolated "preference", but a mutually supportive and collaborative institutional ecosystem.

Currently, global economic and trade rules are undergoing profound adjustments, shifting from factor flow based openness to institutional openness such as rules, regulations, management, and standards, which has become a common direction for major economies in the world. The exploration of Hainan Free Trade Port is China's proactive move in this process. From the opening of the first seventh freedom passenger route to the transfer of funds between the multi-functional free trade account and 99 countries and regions, Hainan is becoming an important gateway connecting mainland China with the global market. In the long run, production factors are more willing to gather in institutional highlands. This is not a local experience of any region, but a fundamental law of global resource allocation. When the rules are predictable, the rule of law is guaranteed, and the market is open enough, capital, talent, and technology will naturally vote with their feet. The operation of customs clearance is only a "small lotus that can show its sharp edges", and the magnificent scene of "endless blue lotus leaves connecting the sky" will become the future of Hainan Free Trade Port.
