In terms of trade, the downsizing of the negative list is conducive to expanding the open trade space. At present, trade in services has become a new engine of global free trade. With the progress of science and technology, e-commerce and other means of trade upgrades, trade in services and trade links become increasingly close. Orderly expansion of the service industry opening up, we must change the goods trade era of dependence on the approval of the management approach to speed up the implementation of pre-access national treatment and negative lists, narrow the scope of negative list restrictions. The full implementation of the negative list will help to improve the level of opening up trade in services and expand the opening of the common trade space. This is also the Hangzhou G20 summit, China to promote trade and investment coordination, and create a more open global trade and investment environment efforts.

 

       In the case of foreign interests, a downsizing of the negative list will help expand the global trade value chain. The rapid development of global value chain trade has profoundly changed the pattern of world economy. To create an "open, inclusive, shared" global value chain, the need for including developing countries, SMEs, including more people to join them. By reducing negative inventories and expanding open space, China can encourage developing countries, especially low-income countries, to participate in the global value chain and move to higher levels at a higher level and more value-added. On this basis, China to infrastructure interconnection as the basis, is conducive to promoting investment facilitation, build a higher standard of trade platform. Thereby creating a trade network through the global value chain, improving the global trade ecology, achieving trade upgrading and sustainable development.

 

       In an open economy, a downsizing of the negative list would help build an open global trading platform. An open economy means that the globalization of all people requires deep involvement of each country's economy. In the service trade and other emerging trade as the engine of trade growth today, the global trading rules system needs to be upgraded.

 

       The current multilateral trading system is facing challenges. Some countries have used the rapid updating of trade methods to organize the so-called "high standard" trade circle, leading to fragmentation of the global trade system and hindering the sustainable development of global trade. China opposes trade coterieism and promotes the facilitation and liberalization of international trade by reducing negative lists. And finally through the negative list to open the new space for the construction of new trading platforms, such as e-commerce, public entrepreneurship platform to provide impetus. In order to create an open, transparent and conducive global investment policy environment, promote international and domestic investment policy coordination, and promote inclusive economic growth and sustainable development, G20 proposed the "G20 Global Investment Guideline" for global trade and investment Transformation and upgrading to open a new door.
