The concept of open development has profound theoretical logic. Human history has developed through openness. Today, the global nature of human interaction is deeper and more extensive than ever before, and countries are interconnected and interdependent with each other more frequently and closely than ever before. The more the times move forward, the more prominent the importance of opening up to the outside world becomes. The concept of open development has a profound historical logic. From the poverty and weakness accumulated during the period of isolationism to semi colonial and semi feudal periods, to the arduous exploration of the "one-sided" and closed and semi closed stages after the founding of New China, and to the historic transformation of China's relationship with the world through all-round opening up since the reform and opening up, the practice of China's relationship with the world has proven that in order to develop and grow, it is necessary to follow the trend of economic globalization, adhere to opening up, and fully utilize the advanced scientific and technological achievements and beneficial management experience created by human society. The concept of open development has profound practical logic. The concept of open development is not derived out of thin air, but is proposed in response to issues such as China's overall level of opening up to the outside world being not high enough, its ability to make good use of both domestic and international markets and resources being not strong enough, its ability to cope with international economic and trade frictions and fight for international economic discourse power being relatively weak, and its ability to apply international economic and trade rules being not strong enough. To implement the concept of open development, it is necessary to adhere to the basic national policy of opening up to the outside world, pursue a mutually beneficial and win-win strategy of opening up, deepen cultural exchanges, improve the regional layout, foreign trade layout, and investment layout of opening up to the outside world, form a new system of opening up to the outside world, develop a higher-level open economy, and expand opening up to drive innovation, promote reform, and promote development. On the basis of accurately grasping the new trends of economic globalization and the new requirements of China's opening up to the outside world, this is a major decision deployment to promote a higher level of opening up with more active and promising actions. Its overall goal is to accelerate the cultivation of new advantages in international cooperation and competition, more actively promote the balance between domestic and foreign demand, import and export, foreign investment and foreign investment, gradually achieve basic balance of international payments, form a new pattern of all-round opening up, modernize the open economic governance system and governance capacity, establish a correct concept of interests in expanding opening up, effectively safeguard national interests, safeguard national security, promote common development between China and countries around the world, and build a new open economic system that is mutually beneficial, diversified, safe and efficient. Since the 18th National Congress of the Communist Party of China, China has focused on breaking down institutional and institutional barriers, accelerating the construction of open highlands such as free trade pilot zones and free trade ports, and continuously promoting institutional integration and innovation. Since 2013, in accordance with the decisions and deployments of the Central Committee of the Communist Party of China and the State Council, 22 free trade pilot zones have been established in six batches, including Shanghai, Guangdong, Liaoning, Hainan, Shandong, and Beijing, forming a reform and opening up innovation pattern that covers the east, west, north, south, and central regions, and coordinates the coastal, inland, and border areas. Over the past decade, a total of 302 institutional innovation achievements in free trade pilot zones have been replicated and promoted at the national level. Each province, region, and city has independently promoted and replicated over 2800 achievements. After the launch of the construction of Hainan Free Trade Port in 2018, a total of 15 batches of 134 institutional innovation achievements have also been released. These institutional innovations involve investment facilitation, trade facilitation, financial openness and innovation, in-process and post event supervision, and state-owned enterprise reform, promoting the sustained release of reform dividends. China continuously improves laws related to foreign trade and investment, strengthens the promotion and protection of foreign investment through legislation, adheres to promoting high-level opening up to the outside world on the basis of the rule of law, promotes foreign-related rule of law construction in expanding opening up, and continuously solidifies the foundation of high-level opening up under the rule of law. The continuous improvement of China's new open economy system not only enhances the institutionalization and legalization level of opening up to the outside world, but also better strives for strategic initiative in open development, and effectively promotes the construction of a high-level socialist market economy system. The new pattern of comprehensive opening up has rich connotations, including expanding the scope of opening up, expanding fields, deepening levels, as well as innovating open methods, optimizing layout, and improving quality, which has profound strategic significance. To promote the formation of a new pattern of comprehensive opening up, we must adhere to a better combination of bringing in and going out. Utilizing foreign investment is China's long-term policy. China's policy of utilizing foreign investment will not change, the protection of the legitimate rights and interests of foreign-invested enterprises will not change, and the direction of providing better services for enterprises from various countries to invest and develop in China will not change. It should also be noted that transitioning from a major trading country to an investment country, and from commodity exports to capital exports, is a necessary path for the transformation and upgrading of an open economy. Since the new era, China's outward investment has remained among the top three in the world, which not only helps to improve the quality and efficiency of the national economy, but also promotes the economic and social development of the host country, achieving mutual benefit and win-win results. To promote the formation of a new pattern of comprehensive opening up, we must adhere to a better combination of coastal opening up and inland and border opening up. To promote the formation of a new pattern of comprehensive opening up, we must adhere to a better combination of openness in the manufacturing and service sectors. The service industry is an important area of international economic and trade cooperation. Since the 18th National Congress of the Communist Party of China, while deepening the opening up of the manufacturing industry, China has orderly lifted restrictions on foreign investment access and shareholding in competitive fields such as childcare and elderly care, architectural design, accounting and auditing, commercial logistics, e-commerce, as well as general manufacturing and service industries, and continued to create a market-oriented, legal, and international business environment. To promote the formation of a new pattern of comprehensive opening up, we must adhere to a better combination of opening up to developed countries and opening up to developing countries, comprehensively develop equal and mutually beneficial cooperation with other countries, and achieve diversification of export markets, import sources, and investment partners. To promote the formation of a new pattern of comprehensive opening up, we must adhere to a better combination of multilateral and regional opening up, actively participate in the reform and construction of the global governance system, support the multilateral trading system, promote the construction of free trade zones, and promote the construction of an open world economy. Since the new era, China has actively participated in global economic governance and promoted the formation of a joint force for world common openness. In promoting the improvement of a more just and reasonable global economic governance system, China firmly upholds the multilateral trading system, supports the core role of the World Trade Organization through practical actions, actively promotes trade and investment liberalization and facilitation, and resolutely opposes unilateralism and protectionism; Strengthen coordination and cooperation with international and multilateral mechanisms such as the United Nations, the G20, and the BRICS countries, firmly uphold the core position and role of the United Nations in international affairs, actively promote the transformation of the G20 from crisis response mechanisms to long-term economic governance mechanisms, and continuously propose and enrich constructive Chinese ideas for promoting BRICS cooperation; Deepen regional and sub regional cooperation, actively participate in regional cooperation mechanisms such as the Asia Pacific Economic Cooperation and the Shanghai Cooperation Organization, and promote the continuous deepening and expansion of sub regional cooperation such as the Lancang Mekong River cooperation. In promoting the formulation of economic governance rules in emerging fields, we actively promote the formulation of investment facilitation rules, strengthen international cooperation in the digital economy field, improve our ability to participate in international financial governance, and change the situation where developing countries are significantly underrepresented in the global financial governance system. Since the new era, China has always adhered to the principle of mutual benefit and win-win results, constantly expanded the convergence of interests with countries around the world, and deepened and expanded foreign economic and trade relations based on the major cooperation initiative of jointly building the "the Belt and Road". In terms of promoting infrastructure connectivity, China has strengthened the construction of key channels, established the basic framework of "six corridors, six routes, multi countries and multi ports" with countries that jointly build the "the Belt and Road", promoted China Europe Train to become the landmark brand of the "the Belt and Road", and officially launched a new channel for international land and sea trade. China has also built a series of economic and trade cooperation zones at a high level in cooperation with the countries jointly building the "the Belt and Road", and actively promoted the construction of the digital silk road. In terms of trade and investment cooperation, China and the countries jointly building the "the Belt and Road" actively develop mutually beneficial trade and investment cooperation relations, promote the establishment of a more balanced, equitable and sustainable trade system, and work together to make the "cake" of cooperation bigger and better
