Continuously expanding opening up to the outside world and improving the level of opening up to the outside world, promoting reform and development through opening up, is an important tool for China to continuously achieve new achievements in development. The important article "Steadfast Promotion of High level Opening up to the outside World" recently published by General Secretary Xi Jinping profoundly answers major theoretical and practical questions such as the significance, connotation, requirements, and improvement path of high-level opening up in the new era, providing action guidelines for implementing a wider range, wider scope, and deeper level of opening up to the outside world. At present, the high-level opening up has been continuously promoted, comprehensively deepened, and deeply integrated with the construction of Chinese path to modernization. Internally, a high level of opening up is an important path for China to develop new quality productive forces according to local conditions, which forms a positive interaction with Chinese path to modernization; From an external perspective, as an outward extension of Chinese path to modernization, the high-level opening up deeply conforms to the modernization aspirations of developing countries, and highlights the important era value and world significance in stabilizing the global economy, improving global governance, and driving the process of sustainable development. At present and for a period to come, we need to promote high-level opening up steadily, promote economic and trade cooperation, governance coordination, and inclusiveness, and open up broad prospects for promoting Chinese path to modernization and building a community with a shared future for mankind. General Secretary Xi Jinping pointed out that "China adheres to true multilateralism, promotes inclusive economic globalization, actively participates in global economic governance, and is committed to building an open world economy." As the economy that contributes the most to the world economy, China provides key impetus and broad prospects for the construction of an open world economy. To build an open world economy that is innovative and inclusive, we must accelerate the construction of a new development pattern with domestic circulation as the mainstay and domestic and international circulations mutually promoting each other. Firstly, the new development pattern provides solid support for an open world economy. The new development pattern is not only an inherent requirement for reconciling the contradictions between domestic productivity and production relations, but also a key path for coordinating China's economic and trade relations with other countries. Internally, relying on the world's most complete industrial system and the advantage of a super large market, we will unleash the potential of domestic demand, optimize the supply structure, and smooth the domestic economic cycle. Externally, relying on the innovative vitality and economies of scale of the domestic market, we aim to integrate into the global division of labor and cooperation network with higher quality, oppose protectionism and unilateralism, and lay a solid foundation for an open world economy. Secondly, an open world economy provides a platform for building a new development pattern. The two are deeply integrated, by reducing transaction costs and trade barriers between regions, promoting the free flow and optimized allocation of production factors on a broader scale. This not only injects new impetus into the economic development of partner countries, but also promotes the reintegration and extension of global industrial and supply chains, forming a closer and more diverse international economic cooperation network. Finally, the new development pattern and open economy have a profound impact. The close economic and trade exchanges and interest ties provide a common interest foundation for international rule consultation and multilateral mechanism operation, ensuring the steady progress of the construction of a new open economic system. The cross-border flow of goods, capital, technology, and talent has become a bridge for people from different cultural backgrounds to come into contact, understand, and cooperate, providing a wide range of direct channels for cultural dissemination, ideological collision, and scientific and educational cooperation, and nourishing the vitality of open and civilized exchanges. During the 14th Five Year Plan period, China's average annual contribution to world economic growth remained at around 30%, which not only demonstrated the effectiveness of building a new development pattern, but also confirmed the vigorous vitality of an open world economy. To further promote high-level opening up to the outside world, it is necessary to focus on key areas of high-quality development and make concerted efforts. Firstly, establish a solid foundation for the domestic circulation and empower an open economy. We can activate consumption momentum by expanding the middle-income group and optimizing the income distribution structure, accelerate the construction of a unified national market, resolutely break down local protection and market segmentation barriers, strengthen technological innovation to lead industrial upgrading, enhance the adaptability of the supply system to domestic demand, and consolidate the foundation of economic development autonomy. Secondly, high-quality integration into global division of labor, setting a benchmark and expanding the boundaries for an open economy. To build and develop free trade pilot zones and free trade ports, carry out larger scale and deeper level pilot projects, create new benchmarks for opening up to the outside world, and firmly uphold the multilateral trading system. Thirdly, expand the space for mutually beneficial and win-win cooperation, and gather momentum for an open economy. We need to optimize the layout of regional economic and trade cooperation, implement existing free trade agreements such as the Regional Comprehensive Economic Partnership with high quality, deepen practical cooperation with countries in the global South in areas such as infrastructure connectivity, production capacity cooperation, and market docking, promote the sharing of development opportunities, oppose all forms of protectionism, and jointly maintain the openness, stability, security, and smoothness of the global industrial and supply chains. Fourthly, optimize the cross-border factor flow environment to facilitate the smooth flow of open economy. Continuously improving the market-oriented, rule of law, and international first-class business environment, effectively protecting the legitimate rights and interests of foreign investment to enhance attractiveness, facilitating international personnel exchanges, promoting efficient and convenient flow of innovative elements such as knowledge, technology, and data, and improving the development level of service trade. 2. Building a more just and reasonable global governance system through institutional openness. General Secretary Xi Jinping pointed out: "We must steadily expand institutional openness, actively connect with international high standard economic and trade rules, deepen the reform of foreign trade, foreign investment, and foreign investment management systems, and create a market-oriented, legalized, and internationalized first-class business environment." To implement the global governance initiative and build a more just and reasonable global governance system, we must continue to promote institutional openness, form institutional driving forces for governance coordination, standardize the operation order of economic and trade cooperation, and build a dialogue framework for mutual learning among civilizations. Promote deep level reforms through institutional openness and shape a new ecology of global governance. Firstly, institutional openness provides fundamental support for governance collaboration. Institutional openness emphasizes the integration and coordination of rules, regulations, management, standards, and other aspects. It goes beyond traditional commodity and factor flow openness and focuses more on building a new open economic system that is connected to international high standard economic and trade rules at the institutional level, which is conducive to forming a unified, transparent, and predictable institutional environment. Secondly, governance synergy promotes global governance towards fairness and justice. On the one hand, fair and transparent international rules set a unified standard for global economic and trade activities, effectively constraining market monopolies and other distorted behaviors, reducing transaction costs and policy uncertainty. On the other hand, the global governance mechanism provides an institutionalized platform for dialogue among different civilizations and value systems, transcending cultural barriers, allowing different civilizations to express their demands, exchange and learn from each other through mutual respect, and promoting the shift of global governance from Western led to pluralistic co governance, and from power games to rule consensus. The standardized economic and trade order has reduced trade frictions and development imbalances caused by the lack of rules, creating a fair competition environment for all countries, especially developing countries. The institutionalized framework of civilization dialogue consolidates value consensus through rules, laying a cooperative foundation for addressing global challenges such as climate change and public health crises. Finally, China's practice confirms the governance value of institutional openness. At present, China's practice of promoting the connectivity of the "the Belt and Road" rules and standards, leading the discussion of global digital and green financial rules, and implementing the Regional Comprehensive Economic Partnership Agreement is to activate governance coordination and achieve international justice through institutional openness. Only by continuously strengthening this institutional driving force can we build a truly inclusive, universal, and sustainable new ecology of global governance. To further promote high-level opening-up to the outside world, it is necessary to continuously enhance the level of institutional opening-up. Firstly, promote two-way interaction of rules and enhance the adaptability of institutional openness. We should actively benchmark international high standard economic and trade rules, deepen domestic reforms in market supervision, intellectual property, data flow, and other fields, pass stress tests in free trade zones, and integrate with the international community while based on our national conditions; We also need to transform mature domestic experience into international rule proposals, leading consultations and cooperation in emerging fields such as digital economy and supply chain security, and achieving a transition from "adaptation rules" to "co creation rules". Secondly, establish a solid foundation for the business environment and enhance the attractiveness of institutional openness. Fully implement relevant laws and regulations on the protection of foreign investment, and ensure fair competition among all types of entities. Strengthen the full chain protection of intellectual property rights and enhance the credibility of law enforcement. Strengthen the promotion and interpretation of the policy of opening up to the outside world, stabilize policy expectations, make global investors willing to come, stay, and develop well, and transform institutional advantages into cooperative results. Thirdly, build a high-level open platform and expand the influence of institutional openness. High standard construction of free trade pilot zones and free trade ports, granting them greater autonomy in reform, and conducting breakthrough pilot projects in areas such as investment access, trade facilitation, and financial openness. Relying on national level platforms such as Chain Expo, CIIE, and Service Trade Fair, we will promote efficient integration of global factor resources and make the platform an important window to showcase the effectiveness of institutional openness and consolidate international consensus. Fourthly, empower partners to develop together and demonstrate the inclusiveness of institutional openness. Incorporate issues such as infrastructure gaps and technological gaps in developing countries into the core agenda, guide the directed flow of resources through rule design, and effectively transform institutional dividends into inclusive development momentum. General Secretary Xi Jinping pointed out that "we must use openness to alleviate development difficulties, harness the power of cooperation, gather innovation, and seek shared benefits, promote economic globalization, enhance the development momentum of all countries, and ensure that the development achievements benefit the people of all countries more and fairly." High level opening up to the outside world should be fundamentally aimed at improving people's livelihoods, clarifying the development direction of open economy, and consolidating consensus on the rules of open governance. High level opening up promotes high-quality development and paints a new picture of universal benefits for people's livelihoods. Firstly, inject the core of people's livelihood into economic and trade cooperation. Different civilizations contain common aspirations for people's livelihoods, which have pointed out the value direction for economic and trade exchanges, that is, to promote international economic and trade cooperation with the improvement of people's livelihoods as the core. It guides the balanced distribution of employment opportunities in the layout of the industrial chain, focuses on ensuring the supply of basic needs in trade exchanges, and enhances the ability of public services in investment cooperation, so that economic and trade activities always revolve around human development. Secondly, to strengthen the public opinion foundation for collaborative governance. The deep driving force behind global governance reform stems from the common pursuit of fairness and inclusiveness among different civilizations. Civilization mutual learning promotes the world to balance the basic needs of developing countries in resource allocation, accommodate the actual conditions of different development stages in standard setting, prioritize the rights and interests of disadvantaged groups in risk response, and ensure that governance coordination is always based on people's livelihoods. Once again, it should be transformed into practical benefits for people's livelihoods. Promote technology sharing to tilt towards poverty reduction, healthcare, education, and other livelihood areas, encourage policy coordination to focus on ensuring basic needs such as clothing, food, housing, and transportation, and transform common development from a concept to a tangible improvement of life for every family. For example, projects such as the China Laos Railway and the Ya'an Wanzhou High speed Railway in international cooperation create taxes and employment for the local people, so that people in different countries can truly feel the sense of mutual learning and cooperation of civilizations. To further promote high-level opening up to the outside world, it is necessary to take people's livelihood and universal benefits as the link. Firstly, activate the potential of people's livelihood through open industrial cooperation. In the layout of industrial opening up to the outside world, combining the industrial characteristics of different civilizations with the needs of people's livelihood, we aim to create integrated industrial clusters that not only inherit cultural skills but also create employment opportunities
