Implement high-level opening up，Building a new higher-level open bet365 score system，Is an important guarantee for our country to build a new development pattern。But why should we implement high-level opening up，What kind of new higher-level open bet365 score system should be built，What is the relationship between high-level opening up and the new development pattern，There are still various opinions。One view is，Since the new development pattern takes the domestic cycle as the main body，Then the main task in the future is to accelerate independent innovation and expand the domestic market，Therefore, it is closely related to high-level opening up、The difference between severity and severity。Another view is，Considering current protectionism、Isolationism and anti-globalization are coming，The bet365 score relationship between developed countries and our country will inevitably be affected，Not conducive to establishing mutual openness、Reciprocal and reciprocal bet365 score relationship，Thereby forcing us to look inward，Focus on bet365 score relations within itself and with surrounding developing countries。These understandings，Not completely unreasonable，But often only looking at one but not the other、Only look at the current misunderstanding and not the long-term misunderstanding。For this，The author makes the following analysis and discussion on this issue。

As everyone knows，Since the reform and opening up，After decades of rapid development，Our country has initially established an open economic system that is compatible with the socialist market economy with Chinese characteristics，The most important manifestation of this system is China’s accession to the World Trade Organization，Comprehensive integration into the world economic system，Become an important force in promoting economic globalization and building a new bet365 score。However，With the uneven development of the global economy，Especially the sudden rise of emerging market countries represented by China，The existing globalization structure ("echelon industrial transfer") and the supporting international economic and trade rules (trade and investment liberalization) and governance system (power is concentrated in a few developed countries) are becoming increasingly outdated，The structural contradictions that have led to the highlighting of the world economy。The outbreak of the global financial crisis in 2008 and the long-term downturn of the world economy since then，is a concentrated expression of this obsolescence and contradiction。After the crisis，The global economic system and the "center-periphery" structure are declining，Existing international rules are gradually failing，The new international order has yet to be established。Especially since the outbreak of the new coronavirus pneumonia，The economies of various countries around the world have been severely impacted，International trade and investment relations have also been greatly affected，Resulting in further intensification of various contradictions and interest disputes in international economic relations。At the same time，my country’s current economic development characteristics and transformation and upgrading requirements，Decided that we can no longer continue to act as a global supply chain、The role of low-end producers in the industrial chain，We must keep pace with the times and follow the general trend of China's economic transformation and upgrading，Actively become an important promoter of global economic development、The defender of the bet365 score，Accelerate the formation of new international trade and investment relationships。

Our country proposes to build a new development pattern，It is necessary to actively respond to the world’s major changes unseen in a century and promote the overall strategy of the great rejuvenation of the Chinese nation in the context of the times，Based on one’s own economic and social development needs and actual national conditions，As well as challenges and opportunities in the external economic environment，Pursuing a path of economic transformation and upgrading beyond the "center-periphery" pattern，And then gradually enter the ranks of high-income economies。In this process，Beyond the traditional international division of labor，Transforming from a low-end manufacturer to an “intelligent manufacturing center”，It must be at a higher level、Updated form、Deeper opening up，Establish new connections and connections with more countries and regions。Under the new development pattern，This new form of bet365 score，It is necessary，It is also very possible。On the one hand，From the perspective of necessity，Any country in today’s world must communicate and connect with the outside world，Leverage your own comparative advantages，Acquire international competitive advantage，This has been fully proven in international economic theory and China’s reform and opening up practice。On the other hand，From the perspective of possibility，By creating an open and win-win cooperation model，Enable global industrial chain、The innovation chain and the value chain are more closely connected，So that people from all over the world can share the fruits of economic globalization，Still the consensus of the vast majority of countries。Even when the international economic environment has been relatively sluggish in the past few years，China still has established a Regional Comprehensive Economic Partnership (RCEP) with neighboring countries，Completed negotiations with the EU on the China-EU Comprehensive Agreement on Investment (CAI)，We have also reached multiple high-level trade and investment agreements with other economies，This is a clear example。

Current，We build a bet365 score with domestic circulation as the main body，The biggest obstacles lie in the two major bottlenecks of independent technological innovation and expanding domestic demand market。To solve these two problems，It is inseparable from international exchanges and cooperation，Inseparable from high-level opening up。

In terms of independent innovation，Under the advantage bet365 score national system，Intensify efforts in basic research、Enhancing independent innovation capabilities is the key to breaking through the innovation bottleneck in our country，Especially the main way to solve the problem of "stuck neck" in key core technologies。In recent years，Our country has made remarkable achievements in high-tech R&D and application，Major breakthroughs have been made in many cutting-edge technological fields。However，Independent technological innovation does not exclude the use of external resources，Focus on multiple ways and possibilities of technological innovation。Actually，International technology transfer、Technology diffusion、Technical exchange、Technology spillover comes in various forms and channels，All these forms are inseparable from international exchanges。Actively introduce advanced manufacturing and service companies from developed countries，Between them and Chinese companies、In the process of dealing with customers and consumers，Conducive to the diffusion and application of foreign advanced technologies and business concepts in our country，Thus improving my country’s industrial basic capabilities and industrial chain level。This requires us to create marketization、Legalization、International business environment and competitive conditions，Moderately opening up industries or markets that are closely related to innovation activities，Fairer by building、Open、Transparent system rules，Ensure that all market entities can compete fairly，Promote the reasonable flow and optimal allocation of various resource elements。

As far as the domestic demand market is concerned，Building a new development pattern with domestic circulation as the main body，We must change the one-way dependence on foreign markets, especially the markets of major developed countries, in the past few decades，Leverage the advantages of ultra-large-scale market，Make domestic consumer demand the main engine of bet365 score growth。In this regard，With the gradual implementation of various policies of the party and the state on expanding domestic demand，The domestic market potential is being fully tapped，The proportion of domestic demand in bet365 score growth has steadily increased，And become the ballast stone for the stable operation of the economy。At the same time，Constructing a new development pattern also requires promoting mutual promotion of domestic and international dual cycles，Expanding domestic demand and actively expanding overseas markets go hand in hand、Complementing each other。Especially now that the COVID-19 epidemic has caused a severe recession in the world economy，We build a new development pattern，Exports still need to be regarded as one of the long-term driving forces of my country’s bet365 score growth，Through various bilateral and multilateral benign cooperation mechanisms，Actively carry out trade cooperation with countries around the world。Since the outbreak，The two-way significant growth of my country’s imports and exports proves the importance of this “dual circulation”。At the same time，Trade relations between my country and ASEAN and other regions are booming，ASEAN has become my country’s largest trading partner，Indicates the establishment of free trade zones and other means of opening up，Help promote the development of international trade and investment。Therefore，Unified opening through construction、Competition is orderly、Complete system、High-standard market system with perfect governance，China further expands import and export scale、Improve the quality of foreign trade and promote long-term bet365 score growth，It is completely achievable。
