The current world is undergoing a big change in a century，New Crown Pneumonia Epidemium Global Popularity has not subsided，The political and economic game of the world's great powers becomes more and more intense，Extension of international economic and trade friction and impact of international supply chain，Strict and complex and uncertain external environment leads to a highly dependent external supply chain facing huge decourse and broken risks，It also threatened the security and stability of the Chinese industrial chain。At the same time，Reform and opening up for more than 40 years, especially since joining the WTO，China actively integrates into the global value chain division system with factor advantages，It has become an important node and base for the global economic reinforcement。Based on the international situation and the overall situation of stable development in China，The Party Central Committee proposes to build a large domestic cycle in a timely manner、New development pattern of mutual promotion of domestic and international dual cycles。The new development pattern is not a closed domestic cycle，but the open domestic and international dual cycles。The basis of the orderly development of the circular economy lies in the smooth progress of social reproduction。In the process of building a new development pattern，Micro -enterprise products and factor markets facing the biggest challenge，Internal needs、Time and space mismatch and structural imbalance between element supply and product supply，and a direct effective way to unblock domestic large -cycle development，It is to guide the internalization of external circulation to open the value chain blocking point，Then create a new supply and demand system。Internalization of external circulation is different from import substitution，Also different from export to domestic Bet365 lotto review sales，Instead, the international cycle that is blocked by the domestic supply and demand is，Reconstruction of the underlying logic of the global value chain and the design of international economic and trade rules。

External circulation internalization is a direct means to expand the internal cycle，It is a potential and important path for building a new development pattern。Realizing domestic large cycle needs to expand domestic demand，Adjust the circulation of domestic supply and improve product elements，This can be strengthened based on the existing domestic economic cycle，It can also be achieved by creating a new domestic economic cycle chain。External circulation internalization via big data mining，Find an export company that can meet the product and quality needs of imported enterprises at the micro level，Export suppliers and imported demanders who are about to be adapted to supply and demand are matched，So as to establish a new domestic value chain or potential domestic value chain association，Provides new implementations for expanding the internal cycle。

Internalization of external circulation helps China to participate in international circulation at higher quality and higher levels。At the micro level，For exporters，External circulation internalization can not only help it expand the domestic market，Generate a stronger local market effect，Then get cost advantages and higher profits，It can also identify high -efficiency and high -quality potential domestic suppliers，Eliminate inefficient and low -quality backward production capacity，Improve the supply side quality，to help domestic suppliers better participate in the international cycle。For imported demanders，Internalization of external circulation can expand the source of the inter -interstitial and final consumer goods，Therefore, the economic benefits from the diversity of the product and the cost savings brought by the replacement of domestic products。At the macro level，As a world economy country，China's changes in global supply or demand will produce a general bet365 live casino games balanced effect，Change your own trade conditions，It even affects the reinforcement of the global industrial chain supply chain，Therefore, the profit of consumer welfare and local enterprises in China，and China's status in the global value chain。

Internalization of external circulation can provide guarantees for the security and economic development of the industrial chain supply chain under the new development pattern。Internalization of external circulation, on the one hand, by matching import and export companies that match supply and demand adaptation，Establish a real or potential domestic supply chain link，Reconstruction value chain system，So weakening or avoiding the threat of the supply chain caused by external impact on the economic cycle; on the other hand, it can study the potential shortcomings and blockage points of the industrial chain in advance，Then formulate targeted measures，Maintenance of the supply chain of its own industrial chain。China's economic development has the potential of a large cycle of the domestic market，Internalization of external circulation can improve the benefits of domestic demanders and national trade conditions，Objectively helps to accelerate the dual pinch of "low -end lock" and "high -end blockade"，Provide a strong motivation for accelerating the construction of a new development pattern。

　　External circulation internalization has industry heterogeneity

China has the world's most complete and largest industrial production system，Regional cultural differences and ethnic composition diverse，Have huge consumption potential and demand heterogeneity，This provides an important motivation for the integration of industrial division of labor and supply and demand for external circulation。From the perspective of supply and demand matching，At present, the overall potential of Chinese external circulation internalization is more than 60%。But the potential and change trends of external circulation have obvious industry heterogeneity。Where，The internal cycle potential of the basic manufacturing industry occupies the main position，Its potential adaptation is as high as 80%or more，and the trend of steady rising bet365 Play online games in time; the potential of high -tech manufacturing internalization is lower than the basic manufacturing，and the trend of fluctuations in time trend; the primary product industry includes agricultural products and resource products，The potential of its external circulation internalization is extremely low，and there is no rise in time。The reasons for the above trends may be as follows: (1) The rapid development of China's productive service industry and the integration of basic manufacturing，greatly improved information transmission and logistics efficiency，Data elements bonus、Geographical Gathering of upstream and downstream related enterprises、eliminating backward production capacity, etc.，reduced the cost and transportation cost of the productive investment in the basic manufacturing industry，Improving the potential of its external circulation internalization。(2) There is still a gap between China's high -end technology research and development and developed countries，But thanks to the unique advantage of the socialist system，Be able to focus on resources of all parties to promote key core technologies to achieve major breakthroughs，Makes high -tech manufacturing's external circulation internalization potential to fluctuate and rise。(3) China arable land、The proportion of the world of freshwater resources is only about one -third of the proportion of labor，and the world's proportion of petroleum resources is not yet one -tenth of the proportion of labor force，Need to import a large number of primary products to alleviate the constraints of the development of the shortage，But the primary product is due to its product characteristics and regional characteristics，It is difficult to make up with technical progress，Risks that are easily interrupted by external supply chains，Therefore, the lowest potential of external circulation is the lowest，and the fluctuations are large but there is no rise in rise。

　　Promoting the actual significance of the internalization of external circulation

From the perspective of domestic situation，bet365 live casino games China's promotion of external circulation internalization can help coordinate and promote the coordinated development of higher quality regions and the construction of high standard market systems，Implement the new development concept。Since the founding of New China，China's economy shows obvious non -equilibrium in region and space，uneven problems such as east -west imbalance and North and South gaps are becoming a barrier to fully release the demand for domestic market。Promote the internalization of external circulation，First, it can reduce and reduce the market segmentation caused by geographical barriers and administrative barriers，Based on resource advantages and industrial associations and industrial structure，Strengthening the coordination between the functionality complement of the urban agglomeration and the growth pole，Effectively match the professionalization of urban functions and factor endowment，Better practice innovation、Coordination、Concepts of openness and sharing，Establish high efficiency、High -quality、High -level market，Ensure the security and stability of the supply chain of the industrial chain; the second is to accelerate the unified openness、Construction of high -standard market system with an orderly competition，Promote the orderly transfer of various industries in China，Optimize the layout of the regional industrial chain，At the same time, the focus of economic construction is gradually shifted from coast to inland depth，Promote economic coordinated development in the central and western regions; the third is to implement the concept of "green water and green mountains is the golden mountains and silver mountains"，Putting ecological construction in the same important position as economic construction，Multiple measures and help the realization value of ecological products、preservation value -added，to ensure the effective construction of the new development pattern。

From the perspective of international situation，bet365 live casino games China's promotion of external circulation internalization helps to reconstruct the global value chain division，Revisiting Global Economic and Trade Rules，Lead the reform and construction bet365 best casino games of the global governance system。Construction of a new development pattern requires Unicom's domestic and international dual cycles，It is necessary to face the two major challenges of the value chain reconstruction and the reconstruction of international economic order。China's promotion of external circulation internalization can help traction and supply -side structural reform through demand.、Breaking the elemental disorder、Technology self -reliance and other measures，Open the blockage point of the domestic value chain，and assume the social responsibility of a large country in responsible development，Actively open up the blocking point on the international supply chain，firmly unswervingly promote high levels of opening to the outside world，and then one with other developing countries，Reshape the global value chain division system，Promoting economic globalization is more open、tolerance、British、Balance、Development of a win -win direction。The international economic and trade rules have undergone profound changes after the international financial crisis，The global governance system with extensive tolerance is gradually transforming into a regional trade rules with strong exclusion，And the new trade rules are still being established。Based on developing countries、Emerging market countries、Responsible big country、Multi -identity of a socialist modern country，China's promotion of external circulation internalization can help build a global governance system that co -build and share and share，In participating in global governance, fighting for more discourse and initiative for developing countries，Then promote the construction of a community of human destiny and new international relations。
