The Fifth Plenary Session of the 19th Central Committee of the Party pointed out that "promoting domestic and international dual cycles"，Accelerate the formation of large domestic cycles as the main body、The new development pattern of domestic and international dual cycles promotes each other is an objective requirement for the development of China's economic scale to a certain stage。Theoretical research of space economics has been indicated，Compared to geographical location、Natural factors such as natural resources，The increasing scale of rewards formed by the local market effect is an important day -to -day power that promotes the agglomeration of economic space。As a big country with a large -scale market advantage，Construction with a large domestic cycle as the main body、The new development pattern of domestic and international dual cycles promotes each other to form a new direction for the formation of China's regional economic growth.。

　　Bet365 lotto review

For more than 40 years of reform and opening up，The international cycle provides huge kinetic energy for China's regional economic growth，It played an important role at different stages of reform and opening up。Between 1978 and 2000，China's use elements cost comparative advantage implemented export -oriented strategies，First start from the economically developed areas，Gradually expand to nationwide，Through the development of processing trade、Introducing foreign investment and other methods to participate in international large cycles，The regional economy has grown rapidly。From 2001, China joined the WTO to the 2008 global financial crisis，Domestic different regions in China By comprehensively participating in the global value chain division of the global Bet365 lotto review value chain with the medium -quality trade as the core，Participating in the international cycle also supports China's regional economy into the fastest cycle of growth since the reform and opening up。After 2008，Affected by the negative impact of the global financial crisis and the conversion of China's economic development stage，The promotion role of international large cycle on regional economic growth has begun to gradually fall from the peak of the previous stage。At the same time，With the continuous improvement of China's economic development level，I am in technology innovation、The new competitive advantage formed in areas such as market size has made the role of domestic large cycles in regional economic growth continuously increased，In recent years, the trend of against globalization has intensified、The external environment changes such as the rising of trade protectionism further accelerate this process。

　　International Large Cycle Facing a new situation

Current，International large cycle drives China's regional economic growth is facing increasingly stringent constraints。

First, the resource constraints are constantly tightening。For a long time，Rich and cheap labor is an important source of the cost advantage of elements in the international cycle in China，But in recent years，Labor cost advantage is constantly declining。2019 China ’s 60 -year -old and above population accounts for 18.1%，The degree of aging population is continuously deepened，Labor supply has crossed the "Lewisfall"，Labor cost advantage is constantly losing。

Second, the environmental constraint is increasingly strengthened。The international industrial transfer with foreign direct investment as the core is China's participation in the international large cycle、Important kinetic energy that drives domestic regional economic growth。Existing research indicates，Developing countries participating in the lower environmental regulatory intensity in the international bet365 live casino games cycle division of labor will lead to "pollution and evacuation effect"，It is shifted to develop countries to develop countries。But in the background of green development，China has developed stricter environmental regulation standards for international industrial transfer，At the cost of sacrificing the ecological environment、The practice of attracting foreign direct investment without screening to drive regional economic growth has become a past。

Third, the importance of economic security constraints is prominent。As a developing emerging country，China ’s long -term excessive relying on the international large -cycle export -oriented strategy is very easy to cause trade friction，This also makes my country's development external environment facing new changes。More importantly，Due to developing countries in the process of participating in the division of international cycles, it is often easy to fall into the "low -end lock" trap，By imitation、Technology overflow, etc. It is difficult to effectively reduce the gap between China and developed countries in original innovation capabilities，It is more difficult to solve the key technical problems of China's urgent "card neck"。Especially since Sino -US trade friction，The United States "disconnect" for China in key technical fields such as China，and the unique toughness of China's economic growth since the epidemic of new crown pneumonia，Let us deeply realize that in the cruel international competition, relying on the external needs and technology of only international cycle，It is impossible to solve China's regional economic growth in sustainability、Strict challenges encountered in quality and other aspects，It is difficult to guarantee economic security。

　　Convert regional economic growth momentum

It can be said，The stricter constraints faced by China's economic development have made the international cycle increasingly obvious in promoting the economic growth of China's regional Bet365 app download regional，Optimizing the new momentum of regional economic growth is the general trend。During the kinetic energy conversion process of switching from international cycle to domestic large cycle leading driver，Need to be alert to new problems that occur in regional economic growth in China。

The first is the steady conversion problem of the economic growth momentum of many exterior areas。China ’s overall foreign trade dependence in 2019 is about 32%，Shanghai、Beijing、Guangdong、Tianjin、Foreign trade dependence of foreign trade in eastern China such as Zhejiang and Jiangsu is more than 40%or more; Dongguan、Suzhou、Shenzhen、The dependence of foreign trade in cities such as Xiamen still exceeds 80%。How to transition steadily to a new stage dominated by the domestic large cycle，It is an important issue facing China's regional economic development。Especially under the two -way squeezing of the "high -end return" of developed countries and "mid -to -low -end diversion" in developing countries，Weaken foreign demand、Capital return leads to weakening international circulation capacity，Cultivating the new kinetic energy dominated by the large cycle of China is to maintain the stable development of the regional economy、An important prerequisite for alleviating regional economic operation risks。

Second, the imbalance of the imbalance of regional economic growth under the new development pattern of dual -cycle has complexity and diversity。Under the new development pattern，The role of scale factors in determining regional economic growth is increasingly important，Population between regions、The competition in stock resources such as industry will be more intense，High -quality resources and elements will further gather to a few developed areas，"Cumulative Causal Effect" on the basis of this will cause regional gap to expand risk。First，China's regional economy will bet365 best casino games present the overall pattern of bonuses and north and south gaps。Except for the existing things gap，Since the north is in natural geographical conditions、Disadvantages of the business environment and economic scale，The new development pattern will accelerate the south of China's economic focus，The gap between the North and South will be further widen，Like Northeast、Tianjin、Shandong and others in the northern region, which is in the critical period of economic growth, will face greater pressure。Next，Urban gap will replace urban and rural gaps into the main problem。In 2019，Has entered the middle and late stages of urbanization，The urban and rural gaps caused by urban and rural dual structures in the early stage of urbanization are narrowing。But the dividend of the surplus labor transfer of the countryside gradually disappears，Urban -driven momentum driven by urban and rural labor transfer is weakened，The requirements of unblocking domestic large cycles under the new development pattern will enhance the urbanization of the population flow driven by the city。The re -configuration of the space of the existing population will cause urban contraction and expansion in the Chinese urban system，Integrated the regional gap between the urban agglomeration and the non -urban group and the central city and the marginal cities in the city group，The expression of the regional gap will also be more diverse。

　　Based on the overall market size advantage

The key to reshaping China's regional economic growth momentum under the new development pattern is based on the oversized market size and technological innovation advantage formed in the domestic cycle，Provide new kinetic energy support for regional economic growth from the supply side and demand side，As a result, a high -level dynamic equilibrium promoted by domestic and international dual cycles。

First，China must make full use of the oversized market scale advantage to traction supply side structural reform。First, Bet365 app download use your own multi -level、Over large -scale domestic market optimization domestic industrial chain and value chain，Deepen the domestic regional division of labor，In the domestic industrial chain、The spatial reorganization of the value chain improves the stability and competitiveness of the industrial chain while，Promoting regional coordinated development。The second is to give full play to the large market size of innovation investment、The increasing effect of the scale of achievement and application of results，Innovative innovation of frontier leading technology，Promote the development of regional economic innovation drive。Third, the advantages of the diversified market demand of online and offline integration，Use new consumption format、New model promotes the rapid iteration of products and technical supply，Form more regional economic growth breakthrough points。

Next，China should actively use technological innovation advantages to enlarge domestic market demand。First, we must give full play to the big data、Cloud computing、Artificial Intelligence、A new round of technological innovation advantages in many areas of scientific and technological revolution in the Internet of Things，Constructing a new type of consumer ecosystem，To achieve precise matching of supply and demand，Digging the potential of the domestic market，Enhance the contribution of domestic demand in regional economic growth。The second is to use new technologies to build urban and rural integration、National Unified Domestic Unified Domestic Market，Accelerate the construction of new infrastructure，Reduce the cost of transaction between regions，Accelerate the integration process of the domestic market，Expand the depth and breadth of the domestic market。

Last，The most important institutional guarantee for reshaping the new economic growth of China's regional economic growth from supply and demand Bet365 app download is the advantage of a special system of socialist system with Chinese characteristics，By implementing active regional economic policies and institutional innovation and unblocked blocking points and obstructions，The smooth conversion of regional economic growth momentum。
