Accelerating the development of urban economic development is the realization of the high -quality development of my country's economy、The inevitable requirement of unblocked the national economic cycle。China's economy has shifted from a high -speed growth stage to a high -quality development stage，Is in a transformation method、Optimize the economic structure、The critical period of conversion growth momentum。bet365 live casino games Accelerate the development of urban economic，For the new development stage of science，Perform new development concepts，Accelerate the construction of a new development pattern，Realize economic circulation and unblocked industrial associations，Promoting high -quality economic development、It is significant to realize the healthy and stable operation of economic health and promote social stability and harmony。 

Accelerating the development of urban economic development is to promote domestic and international dual cycles、The inevitable requirements of deep participation in global competition。Speed ​​evolution without a large change in the world's century years，The global industrial chain supply chain faces impact due to non -economic factors，International Economy、Technology、Culture、Security、Politics and other patterns are all undergoing profound adjustments。The current international competition is also reflected in the competition between cities and urban areas。bet365 live casino games Accelerate the development of urban economic，It is conducive to the risks and challenges that may exist in the international environment，Improve international circulation quality and level，Expand my country's global industrial chain、Supply Chain、Influence in the Innovation Chain，Form new international cooperation and competition。 

Accelerating the development of urban economic development is in line with the wave of technological changes、The inevitable requirements of the era of digital economy。Technical change，Especially the mobile payment brought by the digital economy、Online appointment、Sharing travel and other new modes、The new format provides convenience for urban life，Artificial intelligence technology is a product、Process and business model innovation provides opportunities。At the same time，Technical changes may also exacerbate inequality within the city，Challenges to the tolerance development of the city。bet365 live casino games Accelerate the development of urban economic，It is helpful to give birth to more employment positions，Organic combination of promoting technological changes and employment of residents，Forms an effective urban economic system that has an effective response and stable and reliable urban economic system。 

　　Deep understanding of the sustainable development of the urban economy 

City is the main place for human activities，It is a collection of economy、Social and ecosystems integrated、Complex and open artificial giant system。my country's urban development is shifting from large -scale incremental construction to existing quality transformation and incremental structure adjustment，Facing the economic system that deeply affects urban development、The complexity of the social system and ecosystem，Promoting the sustainable development of urban economy becomes an inevitable choice。Sustainable development concept and systemic thinking have become the underlying thinking of understanding the sustainable development of the city economy。 

First，Deep understanding of the complexity of the urban economic system。bet365 best casino games Its complexity is mainly reflected in the two aspects of dynamic complexity and structural complexity。Dynamic complexity is mainly manifested as: continuation with time，Random disturbances with regular economic fluctuations and random disturbances caused the phenomenon of rising and falling in the process of economic development，The changes in external factors have an uncertainty on the impact of the economic system，Vague cause and effect caused by economic fluctuations，The laws and trends are difficult to predict。Economic uncertainty has become a major challenge facing the development of the global urban economic development。Structural complexity is mainly manifested as: at a certain point，The composition of the economic system has different rigidity，When resource endowment、Production structure、Infrastructure and upper buildings fail to change simultaneously，It will cause the economic structure to distort the economic structure brought by different changes。Urban economic structure adjustment ability is an important observation indicator for urban adaptation complexity。 

Next，Deep understanding of the complexity of the urban social system。Its complexity mainly contains social structural complexity and function differentiation complexity。With the expansion of the city's scale，Refining the division of industries and social labor helps to expand the scale of production and consumption，Continuous pressure on social functions and structures。Social function and structure involve multiple subsystems，If the existing order is unable to adapt to the hierarchical and ordering of the subsystem，It will make it increasingly difficult to collaborate on each component.，Extract the complexity of social structure。In the modern society of functional differentiation，Independent operation of each functional system depends on each other，It is a relationship for mutual service and support。The complexity brought by the internal system of the system，The only bet365 live casino games subsystems are constantly self -differentiation，This increases the complexity of the social system。The interaction between the complexity of the social system and the complexity of the economic system，higher requirements for the governance toughness of the city。 

Last，Deep understanding of the complexity of the urban ecosystem。Its complexity refers to the complexity of the ecosystem structure and function。The number of components of the ecosystem is huge，There are a lot of connections between the units，Any composition unit may exist in a variety of different states，The choice of the existence state is affected and restricted by other components in the system，This complicated feedback ring。Energy flow of the ecosystem、material cycle、Information transmission and other functions in the complex feedback system to realize the cycle，When the function of the ecosystem cannot be played normally under the interference of the outside world，It forms a damaged ecosystem or a degraded ecosystem。The urban economic and social development since "Human World" has made the symbiotic system of man and nature gradually be removed and collapsed，and then a severe challenge for the sustainable development of human beings。 

　　Enhance the motivation of urban development with new development concepts 

The goal of the sustainable development of urban economy is to build a city -centered city。General Secretary Xi Jinping proposed to firmly establish innovation、Coordination、Green、Open、Shared development concept，Based on China's national conditions、Consolidate the development concept of the times，Cracking the problem of urban development、Enhance the motivation of urban development、The advantage of the development of urban development is of great guidance significance。 

First, take the road of innovative guidance。City is not only a container for culture，More innovative container。Enter the stock adjustment stage in urban development，Innovation is the first motivation to lead urban development。Realize the high -quality bet365 live casino games development of urban economy，In response to the wave of technological changes, you need to take the road of innovative leadership。Urban development in the new era should be placed in the core position，Realization of technology、Talent、Collaborative linkage of the education system，It is to pay attention to the important role of talents in scientific and technological innovation，Rely on local advantages、Gathering innovative elements、Create urban innovation ecology，Breaking the mechanism of the system，Fully release people's innovation ability，Scientific and technological innovation help the sustainable development of the city economy。 

The second is the road to regional coordination。Focus on solving the problem of polarization effects in large cities and imbalance between urban development，Breaking the limitations of administrative division，Make full use of market means to promote the integrated process of urban agglomeration and urban circle。Adjustment of the equalization of infrastructure and the layout of public service space，Especially the cross -regional configuration of advanced production factors such as digital elements，Gradually reverse the area、The trend of the development gap between urban and rural development。Using county urban and towns as the starting point，Realize classification advance、Key support、Gathering Development，Efforts to form East、Middle、Promote from cities in the western region and large, medium and small cities、complementary advantages、New pattern of continuous development。 

Third, take the road of ecological efficiency。Ecological city、The concept of smart cities and tough cities is guided，Focus on solving the problem of the harmonious development of the complex system and nature of the city。Taking urban digital transformation as a means，Taking the "double carbon" goal as a breakthrough，Adjust the urban industrial structure and spatial structure as the opportunity，Promote bet365 Play online games the comprehensive transformation of urban economic and social development。Actively explore the new mode of development of urban space such as characteristic towns，Pay attention to production、Life、Ecological "Three Lives Fusion"，Fully realize "production、City、People、Wen "Four in one，Make the city a high -quality space for livable and livable and well -traveled。 

Fourth, take the road of openness and tolerance。From the perspective of urban agglomeration and urban circle, solve the problem of internal and external linkage，Then improve the open layout，It is necessary to enhance the level of city opening in all aspects。At the same time，Urban economic development also needs to pay attention to opening up，Create a diverse and tough urban governance system，Diversified symbiotic symbiotic symbolism that promotes different cultural backgrounds in the region，Create more development opportunities for special groups, especially vulnerable groups，Make big cities more temperature，Small cities are more energetic。 

Five is the road to cooperation and sharing。High gathering characteristics of the city provides necessary prerequisites for regional cooperation and sharing of public products，The negative externality brought by the height of the gathering also challenges social fairness and justice。Only guided by the concept of the people's city，Starting point and ending point with improving the well -being of the people，firmly grasp the value pursuit of social fairness and justice，can solve the problem of social fairness and justice in the "big city era"。Only constantly innovative institutional arrangements，Strengthen the construction of legal system，Improve the level of urban governance，can we effectively protect people's equal participation、The right to develop equal development，enable the majority of residents to enjoy more in the co -development and development of the city、satisfaction，Then enhance the motivation Bet365 app download of urban development，steadily moving towards the common prosperity。
