The essence of regional economic integration is through market integration、Industry fusion、Policy integration and other means，Reduce transaction costs，Gradually cancel various economic and non -economic barriers，Improve factor flow and product trade freedom，To achieve the optimized allocation of resources。According to regional economics theory，There are two forms of division between cities。First, competition between the horizontal urban government，It is manifested in the lack of division of labor in core cities and other cities，and disorderly competition between non -core cities。In the Yangtze River Delta area，Shanghai has a recognized core city status，Other cities recognize and take the initiative to accept Shanghai Economic Radiation，Shanghai and other cities have formed an industrial division of labor system mainly based on vertical division of labor。Despite this，Shanghai still exists in the manufacturing industry and other regulations with Jiangsu and Zhejiang，The dispute between the automotive industry in Jiangsu and Shanghai is an obvious example.，Competition between adjacent cities around Shanghai is more obvious，For example, in attracting investment、Industrial structure、Infrastructure、Environmental coordination and other aspects。Second is cities competition between the relationship between vertical power。Due to the division of rights between the government，County Reform City、Municipal Administrative County and other urban management systems，There is also a struggle for control of resource control between Bet365 app download the urban government with administrative affiliation，and the uncoordinated infrastructure supporting。The disorderly competition between cities has split the division of labor networks between the economic market and the city in the urban circle，Caused lack of coordination between cities，So it is difficult to form a unified large market in the region。

Local protection and market segmentation brings huge trading costs，It is difficult to achieve effective allocation of resources in the region，It is mainly reflected in the following aspects。

The first is the flow of local protection cutting elements。When the government is the leader and promoter of the local economic development，Prevent local resource outflow and outflow of local products are usually decision -making behaviors for local governments。​​This not only directly harms consumer interests，and hinder the improvement of the efficiency of resource space allocation，huge losses caused by economic efficiency in various places。Market integration By eliminating the economic and non -economic barriers of the flow of various commodities and factors in the region，Promoting the formation of a large market unified market，Therefore, the optimization and efficiency improvement of the internal resource allocation、The refinement and reasonable layout of the industrial division of labor and the effective exertion of the regional scale economy provide conditions，and finally realize regional integrated development。Current，In the commodity market，Some tobacco and alcohol in the Yangtze River Delta area、Car、High tax rates such as home appliances setting market barriers and formulating discriminatory regulations have not been eradicated; in the production factor market，An important transportation channel bet365 Play online games in the province (cities) in the area is not allowed to pass the traffic or set up charging levels in foreign vehicles; most property trading markets are "local assets、Local Assets reception "，Humans who cause property rights transactions are geographical splitting, etc.。

Second is the waste of industrial homogeneous and excessive competition that leads to waste。With the rapid development of high -speed rail and the Internet，The Yangtze River Delta enters the era of depth of the same urbanization，But there is no differentiated advantage in the area。Computer、Communication and other electronic equipment manufacturing、Electric machinery and equipment manufacturing、Chemical raw materials and chemical products manufacturing、Automobile manufacturing and general equipment manufacturing industries have become common advantage industries in all regions。Although the construction of the Yangtze River Delta Development Zone is to promote industrialization、An important platform for the rapid development of urbanization and opening to the outside world，But at the same time，Excessive number of various types of development areas、Unreasonable layout、Repeat construction at low levels、Malignant competition and other issues are more prominent，Unexpectedly need to introduce policies to coordinate and coordinate。As of 2018，46 provinces and cities of the Yangtze River Delta have been established for 146 national economic and technological development zones，Among them, there are 20 in Shanghai，There are 34，There are 71 in Jiangsu，There are 21 in Anhui。A large number of economic development zones bring duplicate and overlap in the industrial layout，Industrial homogeneous and excessive competition issues serious。

Third is to repeat the layout to give birth to an invalid configuration。Repeated layout here mainly refers to the duplicate Bet365 app download game provided by public items in the area。The construction of large public goods in the area can not only improve the urban investment environment，And its own economic function，It also makes it an important source of urban fiscal revenue。Due to the lack of regional reasonable planning and comprehensive coordination，Local governments in the development zone、All kinds of parks、Airport and other infrastructure exists in obvious repetitive construction，Especially for those public goods with strong overflowing regional public goods，Lack of overall planning plan、Each is politics，The result is repeatedly provided，This approach not only leads to unreasonable industrial layout，and cause serious waste of resources。Excessive provision of the port port of Yangtze River Delta is a typical case。More than 20 ports densely in the Yangtze River Delta area，Including Shanghai Port、Ningbo Beilun Port、Sham Shui Port, large and small Yangshan, etc.，and the cities along the river downstream of the Yangtze River are almost building ports，The severe excess of the port and dock fully reflects the structural contradictions in construction。This not only causes waste of strategic resources，It also objectively reduces the overall strength and comprehensive development potential of the region。

　　Establish a unified and open regional large market

Through effective industrial policies, you can correct some market failure，Promoting the improvement of resource allocation efficiency and optimization of industrial structure，Promote the development of high -tech industries。Under the new normal of China's economic development，There are many traditional industries due to history、The reasons for the technology and overcapacity，In this regard, China proposed to achieve bet365 live casino games an optimization and upgrade of industrial structure through the conversion of new and old kinetic energy，This requires to promote the market to solve some key technical problems through effective industrial policies，To ensure the continuous and stable growth of the economy and high -quality development。

The game made by the local government due to their own position，The policy formulation requires the use of full and effective decision -making information and scientific methods to demonstrate and predict。Therefore，The formulation of industrial policy is jointly influenced by a series of subjective factors and objective factors。Coordinated governance is an effective way to solve subjective problems and deal with objective challenges。

In the background of integrated development，Optimizing integration of regional advantageous industries is the focus of implementation of regional industry integration。According to the natural resource endowment of natural resources in various regions、Infrastructure、Advantages of industrial foundation and market conditions，Select industries with appropriate scale and development potential for key resource integration。But，Resources under local protection and market division of non -free flow are an important manifestation of uncoordinated regional economy，This seriously restricts products in the region、Talent、Corporate free flow，Makes resources unable to flow smoothly，seriously hindered the coordinated development of regional industries。Therefore，To coordinate regional relations、Realize collective interests，It is necessary to break the administrative division through the reform of the administrative system，Establish a unified and open regional large market，Provide a better industrial competitive environment。

bet365 best casino games Although the long triangle commodity market integrated progress is fast，But because the admission mechanism of the product sales market has not been unified，There are still many protection of non -trade barriers，If the license system and government procurement regulations in government procurement, etc.。Regional collaborative governance is market principle、Cooperation between public institutions and non -public institutions in common interests，By constructing a unified market for the area，It can correct the government's improper intervention in the market to a certain extent，Give play to the decisive role of the market in the allocation of resource allocation，Use competition policy to correct market forces, especially administrative monopoly forces，Integration of resources of the industry、Competitive cooperation and coordinated development。The government is the main motivation for promoting regional cooperation and coordination，You need to formulate a unified market standard system，The current regional competition lacks bottom line constraints、Unified market standard system and market environment that can promote free flow of factor。

other，Under the perspective of collaborative governance perspective, the development policy of the long triangle industry integrated triangle industry should also include the following five aspects: First, strengthen the planning of industrial development，Optimize the industrial space layout of the Yangtze River Delta; the second is to build a regional industrial linkage mechanism，Promote higher -quality integrated development; third, give full play to regional industrial advantages，Improve the industrial energy level of the international metropolis; fourth, integrate regional cultural tourism resources，Open the unified bet365 live casino games market for the cultural tourism industry; the fifth is to improve the coordination of industrial policies in various places，Improve the coordinated development mechanism of regional cooperation。
