In different links of the value chain、Process、The new international division of labor and the domestic regional division of labor，The productive service industry is in the high -end value chain，The main momentum of economic growth of various countries and regions。Reasonable productive service industry spatial structure can guide regional resources reasonably，Promote regional economic growth and sustainable development，Realize dense and orderly、Balanced coordination、Reasonable spatial development pattern of division of labor。From a micro perspective，The division of labor system of the productive service industry is the space configuration of the industrial chain between cities and inside the city，So the optimization of its spatial structure，It can be promoted from the two levels of the urban area and the city.。

The space agglomeration of my country's productive service industry is upward，Especially information services、Technology Service、The features of the high -end productive service industry such as business services are more obvious。At present, the productive service industry is mainly concentrated in regional central cities，It is not obvious for the driving role of non -middle cities。2016，31 regional central city productive service industry employment number accounted for 52.1%，And the development gap between the development of the productive service industry in the central city and the non -central city is increasing。With the advancement of industrial structure adjustment，The tertiary industry in the central and western regions accounts for a significant increase in the country's share，Among them, the service industry in the Sichuan -Chongqing area is the fastest。

From the perspective of industry distribution，Information Service、Technology Service、The service radius of enterprises in the bet365 best casino games three knowledge -intensive industries of business services is continuously expanded，High degree of agglomeration in the industry，Regional division of labor mode meets the theoretical characteristics of the central ground，Show the level scale structure，Comparative advantages are mainly concentrated in a few cities。The services provided by the transportation industry and the financial service industry are close -type services，The service provision point must be as close to the service object as much as possible，Small service radius，Low cluster level，The regional division of labor is relatively decentralized。Financial services as an important intermediate investment service，64%of cities in our country belong to the comparative advantage industry。With the rapid construction of my country's transportation network，The urban scope with comparative advantages with transportation services is expanded，and most of them are connected into films。

In the regional division of labor in the national productive service industry，Beijing is at the highest level of service center position，Information Service、Three -knowledge -intensive industry of science and technology services and business services are all in the country's cities，and have a comparative advantage。From the perspective of regional distribution，The productive service industry is in the center of the urban area to gather the situation，Among them, Beijing -Tianjin -Hebei presence Beijing -centered strong single center division of labor，The Yangtze River Delta presents a single center division of labor centered on Shanghai，The Pearl River Delta is Guangzhou、Shenzhen is the division of labor in the center of the center。

　　Strengthen the division of labor collaboration between cities in the urban circle

During the development of the urban circle，Not only should we pay attention to its regional spatial structure、Grade scale structure and functional tissue structure is reasonable，It is also necessary，Fully considers the mutual matching of the productive service industry and the urban scale and development Bet365 app download stage，Differences in the radiation range of the productive service industry，to form a suitable in the urban circle、Middle、The development model of the coordinated development of small cities。

On the one hand，Super City、The development of the productive service industry of special large cities and large cities should be based on the diverse model，And assume the core energy level function of the agglomeration element and the core energy level that radiates to the surroundings。For various departments of the productive service industry，It is easier to achieve cross -industry knowledge overflow，Multiple productive service industries can gather together within a city。The departments of the productive service industry are gathered within the city，More complementary or competitive relationships，instead of upstream and downstream relationships，Suitable for gathering in the big city。For big cities，Large industrial scale，The industrial chain is relatively complete，It has a large total market demand for the productive service industry and diverse forms，Coupled with funds、Technology、Talent、Information such as information is relatively abundant，Therefore, it can meet and realize the diversified development of the productive service industry。Another，The economic development level of big cities is relatively high，The consumption level of residents is also relatively high and diverse，Multiple productive service industries gather in big cities，It can meet the diverse needs of residents。So，In the urban circle，Big cities shall take the joint gathering of multiple productive service industry departments to undertake service functions。At the same time，Due to some high -level productive service industries against labor、Capital and other input elements have higher demand，Only layout of developed central cities，and the surrounding small and medium cities also have intermediate demand for these advanced productive services，Therefore, the productive service industry of large cities should also assume the function of providing services to surrounding cities。

On the other hand，Middle、Do not blindly pursue the "large and complete" bet365 best casino games development model，It should be combined with urban elements endowment、The core needs of comparative advantages and leading industries，Focus on developing specialized productive services with distinctive characteristics，to promote the improvement of local industrial efficiency。Product service industry In addition to gathered in large cities，The demand for productive service industry within the manufacturing department within small and medium -sized cities，It will also attract certain productive service industry departments to gather around it。Although the productive service industry in the central city also has service functions for the manufacturing of small and medium -sized cities，But due to the existence of space distance，These service functions do not meet all service needs of small and medium -sized cities manufacturing，Especially those functions that require "face -to -face" services，For example, business services and transportation services。So，supporting industry as a manufacturing industry，Product service industry according to the intermediate investment demand of the local manufacturing industry，Gathering phenomena will also appear within small and medium -sized cities。Small and medium -sized cities in formulating the industrial development plan of the productive service industry，Based on the comparative advantage of the industrial development of the region，Selective development of third -party logistics、E -commerce、Service outsourcing and other productive service functions，Building a characteristic brand of urban economic characteristics with professional development。

　　Reasonable arrangement of the development order and space layout of the internal industrial industry in the city

During the development process，Most cities in my country focus on the development of industrialization and ignore the development of the productive service industry，After the industrialization process is in the middle and late stages，Starting gradually paying attention to the development of the productive service industry，Transition from "Industrial Economy" to "Service Economy"。In this industrial development path，The industrial space layout of the city has bet365 best casino games begun to develop around the manufacturing department，When the development of the productive service industry is valued，The "extrusion effect" of the productive service industry and manufacturing industry in urban space，As a result, the problem of coordinating layout of the two industrial departments。

Product service industry tends to gather towards the city，But this does not mean that any city is suitable for developing productive service industries。Although the "retreat of two -in -three" policy adopted today is reasonable，but not applicable to every city。The motivation for urban development and evolution must have a certain industrial background basis，Many cities in my country are still in the stage of industrialization，The proportion of the service industry has increased，But the role of driving the city is still far less than manufacturing。For example, 2016，my country 297 prefecture -level and above cities，The proportion of the tertiary industry of only 128 cities accounted for GDP more than the proportion of the second industry，Other 169 cities are still in the development stage dominated by the second industry。And the agglomeration of the productive service industry in cities depends to a large extent on the optimization and upgrade of the manufacturing industry's industrial structure，closely related to the city's manufacturing industry structure。In the manufacturing development stage mainly based on labor -dense type，The role of productive service industry is difficult to reflect。In the capital -intensive or technical dense manufacturing industry，The role of the productive service industry is obvious。So，Cities at all levels should be based on the comparative advantage of the industrial development of the region，Combined with its urban development stage，It is determined that the development of the productive service industry leads the space gathering of the manufacturing industry，Still the development of manufacturing industry drives the productive service industry to gather，So reasonable arrangement of industrial development priority，Strengthening coordinated positioning benefits。

During the industrial space layout of the city，The "complementary effects" bet365 Play online games and "extrusion effects" of productive service and manufacturing coexist，To achieve the optimization layout of urban industrial space，You need to try to enhance the "complementary effect" between the productive service industry and the manufacturing industry，At the same time weaken the "extrusion effect" between the two as much as possible。Product service and manufacturing industry tend to be distributed by the "center -periphery" as a whole，The productive service industry tends to lay out in the city center，The manufacturing industry is deployed in the periphery of the city。From the perspective of the subdivision industry，Knowledge -intensive productive service industry departments have a strong demand for neighboring manufacturing layouts，Capital -intensive and technical -intensive manufacturing departments tend to be adjacent to the space in the space。Cities at all levels can formulate corresponding industrial guidance policies，Guide the reasonable industrial space layout within the city，Therefore, the coordinated development benefits between the productive service industry and the manufacturing industry，Realizing coordinated development。

In short，Under the background of the country's increasing importance to the development of productive service industry，cities at all levels have increased their investment in the development of productive service industry，But it is prone to repeated construction and other problems when lacking the top -level planning。So，The country's regional industrial development policy should further strengthen the coordination and close cooperation of industrial and space，Scientific guidance of the development of the productive service industry in different scale cities，Further refine and clarify the development model and key development direction of the productive service industry at the urban level，Fully docking the division of labor and space collaboration，To better realize the coordinated development of the productive service industry in the region。
