Product service industry refers to an industry that provides guarantee services for production activities，In essence, it is an extension of the upstream and downstream production activities，Including professional services、Information and intermediary services、Financial insurance services and trade -related services。Product service industry for continuity to maintain the industrial production process、Promoting industrial technological progress and industrial upgrading，and improving production efficiency is important。The development of new generation information technology and digital economy，To a certain extent, the spatial agglomeration characteristics of the productive service industry and manufacturing industry，Coordinated gathering of manufacturing and productive service industries began to separate，Especially R & D design、Technical Services、Consultation、Advertising and other productive services have begun to become an important support for economic development。Not only that，The penetration of the digital economy will enhance the market penetration of the productive service industry，Break through the space -time boundary of the service market to a greater extent，more extensive serving bet365 best casino games other departments of the national economy。Technology's development also makes the productive service industry dependence on knowledge technology and human capital，IoT、Big Data、Artificial intelligence, while significantly reduced material costs，Generate stronger innovation needs。It can be said，Innovation is the essence of the professional service industry。

Product service industry is the product of deepening industrial division of labor，Forms a cooperative symbiotic relationship with the manufacturing industry。But，When the productive service industry develops to a certain stage，The importance of its supply quality to the development of the industry is increasingly prominent，Product service and manufacturing、Structural issues such as the configuration competition of production factors may also occur between agricultural and other service industries。Urcense of supply and demand to solve the development of productive service industry，The degree of professionalism that needs to be increased。The modern industrial system is based on the new generation of information technology，Digitalized、Intelligent technology meets consumers' personalization、Customized requirements，The result of innovation development。The more high -value creation activities under the modern industrial system，The greater the professional needs of the productive service industry。Innovation is exactly the core movement of the professional service industry，The professional service industry driven by innovation will further support the manufacturing industry、High -quality development of agriculture and other service industries，Create a new advantage of competition for the modern industrial system。

　The degree of professionalism needs to be improved

In -depth integration of manufacturing and advanced service industries into an important support for the transformation and upgrading of the manufacturing and service industry，Vigorously developing the agricultural productive service industry has gradually become a key part of promoting high -quality agricultural development。It can be said，Professional level of productive service industry is closely related to the development level of modern industries and modernization。From the perspective of production，Products or services of the productive service industry are mostly in the middle investment，restricts the technical content and production efficiency of the final product during the production process。R & D and technology services、Design Service、The degree of professionalization of the productive service industry such as information software services even bet365 best casino games determines the company's long -term sustainable development level。

Not only that，The degree of professionalization of the productive service industry is also the key factor of the transformation and upgrading of a country's industrial chain supply chain。For a long time，Chinese enterprises through processing、assembly and other forms participate in the global industrial chain supply chain，The development goals of globalization and industrialization have been successfully achieved。But as the economy and society entered a new stage of development，High -end upgrade to the industrial chain supply chain is inevitable，and improve the professional level of the productive service industry，It is important to actively promote the in -depth integration of the productive service industry and the manufacturing industry。Dependence R & D、Design、Advertising、Breakthrough and transformation in the production service industry related fields such as marketing and after -sales service，So as to achieve my country's status on the global industrial chain supply chain rising。

Professional service industry is service content、Comprehensive embodiment of service quality and service innovation。On the one hand，Professionalization of productive service industry is the transformation from the productive service industry from "passive" to "active" cross -border service，Release requirements for guiding other related industries、It has an important role in promoting corporate value chain climbing and realizing service -oriented production upgrades。On the other hand，Specialization of productive service industry requirements to provide services with higher degree of matching with diversified demand，It is a differentiated and innovative service based on service standardization，It helps to realize the layers of the same service content。

Research Discovery，my country's information technology service、Finance、Logistics、R & D design and other productive service industries present a rapid growth momentum，Professional level has improved，But the development level of my country's productive service industry is generally not enough to support the construction of the modern industrial system。First, the internal industrial structure of the productive service industry is imbalance，High -end productive service industry accounts for too low。and transportation、Ware、Finance、Wholesale and retail industry compare，2020 my country R & D and Design、Technical Services、Information services and other industries accounted for less than 35%，and the productive service industry in developed countries accounts for bet365 Play online games about 70%。Not only that，Product service industry supply and demand shows low -end supply excess supply、Significant structural mismatch with insufficient high -end supply，Unde -sed problems of the internal industrial structure of the productive service industry in my country。Second, the productive service industry and agriculture、Low fusion efficiency of manufacturing and other service industries。Application of the output database (WIOD) input output table，After calculating the efficiency of the integration of the productive service industry and other industries, it is found，The integration efficiency of my country's productive service industry and manufacturing (0.669) is far lower than that of the United States (2.862)、Germany (3.388)、Japan (1.679) and other developed countries，The integration efficiency of the integration efficiency of agriculture (0.355) and other service industries (0.967) is also not high。Third, the productivity of the productive service industry is urgently needed to increase。The application contains negative output SBM -DEA models to further calculates the entire factor productivity of my country's productive service industry，Even under the influence of environmental factors，The productivity of the productive service industry is only 1.9%，There is a large gap with the national green full factor productivity (6.46%)，Compared with the manufacturing green full element productivity (6.08%)，The gap is equally significant。This can be seen，The degree of professionalization of my country's productive service industry needs to be improved urgently。

　　Help the construction of the modern industrial system

The modern industrial system contains modern agriculture、The three major industrial systems of modern manufacturing and modern service industry。Enhance industrial innovation ability、Improve the efficiency of factor configuration and full factor productivity、Persist in the ecological bottom line that is constantly lifting，conforms to digitalization、Intelligent、The integrated development of industrial integration of service trends is the core essence of the modern industrial system。Professionalization of productive service industry can effectively link and serve the entire process of constructing the construction of modern industrial system，Precisely matching productive service content and level of product development of various industries，Improve the integration efficiency of the industry，to promote the construction of the modern industrial system。

First, optimize the internal structure of the productive service industry。At present, priority development is high、High -end productive service industry with strong industrial drive has reached consensus in all walks of life。For this，To actively improve bet365 Play online games industrial design、Industrial Internet Access and related services、R & D intermediary service、Information Technology Service、The proportion of high -end productive services such as the Internet of Things technical services。Especially with quality as the core，Supply quality of the productive service industry，Taking human capital as the core of quality improvement，Fully attach great importance to the personality of the service and demand market，To better promote the professional development of the education and training industry as a human capital reservoir。At the same time，To prevent some cities and regions in the development of low -level duplication due to comparison in the development of the productive service industry、Model follow the trend and other problems。

Second, the high -quality development of the productive service industry is innovatively driven by innovation，Modern industrial system that promotes the formation of an open innovation network。Open Innovation Network requires the productive service industry to be in an innovation basis、Innovative content、Four aspects of institutional environment and talent training to support strong support。Standardization is the basis of modern industries，Testing certification in the productive service industry is the key to ensuring the standardization of industrial development，The standardization of the productive service industry is promoted as the premise of innovation -driven。Taking system reform as a breakthrough，Increase research and development、Technical transfer、Entrepreneurship incubation、Intellectual property、Science and Technology Consultation and other science and technology services，Promote the precise docking of the innovation chain and the industrial chain，Strengthen key core technology research and transformation of scientific and technological achievements。Actively encourage the technological innovation of the productive service industry，For the Internet of Things、Big Data、Cloud computing、A new generation of information technology such as artificial intelligence provides more scenarios in the application of productive service industry，Create a more relaxed system and policy environment for productive service companies。Start with the basic work of education and talent training，Strengthen design、Education and talent training model changes in the fields of cultural creativity，Increase the training of skill -based application type talents，Bias of the supply of talent supply and industrial demand。

Third, to promote the professionalization of the productive service industry with the help bet365 best casino games of digital platforms，Give full play to the active network effect of the productive service industry。Digital platforms can minimize information asymmetry of the productive service industry，Improve the transparency and integrity of the supply and demand parties，So as to enhance the system integration and development capabilities of upstream and downstream enterprises and industries。Not only that，Digital platforms are likely to break through the space -time border of the productive service industry，Enhance the competition of market entities，Forging enterprise market competitiveness，Give full use of the external nature of the network at the same time。Common service needs around the development of modern industries，Cultivate a batch of strategic consultation、Management Optimization、Solution Innovation、Comprehensive service platform for digital capacity building，Promote the coordinated research and development between platforms、Resource sharing and results promotion and application。Perfect the open source design with the systemic thinking、Software Development、Information、E -commerce、Finance、Technology transfer and other platforms are the productive service industry platform economic system，Specialization and intensive development of the productive service industry。

Fourth is to deepen the supply -side structural reform of the productive service industry，Improve industrial integration efficiency，To build a modern industrial system。On the one hand，To identify agriculture、Manufacturing、Service needs for the service industry，Implementation of differentiation and precision service supply，Guide the reasonable configuration of the production factors，Optimized product supply structure，Cracking supply -side structural mismatch problems。On the other hand，To capture new service requirements in the construction of the modern industrial system，Guidance Technology、Knowledge、Production factors such as human capital and other production factors are weak in the development of productive service industry and even gathered in the blank field。Such as optimizing the technology of green manufacturing、craft、Process、Management，Accelerate the promotion of breeding、Agricultural technology transfer、Modern agricultural productive services such as farmers training，To truly make the productive service industry a adhesive for industrial integration and development，Help the construction of the modern industrial system。
