The development level of the service sector is an important symbol to measure the economic development level of a country and a region. General Secretary Xi Jinping out: "Build a new system of high-quality and efficient service industry, and promote the deep integration of modern service industry with advanced manufacturing industry and modern agriculture." The Fourthenary Session of the 20th Central Committee of the Communist Party of China "Proposal" put forward "Implementing the service industry expansion capability and quality improvement action" and made strategic deployment to promote high-quality and efficient development of the service industry. In today's era, scientific and technological innovation is an important engine for the development of human, accelerating scientific and technological innovation is a realistic need to promote high-quality development, and will also provide an important support for the expansion and quality improvement of the service industry. implement the decision-making and deployment of the Party Central Committee, we should deeply grasp the requirements of the times to build a new system of high-quality and efficient service industry, promote the expansion and quality improvement of the service industry through scientific and technological innovation.

As an important part of the national economy, the development of the service sector can not only provide support for economic growth and improvement of peoples livelihood, but also help deepen the specialized division of labor in society, increase effective supply, and form new economic growth points. At the same time, the service sector also the characteristics of low resource consumption and low pollution emission. The deep integration of modern service industry with advanced manufacturing industry and modern agriculture can ease the pressure on energy resources and environment, improve the quality and efficiency of economic growth. Since the 18th National Congress of the Communist Party of China, under the leadership of the Party Central Committee with Comrade Xiping at its core, China's service sector has achieved remarkable results, with the added value increasing from 24.5 trillion yuan in 2012 to76.6 trillion yuan in 2024, contributing 56.2% to the national economic growth in 2024; In 204, the proportion of employment personnel in the service sector in the total employment personnel in the country reached 48.8%, and the service sector became the "main channel for absorbing social employment, especially the emerging platform economy, sharing economy and other new formats, which created many employment positions. At the same time, we need to see that compared the requirements of high-quality development, there are still some problems in the development of China's service sector, such as insufficient supply of high-quality services, especially professional production and high-quality living services, and the need to further enhance innovation capability. Implementing the service sector expansion capacity and quality improvement action, focusing on solving the difficulties and challenges by the development of the service sector through deepening reform, promoting innovation and other measures, is conducive to promoting high-quality and efficient development of the service sector

For instance, the extension of productive service sector towards specialization and high-end value chain, and living service sector towards quality, diversification and convenience development are becoming the important directions of service industry development. Supporting the wide application of digital technology and rich application scenarios can optimize the allocation of service, expand the boundaries of service industry development, and make up for the shortcomings in high-quality service supply. Especially, big data, cloud computing, Internet of Things and other new technologies have given birth to new service models such as online education, remote medical treatment, intelligent health preservation and smart logistics, extending services to regions and fields that were difficult to cover in past, and expanding the scale and capacity of the service market. For another example, efficiency and quality are the core competitiveness of the service industry. The comprehensive use of artificial intelligence prediction information platform construction and other means, relying on intelligent algorithms, block chains and other technologies to systematically reengineer the service process, can strengthen the precise real-time matching of supply and market demand, and effectively improve the efficiency of the whole chain operation. To expand and improve the service industry with the promotion of scientific and technological innovation, we can focus on following aspects.
Improve the ability of key core technology supply. Whether it is to accelerate the development of productive service industry to meet the needs of building a modern industrial system the needs of transformation and upgrading of various industries, or to improve the supply capacity and level of living service industry to meet the growing needs of the people for a better life, it inseparable from the firm grasp of key core technologies, and to build a solid foundation for high-quality and efficient development of the service industry. To this end, we should full play to the advantages of the new national governance system, strengthen technology innovation and application, create a number of key public technology platforms oriented to the service field, and master the controllability of core technology and development path. Deploy new infrastructure proactively, build data centers and computing centers orderly, promote the construction of high-quality data sets, and attention to the effective sinking to service industry SMEs and county and township areas, so as to effectively open up the "last mile" of service innovation. Implement the "Art Intelligence  " initiative actively, develop artificial intelligence services, data services, intelligent computing services and other information technology services, promote the digitalization of service industry, and empower the overall upgrading service industry.
The application scenario is the bridge connecting technology and industry, research and development and the market, and plays an important role in promoting the-scale commercial application of new technologies and new products. It is necessary to give full play to the advantages of China's super large-scale market and rich application scenarios, build effective path of "technological breakthroughs-scene verification-industrial application-system upgrade", and transform technological potential into real power to promote the expansion and quality improvement of the industry. For example, opening up application scenarios in the fields of smart cities, government services, public transport, and medical and health can provide a key platform for the deep integration scientific and technological innovation and industrial innovation in the service field. It is necessary to use scenario requirements to lead technological research and development and model innovation, focus on the pain points and difficulties the development of the service industry, and guide social innovative forces to jointly attack and provide precise and efficient solutions.
Focus on enhancing the innovation capability of market entities. The capability of the service industry is concentrated on the innovation and entrepreneurship capability and vitality of service industry market entities. To expand the capacity and quality of the service industry through scientific technological innovation, it is necessary to cultivate and develop a number of market entities with innovation capability and vitality. It is necessary to select and cultivate a number of leading enterprises with international and influence in key fields of the service industry, strengthen a number of leading service industry enterprises and platform-based enterprises, increase the cultivation of service industry SMEs, and promote all of market entities to continuously discover new technological growth points and industry burst points in the process of participating in the allocation and development of scenario resources in a fair and efficient manner, and the service industry to improve the innovation capability of the whole industry chain, expand the market space.
