Does Digital Technology Promote the Integration of Manufacturing and Services?

With the rapid development of digital technology and its application in various fields, various new models and new business formats are emerging, bringing subversive changes to industrial development. The same is true for manufacturing and service industries. The scope of their industries is expanding, the industrial characteristics are becoming more and more similar, the boundaries between them are becoming more and more blurred, and the trend of integrated development of the two industries is becoming more and more obvious. An in-depth study of the impact of digital technology on the integrated development of manufacturing industry and service industry is not only conducive to clarify the internal mechanism of digital technology on industry development, but also provide useful theoretical support for promoting industrial upgrading and realizing high-quality economic development.#br#Therefore, this paper will focus on the relationship between digital technology and the integration of the two industries, and explore the fundamental problem of what mechanism digital technology mainly affects the integration of manufacturing industry and service industry. According to theoretical analysis, we have assumed that there are three main mechanism paths to influence industrial integration.(1) As a general-purpose technological innovation, digital technology continues to penetrate into various industrial fields, which can promote the better connection of various products and services, reduce the technical threshold between industries, and break through the technical barriers in the process of industrial integration. (2) Emerging digital technologies such as cloud computing and big data provide an optimization path for matching problems in the market. Manufacturers reduce the cost of information search and matching through digital platforms, thus promoting industrial integration. (3) The application and popularization of digital technology in production and life has greatly improved the convenience of information acquisition and consumption process. Diversified and personalized consumer demand has been continuously stimulated, which has given birth to a large number of emerging industries and formats, and expanded the market demand boundary.#br#Based on the above theoretical mechanism, the research measures the development level of digital technology and the degree of industrial integration of 214 cities in China from 2012 to 2019, empirically tests the impact of digital technology on the development of industrial integration by using econometric model, and makes an in-depth study on the specific impact mechanism and effect. The main conclusions of the paper are as follows: (1) Digital technology plays an "adhesive" role between manufacturing and service industries, and its development can significantly promote the integration of manufacturing and service industries. Through "technology" and "platform", digital technology can break the barriers of production and realize multi-channel information connectivity, so that the integration of manufacturing and service industries becomes efficient. (2) The impact of digital technology on the integrated development of manufacturing industry and service industry has regional heterogeneity. From the perspective of region, the positive effect intensity of digital technology on industrial integration has the characteristics of "northeast region > western region > Eastern Region > central region"; Compared with technology intensive areas, the development of digital technology will have a stronger positive impact on the integration of two industries in nontechnology intensive areas. (3) Technological innovation effect and expanding market demand are the main transmission mechanism of digital technology affecting the integrated development of manufacturing industry and service industry. The application of digital technology in production and operation can promote the continuous improvement of industrial technology level and innovation efficiency. The diffusion of digital technology among industries promotes the connection between upstream and downstream industries, thus promoting the development of industrial integration. In addition, the development of digital technology has brought the emergence of various application software and system platforms, greatly improved the convenience of information transmission and access. The personalized and diversified consumer demand of consumers is increasing and displayed. Enterprises try to improve their production and service supply capacity to meet the changes and expansion of market demand. Therefore, the manufacturing industry and service industry continue to integrate and develop.#br#The marginal contribution of this paper is mainly reflected in the following two aspects: firstly, combined with the characteristics of digital technology, this paper constructs a theoretical analysis framework from the perspective of the integration of manufacturing industry and service industry, clarifies the internal mechanism of the role of digital technology in the integration of manufacturing industry and service industry, deepens the understanding of industrial integration mechanism and regional heterogeneity, and develops the research of digital technology in industrial application,secondly, it comprehensively measures the level of digital technology and industrial integration from the urban level, comprehensively evaluates the role of digital technology in promoting the development of the integration of the two industries, improves the research content of digital technology in the field of industrial integration, provides useful theoretical support for promoting industrial upgrading and realizing high-quality economic development, and deepens the existing literature.#br#
