Against the backdrop of profound changes in the global economic landscape, expanding domestic demand has become a key strategy for China's sustainable economic development. At present, China is facing the urgent issue of transforming the power industry of economic growth. The real estate and export industries, which used to drive China's super high economic growth, have significantly weakened their momentum. In the next step, modern productive service industry is most likely to become the new power industry sector in the realization of Chinese path to modernization. As an important component of the modern industrial system, the development level and quality of productive service industry have become important indicators for measuring the international competitiveness of a country or a city. In addition, the productive service industry can effectively enhance the production efficiency and competitiveness of the manufacturing industry by providing specialized services. At the same time, through service innovation and consumption guidance, it can create new market demand, and activate the expansion of domestic demand scale as well as structural upgrading. Therefore, promoting the modern productive service industry to become a new power industry is of great significance for achieving sustainable economic development in China during the 15th Five Year Plan period.
