Digitalization is an important engine for China to promote high-quality development and enhance international influence. Combining the practical needs of digital economic model innovation，technological innovation and factor innovation，deeply integrating the whole process of digital governance into all aspects of economic development is one of the main levers for Beijing to build a globally influential International Center for Technology and Innovation and International Exchange Center. Therefore，Beijing continuously improves institutional supply，and enhances the level of digital government construction through promoting the quality and efficiency of government data services capabilities，building a city’s digital intelligent brain，constructing a digital platform for government service，and constructing a service-oriented government with platformization. Although there are problems such as unclear governance concepts，insufficient overall planning and coordination，low public participation，and the prevalence of digital formalism in the process of promoting digital governance，the institutionalized experience of the leadership mechanism and work mode formed in practice，characterized by the combination of “smart governance” and “institutional governance，” has a benchmark leading role for other provinces and cities.
