Recently, the Office of the State Council issued the Guiding Opinions on Accelerating the Promotion of "Doing One Thing at a Time" to Build an Upgraded Edition of Government Affairs Services, proposing to promote the wide application of digital technology in government management services, optimize business processes, open up business systems, strengthen data sharing, and promote more cross departmental and cross level government affairs services with strong relevance and large demand to achieve "doing one thing at a time", Further improve the sense of experience and gain of enterprises and the masses. In a modern country, the government needs to provide residents with basic public services and public goods, and ensure their accessibility, quality and fairness. The quality and efficiency of service provision, that is, whether it is done well or quickly, are important criteria for service-oriented governments. Accelerating the promotion of "one thing at a time" will help reduce institutional transaction costs, including both economic costs and time costs, improve service experience and optimize the business environment. "One thing at a time" is not a new word. The Implementation Outline for Building a Government under the Rule of Law (2021-2025), issued in August 2021, proposes to comprehensively improve the level of government services, improve the systems of first question responsibility, one-time notification, one window acceptance, and independent handling, accelerate the promotion of "trans provincial" government services, and basically achieve "trans provincial" high frequency issues by the end of 2021. Vigorously promote "one thing at a time", and provide more package and thematic integration services. The acceleration of "doing one thing at a time" should be supported by digital technology. Only by using digital technology to integrate data resources, get through the state of government departments, departments and levels acting independently, realize data circulation and release data value, can the government improve its operational efficiency and provide better service capabilities. Some experts said that we should build a service-oriented government with digital technology and build a convenient, efficient, clean and fair government image to optimize the business environment and the living environment of the people. Data sharing and business collaboration can also help reduce the repeated entry of filling materials by grassroots staff, reduce the pressure on grassroots governments, and improve work efficiency. In recent years, the CPC Central Committee and the State Council, from the overall perspective of promoting the modernization of the national governance system and governance capacity, have accurately grasped the global trend and characteristics of digital, networked and intelligent development, and made a series of major deployments around the implementation of the strategy of network power and big data strategy. Through the efforts of all parties, remarkable achievements have been made in the construction and application of government business information systems at all levels, positive progress has been made in data sharing, development and utilization, and the efficiency of integrated government services and supervision has been greatly improved. Before the nationwide implementation of "one thing at a time", many regions and departments have started such attempts. Innovative practices such as "running at most once", "one network for all", "one network for unified management", "one network for coordination", and "handling complaints as soon as possible" continue to emerge, and have produced good social benefits. Such an inward cutting reform is in line with the concept of people centred development. The government departments put themselves in the other's shoes, optimized services, refined scenes, designed lists, and provided services from the perspective of the applicants and enterprises, helping the masses to clarify their ideas and processes. Only in this way can the masses hold their breath less, have a smooth mind and get more
