Recently, the Central Committee of the Communist Party of China and the State Council issued the "Party and State Institutional Reform Plan", proposing the establishment of a national data bureau. Unlike the previous "optional action" of setting up big data bureaus in some provinces and cities, the new round of institutional reform requires "the establishment of provincial government data management institutions in combination with actual conditions", which is significant for improving the digital government and data governance system. Strengthening the construction of digital government is a fundamental project in the construction of digital China. Clarifying the responsibility system is the leading condition for the construction of digital government and digital governance. Clarifying the rights and responsibilities of government departments is a common feature of digital governance experience across regions. For example, in Shanghai, various departments in the digital governance system have clearly defined their responsibilities, forming a "one network unified management" item catalog, responsibility list, and process standards. In Pingshan District of Shenzhen City, the District Committee's Editorial Office and the Administration of Government Service Data Management Bureau have coordinated and promoted the clarification and legalization of responsibilities through benchmarking laws, regulations, and departmental consultations, forming a "one network unified management" responsibility list covering 1659 levels and end level classifications. For example, noise management is divided into 30 specific matters such as industrial noise, commercial noise, and construction site noise. These matters have clearly defined the competent department and implementation level. The department "quarrels" are in the "front", and the smooth governance is in the "back". On the contrary, if the responsibility system is not clear and you are in a hurry to install equipment, build systems, and operate, you will suffer a lot. For example, the digital governance system collects a large amount of problem information, but the "who will handle it and how to handle it" is unclear. The relevant departments "pass the buck and argue", resulting in "system idling and governance suspension". In the end, it can only add a set of systems, increasing government operating costs; Another example is that in a region where different levels are engaged in the construction of big data systems, if there is a lack of necessary overall coordination, it is easy to see a situation where the upper and lower levels of government are "at different paces," leading to a new "digital divide.". "If it is directly controlled by superiors, it may lead to the need for some regions that have been functioning well to" cut their feet to fit their shoes "in order to comply with superiors, wasting resources accumulated in the past and failing to meet the needs of the region.". Not long ago, the "Overall Layout Plan for the Construction of Digital China" issued by the Central Committee of the Communist Party of China and the State Council pointed out that "building a national data management system and mechanism, and improving data overall management institutions at all levels" is a basic condition for the construction of digital China. Clarifying the responsibilities and relationships of various departments, units, and levels is an inherent and necessary requirement in promoting digital governance. Firstly, clarify the responsibilities of digital platform construction. The construction of digital platforms not only covers the construction and integration of "hardware" such as government cloud platforms, government networks, and spatial geographic information systems, but also involves the integration of "software" such as data information from various departments and business units. In this process, it is necessary to clarify the rights and responsibilities of each department and unit in terms of data collection, system access, information interaction, and other aspects, so as to form a systematic, scientific, open, inclusive, and safe responsibility system. Secondly, clarify the responsibilities of digital platform applications. The construction of a digital platform serves the solution of specific issues. Only by clarifying the closed-loop responsibility system for digital governance in advance can we ensure that data collection is "complete" and risk early warning is done early
