Under the background of “construction of digital government in thenew era”, government data sharing is the core of promoting the construction ofdigital government. The development of data sharing can not only acceleratethe construction of digital government, improve the national governancecapacity, but also improve the efficiency of government to serve the people,solve the practical needs of the people, and facilitate people’s lives. However, since government data involves many aspects, including but not limited tonational interests, public security, trade secrets, personal privacy and otherhighly sensitive information, it is easy to appear in the collection, transmission,storage, sharing and application, a series of data security risks. Therefore, it isnecessary to strengthen the security supervision of government data, regulatethe supervision path, and ensure the orderly sharing of government data on theroad of rule of law. However, because China has not yet formed the relevantlegislation of government data sharing, the scope and method of data sharing arenot uniform, resulting in an increase in the difficulty coefficient of supervision.The government data security supervision mechanism is not perfect, resultingin the absence of a clear data security management department for supervisionand accountability in the event of data leakage. In addition, governmentdata sharing projects rely on project mandates, and the involvement of thirdparties increases the risk of data security leaks. Therefore, we must clarify thecurrent situation of government data security supervision, pay attention to thedifficulties faced by data security supervision at this stage, implement relevantlegislation on government data sharing, establish a unified government dataclassification and classification system, clarify the functional departments ofgovernment data security supervision, improve the government's accountabilitymethod and accountability procedure in data supervision, and explore a newpath of more legalized data supervision. In order to realize the efficient sharingof government data across regions and departments.
