Abstract: With the rapid development of Internet communication technology, humans have undoubtedly entered the era of big data. This era has also put forward new requirements for the construction of digital government, that is, from government information disclosure to government data openness. In order to meet the new requirements, China has implemented a series of policies and measures for the open utilization of government data through the overall integration of government information work. Whether in the process of legal system construction, organizational structure establishment, or platform construction, significant achievements have been made in the open utilization of government data. However, there are still challenges such as low legislative level and neglect of application due to much management, difficulty in grasping data ownership and opening scope, difficulty in implementing data opening procedures, insufficient motivation and ability for data opening, inadequate supervision and management of data open utilization, and less influence of data applications. In order to further institutionalize and standardize the management of government data open utilization, it is necessary to establish an efficient and collaborative organizational operation system, establish a legal norm system for government data open utilization, establish a specialized talent guarantee system, establish a sound supervision and evaluation work system, and create and optimize the environment for government data development and utilization, to promote the legal development of government data open utilization in depth.

Key words:  big data era, government data, open utilization, dilemmas, legal guarantee
