Abstract: The opening of public information resources is a global trend in the era of big data. The government's formulation of a perfect and effective policy system for the opening public information resources is the basic guarantee for steadily advancing the opening public information resources in our country. From the three dimensions of the life cycle, policy tools and policy objects of opening public information resources, the analysis framework of opening public information resources policy is established. According to this framework, the content analysis method is employed to make a quantitative analysis of 310 opening public information resources policies. The results show that the opening of public information resources in our country is still in the initial stage, and the opening policy is mainly focused on the preparatory construction and sharing period in the opening life cycle. The policy tools present an unbalanced state of emphasizing supply but neglecting demand. The distribution of policy objects is uneven, and most of the existing policies act on the government. Therefore, the government should pay attention to the overall life cycle when formulating the policy of opening public information resources and attach importance to the supporting policy for the later work such as operation and maintenance, value-added innovation, supervision and evaluation. Besides, the government should pay full attention to the target of the policy while using the policy tools in a balanced way, so as to achieve the full participation of the government, enterprises, public and non-profit organizations.
