The development of information technology proves the possibility of acquiring large samples of policy text information and promotes innovative research based on the policy informatics approach of fusing data from multiple sources. This paper constructs a new public policy model based on existing data on economic system reform, and uses multi-types of textual big data such as government website, official weblog, and social media as the object of collection, to conduct a big data measurement on policy concerns related to the theory and practice of economic system reform since the reform and opening up. And this paper constructs a fine-grained measurement and portray the evolutionary trend of policy concerns and policy implementation. Based on the database, this paper helps to analyse the economic development trend since the reform and opening up, evaluate and monitor the implementation effect of different incentive policies and establish an iterative feedback mechanism, and provides a reference for relevant decision-making departments.
