Abstract: Research on evidence-based policies is currently at the forefront of public management methods and theories. In order to present the cutting-edge issues in the research field, Systematic Literature Review was used to summarize the results of evidence-based policy research. The main content of evidence-based policy research is the theoretical research of evidence-based policy, the application mechanism of technology in evidence-based policy, the problem of government decision-making based on evidence-based theory, and the application of evidence-based practice in other social sciences. Among them, the general idea behind the formation of evidence-based policies, namely the process of "data information evidence practice", is not only a one-way operation, but also contains ways of feedback, transformation, and promotion. In this regard, this paper puts forward the research topic framework of evidence-based policy, and probes into four research contents centering on two major issues. This paper further puts forward future prospects from four perspectives: government evidence-based governance, integrating into local culture, technology enablement and evidence grading and quantification. This paper has important theoretical value and can help the academic circle grasp the theoretical status of evidence-based policy.
