ObjectiveTo analyze the policy environment of clinical research in China, providing valuable insights for the formulation and enhancement of policies. MethodsAt the national level in our country, policies related to clinical research were selected as the research subject. The method of text mining was employed to extract high-frequency words from policy texts. By constructing the policy modeling consistency (PMC) index model, evaluations of the relevant policies regarding clinical research in our country were quantified from multiple dimensions including internal consistency, effectiveness, and scope of influence. ResultsThe average PMC index of 22 clinical research policies in our country was 6.87. Among them, 10 policies demonstrated an excellent performance, while 12 policies were considered qualified. This suggested that the overall quality of clinical research policies at the national level was good, yet there was still considerable room for improvement. ConclusionPolicies regarding clinical research have entered a high-speed development stage and exhibit basic completeness in China. However, these policies appear somewhat independent of each other and inadequate rule of law.
