METHODS ：The policies and documents issued by 169 national high-tech industrial development zone （hereinafter reffered to as “National high-tech zone ”） official websites from Jan. 2010 to Dec. 2019 were collected to screen policies specifically for the biomedical industry and the development policy of biomedical industry mentioned in all industrial policies. Excel 2019 software was used to summarize and analyze policy information. Gensim package was used to preprocess the policy texts and construct LDA topic model to extract the potential semantic information from the policy texts. RESULTS ：A total of 518 policy texts were collected ，including 58 617 effective words ；high-frequency words included project ，talent，support，subsidy，innovation，etc.；8 themes were extracted ， ranked by theme intensity as technological innovation ，talent construction ，financing support ，project financial support ，tax incentives，resource guidance ，export trade ，and construction of small and medium-sized enterprises ，with the intensities of 0.299， 0.168，0.134，0.116，0.113，0.063，0.058 and 0.049，respectively. CONCLUSIONS ：The biomedical industry policy of the national high-tech zone is mainly based on technological innovation ，talent construction and financing support ，and lacks attention to the construction of small and medium-sized enterprises ，resource guidance ，and export trade. In the future ，the national high-tech zone ’s policy support and system construction for the biomedical industry should focus on improving policy incentives and balancing the proportion of policy applications in various fields ；encourage enterprises to expand overseas markets ，learn overseas advanced technologies ，and strengthen multilateral cooperation in scientific research and other fields ；support the corresponding policies to enhance exchanges and cooperation between enterprises ，give play to the leading role of leading enterprises and famous brand products ，and promote the development of small and medium-sized enterprises.
