Objective: To analyze the evolution path of Chinese medicinal materials industrial policy and summarize the evolution logic，so as to provide references for national policy making and sustainable development of the industry. Methods: The relevant policy documents of the Chinese medicinal materials industry at the national level from 1978 to 2022 were systematically sorted out. Based on ROST CM and Netdraw System Software，the high-frequency words of the policy text were extracted and the policy co-word network of each stage was constructed to analyze the policy text. Results: Industrial policies of Chinese medicinal materials have been put into practice the evolution path of "recovery and exploration，institutionalized development，deepening reform-innovation and optimization". Policy planning and national strategy were increasingly integrated，the diversification mode of policy subjects was gradually stable，the flexibility of policy means was enhanced，and the policy contents were always consistent with the evolution of the industrial structure. Conclusion: Based on the continuous policy evolution，the construction of high-quality medicinal materials can be taken as the breakthrough point in the future，so as to deepen the coordination between industry and national strategy，improve the system of regulations and standards，and further promote the rapid development of Chinese medicinal materials industry.
