To explore the characteristics and policy tools of cell and gene therapy industry policies in China's three major urban agglomerations and to comprehensively improve the development of China's cell and gene therapy industry policies.

Based on the content analysis method, a quantitative text analysis of 88 cell and gene therapy industry-related policies issued by the relevant departments of the three major urban agglomerations was conducted from the dimensions of policy tools and policy themes by constructing a policy tool framework.

In terms of the use of policy tools, supply-type>environment-type>demand-type. In terms of policy themes, "industry" and "development" appear most frequently in the word clouds of the policy texts of the three major city clusters, indicating that the three major urban agglomerations have clear objectives and plans to promote the development of the cell and gene therapy industry.

It is recommended that China balance the use of cell and gene therpy industrial policy tools, increase the proportion of demand-type and environment-type policy tools, emphasize the concept of risk supervision, accelerate the application transformation and industrialization of cell and gene therapy, improve the construction and top-level design of cell and gene therapy industry policies, and promote multi-faceted coordinated development.
