Abstract:As an emerging industry with great development potential, cultural industry is moving towards the pillar industry of national economy, and the national cultural industry policy is the driving force and guarantee for the development of cultural industry, and it is of great practical significance to analyze, study and quantitatively evaluate. The word frequency of national cultural industry policies from "11th Five-Year Plan" to "14th Five-Year Plan" through text mining method was analyzed, the evaluation system of cultural industry policies according to the results was established, and the PMC index model to analyze and evaluate the national cultural industry policies from "11th Five-Year Plan" to "14th Five-Year Plan" was constructed. The PMC index model was constructed to quantitatively evaluate 12 national cultural industry policies from the 11th Five-Year Plan to the 14th Five-Year Plan. The result shows that the 12 selected national cultural industry policies are generally well-designed, with certain scientificity and feasibility, but there are low ratings in terms of policy perspective, incentives and policy timeliness, which still need to be improved.
