Returning migrant workers to their hometowns to start businesses is of great significance to promoting rural revitalization and realizing common prosperity. Based on the text features and high-frequency words of the text, the pmc index model was used to construct an evaluation index system of the policy of returning migrant workers to start a business, including 10 first-level indicators and 38 second-level indicators. The quantitative evaluation of the policy of returning migrant workers to start a business was carried out, and the pmc curve was drawn. The study found that the overall score of the sample of migrant workers returning home to start a business is excellent, the design is relatively scientific and reasonable, of which 2 are perfect policies, 7 are excellent policies, and 1 is acceptable policies, but the policy timeliness and incentive measures need to be improved.
