Taking 101 policies introduced in China from 2018 to 2024 as a sample, a quantitative evaluation index system has been constructed for new energy vehicle battery recycling policies through text mining, thus establishing a PMC index model based on it. Based on the principles of completeness and timeliness, 12 typical policies are selected for quantitative evaluation with a PMC surface chart drawn from it. Research shows that the overall design of new energy vehicle battery recycling policies is relatively scientific and reasonable, with 12 policies performing well overall. There is a good performance of various policies in policy evaluation and functional aspects, while with such flaws as neglect of the diagnostic and regulatory roles of policies, narrow policy audience, incomplete support measures, and limited coverage of fields. To address these issues, corresponding improvement measures are proposed to enhance policy effectiveness.
