Guidelines for the implementation of the China Manufacturing Regional Action Plan focus on the development of major areas and sub-areas in various provinces and cities. In order to comprehensively understand provincial and municipal action plans in China, consistency analyses for major development areas and difference analyses for major development sub-areas are fundamental. This paper proposes a method of analyzing policy documents based on Chinese word segmentation, feature extraction, and similarity calculation using text mining, which can help to analyze a large number of policy documents efficiently. The results indicate consistencies and differences in the action guidelines for various provinces and cities.
