Exploring the innovative development mode of digitalization of China’s intangible cultural heritage, the study focuses on applying and improving the traditional entropy value method in the digital evaluation of intangible cultural heritage, and is dedicated to enhancing the dissemination effect and public cognition of intangible cultural heritage. The study first standardizes the data, including the extreme value processing method, z-score standardization method, etc., and then applies the improved entropy value method for comprehensive evaluation. This paper’s improved entropy value method focuses on the Nature of the evaluation indexes, making the index data more genuinely reflect the relationship between the original values. The study results show that the index of understanding non-heritage culture through the Internet channel is 0.6, significantly higher than other channels. The user experience score of non-heritage culture after digitization increased from 2.48 to 4.43, indicating that digitization technology significantly improved the user experience of non-heritage culture. In addition, digitization technology enhanced NRM cultural heritage’s aesthetic, novelty and social communication. Digitization technology effectively enhances the communication effect and public perception of ICH.
