Evaluation of Urban Digital Transformation Level and Improvement Path Based on Entropy Value and Analytic Hierarchy Process: A Case Study of the Yangtze River Economic Belt

—Digital transformation is an inevitable path for cities with the rapid development of emerging technologies, and it is important to promote the efficient development of urban agglomerations. Taking the Yangtze River Economic Belt as an example, this paper establishes an evaluation model of urban digital transformation level based on entropy value-hierarchy analysis by constructing an index system of digital transformation level, and conducts a comparison of the differences in digital transformation level in the Yangtze River Economic Belt in time and space. It analyzes the differences in the contribution of each index and the gap in the digital transformation level of various provinces and cities in the Yangtze River Economic Belt, and explores the path to improve the digital transformation level of the Yangtze River Economic Belt. The results show that the overall digital transformation of the Yangtze River Economic Belt needs the support of economy, ecology, life, industry and other aspects, while the digital transformation of provinces and cities mainly depends on the digitization of economy and industry
