The system selects eight key indicators from four dimensions: digital infrastructure, industry scale, innovation environment, and integration level. These indicators include the number of broadband internet access ports, the number of mobile phone base stations, total telecommunications business volume, software product revenue, R&D expenditure, number of authorized patents, the digital inclusive finance index, and e-commerce sales. Using a weighting calculation method that combines global principal component analysis with the global entropy method, the digital economy level of 30 provinces in China over eight years is measured, resulting in a comprehensive index and ranking of the digital economy development level in various regions. The regional differences are analyzed, and reasonable suggestions are provided. The results reveal that the development of the digital economy is uneven across regions, generally showing a decreasing trend from the eastern to the northwestern regions.展开更多
