RETRACTED: Analysis on the Development of Smart City of Big Cities in China and Its Effect to Economic Structure Based on Entropy Method (Retracted Article)

This work aims to analyze the construction of smart cities in China's large cities and its impact on the economic structure. Some developed countries, such as the United States and Europe, have established mature smart city evaluation systems. Therefore, this work draws on the evaluation system of smart cities in developed countries to study the development status of smart cities in large cities in China. An extend linear system evaluation model is established. Besides, five first-level indicators and 24 second-level indicators are established from the five aspects: urban infrastructure, technological innovation, smart economy, human services, and intelligent environment to evaluate the development status of the city. In addition, a susceptible infected system model has been established to study the impact of smart city construction on the industrial structure. The research results demonstrate that the development level of smart cities and smart industries in eastern China is relatively high, and the comprehensive scores of smart city construction in Beijing, Shanghai, Guangzhou, Shenzhen, and Chongqing all exceed 0.082. However, the development level of smart cities and smart industries in the central and western regions is relatively low. The comprehensive evaluation scores of smart cities such as Tianjin, Hangzhou, and Wuhan are between 0.35 and 0.8, and technological innovation still needs to be further developed. In conclusion, the development gap between eastern, central, and western China has further widened with time. This work provides possible research experience for China's smart city construction and industrial construction.
