Application And Validity Analysis of IoT In Smart City Based On Entropy Method

This work aims to analyze the application of IoT in the construction of smart city using entropy method, and explore the validity of IoT in smart city based on the input-output perspective. Based on the SC IoT-oriented EIS model, this work can analyze the development status of 31 Chinese smart cities. From 2011–2020, Shanghai(0.1177–0.1607), Beijing(0.1049–0.1132) ,Guangzhou(0.013–0.1378), Chongqing(0.0708–0.1019) are the four cities with the best status of smart city, the development status of smart city in many central and western regions is still relatively low, such as Taiyuan (0.0151–0.0198), Changchun(0.0202–0.0223),Wuhan(0.0638–0.0331), Xining(0.0102–0.0111),Urumqi(0.0147–0.0167). From the input perspective, the input of capital and labor in IoT has obviously positive correlation with the development of smart city, which have significantly promoted the development of smart city. From the output perspective, IoT has not only promoted the economic development of smart city, but also caused a series of environmental pollution problems. In conclusion, the application of the IoT has promoted the development of smart city, China should further strengthen the investment in IoT technology, so that it can solve the problems of unbalanced development and environmental pollution in urban areas of china
