Smart City Development Index

Abstract

Smart city is a new stage of development after industrial city, and a product of human science and society. Task 1: Based on the development of smart city, it selects 26 indicators of 7 main factors and draws the hierarchical structure chart by holding the scientific selection principle. When determining the weight of factors at each layer, it uses the consistent matrix method to compare the pair and pair factors, judges the consistency ratio of the obtained matrix, and finally determines the weight of each indicator. The smart city development index is the value of the second-level index multiplied by their respective weights and then summed, and the development level of the city is divided with 0.5 as the standard. Task 2: Firstly, compared with China’s GDP, it is found that Hangzhou’s growth rate is always higher than that of China, while Harbin’s GDP is lower than Hangzhou’s and its development is slower. According to the development index proposed in the first question, the scores of Hangzhou and Harbin are calculated and the trend chart is drawn. It is found that before 2017, the development of Harbin was higher than that of Hangzhou, but after that, the growth rate of Hangzhou was faster and Hangzhou surpassed Harbin. After 2017, the scores of Hangzhou both exceeded 50, that is, both were above the average development level. Task 4: Based on the system dynamics theory, the smart city system dynamic model is constructed based on the data of Hangzhou City. The model includes seven parts: smart economy, intelligent humanity, intelligent energy management, intelligent medical treatment, intelligent urban infrastructure, intelligent environmental protection, and urban planning and crowd management. Vensim was used to simulate the model, and the results showed that the future construction level of Hangzhou would be stable but rising, and all subsystems would play an important role in urban development, among which the smart economy was the most obvious. Finally, according to the conclusions of the research, some suggestions and plans are provided for Hangzhou and Harbin from the aspects of green development, science and technology, government leadership and so on.
