ITU‐T's Technical Reports and Specifications 851 Annex D China Institute of Communications (CIC): Index system of smart city Source: http://www.china‐cic.org.cn/english/index.htm The evaluation index system of a smart city includes four major indexes: the information infrastructure, smart applications, support system, and value implementation. These four major indexes form the evaluation system of a smart city with the guidance of other elements, such as the network infrastructure, the construction of public support service system, and smart application, reflecting the level of value implementation of a smart city. The evaluation index system of a smart city can be divided into four dimensions, including 19 second‐level indexes and 57 third‐level indexes [1]. This index system comprehensively considers various aspects, such as the infrastructure development level of urban information network, comprehensive competitiveness, policies and regulations, green and low‐carbon, and culture and technology. It also includes software conditions, such as the intelligent transport administration, the medical education system, the capability of environmental protection network and industrial sustainable development, and the cultural and scientific quality of citizens. This system can embody and index the abstract smart city, forming a distinct guidance, ensuring a more efficient urban administration, a more liveable urban environment, and a continuously increasing happiness index of residents.
