Current status of smart city researches in China using the co-word analysis method

As challenges of urban development are progressively prominent, smart city provides a new solution and brings important opportunities. In order to grasp main research hotspots and explore evolution process of the smart city in China, data sources of this paper are journal articles about smart city from China National Knowledge Infrastructure database. Three co-word matrixes are built by BibExcel, and also used to make multivariate statistical analyses by SPSS 22.0. Based on the above analyses, three proposals are put forward: implementation of smart city needs multilateral cooperation under government orientation; smart city construction should integrate developing visions, present diversities with urban characteristics; the development of smart city needs to pay full attention to technological progress and economic growth.
