China is in a process of urbanization and is aiming at a type of people-centered urbanization. The main purpose of developing a “smart city”is to help this type urbanization and to serve the people of the city. From 2012 to 2015, China has chosen more than 300 cities or towns to be national pilot“smart cities.”These pilot smart cities are located in more than 30 provinces around China, which differ greatly in thousands ways. So we advocated“One City One Policy”. In 2012, MOHURD announced 90 cities as first batch of pilot smart cities. After three years, some pilot cities achieved great progress. This paper introduces five example cities (including town, district) as five different models of China’s smart city development. They are: Guilin city; Yunlong demonstration zone; Panyu District; Yangling Agricultural Hi-tech Industries Demonstration Zone; Lecong town. This paper also introduces our standardization work on smart city field at present.
