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.展开更多

Mianzhu is an example that is officially named as one of the pilot cities for multi-plan integration on the county level. The paper firstly analyzes the problems associated with multi-plan integration in Mianzhu, including the indeterminate hierarchy of the planning system, the disunity of technical standards, problems regarding spatial order, coordination and division of powers and functions, and the intensive utilization of spatial resources, the lack of a coordination mechanism, and low participation of experts and the public. Secondly, by learning from Germany's spatial planning, and also practical experiences of pilot cities for multi-plan integration in China, this paper creatively brings in the connotation of multi-plan integration on the county level, and further proposes a power division based on three-level planning system and three kinds of space, the reinforcement of a spatial order, intensive spatial utilization, and a planning coordination mechanism, hoping to provide reference to other cities.展开更多
