数字城市的理念演化、主要类别及未来趋势研究

Study on the Evolution,Categories and Trend of the Concept of Digital Cities

城市与技术的关系由来已久,但将“数字”这一技术概念与城市连接成为专有名词却是新事物。本文从技术变迁的外生驱动和城市发展问题的内生需求两个角度探讨数字城市兴起及发展的动因,通过厘定数字城市的相关概念,分析数字城市的理念演化过程,将数字城市分为“作为实体城市信息投射的数字城市”“作为实体城市机能强化的数字城市”和“作为实体城市环境延伸的数字城市”三大类别,并探讨了未来数字城市发展的主要趋势和当前数字城市建设所存在的突出问题。

The relationship between city and technology enjoys a long history,but it is a new thing to connect the technical concept of“digital”with“city”as a proper term.This paper discusses the reasons for the rise and development of digital cities from two perspectives:the exogenous drive of technological change and the endogenous needs of urban development.Starting from the relevant concepts of digital cities,this paper first analyzes the evolution of the concept of digital cities.Then it divides digital cities into three categories:digital cities as information projections of physical cities,as functionally-enhanced physical cities and as extension of physical cities,and analyzed corresponding cases from a global perspective.Finally,the main trends of the development of digital cities in the future and the practical problems in current digital city construction are discussed.
