智慧城市的多元主体主要包括政府管理智能化信息主体、道路基础设施智能化信息主体、社会服务智能化信息主体、生产管理智能化信息主体。多主体间的信息协同是智慧城市管理者对智慧城市进行更加有效的管理、智慧城市中的居民得到更加便捷生活的关键。文章以信息生态理论为指导,设计基于多元主体协同的智慧城市信息生态链总体模型,为智慧城市的建设和管理提供参考。 The multiple subjects of a smart city mainly include the main body of intelligent management of government information, the intelligent information body of road infrastructure, the intelligent information body of social service and the intelligent information body of production management. Information collaboration among multiple subjects is the key to smarter city managers to manage smarter cities more effectively and to make life easier for smart city residents. Guided by the theory of information ecology, the article designs the overall model of smart city information ecological chain based on the coordination of multiple subjects, and provides a reference for the construction and management of smart city.
