本文探讨了传统信息系统在电子商务环境下的缺陷,在技术、管理、组织和个人用户四个层面上论述了适应EC环境的信息系统的特征;在研究ECIS组成元素的基础上,从集成的数据环境、系统结构和功能结构三个方面,以信息资源管理的视角,提出一种面向电子商务活动的信息系统设计模式。该设计模式认为ECIS的设计是EC供应链的上下游企业、客户以及第三方机构协同建设的过程,而ECIS的功能结构应该从信息资源管理和配置的角度进行划分。 This paper discusses the defects of traditional information system in e-commerce environment, and discusses the characteristics of information system adapting to EC environment at four levels of technology, management, organization and individual user. On the basis of studying the components of ECIS, Data environment, system structure and function structure, this paper proposes a design mode of information system for e-commerce activities from the perspective of information resource management. The design pattern considers the design of ECIS as the collaborative process of upstream and downstream enterprises, customers and third-party agencies in EC supply chain. The functional structure of ECIS should be divided from the perspective of information resource management and configuration.
