Organization of information platform for manufacturing clusters is researched based on the characteristics of information. The characteristics of multiple sources and heterogeneity are analyzed. The information characteristics are described by four attributes-particle size, transmission frequency, effectiveness, and update frequency. Information collection and information users are geographic dispersion. The forms are diversified. The management is relatively concentrated. According to the characteristics of information, the distributed database organization is used. Function modules are organized by Cooperative mechanisms. Information organization flow chart is put forward. Multi-sources information processing is researched, which is the key technology of information organization. The study provides method guide for organization of information platform for manufacturing clusters.
