Abstract:The research on industry evolution dynamic mechanism has very important practical significance. In this paper, from module perspective, in the module of related theoretical model based on the analysis of the force of impact of industrial scale . then take GPS navigation industry as the concrete object of analysis, combined with social network analysis method , analyze the GPS navigation in different development stages and each stage of industrial scale expansion of the main driving force, and conclude that the evolution of the industrial power in the early stage of mainly for the modular, middle module integration, late for the application field of module extension; this to lead the industry scale, assist has important significance in industrial adjustment and upgrade is complete.
