The linkage analysis of innovation systems about development of the 3G international technology standards

The International Telecommunication Union (ITU) has identified the 4 technology standards as international technology standards respectively with development of R&D (Research and Development) in the telecommunication industry. With the cases of CDMA (Code-Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) and WiMAX (Worldwide Interoperability for Microwave Access), this paper thinks that there are the innovation systems in development of the 3G (3 generation) international standards, in which interaction between the R&D and the service activities is a way inspiring innovation. For this, the paper set up a framework-Linkage among factors in the innovation systems. Here, the term linkage refers to the sustainable interaction among the actors in the system, and the linkage method makes just conceptual link between factors of the innovation systems and is a qualitative analysis way.
