| Abstract: | This research studied the level of regional informatization from the views of informatization infrastructure, information industry and information resources. Furthermore, we measured the utility of information economy of all provinces and cities in the west of China. Finally, we assessed the comprehensive level of informatization of all provinces and cities in the west of China. The Kohonen Nerve Network Method is used in order to classify the west region into 5 types. And then we analyzed the space characters of regional informatization difference. Based on this, we put forward some measures for the informatization development of all provinces and cities in the west of China. |
