Analysis And Practice Of City Informationization Assessment Method Based On GIS

Global Information is an important reflection of the economic development in society progress. The information-based new economy is advancing vibrantly. Thus, it is of great point to measure the information-industry's scale and information's level, which is not only a highly theoretical issue, but also a subject of great practical significance. On the basis of existing information index system, the evaluation index system suitable to the Chinese current information situation is designed. Besides, GIS, as a tool, is introduced to visualize and analyze the level of information from the spatial and time scale, and a spatial correlation model of information level is built. The main achievements and innovations are summarized as follows:(1) A set of representative information evaluation index models of the world are reviewed and compared. Referring the existing models, especially the one published by the china Ministry of Information Industry, a new regional information evaluation index model is designed.(2) The information index data for research comes from the year of 2000, 2005 and 2007, and it can be separated into two parts, province-level and city-level. After data analysis, two principle factors names as"application index"and"potential index"are extracted, through which the model of regional information elevation is built and then the weights of the original index data to the model are found different between province-level and city-level.(3) Taking the information level of Jiangsu Province as example, with the assistance of GIS tools, the spatial distribution and development trends are visualized and analyzed. The result shows that, the information level (especially the apply level) of a city has some relation to its neighbors, and is in a trend of advancing.(4) Considering the spatial distribution imbalance of information level in China, it is essential to evaluate the relationship between information level and geography factors. With the analysis tool of GIS, the spatial relationship model is built, and the model declares that, the information level has little relationship with Topography, which can only affects human in originally period, but high with the position of airport, which represents a high transport pattern.
