A STUDY OF THE INFORMATION SOURCES,PROCESSING AND DIFFUSION--A CASE STUDY OF GUANGZHOU DAILY

Since the reform of economic system and opening to the outside world, the information service sector in Guangzhou City has developed rapidly. It is necessary to do wide and deep researches on itS developerment and tendency so as to provide a theoretical base for further study.During the period since the reform, the great changes and rising trend in the channels of information sources, relative significance of these channels, technologiCal efficiency of information collection and processing, quality of information products, and sCale, ways and process of information diffusion of Guangzhou Daily, could be identified. Furthermore, the spatial pattern of the information product diffusion of Guangzhou Daily has been characterized by the acceleration of diffUsion speed, expantion of spatial scope, relative centralizaton and absolute decentralization of distribution pattern, with the improvements of regional traffic conditions,residents'incomes and eduCational level, and informational product quality. The theoretical significance of this case study is that a comprehensive and concrete analysis, which focuses on the processes of information collection, processing and diffusion implemented by a typical enterprise for information dissemination in a central city, will be helpful to the understanding of temporal and spatial processes of information in the central city, remedy the defectS of some researches at the macro level, and provide a bee for further study.
