Abstract


Website information flow as the research object, visits to websites provinces as the starting point, \location entropy, Lorenz Curve and Gini Coefficient of a different type of website information flow distance decay concentration and different levels of regional tourism website information flow distance decay of concentration. The study found that: (1) all kinds of website information flow distance decay concentration and economic concentration and the degree of concentration has significant local differences. (2) different levels of regional tourism website information flow distance decay concentration differences. This fully proves that the geographic space and not dead, website information flow is still inseparable from the geography substances, provided the basis for the balanced development of the information society in cyberspace. (3) the same level of travel site information flow distance decay concentration differences. This difference illustrates the complexity of the travel site information flow distance decay. (4) Website information flow the distance attenuation degree of concentration on the construction site and related policies has a practical significance. This paper consists of five parts: the first part is the introduction. This paper first introduces the research background; then a review of the relevant literature analysis, major review of website information flow, information flow distance decay and the three aspects of the research areas of concentration, after the introduction of the research method and research significance; finally established contents and framework of this study. The second part is the research component of website information flow distance decay theory of concentration, the basis for the study of site visitors, given the basic concepts of website information flow distance decay concentration the connotation and determination indicators for the information flows distance attenuation depth study 's laid the foundation. The third part is a different type of website information flow distance decay concentration calculation, is one of the main body of the article. According to the the website holders of different, the information flow is divided into communities (personal) information flow, business website information flow and flow of government website information. Location entropy formula estimates the degree of concentration of the website information flow distance attenuation and quantitative description of the distribution of site visitors in the provinces and cities, and reveal all kinds of website information flow distance decay have common characteristics and differences. The fourth part is calculated different levels of regional tourism website information flow distance decay concentration, is also the subject of the article. Regression analysis in this part of the mainland provinces and cities of the country based on a travel site area of ??the stream flow is divided into three levels, using Lorenz curves and Gini coefficient to calculate the distance decay of the different levels of regional tourism website information flow concentration, reflect a website the visitor distribution of the concentration of the overall situation, confirmed the geographic space is not dead, website information flow is still inseparable from the geography substances. The conclusion of the fifth part for study and discussion. To summarize the results of this study and should be improved at.
