| 摘 要： | 互联网信息传输的特殊性,使网站信息流的距离衰减特征比传统的距离衰减概念更具复杂性。研究以重力模型为基础,建立网站信息流距离衰减模型,以25个旅游网站为例,对旅游网站信息源吸引系数进行评价,并据此划分了网站的信息流距离衰减类型,从而为今后网站信息流"模糊距离衰减"研究奠定了理论与实证基础。研究表明:1)根据旅游网站的吸引强度系数值的大小,可将旅游网站的信息流距离衰减形态划分为4类,即α<800的距离衰减显著型、800<α<1600距离衰减较显著型、1 600<α<2 400不衰减型和α>2 400逆衰减型。2)在不同的吸引系数区段内,旅游网站表现为经济发达地区、旅游资源丰富或特色鲜明地区集中性。 |

| Abstract: | For websites information flows,the distance attenuation characteristics are more difficult to understand and to define because,unlike traditional communications information flows,they are virtual and more complex.Based on the gravity model,this paper built a distance attenuation model of the website information flows,and applied this model to a case study of 25 tourism websites wtih evaluation of the attraction coefficient and distance attenuation types.It was found that 1) there were four types of website information flows in the distance decay,the significant distance attenuation type(α<800),the normal distance attenuation type(800<α<1600),the not attenuation type(1600<α<2400) and the inverse attenuation type(α>2400);and 2) the tourism websites information flows were concentrated in the relative developed areas or the areas with rich tourism resources. |
