本研究采用了主成分分析法对31个旅游网站的综合竞争力进行定量评价,计算出旅游网站的标准化综合竞争力得分,结合扩散断裂点理论对其信息辐射范围进行界定,应用Arc GIS软件生成辐射范围图,并对旅游网站的辐射范围进行分析。研究表明:1旅游网站信息的辐射范围大小不仅取决于该网站的标准化综合竞争力,还取决于与相邻竞争网站的欧氏距离。2全国旅游网站信息辐射范围分布不均匀,体现了旅游网站布设的不均衡性。我国的中部及东部沿海地区,旅游网站密集,竞争比较激烈,信息辐射范围较小。而西部、东北等其他地区网站之间距离较远,竞争环境比较宽松,信息辐射范围较广。3每个旅游网站的辐射范围的边界可以确定为唯一。从而为旅游网站企业制定新的旅游产品、营销策划、目标市场等提供依据。
In this study, we use the method of principal component analysis to quantitatively evaluate the comprehensive competitiveness of 31 tourism websites, calculate the standardized comprehensive competitiveness score of tourism websites, and define the information radiation scope by using diffusion fracture point theory. ArcGIS software is used to generate Radiation range map, and the radiation of travel sites for analysis. The research shows that: 1 The size of the radiation field of tourism website information depends not only on the standardized comprehensive competitiveness of the website, but also on the Euclidean distance between the websites competing with neighboring sites. 2 National Tourism website information radiation distribution is uneven, reflecting the layout of the tourism website is not balanced. In the central and eastern coastal areas of China, the tourism websites are intensive, the competition is fiercer, and the scope of information radiation is smaller. However, the websites in other regions in the west and northeast China are far apart, the competitive environment is relatively loose, and the information radiation scope is wider. 3 The boundaries of the radiation range of each travel site can be identified as unique. So as to provide a basis for tourism website enterprises to formulate new tourism products, marketing plans and target markets.
