基于共链分析图形化描述纸业企业竞争地位

假定两个企业网站的共链频次可以视作这两家企业相似性的一个度量。既然相似或相关的企业之间存在竞争，那么共链数据就可以用来描绘企业的竞争地位。选择36家纸业公司，从雅虎和雅虎中国上搜集到这些公司的共链数据，利用多维尺度分析法描绘出这些公司在纸业各个产品组中聚类关系图，绘制出社会网络图，用凝聚子群分析中的K-核分析出其隐含的子结构。从雅虎和雅虎中国上搜集的共链数据，可反映出全球市场和中国市场的情形，以上结论可以揭示出企业在这两个市场中的竞争地位。

Mapping Paper Industry Business Competitive Positions Using Web Co-link Analysis

We hypothesized that the number of co-links to a pair of business Websites is a measure of the similarity between the two companies. Since similar or related businesses are competing businesses, the co-link data can be used to map business competitive positions. We selected 36 papermaking companies for the study and collected co-link data to these companies from Yahoo!(http://www.yahoo.com/ and http://cn.yahoo.com/). Multidimensional scaling (MDS) analysis and Social Network Analysis(SNA) on the co-link data correctly mapped these companies into papermaking industry sectors，and the k-core analysis are used to find the sub-structure of the map. We collected data in a way that would reflect two markets, the global market and the Chinese market. Results from the two data sets revealed the competitive positions of the companies in the two markets.
