基于互联网信息的城市商业游憩网点空间竞争域划分研究

Research on Partition of Spacial Competition Domain for Urban Commercial Recreation Networks Based on Internet Information

提出了一种基于互联网信息的空间竞争域划分方法。在Voronoi图的模型中尝试以网络平台数据作加权因子,使空间竞争域体现互联网中的消费者偏好差异,通过对加权Voronoi图的类型划分和地理学解释,描述竞争环境的空间特征。以北京市健身俱乐部为例,选择大众点评网、爱帮等网络平台信息作为权重因子,构建样本网点的传统Voronoi、互联网信息加权Voronoi计算模型并对比边界线、面积等空间特征分析的结果表明:互联网信息对城市商业游憩网点的空间竞争力产生着不同的影响强度,对Voronoi图空间特征的分类和地理解释可以指示商业网点跨越距离阻碍的消费吸引力及竞争差异,弥补传统加权方法未考虑消费者偏好和购物习惯而对竞争域划分表达不足的缺点。

A partition method of spacial competition domain based on the Internet information is presented in this paper.Data on network platform are tried to be made as weight factors in Voronoi diagram model,and the spacial competition domain reflecting consumer preference difference is made in the Internet.The spatial characteristics of competitive environment can be described by partition of weighted Voronoi diagram types and explanation in geography.Fitness clubs in Beijing are taken as example,and information from Public Comment on Nets,Love to Help and other network platform are selected as weight factors.By constructing the traditional Voronoi diagram and calculation model of Internet information weighted Voronoi diagram of sample networks,and comparing the spatial characteristics such as boundary and area,the result of analysis shows that： the spatial competitiveness of urban commercial recreation networks are impacted by Internet information to different degrees;the partition of spatial characteristics and explanation in geography of Voronoi diagram can instruct the consumption attraction overcoming distance block and competitive difference of commercial network,thus can make up for traditional weighted method which did not consider consumer preferences and shopping habits that is result in not enough to express the partition of competition domain.
