Spatial Pattern of Catering Industry in Nanjing Urban Area Based on the Degree of Public Praise from Internet: A Case Study of Dianping.com

运用大众点评网(南京站)餐饮商户的点评数据,在建立口碑评价指标体系的基础上,计算各商户的口碑综合得分和排名,并对城市餐饮业的空间分布格局进行核密度分析和综合评价。研究发现,南京城区餐饮商户大致分为4个等级,呈现"头小底大"的金字塔形状,口碑较差的商户占据绝大多数,中等口碑的商户较为缺乏,餐饮业发展综合水平较低;餐饮业的空间分布主要呈现出以新街口为服务核心,其他多个次级服务中心共生发展的格局;高等级餐饮服务中心仍旧集中在主城区范围内,发展较为孤立,大致表现为服务质量圈层递减或沿交通线路轴向扩展特征;城市商圈业态也会影响传统和休闲类餐饮商户的空间分布趋势。

In other word, the Catering Industry of Nanjing is now on a low level devel- opment. The spatial pattern of the Catering Industry consists of a core （Xinjiekou） and other secondary service centers roughly demonstrates the feature that service quality decreases by circle pattern, and the top-class Ca- tering businesses that develop separately are mainly in the center of urban area. Also, the state of retail trading in the urban commercial district would affect the spatial distribution of traditional and leisure Catering busi- nesses.
