成都主城区川菜餐饮业距离衰减效应研究

Distance Decay Effect of Sichuan Catering Industry in Main Urban Areas of Chengdu

为探究成都川菜餐饮业距离衰减效应,通过网络平台获取成都市区主营川菜的2 108家餐馆的相关数据。以市中心为起点,绘制公交、骑行以及驾车到达餐馆的实际距离与餐馆数量、网络点评数量、消费水平的关系图进行分析,得出以下结果:(1)餐馆的数量在驾车和骑行约5km处,公交约9km处达到峰值,之后出现距离衰减效应。(2)餐馆的平均点评数量在三种交通距离10km以内呈平稳下降,之后呈波动下降,表现出一定的距离衰减效应;(3)餐馆的人均消费中位数在三种交通距离17km～19km以内,基本在40～50元间波动,之后则出现大幅波动,表明消费水平不存在时空距离衰减效应。

In order to explore the distance decay effect of Sichuan cuisine industry, the relevant data of 2 108 restaurants specializing in Sichuan cuisine in downtown Chengdu were obtained through the network platform. Taking the Tianfu square as a starting point, the paper draws a diagram representing the relationship between the actual distance to the restaurants by bus, by bike and by car, and the number of restaurants, the number of online comments and the level of consumption. The analytical results show that:(1) the number of restaurants reaches a peak at about 5km from downtown by car and by bike and 9km from downtown by public transportation, and then the distance decay effect appears;(2) the average number of comments declines steadily for restaurants within 10km from the downtown by three transportation, and then declines in a fluctuated manner, showing a certain distance decay effect;(3) the median of per capita consumption fluctuates between 40 to 50 Yuan in restaurants within 17 to 19km from downtown by three transportation means, and then there is a large fluctuation, which indicates that the consumption level does not have the distance decay effect.
