A STUDY ON SHOPPING BEHAVIOR OF BEIJING RESIDENTS:THE SPATIAL DIFFERENTIATION OF INFLUENCING FACTORS
基于北京问卷调查数据，用回归模型分析不同区位（城区、郊区、远郊）影响居民购物出行距离的关键因素差异，发现商业密度、年龄、购物频率和交通方式的作用随空间变化。
In China,it has been conducted a lot of empirical researches on shopping behavior of residents,but until now it has rarely studied the spatial differentiation of shopping influencing factors in a single city.Based on questionnaire survey and field investigation in Beijing,this paper considers the travel distance from home to the most frequently shopping sites as dependent variable while considers a series of factors about personal social-economic attributes,family attributes,spatial attributes and shopping activities as independent variables.We formulate many OLS regression models and WLS regression models.The results indicate: firstly,certain factors affect the shopping distance of residents in various locations distinctively.Secondly,the major influencing factors are different,for example,the major factors are commercial density and age in inner city,but shopping frequency and age in suburbs.Thirdly,although the mode of transportation is significant in various locations,in the inner city and suburb the most influencing transportation is foot and public transportation,in the exurb,however,it is private car.
