城市职购出行距离的影响因素与优化对策研究——以武汉市为例

Research on Influencing Factorsand Optimization Strategies of Travel Distance forWorkplace-originated Shopping Trips: Taking Wuhan City as an Example

职购行为是城市居民重要的消费活动,对其特征及成因的理解有助于完善城市就业中心与商业中心的协调布局,丰富城市生活空间的理论认识。以武汉市为例,运用LBS位置服务数据、抽样调查数据、GIS空间分析与结构方程模型方法,测度职购出行距离,揭示其影响因素。结果表明:武汉城市居民职购活动以中短程出行为主,职购距离的圈层异质性明显,城市边缘及外围地区职购便利性更差。就业地商业可达性、社会经济属性、就业通勤成本、网络购物习惯等是影响职购出行距离的重要因素。应优先对10余处职购不便问题突出的就业集聚区开展优化,既要推动基于多因素协同的综合优化,也要区别不同就业集聚区职购困难的诱致主因,实施分类型、差异化的改进措施。

Workplace-originated shopping trip is an important content of residents’consumption activities.Understanding its characteristics and causes can help improve the coordinated layout of urban employment centers and commercial centers,and enrich the theoretical understanding of urban living space.Taking Wuhan as an example,the study uses location-based service data,sample survey data,GIS spatial analysis and structural equation modeling to measure the travel distance of workplace-originated shopping trips,and reveal its influencing factors.The study found that Wuhan residents’workplace-originated shopping activities are dominated by short and medium-range trips,the heterogeneity of travel distances is obvious,and convenience is worse in the urban fringe areas.The commercial accessibility of employment centers,individuals’socio-economic attributes,commuting costs,and online shopping habits are important factors.The study suggests that optimization should be carried out in more than 10 employment centers with prominent inconveniences,not only to promote comprehensive optimization based on multifactorial synergy,but also to differentiate the main causes of workplace-originated shopping difficulties,and to implement type-specific improvement measures.
