以天津市为例,通过大量问卷调查,总结出城市居民购物出行的空间圈层结构,为国际间相关问题的横向对比奠定了基础。在中地论的基础上,创建了系统描述和详细分析购物出行空间等级结构的新模式,为今后的相关研究提供一种制度和方法。在市场细分的基础上,总结出天津市三种不同收入阶层的购物出行空间等级结构类型,并对其进行了尝试性解释。

To initiate the study on consumers'behaviors in China, the authors, based upon quantities of questionnaires and field surveysin Tianjin, analyze the urban residents' shopping trip space. An aggregated ring shape of shopping trip space of Tianjin's residents, which also reflects the hierarchy of urban region, shows a decay in shopping space (distance) from the higher level merchandises to the lower ones, and prove that the 400 to 500 meters'radius of the trip space for convenient merchandises is applicable and boasts its common meanings throughout the world. More creatively, to describe and analyze the hierarchy of shopping trip space in detail and mathematically, a new mode, which is based upon Central Place Theory, is introduced, upon which some new details are found and analyzed. For the market segment, the authors cluster the residential cases into four groups by income levels, and bring out three kinds of hierarchical distribution of shopping trip space, which differentiates the income groups in shopping trip distance and the preference to the hierarchical central places and with some possible accounts for the structures followed.
