职住建成环境对郊区居民通勤方式的影响——以上海市为例

With the development of suburbanization, the spatial pattern between residential place and workplace has become more separated, and the problem caused by citizen's more motorized travels also become an important issue for urban development. Based on the urban POI (point of interest) data and the survey data of suburban residents' activity logs in a considerable number of suburban communities in Shanghai in 2017, this study established the multiple logit models to analyze the impact of the built environment, both around the residential and working areas for suburban residents on commuting modes, and the multiple logit models also involve residents' social and economic characteristics as control variables. Also, a mediation effect model is established to explore the indirect effects between commuting distance and commuting mode, especially for some residents who need to commute in a long distance. By the analytical outcomes of the multiple logit models and the mediation effect model, it found that some important measures such as improving the accessibility of the subway station in public transportation system for suburban communities, improving the degree of mixed land-use in neighborhood, and controlling the density of facilities both in neighborhood and workplace, are some beneficial and effective way to reduce car-use in commuting mode for residents.
