摘要/Abstract

摘要： 现有共享单车建成环境研究多以出行量作为表征指标，难以反映不同区域对骑行活动的吸引能力和空间组织特征。本文基于深圳市共享单车订单数据构建共享单车出行势能场，从密度、多样性、设计、目的地可达性和公共交通临近度这5个维度表征建成环境特征，采用多尺度地理加权回归模型分析建成环境对共享单车出行势能的时空异质性影响。结果表明：相较于以出行需求为因变量的模型，以出行势能为因变量时，慢行道路密度、到商圈中心的距离和地铁可达性的作用尺度均由全局或中高尺度收缩至局部尺度，表明共享单车出行吸引力的形成过程具有更明显的局部空间依赖特征。到商圈中心的距离对出行势能整体呈负向作用，商业设施集聚强化了共享单车向城市核心区域集聚的空间格局；人口密度对出行势能呈稳定正向作用，且晚高峰影响更强；地铁可达性对出行势能的影响呈片区化、节点化分异；慢行道路密度对共享单车出行吸引力的促进作用具有局部差异。

Abstract: Existing studies on the impact of built environment on bike-sharing commonly use the trip volume as the main indicator of travel demand, which may fail to capture the area-level attractiveness for bike-sharing trips and its spatial organization. Based on the bike-sharing order data from Shenzhen, this study constructs a bike-sharing mobility potential field and characterizes the built environment attributes from five dimensions: density, diversity, design, destination accessibility, and public transit proximity. A multiscale geographically weighted regression model is employed to analyze the spatiotemporal heterogeneity of the impacts of built environment on bike-sharing mobility potential. The results show that, compared with the model using the trip demand as the dependent variable, the mobility potential reveals more localized built environment effects. The bandwidths of non-motorized road density, distance to the business district center, and metro accessibility decrease from global or medium-to-large scales to local scales, which indicate that the formation of bike-sharing attractiveness exhibits stronger local spatial dependence. The distance to the business district center has an overall negative effect on the mobility potential, suggesting that commercial agglomeration strengthens the tendency of bike-sharing trips to cluster toward urban core areas. Population density has a stable positive effect on the mobility potential, with a stronger influence during the evening peak. The effect of metro accessibility on the mobility potential exhibits the spatial differentiation characterized by zonal clustering and node-oriented patterns, while the positive effect of non motorized road density on the bike-sharing attractiveness varies across local contexts.

Key words: urban transportation, spatiotemporal heterogeneity, multiscale geographically weighted regression, bike-sharing mobility potential, built environment
