ABSTRACT

The rise of e-commerce has led to substantial changes in personal travel and activities. We systematically reviewed empirical studies on the relationship between online shopping and personal travel behaviour. We synthesised and assessed the evidence for four types of effects on various travel outcomes, including trip frequency, travel distance, trip chaining, mode choice, and time use. In 42 articles reviewed, we found more evidence that online shopping substitutes for shopping travel. Most studies to date have focused on trip frequency but neglected other travel outcomes. Very few studies have considered the modification effect, which has significant implications for travel demand management. In sum, previous studies have not reached a consensus on the dominant effect of online shopping, in part due to the diversity in variable measurements, types of goods, study areas, and analytic methods. A limitation of previous studies is the reliance on cross-sectional surveys, which hinders the distinction between short- and long-term behaviours and between modification, complementarity, and substitution effects. Our study provides an agenda for future research on this topic and discusses policy implications related to land use, behavioural changes, data collection, and modelling for practitioners who wish to incorporate e-commerce in planning for sustainable urban systems.

摘要

电子商务的兴起导致个人旅行和活动发生了重大变化。我们系统地回顾了关于网上购物和个人旅行行为之间关系的实证研究。我们综合并评估了对各种旅行结果的四种影响的证据，包括旅行频率、旅行距离、旅行链、模式选择和时间使用。在审查的 42 篇文章中，我们发现更多证据表明在线购物可以替代购物旅行。迄今为止，大多数研究都集中在旅行频率上，而忽略了其他旅行结果。很少有研究考虑修改效应，这对旅行需求管理具有重要意义。总而言之，以前的研究尚未就在线购物的主导效应达成共识，部分原因在于变量测量的多样性，商品类型、研究领域和分析方法。先前研究的一个局限性是对横断面调查的依赖，这阻碍了短期和长期行为之间以及修改、互补和替代效应之间的区别。我们的研究为该主题的未来研究提供了议程，并讨论了与土地利用、行为变化、数据收集和建模相关的政策影响，这些政策影响希望将电子商务纳入可持续城市系统规划的从业者。
