Abstract

This study investigates the influence of transport infrastructure, income inequality, information and communication technology on transport-oriented household expenditures. For this purpose, we chose the data set period from 1997 to 2021 for the 24 OECD countries and employed the cross-sectional auto-regressive distributed lagged (CS-ARDL) approach. Therefore, the outcomes reveal that income inequality drastically upsurges transport-oriented household expenditures, especially the pre-tax income share of the 100th percentile concentration of the super-rich. Besides, there is a convex relationship between income inequality and household expenditures. The magnitudes of information and communication technology (ICT) are negative and significant, implying that ICT reduces transport-related household expenditures by allowing them to access real-time information and choose their destination as well as travel modes from the comfort of their own homes. Also, the combined effect of income inequality and ICT reduces transport-related household expenditures in the sample countries. Thus, the findings recommend some policy implications and direct future research directions based on empirical evidence.

估算收入不平等、信息通信技术和交通基础设施对以交通为导向的家庭支出的影响

本研究探讨了交通基础设施、收入不平等、信息和通信技术对以交通为导向的家庭支出的影响。为此，我们选择了 24 个经合组织国家 1997 年至 2021 年的数据集，并采用了横截面自回归分布滞后（CS-ARDL）方法。因此，研究结果显示，收入不平等会大幅增加以交通为导向的家庭支出，尤其是集中在超级富豪的第 100 百分位数的税前收入份额。此外，收入不平等与家庭支出之间存在凸性关系。信息和通信技术（ICT）的大小为负且显著，这意味着信息和通信技术允许家庭在舒适的家中获取实时信息、选择目的地和出行方式，从而减少了与交通相关的家庭支出。此外，收入不平等和信息与通信技术的综合效应也降低了样本国家与交通相关的家庭支出。因此，研究结果提出了一些政策影响，并根据经验证据指明了未来的研究方向。

期刊介绍： In our first issue, published in 1972, we explained that this Journal is intended to promote the free and vigorous exchange of ideas and experience among the worldwide community actively concerned with transportation policy, planning and practice. That continues to be our mission, with a clear focus on topics concerned with research and practice in transportation policy and planning, around the world. These four words, policy and planning, research and practice are our key words. While we have a particular focus on transportation policy analysis and travel behaviour in the context of ground transportation, we willingly consider all good quality papers that are highly relevant to transportation policy, planning and practice with a clear focus on innovation, on extending the international pool of knowledge and understanding. Our interest is not only with transportation policies - and systems and services – but also with their social, economic and environmental impacts, However, papers about the application of established procedures to, or the development of plans or policies for, specific locations are unlikely to prove acceptable unless they report experience which will be of real benefit those working elsewhere. Papers concerned with the engineering, safety and operational management of transportation systems are outside our scope.
