Abstract

This research reaffirms a sustainable transport investment should go forward in a way that enforces consistent economic growth while maintaining environmental benefit. Society’s economic input-output relations reinvest the time saved by the transport system, of which benefit appeared as the income level’s rise. This research empirically proves that the recursive profit is possible when the infrastructure aligns accessibility enhancement with industries’ productivities. Specifically, we found that the interactions between industries and accessibilities make synergy when the industries maintain appropriate productivity. Under the same context, the measure for the socially vulnerable should start at capacity building even given transport, based on which we can build economically equitable accessibility. This research takes environmental sustainability granted as long as the incumbent Korean infrastructure investment principle exists without empirical analysis. A comparative analysis using structural equation models proved the existence of the synergy due to the accessibility-industry interactions. Besides, we captured the quantities of the synergy through groups of partial cross-sectional correlations. Authors conclude that government authority needs to pursue the best synergy between transport plan and economic development strategy, and prepare a capacity building for the socially vulnerable furthermore.

交通可达性和经济增长:对可持续交通基础设施投资的影响

摘要

这项研究重申,可持续的交通投资应该以一种在保持环境效益的同时促进经济持续增长的方式进行。社会的经济投入产出关系将交通系统节省的时间再投资,其收益随着收入水平的提高而显现。本研究实证证明,当基础设施将可达性增强与行业生产力相结合时,递归利润是可能的。具体而言,我们发现当行业保持适当的生产力时,行业和可访问性之间的相互作用会产生协同作用。在同样的背景下,针对社会弱势群体的措施应该从能力建设开始,即使是在交通运输的情况下,我们可以在此基础上建立经济上公平的可达性。只要现有的韩国基础设施投资原则在没有实证分析的情况下存在,本研究就认为环境可持续性是肯定的。使用结构方程模型的比较分析证明了由于可达性-行业相互作用而产生的协同作用。此外,我们通过部分横截面相关性组捕获了协同作用的数量。作者得出结论,政府当局需要寻求交通计划和经济发展战略之间的最佳协同作用,并进一步为社会弱势群体准备能力建设。使用结构方程模型的比较分析证明了由于可达性-行业相互作用而产生的协同作用。此外,我们通过部分横截面相关性组捕获了协同作用的数量。作者得出结论,政府当局需要寻求交通计划和经济发展战略之间的最佳协同作用,并进一步为社会弱势群体准备能力建设。使用结构方程模型的比较分析证明了由于可达性-行业相互作用而产生的协同作用。此外,我们通过部分横截面相关性组捕获了协同作用的数量。作者得出结论,政府当局需要寻求交通计划和经济发展战略之间的最佳协同作用,并进一步为社会弱势群体准备能力建设。
