Abstract

摘要

Greener alternatives for fuelling automobiles, such as hydrogen transport and electric vehicles, have shown considerable promise in transportation. Many others are sceptical of the growing enthusiasm for these new technologies, believing that energy storage technologies and management are insufficient for a complete shift. Such a network of variables and smart grid technologies that can help with the transition may reveal some systemic hazards linked with financial institutions, company risk and failure, and so on. This study attempts to characterise spillovers and connections between the indices of green transportation, smart grid, innovative materials, energy storage, and energy management globally. To do this, we employ a novel strategy developed by Balcilar et al. (2021) as well as a robustness check using the well-known Diebold and Yilmaz (2012) method. The study highlights the sub-systemic sector's connections, giving policymakers insights into instruments to support financial market sustainability and stability. It would be critical to separate the impact of these indicators, but given the intrinsic relationship, this would be nearly impossible. The transportation innovation network is not rigid and established in its interconnection. The role of indicators shifts from transmitting to absorbing shocks regularly, and policymakers who want to encourage long-term solutions must be aware of this.

在交通运输领域，以氢气、电等更环保能源为燃料的汽车展现出巨大潜力，这些技术不断获得大众青睐，但仍有许多人对此持怀疑态度，认为目前的储能技术和管理无法应对这一全面转变。一系列的变量和智能电网技术推动该转变，揭示了与金融制度、企业风险和失败等相关的系统性风险。本研究旨在描述全球绿色交通、智能电网、新型材料、能源存储和能源管理等指标之间的溢出效应和连通性。为此，我们采用了Balcilar et al.（2021）等人提出的新策略，同时也采用了Diebold和Yilmaz（2012）的方法，检测稳健性。本研究凸显了子系统部门之间的联系，让政策制定者能够深入了解维持金融市场可持续性和稳定性的方法。虽然需要将区别这些指标产生的影响，但考虑到其内在联系，此法并不可行。交通创新网络不是刚性的，也不是建立于互联互通中的。这些指标从传导冲击转变为日常处理冲击，而若想得到长期解决方案，政策制定者必须意识到这一点。
