The research investigates the correlation between FinTech innovation and the index of renewable energy volatility from May 1, 2019, to October 28, 2022, by utilizing cutting-edge multiple wavelet analysis (MWA) techniques, including coherency and gain of partial wavelets. FinTech innovation and the green energy sector exhibit multiple coherencies. These coherencies suggest that three cycles, spanning from January 2020 to June 2020, December 2020 to April 2021, and January 2022 to May 2022, were focused on the high-frequency spectrum (3–68 days). Meanwhile, the other cycles were focused on low frequencies (69–130 days), which coexisted between June 2019 and January 2021 and January 2022 and October 2022. Green bonds and FinTech innovation's partial coherency indicate that modifications to the green bond markets caused shifts in FinTech innovation between June and November of 2019. FinTech innovation is in sync with green bonds pushing from December 2021 to October 2022. The partial consistency of FinTech innovation and sustainable energy demonstrates that both metrics align with the current FinTech innovation cycle, pushing from May 2019 to August 2019 and from December 2020 to July 2021, and both indicators are in sync with ARKF pushing. We also demonstrate how unexpected events like the Ukraine-Russia conflict and the COVID-19 epidemic affect these dynamic connectednesses. Hence, our paper calls for policy designs that promote the role of FinTech development in stabilizing the renewable energy market.

战争时期金融科技创新发展对可再生能源波动的动态溢出影响:小波模型的新见解

该研究利用尖端的多小波分析(MWA)技术,包括部分小波的相干性和增益,调查了2019年5月1日至2022年10月28日期间金融科技创新与可再生能源波动指数之间的相关性。金融科技创新和绿色能源领域表现出多重一致性。这些一致性表明,从2020年1月到2020年6月、2020年12月到2021年4月、2022年1月到2022年5月的三个周期都集中在高频频谱(3-68天)。与此同时,其他周期主要集中在低频(69-130天),这些周期在2019年6月至2021年1月以及2022年1月和2022年10月期间共存。绿色债券和金融科技创新的部分一致性表明,绿色债券市场的调整导致了绿色债券市场的变化。 2019 年 6 月至 11 月期间的金融科技创新。金融科技创新与 2021 年 12 月至 2022 年 10 月推动的绿色债券同步。金融科技创新和可持续能源的部分一致性表明,这两个指标都符合当前的金融科技创新周期(从 2019 年 5 月开始)至2019年8月和2020年12月至2021年7月,两个指标均与ARKF推送同步。我们还展示了乌克兰-俄罗斯冲突和 COVID-19 疫情等意外事件如何影响这些动态联系。因此,我们的论文呼吁制定政策,促进金融科技发展在稳定可再生能源市场中的作用。
