This paper aims to investigate the Granger causality relationship in quantile between the FinTech Index and globally systemically important banks (G-SIBs). The result was observed that at the median and under conditions of extreme quantiles in the FinTech Index, there was no Granger causality relationship between the FinTech Index and the vast majority of systemically important banks. Our research offered vital insights to regulatory agencies, highlighting the importance of monitoring market conditions at higher or lower quantiles to prevent the impact of financial technology on G-SIBs and to maintain global financial stability.

金融科技指数对全球系统重要性银行（G-SIB）的异质依赖性

本文旨在研究金融科技指数与全球系统重要性银行（G-SIB）之间分位数的格兰杰因果关系。结果发现，在金融科技指数的中位数和极端分位数条件下，金融科技指数与绝大多数具有系统重要性的银行之间不存在格兰杰因果关系。我们的研究为监管机构提供了重要见解，强调了以较高或较低分位数监测市场状况的重要性，以防止金融技术对 G-SIB 的影响并维持全球金融稳定。
