摘要:

随着全球金融一体化程度的不断深化,防范极端金融风险的跨市场传染成为了各国政府和学术界加倍关注的重要议题。本文首先拓展经典的条件自回归风险价值模型,然后测度中国、印度、俄罗斯等20个新兴市场国家间股市极端风险的跨市场传染强度,并采用伪分位数脉冲响应函数研究中国与其他主要新兴市场国家间股市极端风险跨市场传染的动态演变过程。研究结果显示:新构建模型能有效地测度中国与其他新兴市场国家间股市极端风险的跨市场传染效应,并能较好地拟合2008年金融危机、2013年欧洲债务危机、2015年中国“股灾”等极端事件对股市带来的冲击;中国与其他大多数新兴市场国家股市间具有不对称的极端风险传染效应,但与印度尼西亚、印度、新加坡、南非4个国家股市间具有双向的极端风险传染,并且负向冲击的影响更大;中国股市更易受到来自亚洲和非洲地区新兴市场的极端风险冲击。这些研究结论可为防范和化解跨市场的极端风险,保障和维持我国金融市场的稳定和健康有序发展提供理论分析与实证检验的参考依据。

Abstract:

Within the framework of economic globalization, an intensifying interconnectedness among financial markets has been observed, particularly exacerbated by the aftermath of the 2008 global financial crisis. The phenomenon of financial risk contagion across geographical boundaries has garnered considerable scholarly and regulatory scrutiny on a global scale. Emerging markets have ascended as pivotal engines propelling global economic expansion, a big number of international investors has been focused the China’s financial markets, which have emerged as a focal point within the emerging markets sphere. Meanwhile, the other emerging markets will boost their external openness to improve the efficiency in terms of asset allocation. Against this contextual tapestry, empirical investigation into the cross-market transmission of extreme risks amongst China and other preeminent emerging equity markets serves a dual purpose: elucidating the mechanistic pathways of extreme risk propagation and furnishing vital theoretical underpinnings along with strategic directives aimed at forestalling and mitigating such perils, thereby safeguarding and nurturing the stability and robust, orderly progression of our nation's financial markets.The scholarly contribution of this paper is twofold (1) It examines the interconnectedness between the Chinese and other principal emerging market equities from a tail-risk perspective, thereby augmenting the extant literature on mean and volatility spillovers across stock markets; (2) To ascertain the asymmetric influences of positive and negative market shocks on tail-risk transmission, the MVMQ-CAViaR model is adapted to incorporate asymmetry, formulating an Asymmetric MVMQ-CAViaR model. This refined approach facilitates an in-depth scrutiny of the cross-market contagion dynamics of extreme risks among China and other major emerging market equities. The significance of these extreme risk contagion effects is empirically assessed using constructed Wald tests, with quantile impulse response functions subsequently employed to unravel the underlying transmission mechanisms of extreme risk among equity markets.

Key words: emerging markets, asymmetrical MVMQ-CAViaR model, extreme risk spillover
