摘 要:防范系统性金融风险历来是各国政府的重要任务之一。为了探究供给侧结构性改革是否有效降低了系统性金融风险,本文从风险传染视角出发,以供给侧结构性改革提出时间为节点,分成三个时间窗口运用ARMA EGARCH t模型和EVT POT模型对股票市场、外汇市场、债券市场的边缘分布进行建模,随后运用Vine Copula模型分析了金融子市场间相依性的变化。实证结果表明,供给侧结构性改革对于金融市场间的风险传染改善程度有限,对于系统性金融风险的降低还不明显。为了更好地凸显供给侧结构性改革的成效,适应新发展格局,我国应继续坚定不移地推进供给侧结构性改革的深化。

Abstract:Preventing systemic financial risks has always been one of the important tasks for governments. To explore whether supply side structural reform has effectively reduced the systemic financial risk, this paper embarks from the perspective of risk contagion, takes the time when the supply side structural reform are proposed as the node, and divides into three time window using ARMA EGARCH t model and EVT POT model on the edge of the stock market, foreign exchange market, bond market distribution model, then using the Vine Copula model analyzes the dependence between financial sub markets. The empirical results show that the supply side structural reform has limited improvement in risk contagion among financial markets, and the reduction of systemic financial risks is not obvious.In order to better highlight the effect of supply side structural reform and adapt to the new development pattern, China should continue to unswervingly promote the deepening of supply side structural reform.

Key words:systemic financial risk; supply side structural reform; dependence; copula

改革開放40多年以来,中国经济不断高速增长,取得了很多惊人的成就,已经成为了名副其实的经济大国。然而,中国经济进入新常态以来,供给端的生产成本优势在逐渐丧失,需求侧出现缺乏高质量投资、消费需求低迷等问题,这些结构性矛盾引起了经济的失衡。而传统对需求侧的管理是针对需求总量进行调控,不易深入至结构,具有相当的局限性。据此,中央适时提出了供给侧结构性改革,以“三去一降一补”为着力点,在供给侧对经济结构进行优化。其中去杠杆旨在降低我国各个经济部门的杠杆率。历史事件及文献表明,金融部门的高……
