摘要: 审慎监管条件下,对系统性风险进行准确测度并识别风险演化特征是对证券公司实施风险管理的首要环节。采用SCCA技术,构建Gumbel Copula模型刻画证券公司间的风险相依结构,并对监测指标J-VaR进行了改进,解决了模拟中不易逼近最小边界的问题。从微观、宏观两个层面分别对单个证券公司及整个证券公司系统的风险进行了测度和演化特征分析。实证结果表明系统性风险在大规模爆发前往往会存在部分公司共同表现出的小型波动前兆;证券公司系统性风险具有"陡增缓降"的特点且在风险传导阶段形成的多次冲击对整个体系具有较大的破坏力。

Abstract: The crash of China's stock market in 2015 has aroused great attention to the systemic risk of securities market and especially securities companies. Under prudential supervision, accurate measurement of systemic risk and identification of risk evolution characteristics is the primary link to carry out effective supervision on securities companies. In this paper, by utilizing the SCCA technology, Gumbel Copula model is built to describe the risk dependence structure of different securities companies, and overcome the difficulty of boundary approximation in simulation by modifying the monitoring index J-VaR. The stock price and balance sheet data from 20 listed securities companies ranging from 2011-2016 are collected to measure the systemic risk of China's securities companies. Then the evolution characteristics of systemic risk is analyzed from the aspects of both micro level (i.e. risk of individual securities companies) and macro level (i.e. risk of the entire securities company system). Results show that there tends to be precursory fluctuations before large-scale outbreak. It is found that systematic risk has the characteristics of "steep rise and slow drop", and multiple shocks during the conducting period have great destructive power. The research findings provide suggestions for systemic risk regulation on securities companies.

Key words: systemic risk, securities companies, risk measurement, evolution characteristics, SCCA technology
