社保基金是社会保障事业健康发展的物质基础,安全性和流动性是其投资的首要原则。全国社保基金作为一类特殊的、可以进入资本市场投资的社保基金,其风险管理显得尤为重要。针对全国社保基金投资组合风险测度研究不足的现状,提出了全国社保基金投资组合经流动性调整的市场风险(La-VaR)测度的pair-copula-GARCH-EVT模型。与传统的copula模型相比,pair-copula方法不仅考虑了维数的影响,而且还能灵活地选择 copula 的类型。实证研究表明,pair-copula 对社保基金经流动性调整的市场风险建模的效果优于传统的多维copula模型。
社保基金是社會保障事業健康髮展的物質基礎,安全性和流動性是其投資的首要原則。全國社保基金作為一類特殊的、可以進入資本市場投資的社保基金,其風險管理顯得尤為重要。針對全國社保基金投資組閤風險測度研究不足的現狀,提齣瞭全國社保基金投資組閤經流動性調整的市場風險(La-VaR)測度的pair-copula-GARCH-EVT模型。與傳統的copula模型相比,pair-copula方法不僅攷慮瞭維數的影響,而且還能靈活地選擇 copula 的類型。實證研究錶明,pair-copula 對社保基金經流動性調整的市場風險建模的效果優于傳統的多維copula模型。

Social security fund is the material basis of social insurance business’s development. Safety and liquidity are the first principles of social security fund investment. The risk management of National Social Security Fund, as a special fund that can be invested on the capital market, is particularly important. Aganist the inadequate research on the risk measurement of National Social Security Fund portfolio, the method of pair-copula-GARCH-EVT is proposed to measure the liquidity-adjusted market risk of investment portfolio. Compared with traditional multivariable copula model, pair-Copula model not only considers the influence of dimensions and but also can flexibly select the type of copula. The empirical research shows that the pair-Copula method is more accurate than traditional copula model in the aspect of measuring the liquidity-adjusted market risk of social insurance fund portfolio.
