摘要翻译：
本文论证了Bollerslev和Engle(1993)提出的协同持久性理论的缺陷，这些缺陷导致该理论难以应用。本文通过引入衰变系数的半衰期作为持久性的度量，并结合方差中持久性和协同持久性的弱定义，尝试用穷举搜索算法求解协同持久性向量来解决这一问题。此外，本文还对10个欧洲国家股票收益率波动的共持续性进行了实证研究。

英文摘要：
This paper demonstrates the flaws of co-persistence theory proposed by Bollerslev and Engle (1993) which cause the theory can hardly be applied. With the introduction of the half-life of decay coefficient as the measure of the persistence, and both the weak definition of persistence and co-persistence in variance, this study attempts to solve the problems by using exhaustive search algorithm for obtaining co-persistent vector. In addition, this method is illustrated to research the co-persistence of stock return volatility in 10 European countries.
