2008年的金融危机对世界经济产生深远的影响,各国对于金融危机预警模型的研究也十分重视。基于结构方程模型中的MIMIC模型建立金融危机预警系统,并利用中国有关数据进行实证研究。根据模型的修正结果得到影响中国危机强度的5个变量,并通过计算得到"危机强度"的得分。由实证研究结果可知,中国金融市场在20世纪90年代波动比较剧烈,而2008年金融危机对中国金融市场的影响相对不大。

multiple waves of coronavirus disease 2019(COVID-19) outbreaks have affected numerous countries worldwide. The first case of SARS-CoV-2 reinfection was reported in Hong Kong in August 2020^([1]), leading to increased interest in the effectiveness of natural immunity acquired from primary infection. While data reports vary across countries, all findings indicate that prior SARS-CoV-2 infection provides substantial protection against reinfection^([2]). However, natural immunity from infection with previous non-Omicron or early Omicron sub-lineages offers lower levels of protection against Omicron reinfection, with rates below 60%^([3]) and approximately 75%[4], respectively.
