文摘本文首先在理论分析的基础上建立时间序列向量自回归模型(V A R),然后选取指标分别对俄罗斯银行业发展与俄罗斯股票市场发展这两个变量进行代理,继而在最优滞后期的条件下建立俄罗斯银行业发展与贸易开放程度、俄罗斯股票市场发展与贸易开放程度两个向量误差修正模型(VECM),同时结合Grange因果检验的方法,分别对俄罗斯银行业发展与贸易开放程度、股票市场发展与贸易开放程度之间的关系进行了实证分析,并以此综合判断俄罗斯金融发展与贸易开放程度两者之间的关系。研究表明:在经济转轨过程中,俄罗斯金融体系的发展与贸易开放程度具有显著的线性关系,贸易开放程度的提高首先带动了俄罗斯金融体系的发展,俄罗斯金融体系的发展反过来又进一步促进了贸易开放程度的提高。
