本文运用动态因子模型和B-B算法,以1993q1-2008q3时间段内GDP季度数据为基础,考察了东亚十国(地区)共同经济周期及其具体特征。再根据动态因子模型得到的参数,比较了东亚各国(地区)和共同经济周期的相关性。我们发现,除中国和共同周期的关系不大,东亚其他国家(地区)和共同周期的关系比较紧密。 Based on the quarterly data of GDP in 1993q1-2008q3 period, the dynamic factor model and B-B algorithm are used in this paper to examine the common economic cycle and the specific characteristics of ten countries in East Asia. Based on the parameters obtained from the dynamic factor model, the correlations between East Asian countries (regions) and the common economic cycle are compared. We find that other countries and regions in East Asia have closer relations with the common cycle except for the fact that China has little to do with the common cycle.
