    目的:研究人民币在澳门的流通情况,分析其流通可能受哪些因素的影响。方法:对澳门的人民币流通情况进行定性分析,并收集流通量数据和贸易量、博彩消费收入等数据,在ADF检验和协整检验后,建立误差修正模型,并进行Granger检验。结论:澳门对内地的贸易量、澳门从内地游客身上获得的博彩和旅游收入这两个因素将对人民币的流通量产生正面影响。而长期来看,人民币在澳门的流通情况可能还取决于内地直接投资、人民币汇率和澳门居民对人民币的信心。 OBJECTIVE: To discuss the current status of circulation of RMB in Macao, and to analysis the influence factors METHOD: Data has been collected, including RMB circulation, trade between mainland and Macao, gambling and lottery income from mainland.

  • 详情 基于Fourier分析的中国股市波动周期研究
    摘 要:本文应用Fourier方法对沪深两市波动周期进行实证分析,旨在揭示中国股市的周期性波动特征,为进一步研究我国资本市场的波动提供依据。最后得出,中国股市波动周期大约为16天,沪深两市日收盘价序列和周平均收盘价序列都是非平稳的,但却是一阶单整的,并且深市较之沪市有更强的周期性。
