在人民币汇率双向波动幅度进一步加大的背景下,传统的个人外汇管理“总量分析+结构分析”模式,已难以摸清复杂数据背后的真实规律。因此,本文借助SAS软件的“ward聚类算法”,着重对陕西省个人购付汇重点关注主体进行聚类分析,从而为个人外汇业务形势分析及监测管理提供有效参考。

Under the background of the two-way volatility of the RMB exchange rate,the traditional model of individual foreign exchange management based on“volume analysis+structural analysis”has been facing challenges,which is unable to discover the true patterns behind complex data.To this end,by using SAS software tools,this paper uses the"ward clustering algorithm"of SAS software to analyze and characterize the main subjects of purchase and payment in shaanxi province,therefore,provides an effective reference for analysis and regulation.
