贸易顺差、资本流入与中国外汇储备规模增长

本文通过协整检验和Granger因果关系检验,对影响我国外汇储备规模快速增长的诸因素进行了实证分析。分析结果表明,（1）我国外汇储备规模与年出口额、外国证券投资、外商直接投资、外债还本付息额具有长期的稳定关系。（2）年出口规模与外汇储备规模之间具有单向因果关系,是造成外汇储备快速增长的主要原因。（3）外商直接投资、外国证券投资和外汇储备规模具有正向相关关系,其影响强度较弱;而外债还本付息额与外汇储备呈负向相关关系。（4）1986年～2009年间,贸易顺差对外汇储备规模增长的贡献度约为68%,而资本流入约为32%。本文基于实证分析结果认为,采取贸易项目收支平衡战略以减少外汇储备过度增长是最佳的选择。
