基于现行汇率制度的外汇储备规模研究

What is the Optimal Forex Reserve given China's Current Forex Scheme

中国外汇储备近几年持续快速增长,到2005年7月汇率制度改革前外汇储备已经突破8000亿美元。汇改以后,外汇储备的上升势头依然没有得到遏制,截至2007年底,外汇储备已经突破15000亿美元,这样巨大的外汇储备规模引起了国内外的关注。高额外汇储备在提高中国经济实力和国际地位、保持人民币汇率稳定的同时,也对中国经济产生了负面影响,不利于经济健康稳定发展。因此对外汇储备规模进行研究,对外汇储备进行科学的管理,才能发挥其在我国宏观经济运行中的作用。本文以中国外汇储备规模为研究对象,探讨当前中国外汇储备的合理规模以及政策选择。本文比较有新意的地方在于:紧跟经济情况的变化,是对外汇储备最新现状的研究,也就是对在有管理的浮动汇率制度下的外汇储备规模的研究,并与在固定汇率制度与浮动汇率制度下的外汇储备规模进行了比较和分析;把外汇储备规模和汇率制度联系起来进行研究,着重论述由于汇率制度的变化会对外汇储备规模产生哪些影响;总结前人研究的成果,提出了一些自己的看法,使研究所考虑的因素尽可能的全面,包括汇率制度改革之后出现的一些新的因素,运用指标分析、计量分析以及定值分析进行实证分析,得出有理论依据的结论,并根据指标分析、计量分析以及定值分析得出的结果提出了有针对性的政策建议。
