随着外汇储备规模的不断增加,国家外汇储备投资的风险偏好亦会发生相应的变化。借鉴J.H.Makin（1971）的方法,构建外汇储备币种结构配置理论模型,讨论在效用最大化的情况下,储备资产投资如何在安全性、流动性和盈利性三原则间进行权衡。假设外汇储备仅投资于美元和欧元两种币种资产,选取2000年初-2014年第三季度的10年期美国国债和欧元区公债季度数据,运用协整分析、格兰杰检验等方法进行的实证研究发现：储备货币在外汇储备中的比重与储备货币收益率及其三阶矩显著正相关,国家外汇储备投资总体而言是风险规避型的。
隨著外彙儲備規模的不斷增加,國傢外彙儲備投資的風險偏好亦會髮生相應的變化。藉鑒J.H.Makin（1971）的方法,構建外彙儲備幣種結構配置理論模型,討論在效用最大化的情況下,儲備資產投資如何在安全性、流動性和盈利性三原則間進行權衡。假設外彙儲備僅投資于美元和歐元兩種幣種資產,選取2000年初-2014年第三季度的10年期美國國債和歐元區公債季度數據,運用協整分析、格蘭傑檢驗等方法進行的實證研究髮現：儲備貨幣在外彙儲備中的比重與儲備貨幣收益率及其三階矩顯著正相關,國傢外彙儲備投資總體而言是風險規避型的。

The risk preference of a country＇s foreign exchange reserve investment will be affected by the assets scale of its foreign exchange reserve.Learning from the three utility function in J.H.Makin（1971）,the paper has established a theoretical model of currency structure of foreign exchange reserve investment which gives full consideration to safety,liquidity and profitability.Supposing foreign exchange reserve investment is only composed of dollar and euro assets,the paper has made an empirical study on the quarterly data of 10 year US treasury bonds and the euro zone bonds from Jan.,2000 to Sep.,2014.By using cointegration analysis and Granger test,we conclude that the proportion of a currency in foreign exchange reserve investment has a significant positive correlation to the investment return and the three order moment of the currency;and generally speaking,the official foreign exchange reserve investment is risk averse.
