摘　　要：受英国SG100邮票价格指数启发,借鉴股票价格指数的建立方法,运用中国邮票互动网上提供的邮票收盘价和成交量计算出了中国邮票月度价格指数.在此基础上,将邮票价格指数的超额回报与股票价格指数的超额回报进行资本资产定价模型回归,结果显示中国邮票投资并不能为股票投资者提供多元化的可能,但英国邮票投资给中国股票投资者提供了多元化的可能,产生了超额收益,分散了风险.We are inspired by British SG100 Stamp Price Index to build Chinese Stamp Price Index by ourselves. We make use of closing price and trading volume of stamps which are available online to calculate the monthly price indexes of Chinese stamps. The results of the Capital Asset Pricing Model regression of the monthly stamp index excess returns and the excess returns of stock indexes show that investing in Chinese stamp can＇t provide portfolio d/versification benefits for stock investors. Adding British stamps to Chinese stock portfolios can improve the investment performance of investors.
