This essay introduced the method and the empirical results of run test, Dickey-Fuller test and variance ratio test on the efficient market hypothesis. Furthermore, reviewed the volatility test method and empirical result on the EMH which relative to the tests based on stock market return.

摘 要：介绍了市场有效性假定的游程检验，DF检验以及方差比检验的方法和相关实证研究的结果，与以上基于股票市场收益的市场有效性检验相对应，对市场有效性假定的波动性检验方法以及实证结果进行了述评。

Using augmented Dickey-Fuller test, the result shows that BDI logarithm series is nonstationary but the first difference is stationary, i. e. it is integrated of order one. High-level ARCH effect was certification in the BDI logarithm series by ARCH LM test, and GARCH (1, 1) model was used to eliminate the conditional heteroscedasticity. Through variance ratio test, the result shows, that the random walk hypothesis of BDI logarithm series can be rejected and international dry bulk shipping market is inefficient.

运用ADF检验方法对BDI的对数序列进行平稳性和单整检验，结果证明BDI对数序列是一个非平稳过程，经一阶差分后是平稳过程，即BDI对数序列是一阶单整过程；通过ARCH LM检验认为BDI对数序列存在高阶ARCH效应，并用GARCH(1，1)模型消除了残差序列的条件异方差性；通过方差比检验法对国际干散货航运市场的收益率序列进行了检验，结果显示BDI的对数序列的随机游走假设被拒绝，国际干散货航运市场不是一个有效的市场。
