within the framework of permanent income hypothesis or life-cycle theory, this paper applies johansen co-integration test, granger causality test and ols regression method in the empirical analysis and comparison of the impacts of stock price and housing price on consumption of china in 1997-2006.the results show that the wealth effects is weak and the effects of housing is larger than that of stock, then corresponding enlightenments are put forward.

文章在持久收入假说或生命周期理论模型的框架下，运用johansen协整检验、granger因果检验和ols回归方法对1997—2006年股价和房价影响我国消费的效应及其大小进行了实证研究和比较分析，结果发现资产的财富效应较弱且房价对消费的效应大于股价的效应，最后提出了相应的启示。

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。
