By introducing the exogenous supply shock variable into Phillips Curve and adding asset prices (e. g. housing price and stock price) and the exogenous demand shock variable to IS Curve, this paper applies GMM method to estimate the extended IS-PC Model between 1996 and 2006. The empirical results show that housing price has a notable positive impact on the output gap, while share price doesn't have. Lastly, the article puts forward corresponding enlightenments.

本文在菲利普斯曲线的解释变量中引入外部供给冲击变童，在IS曲线中引入了房价、股价等资产价格和外部需求冲击变量，以我国1996-2006年的季度数据为样本、采用GMM方法佑计了扩展后的IS-PC模型，实证结果显示房价对产出缺口有显著的正向影响而股价对产出缺口的影响不显著，并在此基础上提出了相应的政策启示。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
