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。

The model is adopted to produce the inverse time overcurrent characteristic curves. In order to solve the problem of the inverse-time characteristic curve of exponential calculation into a microprocessor capable, this paper discusses it and puts forward solutions.
