摘要：中美物价现状存在很大差异。在商品中，无论是有形的还是无形的，中国大部分的商品价格已高于美国，而中国的平均工资却低于美国，在这种情况下便造成了我国的国民福利低于美国的国民福利。本文首先会通过比较中美的税收政策以及政府支出政策来分析造成两国物价差异的原因。在分析的过程中发现，由于中美两国税收政策的差异，使得中国的商品中所含有的税收远远高于美国，由此造成了中国商品的价格比美国的商品价格高。从政府支出这一财政政策来说，由于中国的转移支付政策补贴了出口的商品使得商品在国内价格较高而出口到美国价格较低。美国的政府购买政策使得美国的物价较低。然后从原因分析中归纳出美国物价对于中国物价的借鉴意义来改善中国的国民福利。比如中国在财政政策方面可以降低商品税以及减少商品税税种；而在货币政策方面可以提高利率以及提高法定准备金率。
