运用购买力评价理论分析中美农产品物价差异摘要中国已成为世界第二大经济体，在金融危机中中国经济一枝独秀，中国的经济实力大大扩展。
在这种情况下，拿中美两国比较就很常见了。
其中物价对比是比较常见的话题。
长期以来，中美物价差异问题都是学术界研究的热点问题。
人均可支配收入作为衡量居民收入基本情况的重要指标，也常被用于研究中美物价差异以及购买力方面。
然而，目前中美人均可支配收入的高低，以及差距的计算，都是基于名义价格来计算的，而中美农产品物价差异目前来看是有很大差异的。
由于中美农产品物价水平并不一致，同等数量的人民币以及美元的购买力也不相同，单纯地用名义价格来衡量中美农产品物价差异带来的购买力差异，就不足以反映各中美农产品物价的真实，从而无法找到原因解决问题。
由于受到购买力平价理论的启发，本文基于购买力平价理论，算出中美农产品的物价差异，用以剔除中美农产品价格差异，修正国际收入，核算真实的收入以及收入差距。
本文首先以消费价格指数为代表分析了价格差异现象，然后利用购买力平价的计算方法。
在这些研究的基础上，来探讨中美两国的农产品物价差异以及这种差异所产生的原因并提出实际的解决对策。
关键词：购买力平价理论；农产品物价；差异Using the theory of purchasing power parity to analyze the difference between China and AmericaAbstractWith the Chinese to become the world's second economy and in the financial crisis Chinese economy thriving, Chinese economic strength greatly expanded. In this case, take the Sino US comparison is common. The price comparison is a common topic. For a long time, Sino US spreads different problems are from a hot issue of academic research. The per capita disposable income as an important index to measure the basic situation of the residents' income were also used to study the price difference and purchasing power. However, currently in the United States per capita disposable income level, and the gap between the calculation is based on the nominal price is calculated, and the price difference of Sino US now there is a big difference as China and the United States. The price level is not the same, the same amount of RMB and the purchasing power of the dollar is not the same, simply to measure the price difference with the nominal price of Sino US Differences in purchasing power, it is not enough to reflect the true income level of the Chinese and American people, but also can not be truly measured to calculate the income gap between China and the United States.Due to the purchasing power parity theory of inspiration, this thesis based on the theory of purchasing power parity, calculated between the US and China Renminbi and dollar buying power index, to eliminate the differences between Chinese and American prices, the correction of international income, accounting income and the income gap. Firstly, this paper to the consumer price index as the representative of analysis the phenomenon of price difference, and then use the purchasing power parity calculation method. Through these studies, to find the price differences between CN and the USA,and this difference brought about by the impact is very useful.
