摘要: 在世界银行公布2005年中国购买力平价(PPP)数据以后,国际社会提出了种种质疑,本文分别从我国价格水平变化和经济增长变化之间的关系、地区和城乡之间价格差异、代表性和可比性商品之间价格差异及其对PPP的影响,论证我国PPP数据的合理性。研究发现,我国PPP值和价格水平指数具有明显的宾大效应,即相对价格水平偏低,而随着经济快速增长,我国价格水平和PPP值呈较大幅度上升趋势。我国地区价格水平与当地经济发展水平之间相关度减弱,国内宾大效应不明显,地区之间、城乡之间、可比性和代表性之间产品价格差异较小,抽样分布对PPP影响有限。世界银行公布的2005中国PPP数据有其合理性。

关键词: 价格水平, 购买力平价, 宾大效应

Abstract: This paper would demonstrate the rationality of China’s PPP data in 2005 released by World Bank and respond many disputes over this result from international community. It explains the Penn Effect of the price level of China using Balassa-Samuelson effect, analyzes the price differences between urban and rural areas, between various types of products, and their influence on PPP based on a lot of statistics. The study shows that there is the obvious Penn Effect in China PPP data. In recent years China PPP and price level are rising sharply, in line with the actual situation in fast economic growth. The statistics also suggest the small domestic Penn Effect. The product and area samplings have limited impact on the PPP because of the little gaps of consumer prices between regions, rural and urban areas. The change trend of China’s PPPs data estimated by World Bank has its rationality in some extent.

Key words: Price level, PPP, Penn Effect
