摘要CPI与PPI的关系一直是学者们研究的一个热点,他们认为,两个指数是可以互相取代的。然而,近些年来,在某些时期,PPI的波动非常大,这使得学者们原有的结论变得扑朔迷离。CPI与PPI之间是否真的存在着一定的关系?或者,二者之间存在关系的说法仅仅是人们的空想,与实际并不契合?我们觉得,有必要对CPI与PPI之间的关系进行再研究。在文中,我们使用了理论与实际相结合的方法,在理论描述的基础上,假设CPI与PPI之间具有相关关系,并利用SPSS软件对相关数据进行了处理,验证了相关假设,同时,对CPI与PPI之间的特殊现象——“倒挂”进行了简单观察研究。我们简单介绍了Granger检验在倒挂现象研究中的作用,描述了CPI与PPI之间的倒挂现象,并对“倒挂”现象出现的原因进行了分析,发现研究范围、传导环节、政府干预等是造成CPI与PPI出现倒挂现象的主要原因。89225

ABSTRACT The relationship between CPI and PPI has always been a hotspot in the research of the scholars, they think these two index can replace each other。In recent years, however, PPI become very volatile, which makes the scholars’ original conclusion is uncertain。Between CPI and PPI whether there exists a certain relationship?Or, relationship in between is just is the dream of people, and practice is not fit?I think, it is necessary to carry out the relationship between CPI and PPI study again。In this paper, the author USES the method of combining the theory with practice and on the basis of the theory of description, assuming that has the relationship between CPI and PPI, and making use of the SPSS software for data processing, verify the relevant assumptions, at the same time, the special phenomenon - between CPI and PPI "upside down" has carried on the simple observational study。The author simply introduces the Granger test method in the study of inversion phenomenon, describes the CPI and PPI between inversion phenomenon, and the cause of the "upside down" phenomenon are analyzed, found the research scope, transmission link, and the government intervention is one of the main reasons for the CPI and PPI appear upside down。源Y于U优I尔O论P文W网wwW.yOueRw.com 原文+QQ75201-8766
