The Summarizing Analysis And New Reflection On Purchasing Power Parity

Purchasing Power Parity is a classical theory about exchange rate research which is recognized by us. We can say that PPP theory is the influential one among the numerous theories. Once exchange rate was unbalanced essentially because of war, inflation or other factors we would pay more attention to this theory.But at the same time, during the past decades of years, the debatement about the validity of PPP theory never stopped. So many scholars home and broad have gone deep in this theory and have driven it forward. But until now, the build-up and development of Purchasing Power Parity have not been concluded integrally, roundly and detailedly.This text exactly proceeds from origin of this classical theory, take historical train of thought as the thread, detail the whole course of its development, know different science to the purchasing-power-parity theory , form the " authoritativeness " survey materials of a purchasing-power-parity theory development.The focal point of the article lies in forming and developing exhaustive argumentation and new to various kinds of this theory hypothesis validity production the purchasing-power-parity theory on this basis of gradual progress course thinking. For make article being full and accurate overall, I collect China and foreign various kinds of argumentation materials about the purchasing-power-parity theory, and refine, summarize, form a clear system of train of thought about this theory development finally. Meanwhile, the end in the thesis, this text also put forward doubt to the validity and feasibility of the purchasing-power-parity theory from different visual angles, the settlement of the doubt could make the purchasing-power-parity theory develop and perfect further , can enable its calculating in exchange rate and the policy guidance is had even more too it rational and accurate, and this is exactly what using value of this text is all about.
