不同汇率制度下汇率传递时滞的实证分析——基于中国、日本、巴西、阿根廷四国数据

本文采用向量误差修正模型及脉冲响应函数,选取中国、日本、巴西和阿根廷作为样本,运用1996-2009年的季度数据,分别对四国的汇率传递时滞进行实证分析。研究表明:不同汇率制度下,汇率变动对国内物价水平的影响存在差异,汇率传递均存在时滞。固定汇率制度下,汇率传递效应的时滞更长;在相对浮动的汇率制度下,汇率传递的时滞相对较短。本文样本中,中国的汇率传递时滞最长,为18个月。因此,在人民币汇率制度改革过程中,确定汇率波动区间以及考察汇率政策效果时,需要考虑汇率波动对国内物价影响时滞的长短。同时,受我国外汇市场化程度的影响,货币当局应当合理引导汇率预期,以适应货币政策目标的需要。

Empirical Analysis of Exchange Rate Pass-through Lag under Different Exchange Rate Regimes:Based on the Data of China,Japan,Brazil and Argentina

By using the vector error correction model and impulse responses function,this paper empirically analyses exchange rate pass-through lag with the seasonal data of China,Japan,Brazil and Argentina in 1996-2009.The empirical result indicates that,(1) under different exchange rate regimes,the impact of exchange rate changes on domestic price levels can be positive or negative,and the exchange rate pass through lag exists.(2) Difference of exchange rate pass through lag exists in the four countries.And the lag ...
