在美国宽松货币政策对金砖国家的货币供应量具有联动性的基础上,分析了发展中国家发生通货膨胀的原因,并运用脉冲响应和方差分解对次贷危机后中国通货膨胀的主要原因进行分析,实证分析表明中国通货膨胀产生的根源在于其自身的经济增长。因此,在美国量化宽松货币政策的环境下,中国解决自身通胀问题的根本途径就是要防止经济增长过快,抑制投资需求膨胀,同时提高汇率和利率机制来维持国内的物价水平稳定。 Based on the linkage between loose monetary policy in the United States and the BRICS countries, the paper analyzes the causes of inflation in developing countries and uses impulse response and variance decomposition to analyze the main causes of inflation in China after the subprime mortgage crisis Analysis and empirical analysis show that the root cause of China’s inflation lies in its own economic growth. Therefore, under the circumstance of the United States’ quantitative easing monetary policy, the fundamental way for China to solve its own inflation problem is to prevent excessive growth, curb investment demand and increase exchange rate and interest rate mechanism so as to maintain stable domestic price level.
