CPI通常被用来衡量一个经济的通货膨胀水平。一般而言,抑制通货膨胀是一个国家经济政策所希望追求的一个主要目标,然而这个目标能否成功实现,又受到政府政策的可信度和连贯性以及政府公信力的影响。本文认为,在这些因素中,增强政府公信力是有效控制CPI和控制通货膨胀进而增强经济政策有效性的一种现实途径。 The CPI is often used to measure the level of an economy’s inflation. In general, curbing inflation is a major goal that a country’s economic policies are pursuing. Whether this goal can be achieved successfully, however, is also affected by the credibility and coherence of government policies and the credibility of the government. This article argues that among these factors, enhancing government credibility is a realistic way to effectively control the CPI, control inflation and enhance the effectiveness of economic policies.
