分别利用消除趋势法、增长率推算法和生产函数法测算中国1952~2008年的潜在产出和产出缺口。测算结果表明,1952~2008年间,中国产出缺口出现了波动水平正负交替的古典周期情形,改革开放前的波动程度高于改革开放后,1995年前的波动程度高于1995年后。通过分析比较这三种测算方法各自的优缺点,得以测算出历次宏观经济波动的起止时期,这将为分析历次宏观经济波动的形成原因打下必要的基础。
This paper uses three methods to estimate China's potential outputs and output gap from 1952 to 2008. The estimate results show that from 1952 to 2008, China's output gap was the classical cycle, the volatility was higher before the opening up, also before 1995. By analysis and comparison of these three methods, this paper researches the start and the end of macroeeonomic volatility, which makes the necessary foundation of the causes of macroeconomic volatility.
