gdp平减指数计算方法

GDP可以分为现价GDP与不变价GDP,真实GDP等于现价GDP除以GDP平减指数,然而在统计年鉴中,并没有直接给出GDP平减指数以及计算方法,下面我们对GDP平减指数的计算方法作以简要介绍:

GDP平减指数等于现价GDP除以不变价GDP,若1978年的指数为100,1979年的GDP指数为107.6,是指与1978年相比,按可比价计算,GDP增加了7.6%,1978年的GDP为3624.1,则按不变价计算,1979年的GDP等于3624.1乘以107.6等于3899.53,则1979年的平减指数为现价(1979)4038.2/3264.1=103.56,据此计算,则GDP平减指数及真实GDP如下表:

在一些计算中,一些文章喜欢算换成1990年为100的不变价计算真实GDP,此方法其实是假定1990年的指数为100进行计算,例如,1990年的现价GDP=18547.9,1990年的指数为

281.7,1996年的指数为544.1,则以1990=100,1996年的价格指数为

544.1/281.7*100%=193.1,则1996年不变价的GDP为1854.79*193.1%=35815.99,则1996年平减指数为67884.6/35815.99*100%=185.9,如此计算,可以得到1990=100的GDP平减指数,其计算结果如下表:
