gdp平減指數計算方法

gdp平減指數計算方法GDP可以分為現價GDP與不變價GDP,真實GDP等于現價GDP除以GDP平減指數，然而在統計年鑒中，并沒有直接給出GDP平減指數以及計算方法下面我們對GDP平減指數的計算方法作以簡要介紹GDP平減指數等于現價GDP除以不變價GDP，若1978年的指數為100,1979年的GDP指數為107.6,是指與1978年相比，按可比價計算GDP增加了7.6%,1978年的GDP為3624.1,則按不變價計算,1979年的GDP等于3624.1乘以107.6等于3899.53,則1979年的平減指數為現價(1979)4038.2/3264.1=103.56據此計算，則GDP平減指數及真實GDP如下表：年份現價GDP1978=100的指數不變價GDP平減指數真實GDP19783624.10100.003624.10100.003624.1019794038.20107.603899.53103.563899.5319804517.80116.004203.96107.474203.9619814862.40122.104425.03109.884425.0319825294.70133.104823.68109.764823.6819835934.50147.605349.17110.945349.1719847171.00170.006160.97116.396160.9719858964.40192.906990.89128.236990.89198610202.20210.007610.61134.057610.61198711962.50234.308491.27140.888491.27
