你好,我想求助关于不变价折算的问题
我有主要年份地区生产总值,
| 1952 | 48.41 | 
| 1955 | 58.96 | 
| 1957 | 65.11 | 
| 1962 | 69.20 | 
| 1965 | 95.10 | 
| 1970 | 129.23 | 
| 1975 | 184.16 | 
| 1976 | 187.97 | 
| 1977 | 202.40 | 
| 1978 | 249.24 | 
| 1979 | 298.55 | 
| 1980 | 319.80 | 
| 1981 | 350.02 | 
| 1982 | 390.17 | 
| 1983 | 437.65 | 
| 1984 | 518.85 |

| 2003 | 12442.87 | 
| 2004 | 15003.60 | 
| 2005 | 18305.66 | 
也有地区生产总值指数,是按1952年=100可比价计算的,
| 1952 | 100.0 | 
| 1955 | 118.9 | 
| 1957 | 121.9 | 
| 1962 | 103.8 |

| 1977 | 297.9 | 
| 1978 | 371.3 | 
| 1979 | 415.9 | 
| 1980 | 436.0 | 
| 1981 | 483.3 | 
| 1982 | 530.9 | 
| 1983 | 596.1 | 
| 1984 | 689.8 | 
| 1985 | 809.2 | 
| 1986 | 893.1 | 
| 1987 | 1013.2 | 
| 1988 | 1211.6 | 
| 1989 | 1241.7 | 
| 1990 | 1303.9 | 
| 1991 | 1412.1 | 
| 1992 | 1773.4 | 
| 1993 | 2124.4 | 
| 1994 | 2474.3 | 
| 1995 | 2855.3 | 
| 1996 | 3204.5 |

| 1998 | 3982.8 | 
| 1999 | 4384.8 | 
| 2000 | 4848.4 | 
| 2001 | 5340.5 | 
| 2002 | 5963.5 | 
| 2003 | 6775.9 | 
| 2004 | 7775.4 | 
| 2005 | 8901.2 | 
现在我想按1978年不变价计算,1995年2005年的地区生产值,怎么算?
