Explanatory Notes on Main Statistical Indicators

Comparable Prices refer to prices that are used to remove the factors of price change in calculating economic aggregates, so as to facilitate comparison of aggregates over time. Two methods are used for calculating economic aggregates at comparable prices：1．Multiplying the output of products by their constant prices of certain year；2．Deflation of data at current prices by relevant price index．

Constant Price refers to the average price of a given product in certain year, which is used for comparison of output value over time．As the output value at constant prices removes the factor of price changes，it reflects the trend of production development over time．Since 1949，with the changes in general price level，the State Statistical Bureau has issued nationally unified constant prices five times：the 1952 constant prices for 1949-1957；the 1957 constant prices for 1957-1971；the 1970 constant prices for 1971-1981；the 1980 constant prices for 1981-1990；and the 1990 constant prices have been used since 1991．

Average Annual Growth Rate Two methods for calculating average annual growth rate are applied in China，one is often called “level approach＂or the method of calculating geometric average，which is derived by comparing the level of the last year of the interval with that of the beginning year；the other is called “accumulative approach＂or algebraic average or equation method，which is derived by the summation of the actual figure of each year in the interval divided by the figure in the base year．

Usually the results calculated by the two methods are fairly close，but they differed sharply when uneven economic development occurred with striking fluctuations in growth．

The average annual growth rates listed in this statistical yearbook are calculated by “level approach＂except for the growth rate of investment in fixed assets．The base years are not listed when the years are listed for average annual growth rates. For instance，the average annual growth rate of 43 years since 1949 is listed as average annual growth rate of 1950-1992 without listing the base year 1949．And the analogy of this is also the same for the rest of the years．

Various Planning Periods The conventional division of "time period" in this yearbook is as follows: Economic Rehabilitation Period，1950-1952；The first five-year plan period, 1953-1957；the second five-year plan period, 1958-1962；the third five-year plan period，19661970；the fourth five-year plan period，1971-1975；the fifth five-year plan period, 1976-1980；the sixth five-year plan period，1981-1985；the seventh five-year plan period，1986-1990；the eighth five-year plan period，1991-1995; and the ninth five-year plan period, 1996-2000．
