Explanatory Notes on Main Statistical Indicators
Retail
Price Index
reflect the trend and degree of change in retail prices of commodities
during a given period. The change in retail prices of commodities directly
affect the living expenses of urban and rural residents, government revenue,
purchasing power of residents and the equilibrium of market supply and demand,
and the ratio of consumption to accumulation. Therefore, the retail price
indices are useful from an oblique perspective for observing and analyzing the
changes of the above economic activities.
Urban
Consumer Price Index
reflect the trend and degree of changes in prices of consumer goods and
services purchased by urban households during a given period. It can be used to
observe and analyze the impact of price changes in consumer goods and services
on wages (in monetary terms) of urban staff and workers, and provide a basis
for research on the livelihood of staff and workers and policy-making
concerning wages.
Price
Index of Investment in Fixed Assets
reflects the trend and degree of changes in prices of investment in fixed
assets during a given period. The investment in fixed assets consists of three
components, namely the investment in construction and installation, the
investment in purchases of equipment and instrument, and the investment in
other items. Price index of investment in fixed assets is calculated as the
weighted arithmetic mean of the price indices of the three components of
investment in fixed assets. Removing the factor of price change in the
aggregates of investment at current prices, this indicator shows the changes in
the prices of commodities and fees involved in the investment of fixed assets,
and can be used to observe the actual size, growth, structure, and efficiency
of investment in fixed assets and provides reliable and scientific data for
government planning, management, decision making, and further improving the
current national accounting system.
Producer
Price Index of Industrial Ex-factory Products
reflects the trend and degree of changes in general ex-factory prices of all
industrial products during a given period, including sales of industrial
products by an industrial enterprise to all units outside the enterprise, as
well as sales of consumer goods to residents. It can be used to analyze the impact
of ex-factory prices on gross industrial output value.
Producer
Price Index of Industrial Purchase
reflects the trend and degree of changes in purchasing price of raw
material, fuel and power paid by industrial enterprises when they purchase
production as input from the market or other energy and raw material producers
during a given period, and provide basis for measuring the material consumption
of industrial enterprises after removing influence of price from cost.
