  on Main Statistical Indicators | 
| Retail
  Price Index  reflects the general
  change in retail prices of commodities. The change and adjustment in retail
  prices directly affect the living expenditure 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 calculation of retail price index is useful to analyze the
  changes of the above economic activities.  | 
| Consumer
  Price Index  reflects the trend and
  degree of changes in prices of consumer goods and services purchased by urban
  and rural residents, and is a composite index derived from the urban consumer
  price index and the rural consumer price index. Consumer price index can be
  used to analyze the impact of consumer price change on actual expenditure for
  living cost of urban and rural residents.  | 
| Urban
  Consumer Price Index  reflects the trend and
  degree of changes in prices of consumer goods and services purchased by urban

  workers.  |

  of investment in fixed assets. The investment in fixed assets consists of
  three components, namely the investment in construction and installation, 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
