  1. Responding to the changes in the statistical environment
    Changes in the statistical environment:

    1. Enriched supply-side statistics, especially in the service sector
    2. Constraints on the demand-side estimation
      • Increased importance of consumer spending for those with rare intervals but large value, and individualization of household
      • Possible diversification in firm behaviour


      More comprehensive estimation by taking count of wide range of supply-side statistics in addition to demand-side statistics

  2. Earlier estimation that would help timely policy decisions.

    The timing, now about two months and 7 days after the quarter, will become earlier by nearly a month, comparable to other developed countries.

  3. Improved Accuracy
    • Estimation consistent to that for annual accounts
    • Rate of increase over the previous quarter is given priority
      ( rate of increase over a year ago, under the present system )
    • Flexible revision and concurrent seasonal adjustment to represent recent trend
