  3. Overview • 1997, Method of Quarterly GDP Estimation of China • 2000, Method of Quarterly GDP Estimation ; • 2004, Some Complementary Regulation for Quarterly Regional GDP Estimation • 2006, Method of Quarterly GDP Estimation (tentative)

  4. Improvement in recent years Study the method of calculating Chain growth • 1. Develop X-12-ARIMA-NBS • NBS and Nankai University jointly organize Technique Group,Benefit from experiences of OECD and Statistics Canada • Base on X-12-ARIMA • Take into account Chinese factors, such as moving holidays, Effect of change of working days since 1995; Effect of “Goldenweek” holidays since 2000; Effect of adjusting working day for “Goldenweek” holidays

  5. Chinese factors • Effect of Moving Holidays: • There areSpring Festival, Mid-autumn Festival, Qingming Festival and Dragon boat Festival. Their effects are reflected by the relevant variables

  7. Chinese factors • Effect of golden week • Golden week is appeared in Oct. 1999.  As the name implies, golden week is a seven-days holiday which consists of nation holiday/labor holiday/spring festival and its adjacent weekend. This effect is adjusted by relative variables.

  8. Chinese factors • Effect of working days shift • In order to make the golden week seven days, sometimes we need to exchange several working days with weekend. Obviously, it will change the effect of working days and trading days. For this reason, we redefined the relative variables of trading days.

Statistical period is not complete in practice. for example, one month usually missed in service sector survey.

  13. Improvement in recent years • d. The length of time series is not enough • e. Master seasonal adjustment technique as soon as possible • f. Chain growth and Growth year on year, which one is dominant? • g. Whether annualized or not?
