Abstract: As a new source of statistical data, scanner data have great advantages in the compilation of CPI. Foreign statistical departments have attached great importance to the study and application of this new source of data from the very first. In this paper, the experience of four countries using scanner data to compile CPI is studied, including Netherland, Norway, Switzerland and Sweden. Besides, this paper selects the cheese and beer groups as the research objects and compiles the elementary aggregates indexes using the Jevons and T?rnqvist equations，and the compilation results are compared with the RYGEKS which is regarded as benchmark index. The results are as follows: monthly chained Jevons price index has a downward large bias comparing with RYGEKS index, while monthly chained T?rnqvist index has a relatively small deviations comparing with RYGEKS in uncertain direction. Whether the bias is downward or upward relates to not only the choice of compiling formula, but also the characteristics of the products. In addition, according to the developed countries’ compilation experience and the findings in this paper, some recommendations are made about compiling CPI with scanner data in China.
