The choice market share gained by low tier brand promotion is larger than high tier brand in comparatively expensive product such as lap-top,cell phone etc.,while the opposite result will be acquired in some comparatively cheap product,e. g. shampoo.The results give significant implications on pricing tactics for marketers in Chinese market.

Key words: Market Share, High Tier Brand, Low Tier Brand, Discrete Choice Model, Multinomial Logit Model
