Recent years it has leaded to many relevant studies from different perspectives that Chinese consumers' Purchase intention to Korean cosmetic products has been continuously increasing. Most of these studies looked into this phenomenal issue primarily based on the application of the TPB(the Theory of Planned Behavior), few on the extension of the TPB. Therefore the extension along the explaining construct of the TPB is applied in this study, beginning with the derived factors from reviewing previous studies. These factors are confined into the ones which are under control of Korean cosmetic companies, but not of Chinese consumers who are consuming or will purchase Korean cosmetic products. It has to be mentioned that although these strategic factors are not included in the TPB, they participate in the building up of the whole explaining construct of the TPB. Consequently, marketing practice, consistency between marketing practice and product attribute, and authenticity of product are identified and conceptualized as strategic factors after reviewing previous relevant studies. Then there are two prediction models developed to mediate Chinese consumers' intention to purchase Korean cosmetic products by distinguishing the first purchase of Korean cosmetic products. Finally two propositions were made for Korean cosmetic companies to promote Chinese cosmetic consumers' purchase intention.
