In the longterm branding strategy, creating sequence between corporate brand and product brand is a dilemma due to limited resources. Previous researches documented perceptions of a company can influence product evaluation and purchase intent, but how and to what extent they will have remained unanswered.  The significant effects of corporate brand and product brand on purchase intention in experiments were tested empirically. Additionally，under more powerful corporate brand, the study further distinguished more significant effect on purchase intent under the same product brand. The findings show that customer's purchase decision rely more on corporate brand than on product brand in the current Chinese market and fill the empirical gap. The results also support theoretically creating priority between corporate brand and product brand.
