Basing on operation of China’s transnational enterprises, this paper aims to discuss the main influence factors of corporate brand and the impact that corporate brand has on consumers purchase intention from perspective of internationalization. The structure equation model is built with national brand image, products and service and customer communication as independent variables, corporate brand as the intervening variable and purchase intention as dependent variable. The empirical results show that corporate brand and national brand image both have effects on consumers purchase intention in the international market; among the three top factors, the factor of products and service in a company has the most important impact on corporate brand. Based on these conclusions, the paper also provides some managerial suggestions for implementing the brand strategies for China’s transnational enterprises and points out some future research aspects.
