The aim of this paper is to analyze the entry strategy of Spanish companies into the market, companies which have followed an implementation process in some emerging countries such as China, Brazil and Mexico. For this reason, a bibliographic revision has been made to determine internationalization methods as well as a field work based on polls applied to Spanish company executives that are implementing them in their developing economies. After that, a descriptive data analysis has been made. The outcomes of this research suggest that China and Brazil have more big entry barriers than Mexico for Spanish firms, and also these huge difficulties are reflected through the market entry method. In the first two former cases, joint ventures are usually applied, and in the other case, the establishment of subsidiaries is preferably applied. [ABSTRACT FROM AUTHOR]
