This study was to observe how globalization has transformed the attitudes and behaviors of consumers especially in the emerging economy environment such as Malaysia. The aim of this article is to identify the differences in consumers’ product preference for products made in 4 different countries – Japan, Korea, Malaysia and China. Further, this article also aims to analyze how consumers’ ethnocentrism affects product preference as well as how the effect of ethnocentrism varies across products from different countries of origin and product involvement levels. Information for consumers’ product preference was collected through a structured questionnaire from the Malaysian consumers. Concentrating on 2 product categories from 4 different countries, the questions in the questionnaire particularly focused on three different levels of analysis; in addition, CETSCALE was used to measure consumer ethnocentrism. Finally, the hypotheses were tested using ANOVA and t-test statistics, etc. The results provided support for all of the hypotheses, thereby revealing the presence of significant differences in consumer product preference, which is engendered by country of origin, consumer ethnocentrism and product involvement level effect. The research results here have implications for future studies on the effects of country of origin and consumers’ ethnocentrism in developing countries. Moreover, the results also contributed to the validation of CETSCALE in a culturally diversified environment.
