PurposeThe purpose of this study is to evaluate the influences of expatriate characteristics, complexity of task assignment and perceived cross‐cultural differences on needs for expatriate training, and expatriate training effectiveness and to evaluate the influences of the fit between the expatriate's learning style and instructor's teaching modes on training effectiveness.Design/methodology/approachSurvey methodology was adopted to obtain data from the opinions of expatriates in foreign companies within Taiwan and China. Quantitative data were used to answer the research questions. A total of 400 foreign companies, with 200 in Taiwan and 200 in China, were selected as the survey sample. Hierarchical regression analyses were adopted to test the five research questions as developed in this study.FindingsThe study results revealed that expatriates' perceived needs for training were negatively influenced by competence and adaptability to work in the overseas assignment. Expatriates' perceived needs for expatriation training were also influenced by the complexity of the task assignment, capability of host country managers, and the perceived cross‐culture differences between the home country and host country. Furthermore, the levels of fit between expatriate learning preferences and the instructor's teaching methods did moderate the relationship between the need for expatriate training and the effectiveness of such training.Research limitations/implicationsFirst, since this study adopts cross‐sectional research design and examines the opinions of expatriates at one point in time, directional relationships may not be clear. It is recommended that future research conduct longitudinal studies to confirm the findings of this study. Second, due to the constraints of time and resources, the samples of this study are limited to expatriates working for foreign firms in Taiwan and in China. The generalization of the study results should thus be interpreted with appropriate caution. It is recommended that the same questionnaire, or an abbreviated form, could be used for expatriates in other countries, such as expatriates of multinational subsidiaries with US, Japanese, and European investment origins. Additional research will further confirm the validity and generalizability of the findings.Originality/valueThe training of expatriates has been recognized as one of the key elements for the success of business globalization. However, the evaluation of the effectiveness of training and development for overseas expatriates has remained largely unclear. The results of this study enabled one to understand how relevant contingency factors influence expatriate training needs and effectiveness. These findings could provide importance references for academics and practitioners when deciding on business practices.
