Abstract
The present study aims to explore the impact of career development support on job adaptation and withdrawal intention, and the multilevel moderating role of host country environmental factors. Through the questionnaire survey, we collected 242 expatriates' data of 25 countries from China's multinational corporations. Based on the constructed multilevel analysis model, we find: (1) career development support has a significant impact on job adaptation and withdrawal intention of expatriates; (2) job adaptation plays a mediating role between career development support and withdrawal intention; and (3) host country environment plays the multilevel moderating role between career development support and job adaptation. Through the multilevel model of host country environment, this study explores the mechanism of how career development support affects job adaptation and withdrawal intention. The conclusions enhance the understanding of the adaptation of expatriates and have important theoretical and practical reference value to achieve successful expatriate in the context of host country environment.
