PurposeThe purpose of this paper is to investigate gender differences in organizational commitment (OC) and the relationship between OC and rewards among employees who work for Japanese manufacturing companies within China.Design/methodology/approachThis study utilized hierarchical regression analysis to examine survey data obtained from 27,854 employees who worked for 64 Japanese manufacturing companies within China.FindingsThe results reveal that autonomy and role clarity had a stronger influence, and co-worker support had a weaker influence, on OC for male employees than for female employees. These differences may be because more male employees than female employees prefer working with higher autonomy and well-defined roles than with co-worker support. After all, male employees, who place a great emphasis on independence, competition, decision-making and challenges, rely on intrinsic rewards more than social rewards.Research limitations/implicationsThis study used data collected from Japanese manufacturing companies to understand the differences between OC and rewards in local male and female Chinese employees. We recommend that future research uses other national affiliates to clarify the characteristics of male and female Chinese workers more objectively and to test the validity of this research.Practical implicationsThe results of this study support revising human resource management practices within multinational enterprises to enable female and male host-country workers to contribute to their companies on a long-term basis by taking into account the differences between the cultures of the home and host countries.Originality/valueAlthough previous research has elucidated the OC–rewards relationship in particular countries, it has not met the requirements of foreign managers from different corporate cultures who face differences in the OC–rewards relationship between their male and female employees. In this sense, this research is the first attempt to tackle this theme and contribute to the literature.
