Base on the social exchange theory, this study examines the effects of employee perceived supervisor support on turnover intention, and exploring the moderate effects of job-loading and achievement motivation (individual-oriented achievement motivation, social-oriented achievement motivation). The military officers were selected as target sample. In the 399 effective responses, we found three results: 1. The more employees perceived supervisor support, the lower perceived turnover intention. 2. The job-loading will lessen the negative influence of employee perceived supervisor support on turnover intention. 3. The social-oriented achievement motivation will strengthen the negative influence of perceived supervisor support on turnover intention. This study discussed research findings both in terms of theoretical development and of practical management implications.
