This research explored the relationship among human resource practitioner professional ability, achievement motivation and the degree of human resource management system construction. The research focus was the human resource management practitioners in enterprises and data were collected through convenience sampling. Three hundred questionnaires were sent out, 223 valid questionnaires were returned (74.33%). The results show that there is a significant influence between the: (1) professional ability of human resource management practitioners and the degree of human resource management system construction and (2) achievement motivation of human resource management practitioners and human resource management system construction and also that (3) achievement motivation has a moderating effect between professional ability and the degree of human resource management system construction. Empirical analysis showed that achievement motivation does exist a partial mediating effect between professional ability and human resource system construction. It means that the level of achievement motivation will affect system construction. Therefore, how to increase the achievement motivation degree will be the critical point.
