Abstract: In the automobile distribution centers, salespeople are the main representatives of the enterprises, who are responsible for communication, sales promotion and helping customers to make purchase decisions, thus creating revenues for the enterprises. Therefore, how to evaluate the sales performance of the automobile salespeople is always an essential theme for management researchers. This study aims to understand the impacts of salesmen’s personality traits and the learning effects on the results of sales performance. The path analysis of the proposed model shows that personality traits, such as “Conscientiousness”, “Extroversion”, “Openness” and “Neuroticism” , will influence sales performance. However, the mediated effects of learning do not have a significant influence on different personality traits. By MANOVA’s Post hoc analysis, for male salespeople, learning is a more significant factor than it is for females’. As to financial performance, a significant difference can be found in terms of both years of service and marital status. Further verification shows that the difference comes from years of service, but not from marital status. Therefore, reducing staff turnover rate will result in a better financial performance for the enterprises.
