In summary, male restaurateurs were higher in the vision directivity, desire to learn, accomplishment, challenge and pro-activity than their female counterparts, with a significant difference of p<0.05. According to their ages, the surveyees showed significant differences in the vision directivity (p<0.05), desire to learn (p<0.01), challenge (p<0.01) and pro-activity (p<0.01). In addition, also the survey revealed that the qualities of a restaurateur had a significant influence on financial performance, a sense of satisfaction and business results (p<0.001). The questionnaire resulted in the following: first, the vision directivity (p<0.05) and the challenge (p<0.05) affected the financial performance; second, the challenge had influence on the sense of satisfaction; and last, the vision directivity (p<0.05) and the challenge (p<0.05) had an effect on the business results.
