After independent T test, Chi-test and ANOVA, we conclude as followed, First, in the aspects of the results of factors among top 5 products, only both resident area and educational background can influence on comsumption of different products. Different products can be delivered based on different area to rise up the revenue amounts. Second, of aspects of product repurchasement, gender, resident area and educational background, the three factors will influence on times of product purchasement. Third, likewise, only both resident area and educational background can influence on different channels.Relatively speaking, most of customers are introduced by broadcasting in Middle-southern of Taiwan, and the percentages of poor-educated people are higher among them. Forth, of aspects of the affective factors of customer satisfactory, only resident area resulted in diversifications in customer satisfactory. To be further analyzed, north and middle customers do not differ, but the south of customer satisfactory is significantly higher than the former.
