Corporate profit derives from new and returning customers. As a result, corporations should not only aggressively acquire new customers, but also retain existing customers and establish long-term relationships with them. Therefore, corporations who can successfully exercise customer relationship strategies can not only develop long-term, stable relationship with customers, but also build significant competitive advantages. Through investigating the relationships among product core benefit, corporate image, customer value, and customer commitment, this research hopes to understand the concerns when customers extend contracts for future reference of sales and marketing in the insurance industry. The targets of this research are policy holders of one of the national insurance companies. This research adopts a convenience sampling method. 300 questionnaires were issued. 237 of them were retrieved, out of which 17 are invalid and 220 are valid. SPSS10 data analysis method is used to perform descriptive statistics analysis, reliability analysis, correlation analysis, regression analysis, and variance analysis. This research introduced Cronbach’sαcoefficient to conduct reliability analysis. Reliabilities of the four variables and the reliability of the entire questionnaire are higher than 0.7. Therefore, the result is highly reliable. It appears that the questionnaire is internally consistent and is suitable for performing positive analysis. The results of the research were: (1)Product core benefit has obvious positive effect on customer commitment. It appears that if corporate can put their effort on increase product core benefit awareness, customer commitment will increase; (2)Corporate image has an obvious positive effect on customer commitment. It appears that when customers perform purchasing behavior, corporate image also has a significant inf1uence on customers’ choices other than product core benefit; (3)Customer value has an obvious positive effect on customer commitment. It appears that the creation of customer value can effectively increase customer commitment. That is to say, the higher the customer value; the more the corporate identity and the more customers devote to corporations. The relationship between corporations and customers will be more stable; (4)Via Customer value, product core benefit and corporate image has obvious effect on customer commitment. It appears that customer value has an intermediary effect between customer commitment and both product core benefit and corporate image.
