Kinmen County has developed ”Certification of Kinmen Safety Vegetables and Fruits” to raise the food safety and quality for produce, hoping to increase Kinman's willingness to buy agricultural products. This research interviewed consumers on the spot and found that 92% of them are able to recognize CAS organic label. And they value certain items a lot, such as the mark of preservation time limit, the freshness of food and if the products are contaminated by the environment and pesticide residue. Based on cluster analyzing to segment the market, the public can be separated into the cluster of high comprehensive safety perception, the cluster of consuming CAS organic label and the cluster of valuing produce-selling history. Among the three groups, the first group stands for organic agricultures in the project of enhancing produce safety and is willing to .increase the highest level of frequency for consumption. On the other hand, those in the second group are willing to pay the largest premium for organic products.
