英文文献摘要：
This study analyses the economic value of various components of the Certified South Carolina Grown Campaign from the perspective of participating restaurants. A stated-preference choice experiment was conducted as part of the restaurant survey to estimate the willingness to pay (WTP) for each campaign component using a mixed logit model. Individual level WTP was calculated in order to explore the relationship between WTP and characteristics of restaurants. Results indicate that three existing components--Labeling, Multimedia Advertising, and "Fresh on the Menu" have significant positive economic value.
