Social satisfaction has become an important factor to help an enterprise succeed. A new way to measure social satisfaction called social license has been proposed recently. Based on the concept of CSR (Cooperation Social Responsibility), SLO (Social License to Operate) was put forward in the 1990s. However, the concept of SLO was just used in a limited range of industries such as the mining industry. Yet this concept has not been well developed or utilized in cases like site selecting analysis and satisfaction survey. In this study, SLO will be explained and tested in the food industry and a specific survey will be done to analyze the feasibility of this concept as well as crucial factors that influence the assess of social satisfaction. There is ample evidence suggesting that the SLO, as a measurement of social satisfaction, is quite supportive in decision making for food industry companies.
