This study examined the structural relationship among perceived quality, perceived value, environmental commitment, purchasing attitude, and purchasing intention, and also the moderating roles of environmental concern of organic food consumers. A total of 420 questionnaires were distributed to female consumers in Seoul and Gyeonggi area, of which 380 were deemed usable for the statistical analysis. To test a total of six research hypotheses, a structural equation modeling approach was utilized and a multi- group analysis was performed to test for the moderating effects of environmental concern. Based on data analysis, the results indicate that perceived value significantly affects environmental commitment which leads purchasing attitude and purchasing intentions while perceived quality indicated no significant effect on environmental commitment. In addition, the moderating effect of environmental concern between environmental commitment and purchasing attitude of organic food was significantly apparent. The Study`s findings provide some meaningful theoretical and managerial implications for organic food industry. Limitations and future research directions were also discussed.
