The earth ecosystem is seriously damaged due to the self-interest behavior of human, which nonetheless poses a huge threat to the survival of human. The ecological environment and public health in Taiwan also face increasingly deteriorating situation, which is compounded with the problem of a dramatic increased number of families eating out with the most popular choice as lunch boxes mostly. To improve this situation, visionaries push for organic lunch boxes. However, there are still some factors lacking and some problems persisting for marketing organic lunch boxes. It is hoped that the result of this study can be beneficial to the relevant organizations as a reference for promoting organic lunch boxes. Literature review and in-depth interviews are conducted as the basis for developing questionnaire in this study. I also propose a behavior model for purchasing organic lunch boxes based on the theory of consumption values by Sheth, Newman, and Gross (1991), Theory of planned behavior by Ajzen (1991), and the EKB model by Engel, Blackwell, and Miniard (1993) This model consists of nine variables: the functional value of organic lunch box, its social value, its emotional value, its curious value, its conditional value, the subjective norms, self-efficacy, shopping environment, and the degree of involvement etc. To test this model, regression analyses are conducted using those nine variables and two behavior intention dependent variables in this study. These two behavior intention variables respectively are: the subject¡¦s behavior intention to purchase organic lunch boxes when price is not specifically mentioned (BI1) or they are suggested to assume that the price of the organic one will be close to that of a regular one (BI2). The result shows that the functional value and the degree of involvement both have significant influence on BI1 and BI2; while the conditional value, the emotional value, and self-efficacy are only have significant influence on BI2, which can explain the 22.1% variation of BI1 and the 26.2% variation of BI2 respectively. Furthermore, in order to investigate the variation of the behavior intention BI1 to purchase organic lunch boxes due to the difference of personal attributes, t test and single factor ANOVA are adopted. The result shows that marital status, age, occupation, personal monthly income, knowledge of organic product, purchasing frequency for organic ingredients, and the amount of money for purchasing organic ingredients all have significant influence on the variation of behavior intention for purchasing organic lunch boxes (BI1); while gender, educational level, self health status, and family's health status do not have significant influence on the variation of behavior intention for purchasing organic lunch boxes. We will propose application from these results and make relevant recommendations to industries and government based on this study.
