Studies of Selection Attributes for Lunch Boxes (Dosirak) Using Conjoint Analysis among Single Men

Abstract

This study analyzed the comparative importance of the selection attributes of a lunch box (dosirak) in single men and suggests a solution for the ideal type of lunch box that would appeal to single men using conjoint analysis techniques. A total of 252 questionnaires were distributed to single men who had previously purchased a lunch box in convenience stores or franchise dosirak stores. The conjoint design was applied to evaluate a hypothetical lunch box for single men. As a result, the order of importance of the attributes of the lunch box was found to be the price (41.66%), menu composition (24.62%), delivery status (17.45%), and place of purchase (16.27%). The ideal combination of the selection attributes of lunch box was a purchase in a franchise dosirak store, having a delivery service, a type 3 menu (Rice･Kimchi＋fried pork cutlet, chicken, fish cutlet), and a low price of 3,500 won. The most preferred lunch box showed an incremental 57.6% potential market share using choice simulation compared to the lunch box being currently sold. Using the utility of attributes, the lunch box market for single men was classified into two segments. As a result of market segmentation, single men of cluster 1 preferred a lunch box with the menu type 2 and a price of 8,500 won while single men of cluster 2 preferred a lunch box with the menu type 3 and a price of 3,500 won. These results will help establish a database that contributes to the development of differentiated products and building marketing strategies that can satisfy the needs of single men.
