This study evaluated the consumers’ demands and points of improvement for restaurant meal replacement through importance–performance analysis by the restaurant meal replacement segment market using food involvement. The results were as follows. First, after segmenting the restaurant meal replacement market using food involvement, it was classified into three markets (multiple involvements, exploration-oriented, and product quality-oriented). Second, an analysis of the importance of restaurant meal replacement selection attributes revealed taste, sanitation, quality, freshness, price, saving time, texture, ingredients, preparation process, and quantity to be highly important. An analysis of the differences according to the market type revealed the multiple involvement type to be more important than other groups, considering the restaurant meal replacement selection attribute element. Third, an analysis of the importance-performance analysis of restaurant meal replacement selection attributes revealed that quantity and price as the selection attributes that needed to be improved first in all three markets. In addition, in the multiple involvement type, food additives appeared as a selection attribute requiring priority improvement, revealing the characteristics of a market that cares about diet and health.

The purpose of this study was to understand the effect of loyalty program in family and fastfood restaurant on relationship quality (trust, commitment) and revisit intention. Based on total 394 samples obtained from empirical research, this study reviewed the reliability and fitness of a research model using the Amos program. The hypothesized relationships in the model were simultaneously tested using a structural equation model (SEM). The proposed model provided an adequate fit to the data, χ2 102.338 (df 48), GFI .959, RMR .049, NFI .970, CFI .984 SEM resulted that loyalty progam (β= .429, t=7.880, p〈 .001) showed a positive significant effect on trust, and that loyalty program (β= .455, t=9.532, p〈 .001) had a positive significant effect on commitment. Also, both trust (β= .450, t=6.595, p〈 .001) and commitment (β= .474, t=5.117, p〈 .001) had a positive significant effect on revisit intention. In addition, there were moderating effects related to restaurant type (family and fastfood restaurant) in terms of causal relationships between loyalty program, relationship quality and revisit intention. Limitations and future research directions are also discussed.
