선택 기반 컨조인트 분석을 통한 감귤 선호도 조사

Abstract

Conjoint analysis is a method that predicts the consumer choice by estimating the utility of product's attributes. This study aims to investigate how citrus products can be optimized based on consumer preferences through a choice-based conjoint analysis method. Citrus is one of Jeju's main fruit and play an important part in the Jeju agricultural market. This study seeks to identify the atrribute of citrus that influence consumer choice. In this study, we conduct a choice-based conjoint analysis on four attributes of citrus, including weight, size, price, and packaging. The analysis model is the part-worth function model and the vector model. The part-worth function model estimated the utility of attribute level and the relative importance of the attributes. The vector model estimated the willingness-to-pay price, and then estimated latent class analysis. As a result, weight, size, and price had a great influence on consumer choice among the four attributes, while packaging had a relatively small influence. This study provides valuable insight to explores the optimal combination of citrus attributes preferred by consumers. The optimal combination increase the competitiveness of citrus in the market. And it provide guide to build effective product development strategies and market segmentation strategies for Jeju farmers and agricultural entrepreneurs.
