Factors affecting the selection of refrigerated container services of durian export middlemen in Chumphon Province

Abstract

This research examines factors influencing the selection of refrigerated container service providers (7R) among durian middlemen exporters in Chumphon Province, Thailand. The study sample consisted of 199 durian trading houses in Chumphon Province, selected through stratified random sampling. Data were collected using a questionnaire specifically designed for field research. The statistical analysis employed descriptive statistics, including frequency, percentage, mean, and standard deviation, and inferential statistics using multiple regression analysis to examine the relationships between the studied factors and the selection of refrigerated container services. The findings revealed that the most influential factors in selecting refrigerated container service providers (7R) were right customer (B = 0.351), which had the highest impact, followed by right product (B = 0.284) and right quantity (B = 0.212). These three factors collectively explained 57.3% (R² = 0.573) of the variance in refrigerated container service selection among durian middlemen exporters in Chumphon Province, indicating significant relationships between these factors and service provider selection decisions.
