Factors influencing and criteria of supplier selection for EEC company Thailand

Abstract

This study examines the factors influencing supplier selection decisions in the Eastern Economic Corridor (EEC) through a review of relevant literature and prior research related to the EEC, as well as procurement concepts and supplier selection theories. The conceptual framework incorporates price, service quality, and reliability as independent variables, with supplier selection as the dependent variable. Data were collected using a five-point Likert- scale questionnaire. Multiple regression analysis was employed to analyze the factors affecting the selection of high-quality suppliers that offer reasonable pricing, reliability, and the ability to meet business requirements without causing operational disruptions. The findings highlight that selecting efficient and effective suppliers contributes to improved business management and supports the development of an efficient and sustainable supply chain.
