Thereby, marking the increase of e-commerce in Thailand as the highest in ASEAN due to significant changes in consumer behaviour, according to the Electronic Transactions Development Agency (ETDA). Meanwhile, competition among e-retailers has also become more and more fierce. Therefore, this study aims to investigate the 'what' and 'how' of factors influencing the Thai customers' buying behaviour through prepurchase, purchase, and post-purchase phases. An expanded research model developed based upon the theory of planned behaviour will be employed. The research method employed a sample of 535 online consumers to test the hypotheses and adopted a structural equation to analyse the surveyed information. The findings of this study will serve as useful references for e-retailers to garner a better understanding of online customers' buying behavior through multiple-stage perspectives.vii, 50 leaves: ill.application/pdfengผลงานนี้เป็นลิขสิทธิ์ของมหาวิทยาลัยมหิดล ขอสงวนไว้สำหรับเพื่อการศึกษาเท่านั้น ต้องอ้างอิงแหล่งที่มา ห้ามดัดแปลงเนื้อหา และห้ามนำไปใช้เพื่อการค้าConsumer behavior -- ThailandMotivation research (Marketing) -- ThailandMaster ThesisMahidol University
