Tóm tắt:
Mục tiêu nghiên cứu: Nghiên cứu đánh giá tác động của truyền miệng điện tử (eWOM) đến ý định đặt vé máy bay trực tuyến (YĐĐVMBTT) tại Việt Nam, đồng thời xác định vai trò trung gian của hình ảnh thương hiệu (HATH) và vai trò điều tiết của động cơ mua hàng (ĐCMH) cùng rủi ro cảm nhận (RRCN).
Thiết kế nghiên cứu/phương pháp/tiếp cận: Phương pháp định lượng được áp dụng với dữ liệu khảo sát từ 770 khách hàng từng đặt vé máy bay trực tuyến trong 12 tháng gần nhất. Mô hình phương trình cấu trúc bình phương bé nhất (PLS-SEM) được dùng để kiểm định các mối quan hệ trực tiếp, gián tiếp và tương tác giữa các biến.
Kết quả nghiên cứu chính: Kết quả cho thấy eWOM ảnh hưởng cùng chiều đến HATH và YĐĐVMBTT. HATH là biến trung gian quan trọng, chuyển hóa tác động của eWOM thành thái độ và hành vi mua tích cực. ĐCMH làm tăng cường mối quan hệ giữa eWOM, HATH và ý định đặt vé. Trong khi đó, rủi ro cảm nhận điều tiết mối quan hệ giữa eWOM và ý định đặt vé, thể hiện xu hướng khách hàng dựa vào eWOM nhiều hơn khi mức độ bất định cao.
Giá trị đóng góp mới: Nghiên cứu mở rộng lý thuyết hành vi tiêu dùng trực tuyến bằng cách tích hợp đồng thời cơ chế trung gian và điều tiết trong một mô hình duy nhất, đồng thời mang lại hàm ý cho các hãng hàng không trong việc tối ưu hóa eWOM, cá nhân hóa thông điệp và giảm thiểu rủi ro cảm nhận nhằm gia tăng tỷ lệ đặt vé trực tuyến.

Abstract:
Purpose: This study examines the impact of electronic word of mouth (eWOM) on online flight ticket purchase intention (OFTPI) among Vietnamese customers, while identifying the mediating role of brand image and the moderating roles of purchase motivation and perceived risk.
Design/methodology/approach: A quantitative approach was employed using survey data from 770 respondents who had booked flight tickets online within the past 12 months. Partial Least Squares Structural Equation Modeling (PLS-SEM) was applied to test the direct, indirect, and interactional relationships among the variables.
Findings: Results indicate that eWOM positively and significantly influences both brand image and OFTPI. Brand image acts as a key mediator, translating eWOM effects into favorable attitudes and purchasing behaviors. Purchase motivation strengthens the relationships between eWOM, brand image, and purchase intention, while perceived risk moderates the link between eWOM and purchase intention, showing that customers rely more on eWOM when uncertainty is high.
Originality/value: This study extends online consumer behavior theory by integrating both mediation and moderation mechanisms within a single structural model. It also provides practical implications for airlines to optimize eWOM strategies, personalize marketing messages, and reduce perceived risk to enhance online booking rates.
