Tóm tắt:
Mục tiêu nghiên cứu: Nghiên cứu nhằm khám phá các yếu tố có ảnh hưởng đến ý định mua sản phẩm xanh (YĐMSPX) trong bối cảnh tiếp thị qua video review của những nhân vật có ảnh hưởng (Key Opinion Leaders – KOL). Đồng thời, nghiên cứu đánh giá vai trò trung gian của niềm tin xanh (NTX), cảm giác cộng đồng (CGCĐ) và vai trò điều tiết của hoài nghi xanh (HNX), dựa trên khung lý thuyết Đáp ứng kích thích (SOR).
Thiết kế nghiên cứu/phương pháp/tiếp cận: Nghiên cứu sử dụng phương pháp định lượng với 300 mẫu khảo sát hợp lệ từ người tiêu dùng Việt Nam thuộc thế hệ trẻ có kinh nghiệm xem video review từ KOL trên mạng xã hội. Dữ liệu được phân tích bằng mô hình cấu trúc PLS-SEM thông qua phần mềm SmartPLS 4.0 để kiểm định mô hình lý thuyết và các giả thuyết nghiên cứu.
Kết quả nghiên cứu chính: Chất lượng video review và sự hiện diện xã hội (SHDXH) của KOL có tác động cùng chiều đến NTX và CGCĐ, hai yếu tố này đóng vai trò trung gian quan trọng trong việc thúc đẩy YĐMSPX của người tiêu dùng. Đặc biệt, biến HNX thể hiện vai trò điều tiết đáng chú ý khi làm gia tăng ảnh hưởng của CGCĐ đến ý định mua, trong khi không tạo ra tác động đáng kể đến mối quan hệ giữa NTX và ý định mua.
Giá trị đóng góp mới: Nghiên cứu này làm rõ vai trò kết nối giữa yếu tố nhận thức, cảm xúc và HNX trong khuôn khổ lý thuyết SOR. Cách tiếp cận này giúp lý giải sâu hơn về động lực hình thành ý định tiêu dùng xanh trong bối cảnh truyền thông số. Kết quả nghiên cứu mang lại hàm ý thực tiễn cho doanh nghiệp và KOL trong việc xây dựng chiến lược tiếp thị phù hợp với xu hướng tiêu dùng bền vững.

Abstract:
Purpose: This study aims to explore the factors influencing green purchase intention in the context of marketing through video reviews by Key Opinion Leaders (KOLs), while assessing the mediating role of green trust and sense of community, and the moderating role of green skepticism, based on the SOR theoretical framework.
Design/methodology/approach: The study employs a quantitative method with 300 valid survey samples from young Vietnamese consumers with experience watching video reviews from KOLs on social media. Data were analyzed using the PLS-SEM structural model via SmartPLS 4.0 software to test the theoretical model and research hypotheses.
Findings: KOL video review quality and social presence have a positive impact on green trust and sense of community, these two factors play an important mediating role in driving consumers' green purchase intention. Notably, the green skepticism variable demonstrates a significant moderating role by increasing the influence of sense of community on purchase intention, while not creating a significant impact on the relationship between green trust and consumer behavior.
Originality/value: This study clarifies the connecting role between cognitive factors, emotions, and green skepticism within the SOR theoretical framework. This approach explains more deeply the dynamics forming green consumption intention in the digital media context. The research results offer practical implications for businesses and KOLs in building marketing strategies suitable for sustainable consumer behavior.
