The power of nostalgic emotion: how Hong Kong traditional tong sui influences generation Z's purchase intentions

Purpose Of the studies covering culinary tourism and traditional culture, Generation Z remains an underexplored group despite being the primary consumers of future tourism. Research into young consumers’ motivations is hoped to clarify, protect, and sustain Hong Kong Tong sui among this generation. As such, this study focuses on Generation Z to understand the types of novel experiences Tong sui can create for them, and it is worth exploring in depth the diet that young people are interested in from the perspective of traditional food. Design/methodology/approach Based on Creswell’s guidelines for quantitative research, we investigated the relationships among multiple elements of Hong Kong Tong sui and Generation Z tourists. A corresponding questionnaire was designed to gather information for statistical analysis and contains five sections. The first part solicited basic respondent information. Sections 2–5 presented several key terms (nostalgic emotion, food authenticity, FCV, and purchase intention) to frame the questionnaire in terms of our hypotheses. Items were scored on 7-point Likert-type scales for ease of processing in SPSS 26.0. Findings All hypotheses were supported, with nostalgia having the most significant influence on Generation Z’s purchase intentions. Besides, young generations are willing to buy traditional food when exposed to the restaurants or enterprises have nostalgic elements and inspire nostalgia in consumer. Generation Z’s thoughts about food authenticity notably played a more significant role than FCV in terms of the nostalgia of traditional food. In addition, food authenticity and FCV were found to indirectly mediate the relationship between nostalgic emotion and purchase intention. Research limitations/implications Examining these types of campaigns geared toward Generation Z tourists to advertise traditional food has enriched this tactic’s applicability. The approach also constructs a foundation to scrutinize the appeal of traditional dishes among young consumer groups to potentially strengthen such food’s influence. Practical implications This study highlights the importance of leveraging nostalgia and understanding the emotional connection that Generation Z has with traditional cuisine. It suggests that enterprises can develop new products or revive traditional recipes that cater to the nostalgic preferences of Generation Z. Marketing innovations, such as using social media influencers, can also be employed to create awareness and generate interest in traditional food. Traditional food can contribute to tourist destinations' promotion and differentiate them from competitors, boosting the tourism and catering industries and creating employment opportunities. Social implications The promotion and preservation of traditional food can contribute to the preservation of cultural identity and heritage. By engaging local communities in culinary initiatives and fostering community pride, traditional food tourism can strengthen the connection to cultural heritage and encourage the preservation of traditional culinary practices. This engagement can lead to sustainable development by promoting local traditions and ensuring the participation of the local community in tourism activities. Originality/value This study offers novel theoretical insights into traditional food consumption and food marketing, thus narrowing gaps in research on young consumers and traditional food. Results enrich the understanding of Generation Z’s intentions to purchase traditional food by highlighting tourists’ preferences. Guidelines are also provided for the operators on creating nostalgic campaigns that appeal to young generations.
