“…The majority of scholars have expanded the use of perceived value theory. For example, Choi et al [38] divided the perceived value of souvenirs into perceived emotional value, perceived social value, perceived functional value (quality), and perceived functional value (price/value for money); Deng et al [39] divided perceived value into perceived functional value, perceived memorial value, perceived emotional value, perceived social value, and perceived conditional value; Lin and Wang [40] argued that perceived value is reflected in the dimensions of reputation, quality, monetary value, and emotional response; and Fu et al [22] argued that the perceived value of tourism souvenirs is reflected in memorial value, spiritual value, functional value, emotional value, and social value. Although the existing studies have not yet formed a unified system on the specific dimensions and layers of tourist perceived value, several dimensions have been repeatedly mentioned in the above dimensional divisions, such as perceived functional value and memorial value from the perspective of products, perceived emotional value, and perceived social value from the perspective of tourists.…”
