nostalgia scales); 2) diversity of analytical methods
(e.g., SEM, multilevel modeling); 3) expansion of
research settings—from offline to online
environments. However, there are clear limitations:
reliance on self-reports, lack of longitudinal tracking,
and limited use of neuroscience methods. Ongoing
debates include how to classify emotions (valence vs.
arousal), whether cognitive appraisal precedes
emotional response, and cultural differences in
emotional expression.
While the fundamental framework for studying
emotional impact on loyalty is established, future
research should enhance mechanism precision, adopt
dynamic methods, and integrate interdisciplinary
theories. Especially in the digital age, the traditional
emotion–loyalty model may be evolving and deserves
further academic attention. In summary, consumer
emotion and brand loyalty research has formed a solid
theoretical system and confirmed the importance of
emotion in brand marketing. However, there is room
for improvement in theoretical depth and
methodological diversity. Future research should
integrate interdisciplinary perspectives and adopt
dynamic, multi-method approaches to reveal the
underlying mechanisms more comprehensively.

Consumer Emotion and Purchase
Intention
2.2.1 Summaries of Current Studies
The interaction between consumer emotions and
brand loyalty is a key topic in brand marketing
research. Existing studies explore the internal
mechanisms between these two factors from different
dimensions, but there are limitations in theoretical
frameworks and methodologies. This paper compares
and analyzes the impact paths and mechanisms of
consumer emotions on brand loyalty based on three
representative studies. The research finds that high-
quality products combined with positive emotional
extension significantly improve consumer attitudes
and brand loyalty. Conversely, negative emotions or
excessively fanatic hostile brand loyalty can trigger
negative attitude polarization among other users. In
terms of research methods, current studies often use
quantitative analysis (e.g., SPSS statistics, regression
analysis) and theoretical model construction (e.g.,
trait transfer, attitude polarization theory). However,
they suffer from a single theoretical perspective and
limited empirical samples. Future research should
integrate interdisciplinary theories and adopt mixed
research methods to further explore the dynamic
relationship between consumer emotions and brand
loyalty, providing more comprehensive theoretical
support for brand marketing practices.
2.2.2 Current Research Status
Existing studies show that consumer emotions have a
multidimensional effect on brand loyalty. Shen (2012)
ocused on time-honored brands and explored how
nostalgic emotions (e.g., emotional nostalgia,
preference nostalgia) influence brand loyalty through
the mediating role of time-honored brand perceived
value. It was found that consumer involvement plays
a moderating role. However, family nostalgia and
interpersonal nostalgia had a weaker impact on brand
loyalty due to their lack of direct connection with
time-honored products. Similarly, the study on virtual
influencers found that virtual influencer endorsements
could enhance brand loyalty by increasing consumers’
“emotional engagement,” with positive emotions (e.g.,
affection, trust) serving as key mediators . Moreover,
research on “hostile brand loyalty” revealed the
negative impact of consumer emotions . In the study
Luo ’s study, it was found that fanatic fan emotions
could lead other consumers (e.g., utilitarian users) to
develop negative emotions towards the brand,
resulting in “attitude polarization” and “trait transfer”
as a crucial mediator in this process. Changju tested
the moderate mediation hypothesis using PROCESS
macro and found that consumer resistance indirectly
influenced brand strength by reducing national affinity.
Current research mainly employs quantitative
analysis methods, such as surveys, regression analysis,
and structural equation modeling (SEM). For example,
Li ’s study used SPSS for factor analysis, correlation
analysis, and regression analysis, confirming a
positive relationship between nostalgic emotions and
brand loyalty. Shen’s study empirically explored how
virtual influencer endorsements affect consumer
brand attitudes. The “Hostile Brand Loyalty Study”
combined “trait transfer theory” and “attitude
polarization theory,” using experimental or survey
methods to analyze the negative effects of fan
behavior on brand image. Although these studies are
methodologically mature, they typically rely on cross-
sectional data, which makes it difficult to dynamically
track the long-term evolution of consumer emotions
and brand loyalty.
The analysis results of each study also show
distinct characteristics. In “The Influence of
Consumer Nostalgia on Time-Honored Brand
Loyalty,” empirical findings show that personal
nostalgia, family nostalgia, product nostalgia, craft
nostalgia, and advertising nostalgia are all positively
