TikTok Shop, social commerce INTRODUCTION The development of digital technology has significantly transformed the landscape of commerce, particularly through the emergence of social commerce, which integrates social media activities with direct buying and selling transactions. One of the social commerce platforms that has experienced rapid growth is TikTok Shop. This platform combines video-based entertainment content with e-commerce features, thereby creating an interactive and community-driven shopping experience. This phenomenon has positioned TikTok Shop as a strategic channel for businesses to reach consumers in a more emotional and persuasive manner compared to conventional e-commerce platforms (Han et al. , 2. Consumer purchase intention is a key variable in determining the success of marketing in digital platforms. Purchase intention is defined as the psychological tendency of consumers to buy a product after going through a process of information evaluation, value perception, and prior experience (Dodds et al. , 1. In the context of social commerce, purchase intention is influenced not only by rational factors such as price, but also by emotional, visual, and social aspects formed through digital interactions (Hajli, 2. One of the main factors influencing consumer purchase intention is product quality. Product quality reflects a productAos ability to meet or exceed consumer expectations in terms of functionality, durability, design, and reliability (Garvin, 1. In a digital environment such as TikTok Shop, product quality is assessed not only through direct usage experience but also through visual representation, customer reviews, and product demonstrations via video content (Kim & Lennon, 2. Previous studies have shown that perceived product quality has a positive and significant effect on consumer purchase intention in both e-commerce and social commerce platforms (Tsiotsou, 2006. Park & Kim, 2. In addition to product quality, promotional activities also play an important role in shaping consumer purchase intention on digital platforms. Promotional activities include various marketing communication efforts such as discounts, flash sales, live streaming, influencer endorsements, and interactive promotional content designed to attract attention and encourage purchasing decisions (Kotler & Keller, 2. TikTok Shop, in particular, leverages live commerce and influencer marketing, which have been proven to significantly enhance consumer trust and engagement (Zhang et al. , 2. Effective promotion not only serves as a means of delivering information but also acts as a psychological stimulus that shapes perceived value and purchase urgency. Studies in digital marketing indicate that social media-based promotions have a direct influence on purchase intention through increased brand awareness, perceived value, and electronic word-of-mouth (Cheung et al. , 2. In TikTok Shop, the combination of visual promotion, persuasive narratives, and real-time interaction creates an environment conducive to both impulsive buying and planned purchases (Wongkitrungrueng & Assarut, 2. Although numerous studies on purchase intention in e-commerce have been conducted, empirical research specifically examining the influence of product quality and promotional activities on consumer purchase intention in TikTok Shop remains relatively limited, particularly in the Indonesian market context. In fact. TikTok Shop differs from conventional marketplaces as it emphasizes short video content, social interaction, and user preference-based algorithms. These differences have the potential to modify the relationship between marketing variables and consumer behavior (Li et al. , 2. Consequently, this inquiry is essential to address the prevailing research void by empirically investigating how product quality and promotional endeavors dictate consumer purchase intention within the TikTok Shop environment. The resulting insights aim to offer substantial theoretical advancements to the discourse on digital marketing and social Furthermore, this study provides actionable implications for commercial entities, assisting them in formulating sophisticated marketing blueprints that are deeply aligned with evolving consumer behavioral patterns. With increasing competition among sellers on TikTok Shop, a comprehensive understanding of the factors influencing consumer purchase intention becomes crucial. This study is expected to serve as a basis for strategic decision-making in improving product quality and designing promotional activities that are relevant, credible, and aligned with the needs of modern consumers. Data on TikTok Shop users recorded in February 2025 indicate that the platform has a large and globally distributed user base, with the United States and Indonesia being the two countries with the highest number of users. This finding highlights the importance of TikTok Shop as a social commerce channel that significantly influences digital consumer behavior. The objective of this study is to analyze the influence of product quality and promotional activities on consumer purchase intention on TikTok Shop. The benefits of this study are expected to contribute theoretically to the development of digital marketing and social commerce literature, as well as practically to assist businesses in designing more effective marketing strategies based on digital consumer behavior. The results of this study are also expected to serve as a basis for strategic decision-making in improving product quality and designing promotional activities that are relevant, credible, and oriented toward the needs of modern consumers. RESEARCH METHOD Utilizing a quantitative framework underpinned by a causal research architecture, this inquiry employs a survey methodology to scrutinize the interplay between product quality, promotional initiatives, and consumer purchase intention on TikTok Shop. This methodological choice ensures an objective and methodical validation of variable correlations through numerical evidence (Hair et al. , 2021. Han et al. , 2. The target population encompasses TikTok Shop users with prior purchasing experience, utilizing a purposive sampling strategy to select active participants who have executed at least one transaction. Given the indeterminate population size, a sample of 97 respondents was established via the Lemeshow formula (Hair et al. , 2021. Taherdoost, 2020. Sarstedt et al. , 2.

This stability is validated by the scores of CronbachAos alpha, composite reliability, and Average Variance Extracted, all of which align with established academic benchmarks. Regarding the Promotional Activities variable, the recorded coefficients signify that its indicators possess superior internal consistency. Similarly, the metrics for Product Quality attest that the measurement instrument is dependable and maintains high precision in evaluating the construct. For Purchase Intention, the data reflects a remarkably high level of reliability across its specific indicators. All research dimensions satisfy the necessary reliability thresholds, with internal consistency and composite reliability figures consistently surpassing the point seven zero mark and variance extraction values exceeding point five zero. Consequently, the research instrument is deemed sufficiently robust and academically sound for the subsequent phase of structural model analysis. AU Inner Model Testing This assessment is executed by interpreting the path coefficients and the coefficient of determination, alongside verifying the statistical weight of these inter-construct associations. Such validation is derived from the critical values and probability figures generated through the iterative bootstrapping process (Hair et al. , 2021. Sofyani, 2. AU R-Square Test Table 6.

Such validation is derived from the critical values and probability figures generated through the iterative bootstrapping process. AU F-Square Test Table 7. F-Square Test Results F-square Promotional Activities (X. -> Purchase Intention (Y) Product Quality (X. -> Purchase Intention (Y) Source: Processed data, 2026 As illustrated in Table 7, the effect size evaluation demonstrates that Product Quality (X. yields a coefficient of 0. 551 in relation to Purchase Intention (Y). This magnitude signifies that product excellence exerts a profound influence in elucidating the variances within consumer buying inclinations. Concurrently. Promotional Activities (X. recorded a value of 0. 342, situating it within the substantial effect bracket. These metrics suggest that while marketing initiatives provide a significant impetus for consumer interest, their impact is secondary to the primary role of product standards. Ultimately, the findings corroborate that both exogenous factors offer meaningful explanatory power within the model, with product quality emerging as the paramount determinant of consumer decision-making within the TikTok Shop landscape. AU Model Fit Test Table 8. Model Fit Test Results SRMR Saturated model Estimated model Source: Processed data, 2026 According to the data in Table 8, the Standardized Root Mean Square Residual (SRMR) for both the saturated and estimated models was recorded at 0. As this figure remains below the conventional threshold of 0. 10, the research framework demonstrates an acceptable goodness-of-fit. The equivalence between the saturated and estimated values signifies that the structural architecture accurately mirrors the empirical evidence, with no substantial discrepancy between the theoretical assumptions and the observed results. Consequently, the PLS-SEM model is deemed statistically robust and fit for evaluating the intricate relationships between the latent dimensions. AU Partial Testing and Hypothesis Testing Figure 3. Results of Partial and Hypothesis Testing The provided illustration delineates the structural framework within the Partial Least SquaresAeStructural Equation Modeling (PLS-SEM) analysis, employed to scrutinize the causal linkages between the latent dimensions of this inquiry. This model maps the trajectory and magnitude of the impact exerted by the exogenous factors Product Quality (X. and Promotional Activities (X. upon the endogenous outcome of Consumer Purchase Intention (Y) (Hair et al. , 2. Each latent construct is operationalized through a series of manifest indicators, while the numerical values assigned to the paths represent the coefficients utilized for partial assessment of the research hypotheses. Furthermore, the R-square metric within the Purchase Intention construct quantifies the collective explanatory power of the independent variables in accounting for variance in the dependent variable (Hair et al. , 2021. Sofyani, 2. ascertain the statistical weight of these inter-variable associations, a bootstrapping procedure is executed, providing the empirical foundation necessary to validate or reject the proposed theoretical propositions (Hair et al. , 2.

Furthermore, the analysis validates a simultaneous effect (H. , illustrating that the synergy between superior product standards and strategic digital promotions collectively intensifies the likelihood of These findings suggest that within the TikTok Shop ecosystem, purchase intention is significantly heightened when businesses harmonize high-caliber offerings with compelling, interactive promotional tactics, as both dimensions independently and jointly surpass established statistical thresholds for significance. AU The Effect of Product Quality on Consumer Purchase Intention Empirical evidence suggests that product excellence exerts a substantial and statistically significant influence on buying inclinations within the TikTok Shop ecosystem. This correlation implies that as the perceived caliber of an offering improves, the probability of transaction completion escalates accordingly. Within the social commerce landscape, the conceptualization of quality transcends mere physical attributes. it fundamentally encompasses the congruence between the digital representation of the item and the tangible post-purchase experience of the end-user (Dhingra et al. , 2. Previous studies emphasize that perceived product quality is shaped by visual content, product descriptions, user reviews, and seller credibility on digital platforms (Nadeem et al. On TikTok Shop, short video features and live streaming enable consumers to evaluate products more realistically without physical interaction, thereby strengthening quality perceptions and reducing purchase risk (Chan & Asni, 2. This finding is consistent with studies by Ong et al. and Rizomyliotis et al. , which state that high perceived product quality significantly increases purchase intention in social commerce. Additionally. Han et al. highlight that product quality serves as a fundamental basis for building consumer trust, which ultimately drives purchase Therefore, product quality is a strategic factor in determining sales success on TikTok Shop. AU The Effect of Promotional Activities on Consumer Purchase Intention The results also indicate that promotional activities have a positive and significant effect on consumer purchase intention on TikTok Shop. This finding confirms that effective digital promotions can increase consumer interest, engagement, and willingness to purchase. In social commerce, promotions are not only informative but also interactive and emotional (Dabbous et al. , 2020. TikTok Shop utilizes various forms of digital promotion such as short videos, live shopping, limited-time discounts, and influencer collaborations. Research shows that visual content-based promotions and real-time interaction create a more persuasive shopping experience and enhance purchase intention (Wongkitrungrueng & Assarut, 2020. Chan & Asni, 2023. Furthermore, influencer marketing has been proven to increase promotional credibility and strengthen consumer trust, particularly among Generation Z (To, 2. This finding is consistent with studies by Dabbous et al. and Sohn and Kim . , which state that digital promotional activities directly influence purchase intention through increased perceived value and electronic word-of-mouth . -WOM). Studies in Indonesia also show that TikTok Shop promotions such as discounts and live streaming significantly affect consumer purchase intention (Ong et al. , 2024. Nurshahira, 2. The Effect of Product Quality and Promotional Activities on Consumer Purchase Intention The results show that product quality and promotional activities simultaneously have a positive and significant effect on consumer purchase intention on TikTok Shop. This finding indicates that both variables complement each other in shaping perceived value and purchase Product quality provides a rational basis for evaluating product benefits and reliability, while promotional activities act as emotional stimuli that increase interest and purchase urgency (Gorji & Siami, 2. In the context of social commerce, the integration of visually presented product quality and interactive promotions creates a more convincing and persuasive shopping experience (Rizomyliotis et al. , 2. Studies by Han et al. and Ong et al. also demonstrate that the combination of product quality and digital promotion has a stronger influence on purchase intention than each variable individually. Therefore. TikTok Shop marketing strategies should optimize both aspects simultaneously. CONCLUSION AUBased on the results and discussion, it can be concluded that product quality and promotional activities play a crucial role in increasing consumer purchase intention on the TikTok Shop platform. Product quality has a positive and significant effect on purchase intention, indicating that better perceived product quality increases consumersAo likelihood of making a purchase. This finding highlights that in social commerce, consistency between digital information and actual product experience is a key factor in building consumer trust and purchase intention. Additionally, promotional activities also have a positive and significant effect on purchase intention. Interactive, visual, and influencer-supported digital promotions enhance engagement and encourage purchasing decisions. Simultaneously, product quality and promotional activities complement each other in influencing purchase The combination of high-quality products and effective promotions creates a positive shopping experience and enhances seller competitiveness on TikTok Shop. Thus, this study contributes theoretically to the development of digital marketing and social commerce literature, as well as practically by providing insights for businesses in designing marketing strategies focused on product quality and promotional effectiveness.
