A key driver of retention is the quality of customer service interactions across different communication modes. Prior research largely focuses on perceptual or experiential outcomes of communication mode differences, but does not examine how the four dimensions of Media Richness Theory (MRT) manifest as objective behavioral features in real-world customer service interactions. It also remains unclear whether these dimensions exert uniform or differential effects on customer renewal, and whether a richer communication medium uniformly benefits customer retention. This study addresses two research questions. RQ1 examines how voice calls and text chats differ across the four dimensions of media richness (i.e., immediate feedback, natural language use, multiple cues, and personal focus) in actual customer service interactions; RQ2 examines how these differences influence customer churn. Using large-scale interaction data from a Chinese online education platform, we develop an objective framework that operationalizes each dimension using behavioral indicators from interaction logs. Results show that voice calls are richer than text chats across all MRT dimensions. However, their effects on churn differ by dimension: feedback immediacy and personal focus reduce churn, natural language use shows no significant effect, and multiple cues exhibit a more nuanced pattern. These findings extend MRT to customer relationship management and offer actionable insights for designing more effective service interactions.</div></div>","PeriodicalId":50541,"journal":{"name":"Electronic Commerce Research and Applications","volume":"79 ","pages":"Article 101643"},"PeriodicalIF":6.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149140660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results reveal that retailers’ optimal information sharing strategy depends on freshness elasticity. Interestingly, retailers never share demand information directly with the supplier, focusing all their direct vertical information sharing exclusively on the 3PL, while the supplier and the 3PL endogenously transmit the information they receive to each other. Specifically, when freshness elasticity is low, retailers do not share information horizontally, and neither retailer shares demand information with the 3PL. When freshness elasticity is intermediate, retailers share no information horizontally, but both retailers share demand information with the 3PL. When freshness elasticity is high, retailers share information horizontally, and both retailers share demand information with the 3PL. Moreover, when retailers share information with the 3PL and the information is endogenously transmitted to the supplier, the supply chain’s profit can be maximized.

These include offering Ship-from-Store (SFS) services to reduce delivery waiting times and launching the live-streaming channel to enrich the entertainment aspect of shopping. In practice, however, most retailers adopt one of two approaches: either providing SFS exclusively for the traditional online channel (OS strategy) or not offering SFS services at all (NS strategy). Only a small number of retailers extend SFS services to both traditional online and live-streaming channels simultaneously (DS strategy). The underlying reasons for this variation in SFS strategy adoption across different channels remain unclear. This paper develops an analytical model to investigate the optimal SFS strategies and corresponding pricing decisions for retailers operating with and without offline sales channels. Our findings reveal that the optimal SFS strategy is shaped by several key factors, including the unit cost of implementing SFS, the proportion of time-sensitive consumers, and the hassle cost incurred by consumers when purchasing via live-streaming.

This study anchors on the push–pull-mooring (PPM) framework to conceptualize disclosure not as a simple trade-off, but as a behavioral migration from a status quo of defensive non-disclosure to active sharing. Specifically, we identify perceived privacy invasion (PPI) and perceived information control (PIC) as push factors; perceived convenience (PC) and perceived information quality (PIQ) as pull factors; and previous privacy experience (PPE) and personal technological innovativeness (PTI) as mooring factors acting as direct psychological anchors. Drawing on 424 valid responses from a nationwide survey in China, we employed a hybrid approach—structural equation modeling (SEM) for linear effect testing and fuzzy-set qualitative comparative analysis (fsQCA) for configurational exploration. SEM results reveal that PPI, PIC, PIQ, and PTI exert significant direct effects on disclosure intention, while PC and PPE do not, highlighting a “Rationality Filter” where patients prioritize the “precision dividend” over mere functional ease. Complementarily, fsQCA identifies three equifinal configurations leading to high disclosure: system-optimized, low-barrier, and knowledge-empowered trajectories. These findings reveal a substitution effect between individual curiosity and systemic control, suggesting that information quality is the non-negotiable anchor of the AIMC value proposition.

As a critical form of healthcare e-commerce, online medical consultations (OMCs) have emerged as a promising avenue to facilitate CoC for patients with depression. However, the predominantly text-based nature of OMCs may constrain the transmission of nonverbal cues that are essential for mental health care. This study examines how voice messaging in OMCs affects CoC among patients with depression. Guided by signaling theory, we collected secondary data from a Chinese OMC platform and employed fixed-effects models to examine the effect of voice message count (signal intensity) on CoC and the moderating effects of physicians’ voice characteristics (signal clarity), including pitch, pause, and speed. We find that more voice messages are associated with higher CoC, consistent with voice functioning as a signal of physician effort and availability. Signal clarity moderates this effect: higher vocal pitch, fewer pauses, and slower speed each amplify the impact of voice count on CoC, indicating that signal intensity translates into patient adherence more effectively when signal clarity is high. These results extend signaling theory by identifying the interplay between signal intensity and signal clarity in shaping receiver responses in the OMC context and offer insights for leveraging voice to strengthen patient CoC in digital mental health care and promote platform sustainability in digital health e-commerce.</div></div>","PeriodicalId":50541,"journal":{"name":"Electronic Commerce Research and Applications","volume":"79 ","pages":"Article 101645"},"PeriodicalIF":6.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149140658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fraudulent entities – fake review accounts, payment fraud rings, and money laundering operations – often exploit the gap between carefully constructed profile attributes and their actual transaction behavior. Detecting such fraud in large-scale online transaction networks is challenging due to the scarcity of labeled fraud cases and the complex, multi-faceted nature of fraudulent behavior. We propose CSGAD, a semi-supervised graph-based fraud detection framework that models the inconsistency between two complementary views of entity behavior in e-commerce networks: (1) the <em>structural view</em>, encoding transaction connectivity patterns such as who transacts with whom and through which intermediaries, and (2) the <em>semantic view</em>, encoding account profile attributes and transaction characteristics. Our key insight is that legitimate e-commerce participants exhibit consistency between their network behavior and profile attributes, whereas fraudulent entities show characteristic cross-view divergence. CSGAD employs dual specialized encoders – a transaction pattern encoder based on Graph Convolutional Networks and an account profile encoder with controlled Laplacian smoothing – linked through an InfoNCE contrastive objective that maximizes cross-view mutual information. Extensive experiments on eight real-world datasets, including Amazon product review networks (13K+ entities; collected 2014–2015), the T-Finance online payment platform (39K accounts; collected 2019–2020), the Elliptic Bitcoin transaction network (203K transactions; January–September 2019), and the DGraph digital commerce network (3.7M users; collected 2020–2021), demonstrate state-of-the-art fraud detection. Notably, CSGAD achieves 3.9% and 3.6% AUROC improvements on T-Finance and Elliptic over the strongest baseline (SpaceGNN), while requiring only 1%–5% labeled fraud cases. A detailed case study on Amazon review networks confirms that CSGAD identifies coordinated fake review clusters by detecting profile-behavior inconsistencies that conventional methods miss.
