Well-organized question threads in online Q&amp;A communities enable users to clearly read existing answers and their evaluations before contributing. Based on the social comparison and peer influence literature, the authors examine peer influence on the informativeness of knowledge contributions in competitive settings. The authors also consider three levels of moderating factors concerning individuals' perception of competitiveness: question level, thread level and contributor level.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Design\/methodology\/approach<\/jats:title><jats:p>The authors collected data from one of the largest online Q&amp;A communities in China. The hypotheses were validated using hierarchical linear models with cross-classified random effects. The generalized propensity score weighting method was employed for the robustness check.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Findings<\/jats:title><jats:p>The authors demonstrate the peer influence due to social comparison concerns among knowledge contribution behaviors in the same question thread. If more prior knowledge contributors choose to contribute long answers in the question thread, the subsequent contributions are more informative. This peer influence is stronger for factual questions and questions with higher popularity of answering but weaker in recommendation-type and well-answered questions and for contributors with higher social status.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>This research provides a new cue of peer influence on online UGC contributions in competitive settings initiated by social comparison concerns. Additionally, the authors identify three levels of moderating factors (question level, thread level and contributor level) that are specific to online Q&amp;A settings and are related to a contributor's perception of competitiveness, which affect the direct effect of peer influence on knowledge contributions. Rather than focus on motivation and quality evaluation, the authors concentrate on the specific content of online knowledge contributions. Peer influence here is not based on an actual acquaintance or a following relationship but on answering the same question. The authors also illustrate the competitive peer influence in subjective and personalized behaviors in online UGC communities.<\/jats:p><\/jats:sec>","DOI":"10.1108\/intr-07-2022-0510","type":"journal-article","created":{"date-parts":[[2023,6,19]],"date-time":"2023-06-19T06:09:58Z","timestamp":1687154998000},"page":"1577-1601","source":"Crossref","is-referenced-by-count":17,"title":["Competitive peer influence on knowledge contribution behaviors in online Q&amp;A communities: a\u00a0social comparison perspective"],"prefix":"10.1108","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1052-1200","authenticated-orcid":false,"given":"Chencheng","family":"Shi","sequence":"first","affiliation":[]},{"given":"Ping","family":"Hu","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1272-5538","authenticated-orcid":false,"given":"Weiguo","family":"Fan","sequence":"additional","affiliation":[]},{"given":"Liangfei","family":"Qiu","sequence":"additional","affiliation":[]}],"member":"140","published-online":{"date-parts":[[2023,6,20]]},"reference":[{"issue":"7","key":"key2024092806302663500_ref001","doi-asserted-by":"crossref","first-page":"2054","DOI":"10.1287\/mnsc.2015.2253","article-title":"Cumulative growth in user-generated content production: evidence from Wikipedia","volume":"62","year":"2016","journal-title":"Management Science"},{"issue":"4","key":"key2024092806302663500_ref002","doi-asserted-by":"crossref","first-page":"1214","DOI":"10.1287\/isre.2021.1020","article-title":"Learning to be creative: a mutually exciting spatiotemporal point process model for idea generation in open innovation","volume":"32","year":"2021","journal-title":"Information Systems Research"},{"issue":"ahead-of-print","key":"key2024092806302663500_ref003","doi-asserted-by":"publisher","DOI":"10.1108\/INTR-08-2022-0594","article-title":"An empirical examination of newcomer contribution costs in established OSS communities: a knowledge-based perspective","volume":"ahead-of-print","year":"2023","journal-title":"Internet Research"},{"issue":"1","key":"key2024092806302663500_ref004","doi-asserted-by":"crossref","first-page":"6","DOI":"10.1287\/isre.2015.0618","article-title":"On the longitudinal effects of IT use on firm-level employment","volume":"27","year":"2016","journal-title":"Information Systems Research"},{"issue":"2","key":"key2024092806302663500_ref005","doi-asserted-by":"crossref","first-page":"425","DOI":"10.25300\/MISQ\/2019\/14530","article-title":"Nurturing online communities: an empirical investigation","volume":"43","year":"2019","journal-title":"MIS Quarterly"},{"issue":"4","key":"key2024092806302663500_ref006","doi-asserted-by":"crossref","first-page":"1245","DOI":"10.25300\/MISQ\/2014\/38.4.14","article-title":"Knowledge exchange and symbolic action in social media-enabled electronic networks of practice: a multilevel perspective on knowledge seekers and contributors","volume":"38","year":"2014","journal-title":"MIS Quarterly"},{"key":"key2024092806302663500_ref007","first-page":"993","article-title":"Latent Dirichlet\u00a0allocation","volume":"3","year":"2003","journal-title":"Journal of Machine Learning Research"},{"issue":"5","key":"key2024092806302663500_ref008","doi-asserted-by":"crossref","first-page":"2065","DOI":"10.1287\/mnsc.2016.2715","article-title":"Stimulating online reviews by combining financial incentives and social norms","volume":"64","year":"2018","journal-title":"Management Science"},{"issue":"3","key":"key2024092806302663500_ref009","doi-asserted-by":"crossref","first-page":"702","DOI":"10.1086\/521848","article-title":"Complex contagions and the weakness of long ties","volume":"113","year":"2007","journal-title":"American Journal of Sociology"},{"issue":"1","key":"key2024092806302663500_ref010","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1016\/j.im.2010.11.001","article-title":"Social capital and individual motivations on knowledge sharing: participant involvement as a moderator","volume":"48","year":"2011","journal-title":"Information and Management"},{"key":"key2024092806302663500_ref011","doi-asserted-by":"crossref","first-page":"226","DOI":"10.1016\/j.im.2010.03.001","article-title":"To give or to receive?
