Existing research focuses on the direct effects of online comments on product sales, whereas studies on the spillover effects of online comments are relatively limited, especially for high-involvement products. This study explores the impact of online comments of competing products on focal product sales in high-involvement products.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Design\/methodology\/approach<\/jats:title><jats:p>Data mining techniques are used to collect 72,367 online comments from the Autohome platform, and sentiment analysis algorithms are used to quantify the textual information for subsequent analysis. Specifically, two panel two-way fixed-effects models are constructed to explore the impact of the average valence and quantity of online comments of competing cars on focal car sales, and analyse this impact in terms of heterogeneity across car price levels, while the moderating effect of online comments of competing cars is explored.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Findings<\/jats:title><jats:p>The results show that the average quantity of online comments of competing cars has a significant effect on the sales of the focal car in the overall sample, while the average valence of online comments of competing cars does not have a significant spillover effect. Moreover, the spillover effect varies by car price level. For high-priced cars, the average quantity of online comments of competing cars significantly and negatively affects focal car sales, and the average valence of online comments of competing cars significantly and negatively moderates the effect of the valence of focal car online comments on its sales. For lower-priced cars, online comments of competing cars don\u2019t significantly affect focal car sales.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>This study not only enriches the theory of online comments and high-involvement product sales, but also provides reference and guidance for exploring spillover effects of online comments for other products.<\/jats:p><\/jats:sec>","DOI":"10.1108\/imds-01-2024-0015","type":"journal-article","created":{"date-parts":[[2024,7,25]],"date-time":"2024-07-25T21:59:21Z","timestamp":1721944761000},"page":"2791-2814","source":"Crossref","is-referenced-by-count":2,"title":["Spillover effects of online comments on high-involvement product sales: evidence from the\u00a0Chinese automobile industry"],"prefix":"10.1108","volume":"124","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1784-5221","authenticated-orcid":false,"given":"Shutian","family":"Wang","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6888-5579","authenticated-orcid":false,"given":"Yan","family":"Lin","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5446-3073","authenticated-orcid":false,"given":"Lu","family":"Yan","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9318-255X","authenticated-orcid":false,"given":"Guoqing","family":"Zhu","sequence":"additional","affiliation":[]}],"member":"140","published-online":{"date-parts":[[2024,7,25]]},"reference":[{"issue":"4","key":"key2024082711120091000_ref001","doi-asserted-by":"publisher","first-page":"458","DOI":"10.1509\/jmkr.38.4.458.18903","article-title":"The moderating role of commitment on the spillover effect of marketing communications","volume":"38","year":"2001","journal-title":"Journal of Marketing Research"},{"issue":"2","key":"key2024082711120091000_ref002","doi-asserted-by":"publisher","first-page":"143","DOI":"10.1509\/jmr.13.0009","article-title":"Halo (spillover) effects in social media: do product recalls of one brand hurt or help rival brands?","volume":"53","year":"2016","journal-title":"Journal of Marketing Research"},{"issue":"1","key":"key2024082711120091000_ref003","doi-asserted-by":"publisher","first-page":"89","DOI":"10.1287\/mksc.2016.1001","article-title":"Spillover effects in seeded word-of-mouth marketing campaigns","volume":"36","year":"2017","journal-title":"Marketing Science"},{"key":"key2024082711120091000_ref004","first-page":"129","article-title":"Online reviews: do consumers use them?","volume":"28","year":"2001","journal-title":"Advances in Consumer Research"},{"issue":"3","key":"key2024082711120091000_ref005","doi-asserted-by":"publisher","first-page":"477","DOI":"10.1287\/mnsc.1070.0810","article-title":"Online consumer review: word-of-mouth as a new element of marketing communication mix","volume":"54","year":"2008","journal-title":"Management Science"},{"issue":"1","key":"key2024082711120091000_ref006","doi-asserted-by":"publisher","first-page":"637","DOI":"10.1080\/1331677x.2021.1931910","article-title":"How electronic word of mouth dynamically influences product sales and supplies: an evidence from China film industry","volume":"35","year":"2022","journal-title":"Economic Research-Ekonomska Istra\u017eivanja"},{"key":"key2024082711120091000_ref007","unstructured":"CPCA (2022), \u201cNational passenger vehicle market in-depth analysis report for December 2022\u201d, available at: http:\/\/www.cpcaauto.com\/newslist.php?types=csjd&id=2989"},{"key":"key2024082711120091000_ref008","doi-asserted-by":"publisher","first-page":"74","DOI":"10.1016\/j.jretconser.2018.08.003","article-title":"Effects of online review positiveness and review score inconsistency on sales: a comparison by product involvement","volume":"45","year":"2018","journal-title":"Journal of Retailing and Consumer Services"},{"issue":"6","key":"key2024082711120091000_ref009","doi-asserted-by":"publisher","first-page":"1261","DOI":"10.1016\/j.jbusres.2014.11.006","article-title":"What makes online reviews helpful?
