The aim of this study is to examine the influence of using official WeChat accounts on repeat blood donation behavior.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Design\/methodology\/approach<\/jats:title><jats:p>This paper used the backstage operation data of official WeChat accounts and blood supply chain management system data from the blood bank for the study to analyze the changes in repeat blood donation behavior. First, to analyze the changes in the average frequency of blood donation per year, average volume of single blood donation and blood eligible rate of repeat blood donors before and after following the official WeChat accounts by difference-in-differences model combined with propensity score matching (PSM-DID). Second, we examined the impact of official WeChat accounts on the proportion of repeat blood donors through survival analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Findings<\/jats:title><jats:p>The results show that following WeChat accounts increases the average frequency of blood donation and blood eligible rate of repeat blood donors by 14.36% and 1.19%, respectively, and have no significant effect on the average volume of single blood donation. Further, WeChat accounts have a more significant impact on the average frequency of blood donations per year for workers, farmers, medical staff and groups with education levels of junior high school. In addition, official WeChat accounts can effectively increase the proportion of repeat donors.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>The results provide a quantitative basis for the influence of official WeChat accounts on repeat blood donation behaviors. On the one hand, it is of great significance to guide the publicity and recruitment of unpaid blood banks. On the other hand, it provides an evidence for the promotion of official WeChat accounts.<\/jats:p><\/jats:sec>","DOI":"10.1108\/imds-07-2020-0393","type":"journal-article","created":{"date-parts":[[2020,11,11]],"date-time":"2020-11-11T21:43:55Z","timestamp":1605131035000},"page":"192-208","source":"Crossref","is-referenced-by-count":10,"title":["Analysing repeat blood donation behavior via big data"],"prefix":"10.1108","volume":"121","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1252-2087","authenticated-orcid":false,"given":"Xu","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyu","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"140","reference":[{"issue":"4","key":"key2021021503362995700_ref001","first-page":"892","article-title":"Saving lives using social media: analysis of the role of Twitter for personal blood donation requests and dissemination","volume":"35","year":"2017","journal-title":"Telematics and Informatics"},{"key":"key2021021503362995700_ref002","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1016\/j.ijinfomgt.2018.06.001","article-title":"Investigating the impact of social media advertising features on customer purchase intention","volume":"42","year":"2018","journal-title":"International Journal of Information Management"},{"issue":"7","key":"key2021021503362995700_ref003","doi-asserted-by":"crossref","first-page":"1177","DOI":"10.1016\/j.tele.2017.05.008","article-title":"Social media in marketing: a review and analysis of the existing literature","volume":"34","year":"2017","journal-title":"Telematics and Informatics"},{"issue":"2","key":"key2021021503362995700_ref004","first-page":"269","article-title":"Managing blood donations with marketing","volume":"34","year":"2014","journal-title":"Social Science Electronic Publishing"},{"issue":"5","key":"key2021021503362995700_ref005","doi-asserted-by":"crossref","first-page":"945","DOI":"10.1016\/j.pubrev.2017.07.005","article-title":"Perceived values of branded mobile media, consumer engagement, business-consumer relationship quality and purchase intention: a study of WeChat in China","volume":"43","year":"2017","journal-title":"Public Relations Review"},{"key":"key2021021503362995700_ref006","article-title":"Evaluate the effects of the quality regulation on the pharmaceutical supply chain","volume":"230","year":"2020","journal-title":"International Journal of Production Economics"},{"issue":"3","key":"key2021021503362995700_ref007","first-page":"486","article-title":"Analyses of factors influencing Chinese repeated blood donation behavior: delivered value theory perspective","volume":"120","year":"2020","journal-title":"Industrial Management and Data Systems"},{"issue":"11","key":"key2021021503362995700_ref008","doi-asserted-by":"crossref","first-page":"3672","DOI":"10.1287\/mnsc.2016.2504","article-title":"Waiting to give: stated and revealed preferences","volume":"63","year":"2017","journal-title":"Management Science"},{"issue":"2","key":"key2021021503362995700_ref009","doi-asserted-by":"crossref","first-page":"294","DOI":"10.1111\/risa.12100","article-title":"A framework for understanding risk perception, explored from the perspective of the water practitioner","volume":"34","year":"2014","journal-title":"Risk Analysis"},{"issue":"3","key":"key2021021503362995700_ref010","doi-asserted-by":"crossref","first-page":"198","DOI":"10.1016\/j.ausmj.2016.04.001","article-title":"New versus frequent donors: exploring the behaviour of the most desirable donors","volume":"24","year":"2016","journal-title":"Australasian Marketing Journal"},{"issue":"2","key":"key2021021503362995700_ref011","doi-asserted-by":"crossref","first-page":"343","DOI":"10.1111\/j.1537-2995.2011.03279.x","article-title":"Exploring the pattern of blood donor beliefs in first-time, novice, and experienced donors: differentiating reluctant altruism, pure altruism, impure altruism, and warm glow","volume":"52","year":"2012","journal-title":"Transfusion"},{"issue":"3","key":"key2021021503362995700_ref012","doi-asserted-by":"crossref","first-page":"460","DOI":"10.1111\/trf.15633","article-title":"Can text messages save lives?
