Abstract: Questionnaire survey was conducted on the electronic word-of-mouth（eWOM） information published on post-90s student catering network platfor, and the relationship between communication motivation and eWOM information content expression was analyzed from the perspective of senders. The results show that satisfaction is not related to the content of eWOM information. Altruism, interest-motivation and the objectivity of online word-of-mouth information are positively correlated. Altruism, self-improvement and interest motives are positively related to the interest of eWOM information. It is recommended that catering enterprises focus on guiding and stimulating the intrinsic motivation of the sender, ensuring more interesting and objective eWOM information presentation, and providing consumers with more realistic consumer guidance.

Key words: eWOM, communication motivation, objectivity, interest
