This paper takes nine Media WeChat official accounts as cases，mainly using the content analysis method，to evaluate their social responsibility. Data results show that on the whole，maistream authority media’s social responsibility score highest，CCTV News，CCTV Finance and People’s Daily Online rank the top three. China Newsweek is the most significant on culture and education function，Guangzhou Daily is prominent on commercial activities and charitable activities，thus scores highest on coordinate relationship function. Because of the significant social and interactive characteristics of WeChat，most of the media WeChat official accounts pay more attention to improve the communication and interaction with users，and focus on providing service，so the function of information production is relatively secondary. It also exists the problem of lack of originality in media WeChat official accounts. As the professional information production organization，media WeChat official accounts should invest more in producing original content，and at the same time of providingbetter service and communication，still insist on providing quality and individual information products.
