BackgroundSocial media addiction has increasingly been a critical social problem. We explored the association between peer pressure on mobile phone use and adolescent mobile social media addiction and tested whether self-esteem and self-concept clarity could buffer the effect of peer pressure.Methods830 adolescents (Mage = 14.480, SDage = 1.789) participated in our anonymous cross-sectional questionnaire study.ResultsThe results showed that peer pressure significantly predicted adolescent mobile social media addiction. Self-esteem moderated the effect of peer pressure on mobile social media addiction in that peer pressure had a weaker effect for adolescents with higher self-esteem. Self-concept clarity moderated the effect of peer pressure on mobile social media addiction in that peer pressure had a weaker effect for adolescents with higher self-esteem. The two moderators also interact in that the moderation of self-esteem was stronger for adolescents with higher self-concept clarity and the moderation of self-concept clarity for adolescents with higher self-esteem.ConclusionThe results highlight the critical role of self-esteem and self-concept clarity in buffering the impact of peer pressure on mobile social media addiction. The findings promote a better understanding of how to buffer the undesirable effect of peer pressure and reduce the risk of mobile social media addiction among adolescents.

Increasingly complex domestic and international affairs have pushed the Chinese government to seek think tanks' intellectual support for "scientific policy making." While a number of authors have explored the mechanisms through which Chinese think tanks influence policy making, little is known about how the Chinese central authorities gradually came to accept and to promote the idea to construct "New-Type Think Tanks with Chinese Characteristics" (NTTTCC), i.e. the current policy line on domestic think tank development. Against the backdrop of the evolution of think tanks in China since the beginning of economic reform and opening-up in 1978, this paper traces the development of the new policy line on think tanks and its underlying ideas. The concept of think tanks got introduced into Chinese academic discourse in the 1990s, which also saw the start of studies on such organizations in China. Scholars increasingly considered how Chinese think tanks could explore their own distinct developmental approach, rather than just following Western templates, while global think tank rankings encouraged Chinese domestic think tanks compete with each other. The Global Financial Crisis also made the Chinese leadership realize the shortage of high quality policy analysis by existing think tanks. A window of opportunity for a new policy on think tanks finally opened up when new President Xi Jinping embraced in 2013 a research report on think tanks by the Development Research Center of the State Council. By late 2015, the new policy had led to the selection of 25 "pilot top think tanks" endowed with substantial top-up government funding in support of their research.
