中文摘要：

上网对个人社会融合的影响是一个有争议的论题。文章使用2010年中国西部调查中陕西、广西两省（自治区）数据，从初级群体、次级群体两个维度考察上网时间与个人社会融合情况之间的关系。分析表明，上网时间的延长会增加个人的社会融合行为。同时，上网程度的加深会强化个人对初级群体的融合。这些结论初步揭示出上网对个人社会融合之间存在正相关关系。

英文摘要：

Social groups vary in time spent on the internet.This paper investigates the relationship between attributes of social groups and internet time spending,with an analytic focus on how internet use increases social integration.The anal-ysis of the Shaanxi and Guangxi portions of the 2010 Chinese Survey of Social Change（CSSC）shows that the people with higher education or higher household income spend more time on the internet,so do urban residents.In addition,mem-bers of social groups with fewer weak ties to others spend more time on the internet.These findings reveal a negative rela-tionship between internet time spending and degree of one′s integrated into greater society through interactions in the ac-tual,rather than virtual,social space.
