【摘要】 在健康中国战略背景下，文章利用中国综合社会调查(CGSS)2017年数据，采用多元有序Logistic回归模型探讨互联网使用频率对居民身心健康的影响作用及机制。结果显示：互联网使用频率可以直接促进居民身体、心理健康，也可以通过主观幸福感间接推动身心健康水平的提高，此结果通过了稳健性检验。异质性分析结果显示上述影响路径存在性别、年龄阶段、户籍差异；互联网使用频率对男性、中青年居民身体健康的正向影响明显强于对女性、老年居民的影响；互联网使用频率对青年居民心理健康的影响不显著；主观幸福感的中介效应仅在女性、中青年及农业户口居民中显著。因此，应审思互联网的正反双重功能，实现互联网高质量发展并促进居民身心健康。更多还原

【Abstract】 Under the circumstances of Healthy China Strategy this paper makes use of the 2017 data of Chinese General Social Survey(CGSS) and adopts the multinominal Logistic regression to explore the effect, role and mechanism of Internet use frequency on the citizens’ physical and mental health. The results of the analysis indicate that the Internet use frequency can directly facilitate the citizens’ physical and mental health and indirectly improve it through a subjective sense of happiness; the results have passed the robustness check. The heterogeneity analysis reveals that the above-mentioned effect paths display discrepancies in terms of gender, age range and registered household; the Internet use frequency has a stronger positive effect on the male population and the middle-aged and young people than on the female population and the elderly; the effect of Internet use frequency on the young people’s mental health is insignificant; the medium effect of subjective sense of happiness is significant only among the female population, the middle-aged and young people and the citizens of rural households. Therefore, it is necessary to examine the positive and negative effects of Internet and realize the high-quality Internet development and promote the citizens’ physical and mental health.更多还原
