【摘要】 家庭是人口高质量发展的微观载体，婚姻稳定性与生育意愿关乎家庭的存续与发展，也是观察社会变迁的重要维度，互联网使用情况则对二者产生深刻影响。基于2021年中国综合社会调查(CGSS)数据，运用二元Logistic和OLS回归模型，探究互联网使用对居民婚姻稳定性与生育意愿的影响及作用机制，并分析群体异质性。研究发现，互联网使用显著降低居民婚姻稳定性与生育意愿，且该结论经工具变量法、替换核心解释变量等内生性与稳健性检验后仍成立。从群体差异看，互联网使用对“60后”“70后”及女性婚姻稳定性的降低作用更显著，对“70后”及女性生育意愿的抑制效果更明显。机制分析表明，性别角色观念在其中发挥部分中介作用，即互联网使用通过提升性别角色观念现代化水平间接降低婚姻稳定性、抑制生育意愿。建议通过网络弘扬健康婚育观，构建适配现代性别观念的政策支持体系，支持和科学指导中高龄及女性群体使用互联网，以提升家庭福祉与社会可持续发展能力。更多还原

【Abstract】 The family serves as a medium for observing the high-quality development of population. The stability of marriage and the willingness to have children are crucial for the continuation and development of the family,and they are also important dimensions for observing social changes. The Internet use has a profound impact on both of these aspects. Based on the 2021 China General Social Survey( CGSS) data,using binary Logistic and OLS regression models,this study explores the impact and mechanism of Internet use on the marital stability and fertility intentions of residents,and analyzes the heterogeneity of the population. The research finds that Internet use significantly reduces the stability of residents’ marriages and their willingness to have children. Moreover,this conclusion remains valid even after undergoing endogeneity and robustness tests using instrumental variable methods and replacing the core explanatory variables. The mechanism analysis indicates that gender perceptions( including gender capacity identity and gender division of labor identity)play a partial mediating role in this process,that is,Internet use indirectly reduces marital stability and suppresses the desire for having children by enhancing the modernization level of gender perceptions. Based on this,the research suggests promoting a healthy concept of marriage and childbearing through the Internet,establishing a policy support system that is compatible with modern gender perceptions,and paying attention to the guidance on Internet use for middle-aged and elderly groups as well as women,in order to enhance family well-being and the sustainable development capabilities of society.更多还原
