背景：随着我国老龄化、信息化社会的快速发展，尤其是在新冠疫情的持续影响下，人们的出行都需要网络设备的支持，因此迎接互联网，适应互联网，是人们的必然选择。老年人也渴望融入快速发展的社会，享受网络社会为他们提供的便利。老年人通过使用互联网解决日常生活中的难题并不断拓宽社会支持网络，增强社会保障，提升社会阶层，加强社会交往，改善老年人生活质量，提升其生活幸福感，推动我国老年社会工作向更好的方面迈进。但是互联网的使用对于老年人主观幸福感提升并非一直是积极的影响，因此有必要探究互联网使用、社会支持以及老年人主观幸福感三者的关系与相互影响，为社会工作介入老年人主观幸福感的的提升提供科学依据。

目的：主要是为了对60岁及以上老年人互联网使用、社会支持以及老年人主观幸福感有关实证数据进行分析，探究互联网使用和社会支持对老年人主观幸福感的影响以及社会支持在互联网使用与老年人主观幸福感之间的中介作用以上三者之间的逻辑关系，老人拥有的支持在网络应用与老人主观幸福感方面是否发挥着中介效应，这对于老年人互联网的学习与网络知识与技能的提升具有的学习动力重要的作用，使老人学会运用互联网为实际生活需求服务，在实践中运用并服务生活实际需要，巩固和强化老年人的社会支持网络，提高老年人的日常生活质量，增强其主观幸福感，对于促进老年人身心健康具有积极意义。

研究方法：本文运用2017年中国社会调查研究中心的数据，研究对象选取60岁及以上的老人，样本共有3747个，采用SPSS26.0数据分析软件对所选样本进行分析研究，通过关键变量和人口统计学变量进行描述性统计分析、相关性分析、分层回归以及结构方程模型中介检验等方式来探究互联网使用、社会支持以及老年人主观幸福感三者间的相互作用。

研究结果：第一，互联网使用对老年人主观幸福感具有显著正向影响，互联网使用会促进老年人主观幸福感的提升。第二，互联网使用对于社会支持具有显著正向性影响，随着老年人互联网使用的增加社会支持的水平会逐渐提升，互联网使用频率和闲暇时使用互联网正向影响社会支持。互联网是主要信息来源负向影响社会支持。第三，社会支持与老年人主观幸福感具有显著正向影响相关性。社会支持的增加，老年人主观幸福感也会随之增强社会支持中的社会交往与主观幸福感具有负相关关系，社会阶层与社会保障与主观幸福感具有正相关关系。第四，中介效应模型分析显示，互联网使用通过社会支持对老年人产生影响，即社会支持在互联网使用与老年人主观幸福感之间具有部分中介作用。

研究建议：社会工作在致力于提升老年人互联网使用水平方面，要防止两类现象的出现，既要防止老年人被数字化时代所抛弃，又要防止老年人沉迷于网络世界中。为了提高老年人主观幸福感，社会工作者应当多角度全方位考虑，积极做好政策影响者推动老年人“触网”相关政策的制定，不断完善老年人社会支持网络，打造良好的网络社会环境，深入了解老年人的需求，调动老年人参与社会活动的热情，扩大社交网络，巩固社会支持力度，从而推动积极健康的老龄化社会，为提高老年人主观幸福感营造良好的社会氛围。
