This study aimed to understand the digital divide in Korea by analyzing the digital competence and Internet use/behavior of persons with disabilities (PwD) in the context of PC and smart device use. Data from the 2018 Information Divide Index compiled by the South Korean National Information Society Agency were analyzed. The sample included both PwD and non-disabled populations. The disabled group was further divided by type of disability. We identified the domains that defined competence and Internet use/behavior. Access rates for both PCs and smart devices were also analyzed. Competence and Internet use/behavior varied among PwD. The results showed that the use of smart devices aggravates the information divide among PwD, and its effect varies by type of disability. When controlling for socioeconomic characteristics, lower-limb physical disabilities did not negatively affect competency or Internet use/behavior. These findings have implications for further research as well as policy and practice. Strategies to reduce the information divide for PwD should be responsive to the type of disability and environment of PwD.

这项研究旨在通过分析PC和智能设备使用环境下的数字能力以及残疾人的互联网使用/行为来了解韩国的数字鸿沟。分析了来自韩国国家信息社会机构的2018年信息鸿沟指数。样本包括PwD和非残障人群。残疾组进一步按残疾类型划分。我们确定了定义能力和互联网使用/行为的领域。还分析了PC和智能设备的访问速率。残疾人的能力和互联网使用/行为各不相同。结果表明，智能设备的使用加剧了PwD之间的信息鸿沟，其影响因残疾类型而异。在控制社会经济特征时，下肢肢体残疾不会对能力或互联网使用/行为产生负面影响。这些发现对进一步的研究以及政策和实践具有启示意义。减少PwD信息鸿沟的策略应针对PwD的残障类型和环境。
