Digital Disconnect Version 1

This study examines the impact of perceived infrastructural support and digital skills on user engagement with Nigeria's Digital Switchover (DSO). It investigates if digital skills mediate the relationship between infrastructural readiness and participation in this national digital broadcasting reform. Utilising a cross-sectional survey and structural equation modelling, the research tests both direct and mediating relationships among these factors. The results show that perceived infrastructural support strongly predicts DSO engagement and digital skills, underscoring the centrality of structural readiness in digital transition processes. In contrast, digital skills do not significantly predict engagement, and no mediating effect is observed. The findings suggest that infrastructural conditions have a more significant impact on DSO participation than individual digital skills. Uneven infrastructure limits the effectiveness of digital competencies. The study recommends an infrastructure-first approach to DSO implementation, followed by focused skill-building. It also encourages future research on integrating geospatial infrastructure data and cross-platform digital skills.本研究探讨了感知基础设施支持与数字技能对尼日利亚数字切换（Digital Switchover, DSO）用户参与度的影响，旨在检验数字技能是否在基础设施就绪度与这项全国性数字广播改革的参与度之间发挥中介作用。本研究采用横断面调查与结构方程建模方法，对上述因素间的直接效应与中介效应关系进行了检验。研究结果显示，感知基础设施支持对数字切换参与度与数字技能均具有显著预测作用，凸显了基础设施就绪度在数字转型进程中的核心地位。相较而言，数字技能对用户参与度并无显著预测作用，且未观测到中介效应。研究结果表明，基础设施条件对数字切换参与度的影响程度显著高于个体数字技能；基础设施分布不均会制约数字素养的应用成效。本研究建议在数字切换实施过程中采用基础设施优先的策略，随后再开展针对性的技能培养工作，同时呼吁未来可开展整合地理空间基础设施数据与跨平台数字技能的相关研究。
