Evaluating the Resilience of Urban–Rural Information Infrastructure Systems: A Hybrid Concept Lattice–DEMATEL–VIKOR Model in Shandong, China

Urban–rural information infrastructure (URII) serves as the backbone of the “Digital Village” strategy; however, it faces significant threats from natural disasters and socioeconomic disparities. This study proposes a comprehensive resilience evaluation framework based on the pressure–state–response (PSR) theory. To address the limitations of traditional subjective weighting, we construct an integrated assessment framework that combines the entropy weight method with an improved concept lattice-weighted cluster DEMATEL method, effectively handling cognitive differences among experts. Using Lijin County in Shandong Province as a case study, we assess resilience levels from 2018 to 2022 via the VIKOR method. The results indicate a robust upward trajectory in overall resilience, progressing from a low-level state in 2018 to a high-resilience state in 2022. However, a dimensional comparative analysis identifies pressure resilience as the most critical weak point; consequently, the study establishes that the priority for future resilience enhancement follows the order: pressure > state > response. Based on these findings, specific countermeasures focusing on disaster risk monitoring and infrastructure redundancy are proposed to foster sustainable rural digital development.
