Research on Restraining Factors and Countermeasures of Old Residential Area Renovation Projects

In the context of urban renewal, the renovation of old residential communities has garnered significant attention from academia and policymakers as a crucial component of urban revitalization efforts. Facing multiple constraints during renovation processes, this study systematically identified 19 key limiting factors through literature analysis, case studies, and expert interviews to explore their underlying mechanisms. By applying the ISM model to construct hierarchical factor structures and employing the C-OWA operator for quantitative weight analysis, the research reveals five core constraints: policy standardization and regulatory completeness, rational renovation planning, resident satisfaction levels, government implementation intensity, and social capital participation. The study further delineates hierarchical transmission pathways among these critical factors. Based on these findings, a three-tiered policy framework is proposed, encompassing strengthened government coordination, improved policy standards, optimized design methodologies, enhanced resident satisfaction, and stimulated social capital engagement. This framework provides theoretical foundations and practical references for targeted interventions in old community renovation initiatives.
