Based on accessibility analysis, this study evaluated the inclusive environment of the waterfront space of Suzhou River in Shanghai from the perspective of the elderly in the community. The urban network analysis (UNA) and AHP methods are used to analyze the spatial samples. An inclusive evaluation system is constructed based on seven fundamental characteristic indexes, and the evaluation results are compared. The analysis shows that the waterfront space of Suzhou River has good accessibility, and there are differences in the demand for use between the activities of tourists and residents in some river sections. The daily activities of residents in the informal space and the contradictory feelings for Suzhou River before the regeneration reflect the complexity of the inclusive environment of the waterfront space. On this basis, three types of waterfront spaces were evaluated, and suggestions were put forward, including optimizing supply, compound utilization, and enhancing place attachment. This study will help to understand the inclusive value of waterfront regeneration, which has positive significance for improving the planning and construction of waterfront space and promoting social justice.
