In the new era of sustainable urban development, neighbourhood renewal has received increasing attention. Social capital, which can be defined as the value embedded in the relationship between residents, plays a significant role in the process of neighbourhood renewal. However, within the current neighbourhood renewal knowledge domain, there is a lack of clear and systematic understanding of the various components that make up social capital, how they are formed, and how they impact neighbourhood renewal. With the rise in neighbourhood renewal projects worldwide, it has become increasingly important to facilitate better knowledge in this area. To this end, this study focuses on filling this knowledge gap. First, based on the review of 84 journal papers related to social capital in neighbourhood renewal, a research framework is developed for analysing social capital in the context of neighbour renewal. Using this framework as a lens, a critical review of the literature is then conducted. Finally, through an in-depth discussion, this study presents the main concepts of social capital, its formulation and its association with neighbourhood renewal. This review paper can be used as an important reference for researchers globally interested in the topic of social capital in neighbourhood renewal.
