The renovation of old neighborhood plays a pivotal role in augmenting the quality of life and catalyzing urban development. Currently, numerous old neighborhoods in China necessitate renovation due to insufficient maintenance and management, inadequate supporting infrastructure, and suboptimal energy efficiency. Despite extensive research and practical endeavors dedicated to old neighborhood renovation, a research gap in critical analysis emerged during the literature review. This study endeavors a comprehensive analysis to delineate the current state of renovation endeavors, elucidate barriers encountered, and propose innovative strategies to surmount these barriers. Firstly, this study provides a comprehensive overview of ongoing status of renovation efforts and their key focal points. Secondly, this study furnishes an encompassing summary of the fundamental aspects of old neighborhood renovation, encompassing sponge city renovation, environmental enhancement, building energy-efficient renovation, elevator installation, and modernizing elderly facilities and services. Furthermore, this paper meticulously analyzes the barriers such as stakeholder conflicts, resident skepticism, funding limitations, divergent perceptions, limited resident participation, and intricate decision-making processes. To solve these identified barriers, some targeted practical solutions are proposed including bolstering the governmental leadership, exploring diversified funding mechanisms, expanding policy implementation agents, improving resident communication, and establishing collaborative multi-party framework. These measures provide practical guidance to facilitate the seamless progression of renovation initiatives. This study aspires to furnish theoretical insights, practical guidance for policy formulation, and actionable recommendations for sustainable urban neighborhood renovation, contributing to the scholarly discourse and practice in this field.@en
