1. Introduction
Urban development and economic growth are intricately intertwined, shaping the trajectory of cities worldwide [1]. As cities evolve into epicenters of economic activity, understanding the dynamics of economic development within urban settings becomes paramount [2]. Economic development in cities encompasses a complex interplay of factors, ranging from infrastructure investment to entrepreneurial ecosystems, from social equity to environmental sustainability [3]. Exploring these dynamics not only illuminates the forces propelling urban economies forward but also underscores the challenges and opportunities inherent in fostering inclusive and sustainable urban development.
Despite the wealth of literature on economic development and urbanization, certain gaps persist in our understanding of this multifaceted phenomenon. While numerous studies have examined economic development from macroeconomic perspectives, there remains a need for nuanced analyses that delve into the micro-level intricacies of urban economic dynamics. Moreover, the literature often overlooks the interdisciplinary nature of urban development, neglecting to integrate insights from diverse fields such as social sciences, environmental studies, and engineering.
In light of these gaps, there is a pressing need to conduct comprehensive bibliometric analyses to map the landscape of economic development research within cities. By synthesizing existing literature, identifying trends, and uncovering research priorities, such analyses can inform future scholarly endeavors and policy interventions aimed at fostering sustainable and inclusive urban economies.

Although this bibliometric review offers valuable insights into the changing research constituency of economic development in cities, it is important to recognize that it is not without its limitations. However, the value of the insights it provides should not be understated.
Most importantly, the analysis is limited to information obtained solely from Scopus. Scopus is a widely used international database that archives numerous scholarly publications; however, it does not include all possible relevant papers (especially non-indexed journals and regional titles with specific approaches concerning context-based urban economic development).
Secondly, the bibliometric method utilized quantitative indicators such as counts of publications and citations and citation indices that highlight where research appears through mapping theorematic clusters. Although these metrics offer a systematic method to quantify scholarly output and thematic change over time, they may not capture critical qualitative dimensions (e.g., the degree of analysis or level of contextual consideration that informs interpretation). In addition, the interpretation of thematic clusters detected by VOSviewer sheds light on prevailing research topics. Clustering approaches are based entirely on keyword co-occurrence patterns, which may oversimplify complex interdisciplinary interactions or overlook nascent and positively valued emerging issues in the academic literature.
Third, geographic and institutional analyses are only as good as the information contained in Scopus regarding author affiliations. Differences in the formatting of author affiliations or errors made during data input mean less precise geographic and organizational attributions, which could mislead conclusions regarding global research contributions.
Nevertheless, this study is intended to enrich the literature on urban economic development by providing an in-depth analysis of research trends, scholarly publication dynamics, and conversational landscapes. Future research must adopt a more comprehensive approach to further its understanding of urban economic development and guide evidence-based policy interventions. This includes using pluralistic data sources and qualitative methodologies that complement bibliometric analyses and tackle other spelled-out challenges in interdisciplinary work.
