Abstract
PurposeThis paper analyzes and illustrates the spatial distribution of publications in international urban planning journals from 2010 to 2020.Design/methodology/approachThe study employs the Biblioshiny bibliometrix package in R to analyze 44,123 articles from 95 international planning journals. To conduct the spatial scientometric analysis, we adopted the United Nations’ geoscheme focusing on three geographical scales: country, subregion, and region. Collaboration patterns at the country and subregional levels were examined using the VOSviewer tool.FindingsThe study found evidence of a spatial polarization of urban planning scholarly knowledge production. Scholars based in the United States and the United Kingdom consistently published at higher rates than any other country in our data set. The region producing the largest number of publications was Europe, consisting of 39.92% of the total publication count. However, urban planning scholars from the Global South authored only 20.96% of planning publications from 2010–2020. Centralization of planning research is also evident within each region and subregion. As such, both the Global North and the Global South should not be framed as homogenous entities and spatial patterns of knowledge production should not be generalized. The analysis also established the emerging role of Northern America as a major collaborator in inter-country and inter-subregional research collaborations. Co-authorship patterns indicate low intra-regional collaboration in planning research, except for Europe.Originality/valueThis article argues that a culture of exclusivity may be occurring in urban planning publication production. By highlighting the spatial disparities in knowledge production, we emphasize the need to examine the structural and institutional barriers that exclude urban planning knowledge emerging from the peripheries in international planning journals.
