The network displays multiple clusters of nodes, each represented by circles with labels, connected by thin lines indicating relationships. The labels are adjacent to the nodes. At the center-left, a cluster of nodes is visible with a large, darker node labeled “cao s.; nie l.; sun h; sun w.” Other nodes in this cluster include “yang x. (2022)” and “feng y.; zhang h.; li g. (2022).” Toward the upper center, a cluster is centered on “chen s.; zhang h. (2021)” and “li g.; chen h.; ma b. (2023).” In the lower center, there is a cluster with “su l.; peng y.; kong f.; chen x.; wu y.; huang s. (2022).” In the middle-right area, a cluster is centered on “ozili p.k. (2018).” This cluster connects to “gombet p.; koch j.-a.; siering.” The far right shows another cluster with “trivedi s.; mandal r.; sharma r.” and “gaiser b.; kroll t.; kroll k. (2013).”Bibliographic coupling based on documents’ interconnectedness. Note: Clusters of documents linked by shared references, showing thematic and intellectual proximity in digital finance.
