The keyword co-occurrence overlay network shows relationships among research themes in business-to-business relationship literature. Nodes represent keywords and connecting lines represent co-occurrence relationships. Prominent keywords include B 2 B Relationship, Opportunism, Trust, Contracts, Performance, Supply Chain, Innovation, Governance, Networks, Knowledge, Risk, and Alliance. The size of each node reflects its prominence within the network. A colour scale ranging from approximately 40 to 140 indicates varying levels of occurrence or impact across the keywords. B 2 B Relationship forms the central hub connecting multiple themes related to governance, performance, trust, collaboration, supply chains, innovation, and risk. Dense interconnections among nodes illustrate the multidisciplinary and highly connected nature of the research field.Keyword co-occurrence based on citation count of the top 50 keywords
Note(s): Larger nodes such as “B2B relationship,” “opportunism” and “supply chain” indicate central topics with high frequency and influence. Colors represent citation frequency: yellow indicates more frequently cited keywords; dark blue/purple indicates less frequently cited keywords (100 = average)
