• Abstract:Against the backdrop of a new wave of technological revolution and industrial transformation, cross-border R&D investments have become increasingly frequent, forming a complex global network structure. Existing studies mostly focus on changes in cross-border R&D investment stock, with limited attention to the relationships between cross-border R&D investments among countries. and fail to take into account the influence of the geopolitics on the evolution of its structure. This paper uses cross-border R&D investment data from 2003 to 2022 recorded in the fDi Markets database to construct a global cross-border R&D investment network. It analyzes the evolutionary characteristics of the network's topological, spatial, and relational structures and employs econometric models to quantitatively reveal the factors influencing network structure evolution. The results show that: (1) In terms of topological structure, the scale and density of the global cross-border R&D investment network have increased rapidly. The network’s outdegree connections exhibit a clear trend of decentralization, while the indegree connections show an enhanced degree of clustering. (2) In terms of spatial structure, while the triangle pattern formed by North America, Western Europe, and East Asia has developed steadily, the rise of emerging countries has driven the initial emergence of a global multipolar pattern. The network connections are always based on the interregional connections, and he network exhibits no significant spatial homogeneity. (3) In terms of relational structure, the global cross-border R&D investment network exhibits a multi-core interconnected structure of core-periphery relations, where developed countries in Europe and North America occupy the core positions of the network. (4) In terms of influencing factors, the evolution of global cross-border R&D investment network structure is affected by the enterprise investment motivation, location factor endowment and geopolitical factors, among which the variables of national market and economy, technology and knowledge, R&D personnel and foundation show a significant positive driving effect, and international trade sanction and financial sanction show a negative inhibiting effect. There is also a significant difference between the influencing factors of outdegree and indegree networks, with a negative correlation between R&D personnel and the centrality of outdegree networks, and a negative influence of economic development, technological innovation, and the R&D base environment on the centrality of indegree networks.
