Abstract:Investigating the factors influencing funding allocations in the top 2,500 Chinese enterprises involved in global research and development (R&D) expenditures significantly reveals the underlying motivations behind corporate strategies and decision-making processes, thereby providing theoretical support for enterprise management and policy formulation. Utilizing the sample of the top 2,500 Chinese firms in global R&D investment as published by the European Commission, this study employs various advanced metrics and models—including degree centrality, Gini coefficient, global spatial autocorrelation, local spatial autocorrelation, kernel density estimation, and spatiotemporal geographically weighted regression (GTWR)—to explore the characteristics of the uncontrolled distribution of R&D investments from both personnel and funding perspectives. Furthermore, it delves into how government support, the R&D environment, per capita GDP, and transportation conditions impact the intensity of R&D investment and the degree of corporate aggregation.The study reveals that Chinese enterprises among the global top 2,500 in R&D expenditures exhibit a distinct pattern of "more in the southeast, fewer in the northwest." R&D funding is concentrated in a small number of high-investment fields or institutions, while the spatial clustering of R&D personnel is more pronounced, indicating a certain degree of agglomeration. Government R&D internal expenditures and the number of research institutions are the primary factors influencing the number of sample enterprises. Therefore, the government must address potential issues of uneven distribution of talent and resources that may arise from this clustering, and encourage enterprises to strengthen the training and support of R&D personnel to improve their overall quality and promote a more balanced distribution.
