研发投资的空间集聚有利于溢出知识、节约成本、降低风险、共享资源。以中国省市为空间样本,采用空间自相关Moran指数及集聚分析的空间计量经济学方法,研究了在华跨国公司研发投资的空间溢出效应及区位决定因素。结果发现,在溢出空间性等集聚内生因素作用下,中国省域跨国公司研发投资行为在空间分布上存在交互作用,表现为明显的区域投资集聚现象;在形成空间集聚的各因素中,除市场规模、人才资源等需求和供给因素外,集聚因素本身也有重要影响。 The spatial agglomeration of R & D investment helps to spill knowledge, save costs, reduce risks and share resources. Taking China’s provinces and cities as a spatial sample, this paper studies the spillover effects and location determinants of R & D investment by multinationals in China using the spatial autocorrelation Moran index and the spatial econometric method of agglomeration analysis. The results show that under the action of agglomeration endogenous factors such as spillover spatiality, the R & D investment behavior of China’s provincial MNCs has an interaction on the spatial distribution, showing obvious regional investment agglomeration. Among the factors that form spatial agglomeration, Market size, human resources and other demand and supply factors, the agglomeration factor itself has a significant impact.
