摘　　要：企业研发投入和区位决策的策略性互动是决定企业市场势力和盈利能力的重要因素,并对行业均衡研发水平产生实际影响。本文基于企业间存在知识溢出的假设,构建空间古诺竞争模型,分析地理邻近性对企业研发激励的作用,并运用中国工业企业数据对研究结论进行检验。研究结果表明,在空间产量竞争中,知识溢出能够加速企业的空间集聚,地理邻近性的上升能够提高企业的研发激励。研究结论对于指导创新空间政策的制定具有一定的参考,制定政策时需要充分考虑行业的竞争差异性。The strategic interaction between enterprise research and development(R&D) investment and district committee decision-making is an important factor to determine the enterprise market power and profitability, and has a practical impact on the balanced R&D level of the industry. Based on the assumption that knowledge spillover exists among enterprises, this paper constructs a spatial cournot competition model and discusses the relation of geographical proximity and R&D incentive of enterprises. The hypothesis is tested using the Chinese industry enterprises’ data. The results show that knowledge spillover will make enterprises tend to agglomerate, and the R&D expenditure of enterprises increases with the decrease of the distance between enterprises if they compete in quantity. The spatial policy of innovation for different industries with different competitive characteristics needs to be formulated separately.
