摘　　要：文章基于企业在技术领域内集聚的视角,使用DO指数测度了企业集聚的范围,并依此构建空间权重矩阵,从显性知识溢出和隐性知识溢出两个角度探索了长三角科技型中小企业间知识溢出的存在性和机制。研究发现:区域中技术领域内的科技型中小企业数量成规模或技术有优势,集聚的企业间才会有显性知识溢出效应;科技型中小企业在集聚的情况下,研发人力投入具有正向且显著的隐性知识溢出效应;由于普适性研发奖励政策以及科技型中小企业研发投入的“被动”性,科技型中小企业的研发资本投入具有挤出效应,使得研发资本不能带动企业间产生显著正向的知识溢出。研究结论为引导科技型中小企业集聚促进其知识溢出效应、科技型中小企业研发投入的补贴政策带来了一定的启示。Based on the perspective of enterprise agglomeration in the technical field,the essay uses the DO index to measure the range of enterprise agglomeration and constructs a spatial weight matrix accordingly.From the perspectives of explicit knowledge spillover and implicit knowledge spillover,it explores the existence and relevant mechanism of knowledge spillover among technology-based SMEs in the Yangtze River Delta.Findings:In the region only when,technology-based SMEs in the technical sector form a large scale and possess technical advantages,there will be an explicit knowledge spillover effect among the clustered enterprises;when technology-based SMEs are clustered,their R&D human resource investment produces a positive and significant implicit knowledge spillover effect;Due to the general R&D incentive policies and the"passive"nature of R&D investment of technology-based SMEs,R&D capital investment of technologybased SMEs presents a crowding-out effect,preventing R&D capital from driving significant positive knowledge spillover among enterprises.The research findings provide certain insights for guiding the clustering of technology-based SMEs to promote their knowledge spillover effects,and for the subsidy policies on R&D investment of technology-based SMEs.
