Abstract: “SRDI” small and medium-sized enterprises (S-SMEs) are an important vehicle for implementing innovation-driven strategies. In view of the lack of research on the micro-level of S-SMEs' innovation performance in academic circles, this paper examines the significant key factors and configuration effect that influence S-SMEs' innovation performance from the perspective of complex causal effect analysis, mixing NCA, empirical regression and QCA methods, and refines the corresponding improvement paths. It is found that (1) R&D capability, financing environment and market competitiveness significantly affect the innovation performance of S-SMEs; (2) there are five configuration paths that enhance the innovation performance of different types of S-SMEs; (3) when financing is blocked, either small-scale production or improving their own market competitiveness can enable S-SMEs to maintain a high level of innovation performance target. This paper attempts a new way of thinking of complex causal effect analysis, which provides some theoretical and practical references for the study of S-SMEs' innovation performance in the future.

摘要： “专精特新”中小企业是实施创新驱动战略的重要载体。鉴于学界缺少对其创新绩效微观层面的研究，本文从复杂因果效应分析的视角出发，混合NCA、实证回归与QCA方法，考察影响“专精特新”中小企业创新绩效的显著关键条件与组态效应，并提炼相应的提升路径。研究发现：（1）研发能力、融资环境与市场竞争力会显著影响“专精特新”中小企业的创新绩效；（2）存在5条提升不同类型“专精特新”中小企业创新绩效的组态路径；（3）在融资受阻时，小规模生产或提高自身市场竞争力都可使“专精特新”中小企业继续保持高水平的创新绩效。本文尝试了一种复杂因果效应分析的新思考，为“专精特新”中小企业创新绩效的未来研究提供了一定的理论与实践参考。
