摘　　要：新产品对企业的商业成功至关重要,而作为企业知识基础的重要结构特征,知识替代性和互补性对企业技术创新的重要作用得到学者的一致认可,但缺乏其对企业新产品开发数量直接影响的研究,缺乏从企业内部技术多元化和外部知识产权保护视角分析知识替代性和互补性影响新产品开发数量的边界条件。基于知识重组理论和知识基础观的视角,以技术多元化和知识产权保护作为调节变量,构建知识替代性和互补性影响新产品开发数量的理论模型。以中国东部、中部和西部的574家车辆生产企业作为研究样本,采用Stata软件检验相应的假设并进行实证分析。研究结果表明,①知识替代性对新产品开发数量具有正向影响,知识互补性与新产品开发数量存在倒U形关系;②技术多元化对知识替代性与新产品开发数量之间关系起正向调节作用,对知识互补性与新产品开发数量之间关系的调节作用不显著;③知识产权保护对知识替代性与新产品开发数量之间关系具有正向调节作用,知识互补性与新产品开发数量之间的倒U形关系在知识产权保护弱的地区更为显著。研究结果发现知识替代性和互补性对新产品开发数量具有不同的作用,从知识元素的关系属性层面丰富了企业新产品开发前因变量的研究;发现技术多元化和知识产权保护对知识替代性和互补性与新产品开发数量之间关系的调节作用,为知识元素关系属性与新产品开发数量之间关系的权变因素的研究做出理论贡献。在实践方面,研究结果可以帮助企业管理者更合理地配置知识元素,并根据企业的技术多元化和知识产权保护调整新产品开发策略。New products are vital to the business success of a firm,as the important structural characteristics of a firm′s knowledge base,the important role of knowledge substitutability and knowledge complementarity in technological innovation of firms has been unanimously recognized by scholars,but it lacks the study of its direct impact on the number of new product development of firms.Also lack of analysis of the boundary conditions of the relationship between the knowledge substitutability and knowledge complementarity affecting the number of new product development from the perspective of technological diversity within the firm and the protection of intellectual property rights outside.From the perspective of knowledge recombinant theory and knowledge-based view,we take technological diversity and local intellectual property protection as the moderators,and then construct the theoretical model of knowledge substitutability and knowledge complementarity affecting the number of new product development.Taking 574 vehicle production firms in the eastern,central and western parts of China as our research samples,then using Stata to test the relevant hypothesis and empirical analysis.The results show that:①Knowledge substitutability has a positive effect on the number of new product development,while there is an inverted U-shape between knowledge complementarity and the number of new product development.②Moreover,technological diversity plays a positive moderating role between knowledge substitutability and the number of new product development,but its moderating effect between knowledge complementarity and the number of new product development is not remarkable.③While the intellectual property protection plays a positive moderating effect on the effect of knowledge substitutability and the number of new product development,and its moderating effect on the effect of knowledge complementarity and the number of new product development is supported.The results reveal that knowledge substitutability and complementarity
