There is a dearth of empirical research on the impact of external knowledge search on innovation performance in different categories of service firms. This study explores the effectiveness of the breadth of external search on product and process innovations in German firms. In particular, we model a non-linear relationship between the breadth of knowledge and product and process innovations. Drawing on the Mannheim Innovation Panel (MIP) data for the German service firms in the period 2014-2016, we report findings from a bivariate probit model, which takes into account mutual interdependence between product and process innovations. Moreover, the model is separately estimated for knowledge-intensive business services (KIBS) and other services. For comparative purposes, we also estimate the model for manufacturing firms. Empirical findings uniformly show an inverted U-shaped effect of the breadth of knowledge on both product and process innovations. Furthermore, the results demonstrate that using up to three knowledge sources increases the probability of a joint implementation of product and process innovations. These findings hold for both KIBS firms and other services. However, those service firms that focus on a single type of innovation experience diminishing returns to external knowledge when exploiting more than one source of knowledge. These results suggest that a simultaneous introduction of different types of innovation requires diverse knowledge sources. In contrast, when focusing on a single type of innovation, service firms experience diminishing returns when using multiple sources. However, this finding is only partially found for manufacturing firms. Accordingly, our findings provide support for the demarcation approach, insofar as the breadth of knowledge has a heterogenous impact on innovation in manufacturing relative to service firms. Previous studies on the breadth of knowledge search mostly examined its influence on innovation performance without separately analysing manufacturing and service firms. The present study focuses on service firms, that are further divided into KIBS and other service firms. By investigating potentially non-linear relationships between knowledge breadth and product and process innovations, it illustrates how different innovation strategies are affected by a diverse pool of external knowledge sources.

服务业外部知识搜索的广度

缺乏关于外部知识搜索对不同类别服务公司中创新绩效影响的经验研究。这项研究探讨了外部搜索对德国公司产品和流程创新的影响。特别是,我们对知识的广度与产品和过程创新之间的非线性关系进行建模。利用2014-2016年间德国服务公司的曼海姆创新小组(MIP)数据,我们报告了一个双变量概率模型的发现,该模型考虑了产品和流程创新之间的相互依赖性。此外,该模型是针对知识密集型业务服务(KIBS)和其他服务分别估算的。为了进行比较,我们还估计了制造公司的模型。经验发现一致地表明,知识广度对产品和工艺创新的倒U型影响。此外,结果表明,最多使用三个知识源会增加联合实施产品和流程创新的可能性。这些发现对KIBS公司和其他服务公司都适用。但是,那些专注于单一类型创新的服务公司在利用多种知识来源时会减少对外部知识的回报。这些结果表明,同时引入不同类型的创新需要多种知识资源。相比之下,当专注于单一类型的创新时,服务公司在使用多种来源时会遇到收益递减的情况。但是,这一发现仅部分针对制造公司。因此,我们的发现为分界方法提供了支持,因为知识的广度对制造业相对于服务公司的创新具有异质的影响。先前关于知识搜索范围的研究大多检查了其对创新绩效的影响,而没有分别分析制造和服务公司。本研究的重点是服务公司,进一步分为KIBS和其他服务公司。通过研究知识广度与产品和过程创新之间潜在的非线性关系,它说明了不同的创新策略如何受到多种外部知识资源的影响。相对于服务公司,知识的广度对制造业的创新产生异质影响。先前关于知识搜索范围的研究大多检查了其对创新绩效的影响,而没有分别分析制造和服务公司。本研究的重点是服务公司,进一步分为KIBS和其他服务公司。通过研究知识广度与产品和过程创新之间潜在的非线性关系,它说明了不同的创新策略如何受到多种外部知识资源的影响。相对于服务公司,知识的广度对制造业的创新产生异质影响。先前有关知识搜索广度的研究大多检查了其对创新绩效的影响,而没有分别分析制造和服务公司。本研究的重点是服务公司,进一步分为KIBS和其他服务公司。通过研究知识广度与产品和流程创新之间潜在的非线性关系,它说明了不同的外部知识源如何影响不同的创新策略。本研究的重点是服务公司,进一步分为KIBS和其他服务公司。通过研究知识广度与产品和流程创新之间潜在的非线性关系,它说明了不同的外部知识源如何影响不同的创新策略。本研究的重点是服务公司,进一步分为KIBS和其他服务公司。通过研究知识广度与产品和流程创新之间潜在的非线性关系,它说明了不同的外部知识源如何影响不同的创新策略。
