We study the relationship between a patent‐based measure of knowledge spillovers that calculates technological proximity based on technologically relevant firms and innovation success. We find – for a representative sample of Swiss firms – that knowledge spillovers have a positive and significant association with the commercial success of innovative products. The paper shows the importance of market conditions for the relationship of spillovers with innovation performance: It is only positive and significant in markets with a medium number of competitors in the main product market, but not in monopolistic or polypolistic market structures.

知识溢出、竞争和创新成功

我们研究了基于专利的知识溢出衡量标准（该衡量标准基于技术相关公司计算技术接近度）与创新成功之间的关系。我们发现——对于瑞士公司的代表性样本——知识溢出与创新产品的商业成功有着积极而重要的关联。本文展示了市场条件对溢出与创新绩效关系的重要性：它仅在主要产品市场中具有中等数量竞争者的市场中是积极的和显着的，而不是在垄断或垄断市场结构中。
