Properties of knowledge base and firm survival: Evidence from a sample of French manufacturing firms

• We analyze the effects of knowledge structure on the survival likelihood of firms.
• Technological knowledge is modeled as an outcome of a recombinant activity.
• We derive indexes able to feature exploration and exploitation search patterns.
• Exploitation search strategies are associated to higher chances to survive.

The paper analyzes the effects of the properties of firms' knowledge base on the survival likelihood of firms. Drawing upon the analysis of the patterns of co-occurrence of technological classes in patent applications, we derive the coherence, variety and cognitive distance indexes, accounting respectively for technological complementarity, differentiation and dissimilarity in the firms' patent portfolios. The results of our analysis are in line with the previous literature, showing that innovation enhances the survival likelihood of firms. In addition, we show that the search strategies at work in the development of firms' knowledge base matter in reducing the likelihood of a failure event. Knowledge coherence and variety appear to be positively related to firms' survival, while cognitive distance exerts a negative effect. We conclude that firms able to exploit the accumulated technological competences have more chances to be successful in competing durably in the market arena, and derive some policy implications concerning the role of public intervention in the orientation of search efforts in local contexts.
