Description
Summary:PurposeThis study focuses on resolving empirical inconsistencies in the relationship between external search breadth and innovation performance. Based on research on the knowledge-based view and innovation barriers, three internal barriers that weaken the effectiveness of external search breadth are discerned: information, rigidity and financial barriers.Design/methodology/approachFor empirical analysis, the Korean Innovation Survey 2016 of manufacturing firms was utilized. This study defines innovation performance as the number of patent applications and new product introduction that are analyzed through zero-inflated negative binomial and logistic regressions, respectively.FindingsThe empirical analysis showed three findings. First, external search breadth has a positive relationship with the number of patent applications but not with new product introduction. Second, financial barrier weakens the positive association of external search breadth with the number of patent applications. Third, the interactions of external search breadth with the three internal barriers are negatively related to new product introduction.Originality/valueThis study makes two theoretical contributions. First, by examining barriers to external knowledge search, this research helps identify potential bottlenecks in this search. Second, the study reveals that the effectiveness of external search breadth may have a boundary in firm innovation by showing that this search affects patent application and new product introduction differently.
