Does intellectual capital allow improving innovation performance? A quantitative analysis in the SME context

Purpose The purpose of this paper is to investigate the association between the strength of intellectual capital (IC) and small- and medium-sized enterprise (SME) innovation performance. Design/methodology/approach Primary data of 150 SMEs belonging to manufacturing medium-high tech industries were collected through a survey. The methodology consists of a confirmatory factor analysis and a cluster analysis, complemented by a t -test, to assess whether there is a significant difference in terms of innovation performance of SMEs characterized by a different strength of IC. Findings Overall, the findings show that SMEs of the sample can be divided into two groups characterized by a different strength of IC, and those SMEs disclosing a higher strength of IC, in terms of human capital, innovation capital and relational capital, exhibit a significantly higher radical and incremental innovation performance. Practical implications The present study provides SME entrepreneurs and managers with an empirical evidence that possessing strong IC in its three dimensions seems to help SMEs reinforce their ability to generate both radical and incremental innovation. This calls that SME entrepreneurs and managers need to identify and effectively manage IC in order to strengthen and effectively leverage their investments on IC. Originality/value This study is particularly relevant because, instead of focusing on single categories of IC as previous studies mainly do, it adopts an overarching perspective of the dimensions of IC and their impact on both radical and incremental innovation performance. Moreover, it focuses on the SME context which has been less investigated than large firms within the domain of IC.
