HRM and product innovation: does innovative work behaviour mediate that relationship?

Abstract

PurposeThe purpose of this paper is to empirically analyse the mediator effect of innovative work behaviour (IWB) between the firm’s human resource management system and product innovation.Design/methodology/approachData are collected from 225 Spanish manufacture companies. Hypotheses are tested using structured equation modelling. The structural model is estimated through partial least squares modelling.FindingsThe results provide strong evidence about the effect of the system of human resource management practices on both, employee’s IWB and product innovation. Furthermore, findings support the idea that employee’s IWB mediates the relationship between human resource management and product innovation.Research limitations/implicationsAlthough the study counts with the limitations of cross-sectional studies, its findings suggest that employees’ IWB fosters product innovation and that the adoption of a high-performance work system is positively associated to such behaviour.Practical implicationsThis paper shows that companies seeking to foster product innovation should pay attention to their employees’ behaviour. In particular, they should promote that employees engage in innovative behaviours, and that adopting high-performance human resource management practices can help in this line.Originality/valueAlthough a number of studies suggest that IWB is a key determinant of innovation and a mediator in the link between human resource management and innovation, there is no empirical research examining these relationships. This paper covers this gap detected in the literature and provides evidence supporting them.
