Introduction of an objective model to measure open innovation and its application to the information technology convergence sector

Abstract

This study attempts to develop a new objective method to measure open innovation. It proposes a new concept for measuring open innovation using patent information to improve on the ideas of the 'width' and 'depth' dimensions of open innovation. Based on the review of related literature, three open innovation measures are proposed: Ratio of Open Innovation (ROI), Intensity of Open Innovation (IOI) and Total Level of Open Innovation (TOI). These measures are applied to compare open innovation levels between nations and between firms as well as to analyse the effect of open innovation on firm performance.
