Occasional and Persistent Innovators in Poland: An Empirical Study of Obstacles to Innovation and Their Complementarities
Occasional and Persistent Innovators in Poland: An Empirical Study of Obstacles to Innovation and Their Complementarities

Summary/Abstract: This paper investigates barriers to innovation perceived by innovating firms and complementarities between such barriers. The study analyses two periods: 2002-2004 and 2004-2006, covered by two Community Innovations Surveys (CIS): CIS4 and CIS5, respectively. We distinguish two groups of innovating firms - those which introduced innovations in either CIS4 or CIS5. We label the former group peristent innovators, and the latter - occasional innovators. We use a multivariate (factor and cluster) analysis covering binary correlations, Principal Component Analysis, probit model and correlations of disturnbances. Two types of explanatory variables describing firms' characteristics and innovation inputs used are considered. The paper shows that there are considerable differences in sensitivities to the perception of innovation barriers and in complementarities among barriers between persistent and occasional innovators. In the case of occasional innovators, a kind of innovation barrier chain is observed. This has an impact on differences in the frequency of innovatio activities between the two groups of innovators and results in diversification of innovators.
