Reduced opportunities for regional renewal: The role of rigid threat responses among a region's established firms

This article illustrates how opportunities for regional renewal in a peripheral region may be reduced by rigid threat responses undertaken by established firms operating within traditional regional industry. In an inductive case study of new biorefinery industry initiatives in a region where traditional pulp-and-paper and forestry industry was in decline, we used primary and secondary data to outline how a set of new industry players who created innovative ways of using existing regional infrastructures and resources sparked rigid threat responses among established firms from the struggling traditional industry. Established industry firms framed new industry initiatives as threats, and responded by (1) reducing new industry actors’ possibilities for new business development, (2) engaging in entrenched resistance, (3) creating collaborative illusions and (4) undermining the fundamentals of the new industry. Consequently, this study contributes to existing literature by proposing the potential of applying the threat-rigidity thesis on a regional level. This is achieved by illustrating that conflicting behaviours between new and established regional industry actors constrain opportunities for regional renewal in a peripheral region. As such, relevant directions for future research and policy implications are outlined.
