7. Discussion and conclusion
Our research synthesis of a variety of cluster SMEs’ international competitive strategies and their outcomes offers theoretical and practical contributions.
7.1. Theoretical contribution
This paper expands the literature on the internationalisation of SMEs, with a focus on cluster SMEs. It contributes by synthesising and evaluating a comprehensive range of SME-strategic options and by proposing the proactive competitive strategies of SMEs in the international arena that are both feasible and effective. The extant studies in SME internationalisation focus on the conditions and drivers of internationalisation rather than on the outcomes of specific strategies (Carr et al., 2010; Hilmersson, 2014; Tang, 2011). Therefore, this paper addresses the research gap of the evaluation of SME-strategic options in internationalisation. In the area of cluster SME internationalisation, recent studies analysed some selected strategic options (Mariotti, Micucci & Montanaro, 2004; Biggiero, 2006; De Propris et al., 2008; Mariotti, Mutinelli & Piscitello; 2003; Cutrini, 2011). This study responds to the call for a systematic analysis and synthesis of the extant research evidence.
