We revised the concept and its explanation, and added some references in Section 2.2 and in Introduction. For more details, please see below.
the conceptual framework appears simplistic, technocratic and static, and it is not sufficiently rooted in literature as evident from the scarcity of references in section 2.2. It is simplistic and technocratic because it views cluster performance as an outcome of initial conditions (i.e., the state of cluster development), cluster management and national polices. The paper thus rests on the untested presumption that cluster management and national policies actually impact the performance of clusters. As scholars, the authors should challenge this technocratic faith of policy-makers and practitioners, although evaluation is beyond this paper’s scope.
