This paper explores the relation between capital accumulation and transformation of industrial structure in a small open-economy. Using a three-sector, neoclassical growth model with non-homothetic preferences, we examine dynamic behavior of the small country in the alternative trade regimes. We show that capital accumulation plays a leading role in the process of structural transformation. It is also revealed that the trade pattern significantly affects structural change. We demonstrate that our model can mimic a typical pattern of change in industrial structure that has been observed in many developed economies.
