How has regional planning been transformed in increasingly changing socio-economic and political contexts in transition economies? Why do regional planning policies and practices change? This paper explains how the policy ideas of regional development have been formulated and incorporated into the Turkish context since the establishment of modern-day Turkey in 1923. The transformation process shows how, in one way or another, policy ideas have been brought into or appeared in Turkey to shape regional policy. It emphasizes that this sort of acquisition of thinking has been translated into policy frameworks. In other words, Turkey has been taking on policies that have been devised using ideas from outside Turkey which are being dominated by growth-oriented strategies that represent a neoliberal political agenda.
