The main aim of this paper is to reveal if development and current state of the Turkish Economy are sustainable. Instead of the research tools offered in environmental economics, the holistic approach of ecological economics is used to answer this question. Within that context, the Turkish Economy is assessed within the concept of steady-state economics. Having assessed the data related to the three institutional changes suggested within the concept, this study shows the obstacles and advantages of the Turkish Economy to move towards the steady-state, in other words, sustainability.
