In this study; Turkey's economic transformation between 1970 and 2012 was examined by means of an input-output model. The economy was divided into 10 sectors in the analysis to maintain consistency over all historical input-output tables. As a result of the analysis, the sector with the highest forward and backward linkage effects has been identified as intermediate goods producing industries. The analysis shows that Turkey's economy has transformed to an industry-based economy from agriculture-based economy. However, it is clear that economic transformation should continue for a more developed economy. In particular, products with high added value need to be focused in production.
