Industrialization from the interindustries perspective is to make stronger the structural connections between the industries, also to improve lack of connections between industries and to lessen the dependencies on other foreign economies. In the development strategies, to reach the purpose and the goal, what kind of information and criterion are chosen for the sectoral decisions? The answers given for these questions bring us to the concept of leading sectors. The economic usages of scarce resources and the consistency between the sectors can be provided when the precedence has been given to the leading sectors. The process opened to membership of the European Union through the membership of Customs Union may provide some advantages for industrial sector in Turkey. The market entering facilities, easy access to foreign capital and rising standart of competition may increase the efficiency by the way of providing effective usage of resources directed to the industrial sector. In case of Turkey's accession to the European Union and direction of the foreign capital to the industrial sector, especially to the leading sectors, the developmentoftheeconomywillgetfaster. Certainly,providingprecedence to the investment in the leading sectors is the basic economic principle to be obeyed, not only because of foreign competition but also of causing of producing more value added and getting more output per capita investment.
