Small and medium sized enterprises (SMEs) constitute a major part of the economies of both developed and developing countries. SMEs play a very important role in the Turkish economy as well. They make up 91.9 percent of all enterprises, represent 78 percent of all employment and constitute 55 percent of GDP and 50 percent of total investment. Definitely, supporting the SMEs can provide a sustainable and balanced economic growth. Their integral role within an economy has become a source of inspiration for several academicians to study SMEs from different perspectives. This paper aims to categorize and summarize these studies. The fields of categorization are "Economic Growth, Finance and Risk, Management, Innovation, Supports, Industries and Globalization and Internationalization".
