Abstract :Development of products exports causes the markets to get closer to competitive situation and domestic producers to be able to use their production capacity as much as possible. For this purpose, innovations, inventions and creativities of the labor force will be useful during the production and export process. In fact, investing in human capital causes its abilities to be developed so that the more educated and skilled they are, the easier and more accurate it will be for them to learn sophisticated things and it increases the level of their skill and abilities. Therefore, using skills and professions of skilled and creative manpower during the exports of different products process, not only results more productive use of domestic sources, attraction of foreign advanced technology and creation of technology for producing new products, but also it creates new ways to use production factors or raw material and by that, it can cause increase of exports and achieving economic growth in countries. Considering this, the purpose of this study is to analyse the factors affecting exports emphasising on human capital in 20 selected developing countries in period of 1995 to 2014 using panel data model. The results of the estimation show that human capital has positive and meaningful effect on exports of the studied countries in the considered period. Also variables of active population, capital formation and healthcare costs also have had positive and meaningful effect on exports.
