This study investigates and compares regulations in the distribution sector of OECD. It is noteworthy that the regulations of OECD distribution sector show contradiction. Through regulatory reforms in many European countries the regulations are to a greater extent becoming liberalized especially in such areas as market access, price control, and service regulations. On the contrary some major European nations in line with liberalization in the distribution sectors change their lines and tend to restrict large-scale retail stores. In the extreme cases regulations in the distribution sector often play obstacles to market access due to unnecessary limited regulations and excessive governmental burdens.
