Transformation of large agribusiness corporations in Serbia is at its beginning. Institutional investors are taking control of these firms through foreign direct investments. Corporate reorganization of agribusinesses starts up by introducing efficient management, information technology, Net and e-commerce. IT environment generates a new business model, which creates connections in Serbia between the large agribusinesses, business processes and IT. The market of agricultural production in Serbia is rapidly changing and adapting itself to the global trends, mainly to the Internet economy. The speed of transactions and volume of information is increasing dramatically. It is important to explain the basic economic principles at macro and micro levels. Such revolutionary changes affect the operations and management of agribusiness on the Internet and outside of it. The purpose of this work is to stimulate further research in these processes, and to use the acquired knowledge as a tool for efficient corporate agribusiness management.
