摘要:This scientific study focuses on the economic and especially the psychosocial factors of success in negotiation processes between buyers (procurers) and suppliers (producers) in the food trade. In particular, it examines the economic and mental satisfaction in the decision-making and in the negotiation processes for efficient food supply. It studies primarily transparency in addition to the Harvard concept at annual meetings (or during the year) favoring a satisfactory result for both negotiators. In a structural equation model, the Harvard negotiating points are brought together with transparency in communication, in terms of successful economic experiences and socio-mental satisfaction.
