Cross-border cooperation is becoming an increasingly important factor in establishing a stimulating business environment. The aim of the article is to introduce factors that influence cross-border cooperation between businesses in the Alps–Adriatic region. A
descriptive and analytical approach is used. On the basis of the results of empirical international research into cross-border cooperation in the Alps–Adriatic region between Carinthia, Friuli-Venezia Giulia (FVG) and Slovenia the article shows and analyses the barriers that businesses face in cross-border cooperation and the factors they consider to best stimulate cross-border cooperation. The results show that good personal relations, language skills and shared interests are the most important factors; the level of assistance and administrative/legislative barriers are the biggest barriers in cross-border cooperation. Different factors stimulating cross-border cooperation can be used to create a base for future strategies and training for business managers
