The subject of the paper is to investigate the hypothetical perceptions of the impact of negative externalities on the expansion and development of selected Adriatic seaports. The aim of the paper is to show that Adriatic seaports must accept and apply the integration strategy as a key business and logistic competence, which can be the basis for their expansion and development. Therefore, this paper starts with the basic hypothesis that a partner business performance and cooperation between the Adriatic seaports of Koper, Rijeka, and Bar is a crucial condition for easier finding of large foreign investors and global logistics providers. It also starts with the auxiliary hypothesis that it is necessary to overcome many business barriers, which are treated as negative externalities. For researching the perception of the impact of negative externalities, the multiple linear regression method is used. It is concluded that the level of selected negative externalities is different in individual selected ports, but also between them. The research results verified the initial hypothesis.
