The formation of the harmony of the maritime trade market is based on the reaction of ship-owning and port structures to the nature of changes in the main characteristics of cargo flows. At the same time, relations and the reaction of the ship-owning complexes to the optimization of the technical and economic level of the competitors are being formed. A shipping company as an enterprise develops and functions in contrast to other production structures of the national economy in the context of international competition. Regardless of the flag of registration of ships, companies operate in the global maritime trade market. It is the priorities of international conventions that determine managerial and marketing technologies. Therefore, a special nature of the participation of shipping companies in the formation of the final economic results is formed. It is this factor that requires constant clarification of the patterns of sustainable positionning in the system of the international division of labor. Also, it should be noted that the most important tendencies in improving the management of the development of subsystems of the national maritime transport industry are balancing the assessment of the merchant fleet and ports both from the standpoint of macroeconomic and entrepreneurial interests. Therefore, research focuses on the selection andimplementation of the special priorities of the national maritime transport complex. In this regard, the temporal characteristics of the routes are considered rather thoroughly. However, the inconsistency of approaches to the formation of systemic security remains.The efficiency of the state and functional and economic stability should be consi-dered as the main criterion for changing the form of the ownership. With the stability and sustainability of maintaining the liquidity conditions of the enterprise, the change of ow-nership is determined by market conditions and the marketing strategy of the owner himself. Usually, in this state, the change in the form of ownership on the part of the owner has particular number of non-standard reasons. For such enterprises, privatization is problematic because it does not optimize the social and economic con-sequences and results.Keywords: maritime trade, shipping companies, cargo flows, marketing techno-logies.
