The article presents a model that will allow substantiating the sequence of introducing a system of innovative activities with integrated management of an integrated model of innovative activity. In order to identify the sequence of innovative activities, a study was made of indicators of maritime trade in Ukraine for the period from 2016 to 2020 according to the State Statistics Service of Ukraine. The features of the formation of an innovative marketing plan in the integrated model of innovative activity in maritime trade are considered. Using the presented mathematical model, an analysis of a potential plan for the introduction of innovations in various fields was carried out on the example of maritime trade in Ukraine, and their sequence was determined. The proposed mathematical model can be used to identify the influence of a certain set of factors on the result. The model can be applied to various types and categories of activities, showing the degree of influence of each of the selected influencing factors on the selected resulting attribute. The ability to select an arbitrary number of influence factors makes it universal for use in different types of activities and at different stages of analytical work. The article provides an example of the application of the developed mathematical model for the maritime trade of Ukraine. The obtained results indicate that the priority task in the field of innovation is the modernization of liquid transportation (significance coefficient for the final result -0.09), container transportation (significance coefficient -0.03), and packaged cargo (significance coefficient 0). Conducting a study in the field of maritime trade is due to the increase in the level of importance of this type of trade in modern conditions
