At the present stage, the knowledge-intensive services sector is one of the key drivers of the global knowledge-based economy. Knowledge-intensive services cover a wide range of market, financial, high-tech, social and other services based on the knowledge and experience of highly qualified specialists. This type of services acts as a catalyst for innovation activities of organizations based on an organic combination of production processes, research and development activities and consumer needs. Based on the study of a wide range of literary sources on the problems of innovation, innovation activities, knowledge-intensive services the concept of "knowledge-intensive services" was clarified, under which it is proposed to understand a wide range of services that are based on the knowledge of highly qualified professionals and acting as a catalyst for innovation activities of organizations based on an organic combination of production, science and consumers. The results of the analysis of foreign and domestic trends in the export of knowledge-intensive services allow to assert that Ukraine has a significant human resource potential, the implementation of which can provide high volumes of provision of knowledge-intensive services. The positive dynamics of development of knowledge-intensive services export by Ukraine indicates that our country has real prospects to become a successful innovation region in the near future. After all, it has been proven that one of the key catalysts of innovation activity is the services that are based on the knowledge of highly qualified specialists and allow to combine production processes, scientific activity and consumer needs. Thanks to the opportunity to increase exports of knowledge-intensive services, there will be a chance to expand the shares of foreign markets and thus ensure the progressive development of the national economy.

This task should be implemented at all levels of the national economy, which will allow obtaining a synergistic effect in this area. Thus, the level model of development of export of knowledge-intensive services as a catalyst for innovation activity was improved. The proposed model organically combines and systematizes the priority objectives of development of the export of knowledge-intensive services, key stakeholders to be involved in the development of export of knowledge-intensive services in Ukraine, the priority ways, vectors and tools of development of the export of knowledge-intensive services, as well as the expected results of the impact of development of export of knowledge-intensive services at the macro-, meso- and micro-levels of the national economy. In addition, the level model of development of export of knowledge-intensive services as a catalyst for innovation activity represents the mechanism of relationships between all structural elements, which allows to achieve a synergistic effect in the development of export of knowledge-intensive services of Ukraine.
