Rusak D. The Development of Global Corporate Networks in the Geo-economic Transformations Environment .

The dissertation defines the essence, structure, and core components of global corporate networks (GCNs), elaborates the concept of prominent role of such networks in the structure of world economy and international economic relations as the aggregate of value, production, innovation, corporate and other chains. The essence, structure, and systemic characteristics of the genesis of GCNs development have been established on the basis of the elaboration and comprehensive application of the neoclassical and neo-institutional paradigms. The author expounds the impact of GCNs on the restructuring of the modern geo-economic space leading to the formation of new centers in the shape of global cities. The system of influence of inter-organizational and inter-fragment external and internal relations in the network economic systems in the form of GCNs has been identified, and the correlation between diffusion of network MNEs ownership and its influence on the formation of the GCNs meta-network has been established. The dissertation defines the theoretical and methodological tenets of cluster analysis of global corporate networks. Based on the multi-criterion clustering of 64 countries using the k-means, the research has verified the existence of five sustainable participation models in the global corporate networks that vary in terms of the development level of a country, scale of its local stock market maturity, the quantity of outbound and inbound corporate connections, and geography. The mechanism of engaging the Ukrainian economic entities into the global corporate networks of micro- and meso-levels has been elaborated given the implementation of appropriate administrative and institutional reforms. Based on the convergence model devised in the thesis, an algorithm has been developed for the interaction between the national cluster and MNEs, and its further integration into GCNs. It consists in creating institutional prerequisites for introducing changes in the work of the State Agency of Uraine for Exclusion Zone Management and improvement of management. The innovative and competitive issues have been determined where the state must galvanize within the framework of the desined model for integrating the national R&D cluster into GCNs. Among these, as regards shaping the inter-fragment ties, most promising MNEs will be those already integrated into GCNs and with available structural nodes of corporations working in such areas as nuclear energy research (materials, matter), space technologies, radiation safety, and technologies.
