Direct investments, cooperation links, information flows, global infrastructure, as well as agglomeration effect, fill up the space with geo-economic content. In this paper, a classification of the main territorial elements of globalized geo-economic space (GGS) was done. In that way, we especially mark out the ports and port-cities. However, if the role of these ' hotbeds ' of economic activity is estimated very clearly in the view of global economic agents (the speed of operation, the presence of a full-service, single-window effect, cost and time savings, additional markets and new resources), but contribution of this elements to the home economy of a particular country or region and its connectivity with hinterland are the subject of a certain study. Thus, based on spesial literature and statistical data the different types of the major elements of GGS of the USA., Western Europe, China were formulated, also its competitivness, impacts to the development of home economy were evaluated. In our work, we emphasize that the effect of the proximity to such centers sometimes goes far enough beyond their formal boundaries and has a decisive influence on the development of a space at different levels. There is a vivid example of Dongguan (China), located in Guangdong Province. Thanks to the neighborhood of Hong Kong - world city of alpha-group (according to Peter J. Taylor, World city network: a global urban analysis. Routledge 2004), this city took the leading position in the world for the production of electronic products, its population has exceeded 7 million people, an average annual GDP growth from 1980-2005 was 22%. So, economic and geographical approach to this problem most fully reflects the whole range of economic relationships between territories. On the other hand, a high traffic, economic, tourist activity also leads to the creation of specific issues for their respective regions, especially environmental. These problems, in that point of view, are inside and solved through regions' own resources. Therefore, in the paper we also studied administrative management features of separate elements, which meet with modern environmental standards and their requirements for the participants of value-added chains. The study of foreign experience elements of geo-economic space allows us to make some analogies and draw conclusions about the prospects for the development of Ust-Luga port in St.-Petersburg coastal region as a global importance contact zone and growth poles of the national economy.
