Corporations across the world are highly interconnected in a large global network of corporate control. This paper investigates the global board interlock network, covering 400,000 firms linked through 1,700,000 edges representing shared directors between these firms. The main focus is on the concept of centrality, which is used to investigate the embeddedness of firms from a particular country within the global network. The study results in three contributions. First, to the best of our knowledge for the first time we can investigate the topology as well as the concept of centrality in corporate networks at a global scale, allowing for the largest cross-country comparison ever done in interlocking directorates literature. We demonstrate, among other things, extremely similar network topologies, yet large differences between countries when it comes to the relation between economic prominence indicators and firm centrality. Second, we introduce two new metrics that are specifically suitable for comparing the centrality ranking of a partition to that of the full network. Using the notion of centrality persistence we propose to measure the persistence of a partition’s centrality ranking in the full network. In the board interlock network, it allows us to assess the extent to which the footprint of a national network is still present within the global network. Next, the measure of centrality ranking dominance tells us whether a partition (country) is more dominant at the top or the bottom of the centrality ranking of the full (global) network. Finally, comparing these two new measures of persistence and dominance between different countries allows us to classify these countries based the their embeddedness, measured using the relation between the centrality of a country’s firms on the national and the global scale of the board interlock network.
In this paper we address a number of these issues, as we consider the largest @math million firms across the globe, allowing us to compare results with sufficient data in each country. The causal effects remain beyond the scope of this work, as we are foremost interested in understanding centrality at and between different national and global scales of the global corporate network network. Our work differs from studies such as @cite_19 in a sense that we still want to take the connectedness of the nodes within a particular partition of the full network into account, rather than merging all of the subset's nodes into one. To the best of our knowledge, this work is the first study in which the global corporate network is analyzed at such a large scale, particularly in the context of centrality, investigating the embeddedness of countries in the global network of corporate control.

We investigate the community structure of the global ownership network of transnational corporations. We find a pronounced organization in communities that cannot be explained by randomness. Despite the global character of this network, communities reflect first of all the geographical location of firms, while the industrial sector plays only a marginal role. We also analyze the network in which the nodes are the communities and the links are obtained by aggregating the links among firms belonging to pairs of communities. We analyze the network centrality of the top 50 communities and we provide the first quantitative assessment of the financial sector role in connecting the global economy. The structure of the control network of transnational corporations affects global market competition and financial stability. So far, only small national samples were studied and there was no appropriate methodology to assess control globally. We present the first investigation of the architecture of the international ownership network, along with the computation of the control held by each global player. We find that transnational corporations form a giant bow-tie structure and that a large portion of control flows to a small tightly-knit core of financial institutions. This core can be seen as an economic “super-entity” that raises new important issues both for researchers and policy makers. 0 Introduction.- I Themes and Problems.- 1.0 Introduction.- 1.1 The theory of finance capital.- 1.2 Interlocking directorates and economic power.- 1.3 Financial groups.- 1.4 Corporate elite and capitalist class.- 1.5 Summary.- II Between Market and Hierarchy.- 2.0 Introduction.- 2.1 The organization of firms and markets: a neo-classical explanation.- 2.2 Some definitions of firms.- 2.3 Power and control.- 2.4 Ownership and control.- 2.5 Competition, cooperation and control.- 2.5.1 Concentration and centralization.- 2.5.2 The level-of-analysis problem.- 2.6 Summary.- III Imperialism in the Seventies: two models.- 3.0 Introduction.- 3.1 Theories of imperialism.- 3.1.1 Their origins.- 3.1.2 After World War II.- 3.2 Two models.- 3.3 Research design.- 3.4 Summary.- IV The International Corporate Elite.- 4.0 Introduction.- 4.1 The organization of the supervising and executive function in different countries.- 4.2 Selection of the international corporate elite.- 4.3 Network characteristics of the international corporate elite.- 4.3.0 Introduction.- 4.3.1 The finance capitalists.- 4.3.2 The big linkers.- 4.4 Types of interlocking directorates.- 4.4.0 Introduction.- 4.4.1 Multiple interlocks.- 4.5 Summary.- V National Versus International Integration.- 5.0 Introduction to some graph-theoretical concepts.- 5.1 General patterns in the international network.- 5.1.1 Compactness of the international network.- 5.1.2 International integration of national networks.- 5.2 The international network of Western firms.- 5.2.0 Introduction.- 5.2.1 Local centrality.- 5.2.2 Global centrality.- 5.2.3 Overall centrality.- 5.3 Industrial concentration versus economic centralization.- 5.4 Summary.- VI Domination and Control.- 6.0 Introduction.- 6.1 Clusters of heavily interlocked firms.- 6.1.1 The network at multiplicity-level two.- 6.1.2 The network at multiplicity-level three.- 6.1.3 Conclusions.- 6.2 The network of officer-interlocks.- 6.2.0 Introduction.- 6.2.1 Domination and control.- 6.2.1.1 The network of all officer-interlocks.- 6.2.1.2 The network of control.- 6.2.2 Financial groups.- 6.2.3 Constellations of interests.- 6.3 Summary.- VII Competition and Cooperation: the role of banks.- 7.0 Introduction.- 7.1 Interlocks among banks.- 7.2 Overlapping spheres of interests.- 7.3 International bank consortia.- 7.4 The American banks.- 7.5 Summary.- VIII The Impact of World Crisis: changes in the network.- 8.0 Introduction.- 8.1 A new economic world order?.- 8.2 Selection of the 1976 sample.- 8.3 The international corporate elite.- 8.3.1 Finance capitalists.- 8.3.2 Big linkers.- 8.4 International versus national integration.- 8.5 Centrality in the nested networks (1976).- 8.6 Domination and control in the 1976 network.- 8.7 Summary.- IX Summary and Conclusions.- 9.1 Introduction.- 9.2 The structure of the international corporate elite.- 9.3 Conflict or cooperation.- 9.4 The meaning of interlocking directorates.- 9.5 The international corporate elite.- References.- Authors Index.- Firms Index.- Appendix A. Abstract As network analysis methods prevail, more metrics are applied to co-word networks to reveal hot topics in a field. However, few studies have examined the relationships among these metrics. To bridge this gap, this study explores the relationships among different ranking metrics, including one frequency-based and six network-based metrics, in order to understand the impact of network structural features on ranking themes on co-word networks. We collected bibliographic data from three disciplines from Web of Science (WoS), and generated 40 simulation networks following the preferential attachment assumption. Correlation analysis on the empirical and simulated networks shows strong relationships among the metrics. Their relationships are consistent across disciplines. The metrics can be categorized into three groups according to the strength of their correlations, where Degree Centrality, H-index, and Coreness are in one group, Betweenness Centrality, Clustering Coefficient, and frequency in another, and Weighted PageRank by itself. Regression analysis on the simulation networks reveals that network topology properties, such as connectivity, sparsity, and aggregation, influence the relationships among selected metrics. In addition, when comparing the top keywords ranked by the metrics in the three disciplines, we found the metrics exhibit different discriminative capacity. Coreness and H-index may be better suited for categorizing keywords rather than ranking keywords. Findings from this study contribute to a better understanding of the relationships among different metrics and provide guidance for using them effectively in different contexts.
