Abstract

This paper discusses some game-theoretical methods for measuring indirect control in complex corporate shareholding networks. The methods use power indices in order to estimate the direct and indirect control in shareholding structures. Some of these methods only estimate the control power of investors (firms without shareholdings), and only a few measure the control power of all firms involved in shareholding networks (which means investors and stock companies). None of them take measuring the importance of mutual connections (edges in the networks) into consideration; thus we focus in particular on an extension of these methods in this paper in order to measure both the control-power of the firms involved in complex shareholding structures (represented by nodes in networks), and the importance (power) of linkages between the firms as elements of a whole corporate shareholding network. More precisely, we apply our approaches to a theoretical example of a corporate network. Moreover, we continue the considerations started in Mercik and Stach (Transactions on Computational Collective Intelligence XXXI, LNCS 11290: 64–79, 2018) about reasonable properties for indirect control measurement. Some ideas of new properties are proposed. The paper also provides a brief review of the literature concerning the topic.
企业网络中控制权的测量
本文讨论了复杂公司股权网络中间接控制测度的一些博弈论方法。该方法利用权力指数来估计股权结构中的直接和间接控制。其中一些方法只估计投资者(没有持股的公司)的控制权,只有少数方法衡量所有参与股权网络的公司(即投资者和股票公司)的控制权。它们都没有考虑到测量相互连接(网络中的边)的重要性;因此,我们在本文中特别关注这些方法的扩展,以衡量参与复杂股权结构(由网络中的节点表示)的公司的控制权,以及作为整个公司股权网络要素的公司之间联系的重要性(权力)。更准确地说,我们将我们的方法应用于一个公司网络的理论例子。此外,我们继续在Mercik和Stach (Transactions on Computational Collective Intelligence XXXI, LNCS 11290: 64 - 79,2018)中开始的关于间接控制测量的合理性质的考虑。提出了一些新性质的设想。本文还简要回顾了有关该主题的文献。
