本文首先通过图论对所要研究的非交叉持股金字塔股权结构进行定义,然后用一实例将最弱环节法和矩阵合并法对行对比,结果发现最简单的操作模型是最弱环节模型,但该模式并不能准确识别公司的真正控制者。矩阵合并模型也易操作,而且在控制限值为50%的条件下,它能计算出公司真正的控制者。然而,如果由于没有控制者能达到50%的限值而降低限值水平,该模型可能无法准确识别控制者。
In this paper, we first define the structure of the non-cross-share pyramid to be studied by using graph theory. Then compare the weakest link method and the matrix combination method with an example to find out that the simplest operation model is the weakest link model. However, This model does not accurately identify the true controller of the company. The matrix merge model is also easy to use and calculates the true controller of the company with a control limit of 50%. However, if the limit is lowered because no controller can reach the 50% limit, the model may not accurately identify the controller.
