| Modern corporation theory pointed out that Ownership structure was related with Corporation Performance. Ownership structure is the internal structure of firm, it is the foundation of corporation fathering, impacting the mechanism of corporation father. At the same time the corporation fathering also impacts the corporation performance.Because of different kinds of reasons, unsuitable ownership structure and low performance has become the biggest problem which puzzled our enterprises. How to set up a suitable ownership structure and improve the performance becomes the urgent and important problem.The thesis tries to set up a model to study the relation between ownership structure and company performance. During studying, we found that the company performance had relation with ownership structure. We try to find the internal reason why the ownership structure can impact the performance of the firm. First, we analyze the influence on the corporation fathering from ownership structure in two aspects: foundation and mechanism of firm fathering; then based on the model having set up, we use the actual data to verify it. By the theory and demonstration, we arrived at a conclusion: the relation between ownership and corporation performance is a U-curve, during the ownership structure rising, the performance will also increase, but after one point, the performance will not increase but descend.There are five chapters in this dissertation: Chapter 1, goes as the introduction of the whole thesis; Chapter 2, defines related concepts; Chapter 3 analyzes the impacting mechanism about ownership structure on the corporation performance via firm fathering; Chapter 4 use the actual data to do regress test to verify the relations; Chapter 5 to gives a conclusion and submits some suggestions about the ownership structure optimization. Among them Chapter 3 and Chapter 4 are the substantial of the thesis. |
