摘要 公司多元化能使企业发生深刻的变化,它是一种战略,并且已成为现代的工业企业成长到一定阶段以后普遍采用的一种成长方式。现有文献的研究将重点纷纷聚焦于公司多元化对于公司绩效的影响,然而本文认为深入了解公司多元化有必要探究其内在动因。本文认为,不同性质的企业,其追求公司多元化的内在动因是不同的。并通过对2012年A股上市的制造业企业的实证研究,发现家族企业的股权集中度与公司多元化成正相关关系,国有企业的股权集中度与公司多元化成负相关关系。本文用内部资本市场理论与防御假说对上述现象进行了解释。
本文认为,由于我国产权歧视现象的存在,家族企业很难获取外源融资,因此其融资能力相对国有企业处于弱势中。它们希望通过公司多元化,来建立内部资本市场,以弥补此类缺陷。另外,由于家族成员在公司中投入了大量的私人财产,他们更看重的是降低公司风险,而公司多元化的突出优势就在于能够分散风险,经由运营不同的业务,使得公司持续发展。这样,公司就不会被某个行业的经营不善所拖累而导致整体危机,因此很好地预防了企业面临的风险。
国有企业的融资环境相对宽松,缺乏进行公司多元化的动力。同时,在我国新兴经济和转轨经济的制度背景下,股权集中度高的国有企业,其管理人员常常由政府相关部门派人担任,使得管理人员与大股东的利益一致,随着股权集中度的提高,政府及经营者的多元化成本会上升,因此,国有企业更倾向于集中化策略。

ABSTRACT
Corporate diversification is a strategy and has become a way of growinginto a modern industrial enterprise which is commonly used after a certain stage.
While corporate diversification has received considerable attention from itsimpact on the performance of company, this paper argues that explored thecompany's intrinsic motivation is necessary. This paper considers how theidentity of owners moderates the impact of o\ynership concentration ondiversification strategies. Based on a study of 472 listed manufacturingenterprises on 2012,I found that family ownership concentration has a positiveimpact on corporate diversification while the impact of state ownershipconcentration is negative. This is the first study to identify the ownershipidentity of different corporate.
Because of the property rights discrimination, it is more difficult for familyenterprise to access to external finance, and its financing capacity has beengreatly constrained. They have a strong incentive to be diversified in order toestablish an internal capital market to ease external financing difficulties it faces.
In addition, because the family business personnel in the company invested a lotof private property, they pay more attention to reducing the company's risk. Dueto the centralized management of enterprise development susceptible to highmarket capacity constraints, once the business is in crisis, companies have noother product can make; while diversification has a significant advantage - riskdiversification, enterprise engaged in the production of multiple products or byareas of industry operations, achieve business expansion, allowing companiesnot because of a deterioration in certain areas of the business environment andthe overall damage, thus effectively reducing the overall risk of the enterprise.
State-owned enterprises are the main target of China's four majorstate-owned banks to lend, and its financing relatively relaxed environment;addition, in the institutional context of emerging economies and transitioneconomies, a high degree of concentration of ownership of state-ownedenterprises, their managers are often sent by the relevant governmentdepartments person as such benefits managers and major shareholders in linewith the increase of concentration of ownership, the cost of government andoperators of diversification will increase, therefore, the state-owned enterprisestend to centralize policy.
