中文摘要：	董事会结构是公司治理理论的主要研究对象，怎样的公司治理结构能够最大限度的支持公司的发展一直是国内外学者探讨的核心问题。然而平常我们看到的这类研究基本上都是基于代理理论，认为董事会只是起到一个决策和监督的作用。 近些年来，随着基于资源依赖视角，对董事会作用机理的研究越来越多。人们也意识到紧紧把董事看作是一个决策者和监督者是片面的。资源依赖理论认为董事是公司与外部环境联系的渠道，通过他们与外部环境的各种联系，提供给公司所需要的关键资源，或者保证这些关键资源的供应（Preffer and Salancik，1994）。公司董事会是企业管理对外部环境依赖性的一种机制（Pfeffer and Salancik，1978），可以降低外部环境的不确定性（Pfeffer，1972），并且可以降低因与环境相互依存而发生的交易成本（Williamson，1984）。总之，他们认为，调整董事会构成是企业应对外部环境不确定性的一种机制。 对环境不确定性的研究也一直是组织理论的研究重点。本文的研究内容就是，将外部环境不确定性与董事会联系起来，研究在资源依赖视角下，外部环境不确定性与董事会中各类董事的关系，以及验证公司中是否存在这种通过调整董事会构成来应对外部环境变化的机制。 本文使用的样本是国内A股上市的房地产企业，主要是因为房地产行业在最近几年内经历了前所未有的环境变化。样本公司81家，07、08、09三年共计243个样本年数据。在借鉴前人对董事会按提供资源不同进行的分类，结合我国特有的国情，将样本公司的董事会进行重新分类。然后按照本文设计的环境不确定性指标计算每个公司环境不确定性指数。研究指数与分类董事的关系。 研究结论总体上同资源依赖理论与组织理论的观点类似。研究证明面临的环境不确定性水平的高低，会影响到董事会的结构。企业中存在通过调整董事会构成来应对外部环境变化的机制。同时还发现，在国有控股企业和非国有控股企业中，这种管理外部环境不确定的机制有显著不同。
英文摘要：	Board structure is the main object of Corporate Governance study, how the corporate governance structure can maximize supporting the company's development has been the core issue of domestic and foreign scholars. However, such studies we've seen are basically based on agency theory, that the Board only acts as a decision-making and supervision actor. In recent years, with the perspective of resource dependence based on the mechanism of action of the board more and more. It is also aware that closely to policy-makers and directors as a supervisor is one-sided. Resource dependence theory is that the directors of the company's channels of contact with the external environment, through their linkages with the outside environment, providing critical resources needed for the company, or to ensure the supply of these critical resources . Management Board is dependent on a mechanism external environment , can reduce the uncertainty of the external environment ,and can reduce the interdependence and the environment due to transaction cost . In short, they argue, constitute the Board to adjust the external environment of enterprises as a mechanism of uncertainty. Uncertainty of the environment has also been a focus of organizational theory research. The content of this study is that the external environment of uncertainty linked with the board to study the resource dependence perspective, external environmental uncertainty and the relationship between the board directors of all kinds, and to verify the existence of such companies by adjusting the composition of the Board Changes to the mechanism of the external environment. The sample used in this article is the A-share listed real estate companies, mainly because of the real estate industry in recent years has experienced unprecedented changes in the environment. 81 sample companies, 07,08,09 in three years ,total of 243 samples of data. In the previous reference to the Board carried out according to different classification of resources, combined with our unique national conditions, the sample re-classification of the company's board of directors. Then designed according to this index to calculate the environmental uncertainty environmental uncertainty index for each company. Study the relationship between index and classification of directors. Studies have shown that the level of environmental uncertainty faced, will affect the structure of the board. Companies by adjusting the composition of the Board exists to respond to changes in the mechanism of the external environment. It was also found in the state-owned holding enterprises and non state-owned holding enterprises, the management mechanism of the external environment of uncertainty were significantly different.
