基于交易费用理论的企业边界纵向一体化研究

交易费用理论认为，企业的最优边界在市场费用等于企业协调成本那一点，交易费用中的企业规模实质上是企业的纵向规模即纵向边界，企业纵向规模的扩张主要通过纵向一体化来实现。虽然纵向一体化能够有效地削弱人的机会主义和有限理性，克服不确定性，降低交易成本，但它并不必然是企业发展的一种好办法，企业发展到一定阶段，纵向分拆策略是有效的。企业的纵向边界呈现扩张与收缩交互进行的局面。

Based on Transaction Cost Theory Vertical Boundary Study

According to transaction cost theory,the enterprise often appears,when its marketplace costs are equal to the harmonization costs.Firm scale in transaction cost means essentially the firm vertical scale or boundary.The firm vertical scale dilation comes true mainly by vertical integration.Though reviewing the vertical integration,we point out the vertical integration can weaken people's opportunism and limited rationality,overcome uncertainty,and reduce business cost.However,it is not a good way for the firm developing.When the firm develops to a certain stage,vertical decomposition is efficiency.The enterprise vertical boundary displays the interactive aspect of dilating and decomposing.
