EVIDENCE ON THE ROLE OF FIRM CAPABILITIES IN VERTICAL INTEGRATION DECISIONS
研究比较了企业能力与资产专用性对一家大公司自制或外购决策的影响，发现某些情况下资产专用性起决定作用，另一些情况下能力及组合因素更具解释力，并揭示了能力发挥作用的机制。
The capabilities approach to the firm postulates that firms vertically integrate activities for which they possess capabilities that are superior to potential suppliers'. The comparative contracting approach, in contrast, emphasizes high asset specificity as leading to vertical integration. This paper compares the two sets of explanations on make-or-buy decisions made by a large firm. It finds that in some cases asset specificity alone is determinant, but in others capabilities and combinations of considerations are explanatory. Analysis of the data also provides insights about the mechanisms through which capabilities operate. In particular, the similarity of the knowledge bases associated with various activities, and the time required to acquire knowledge, appear as important indicators of the importance of capabilities to vertical integration decisions.
