求以下这段文字的专业翻译（战略管理方面论文）This article tests a transactions cost theory of vertical integration with data from the U,S. automobile industry.

A testable model is then developed, which is estimated by using probit techniques. The results support the view that transactions cost considerations surrounding the development and deepening of human skills have important ramifications for delineating efficient organizational boundaries.
