Prior research on capital structure by Titman (1988) utilizes structural equation models to find out the determinants of capital structure. In this paper, we use the same methodology and add another endogenous variable – stock return to construct two equations. One regards capital structure and the other one regards stock returns.

Titman (1988)曾利用求解结构方程模式的统计软体–LISREL找寻影响公司资本结构的隐藏因子,本文乃以此篇论文为基础并加以延伸,除了纳入原先的内生变数资本结构外,再加入另一个内生变数–股票报酬率来建立一个双向影响的结构联立方程式,以期研究资本结构与股票报酬率两者是如何交互影响,并是如何由许多因子所共同决定。
