So first we dont take the endogenesis into account and use OLS to estimate the relationship between capital structure and performance. Then we use instrumental variable to establish a new equation to eliminate the influence of endogenesis. We will compare the two results to find a correct relationship of capital structure and performance.

因此，本文首先不考虑变量间的内生性影响，采用普通最小二乘法，研究资本结构与公司绩效之间的相互关系，然后引入工具变量，重新建立模型以消除二者之间的内生性关系，并与不考虑内生性影响的结果进行比较，以求得出二者之间较为可靠的相关关系。
