Since access to capital and other corporate financ问题补充: financing decisions depend on the extent of agency costs and asymmetric information (e.g., Titman and Wessels, 1988; Rajan and Zingales, 1995) and these attributes likely differ between public and private companies, we include financial leverage as a control variable.

由于资本和其他企业融资决策的的获取取决于业务成本和非对称信息的程度（例如，Titman和Wessels，1988年；Rajan和Zingales，1995年）而且这些属性可能在上市公司和私营公司之间有所不同，因此我们把包括财务杠杆也作为控制变量。
