从我国高度集中的股权结构出发,建立理论模型分别研究在单一代理关系下,影响大股东掏空行为的主要因素,以及在双重代理关系下,大股东与管理层之间的掏空-自利博弈行为及其主要影响因素.证明了:1)在单一代理关系下,影响大股东掏空行为的因素为公司成长性、中小投资者保护水平以及大股东持股比例.公司成长性越高、中小投资者保护水平越高、大股东持股比例越高,大股东的掏空程度就越低.2)在双重代理关系下,影响大股东掏空行为的因素为大股东对公司的了解程度和专业能力、中小投资者保护水平以及大股东持股比例.大股东对公司的了解程度和专业能力越高、中小投资者保护水平越高、大股东持股比例越高,大股东的掏空倾向和掏空程度就越低.3)在双重代理关系下,影响管理层自利行为的因素为公司成长性、中小投资者保护水平以及管理层薪酬绩效敏感度.公司成长性越高、中小投资者保护水平越高、管理层薪酬绩效敏感度越高,管理层的自利倾向和自利程度就越低.
In this paper,we frame two theoretical models in concentrated ownership environments to study the determinants on tunneling and managerial entrenchment.We find that:(1) When there are only agency problems between controlling shareholder and minority shareholders in a firm,better investment opportunities,higher legal investor protection,and higher ownership by controlling shareholder will result in less tunneling.(2) When there are dual principal-agent problems in a firm,better knowledgeable of controlling shareholder,higher legal investor protection,and higher ownership by controlling shareholder will result in lower probability and lower extent of tunneling.(3) When there are dual principal-agent problems in a firm,better investment opportunities,higher legal investor protection,and higher pay-performance sensitivity will result in lower probability and lower extent of managerial entrenchment.
