基于深市上市公司2002—2005年四年的面板数据,本文选用深市信息披露考评结果衡量公司透明度,采用有序logistic回归及二阶段最小二乘法(2SLS)检验了公司治理机制对公司透明度的影响。研究结果表明:上市公司所在地区的市场化程度越高、政府干预程度越低、法治及中介组织发育水平越高,公司透明度越高;审计意见为标准无保留的公司有更高的公司透明度,提高公司高管人员的持股比例与第一大股东持股比例、扩大董事会的规模可以增加公司透明度;是否发行B股、是否发行H股、会计事务所是否为“国际五大”对公司透明度无显著影响,但这些公司的透明度为优秀的可能性更大;两职兼任、独立董事比例、委员会数量对公司透明度均无显著影响;企业规模越大、会计绩效越好、银行负债率越低,公司透明度越高。
Using panel data of listed companies from 2002 to 2005, this research paper investigates the influences of corporate governance on corporate transparency. The conclusions are as follows. The more developed the market, legal institutions and intermediary organizations, the less frequent the govermnent intervention, the more transparent the companies are. Companies with clear opinion are more transparent than other companies. Increasing the ownership of executives and controlling shareholders and the hoard size can help enhance corporate transparency. B- or H-share issuing," big-five" external auditor, duality, proportion of independent directors and the number of committees are not significantly related to corporate transparency; while the higher the firm size and the financial performance, the lower the leverage, the more transparent the companies are.
