中国公司治理与自愿信息披露的实证分析

股权结构以第一大股东持股比例表示,董事会的构成以独立董事在董事会中的比例、董事长与总经理是否二职合一两个变量表示,而自愿信息披露指数则按照对公司年报在非财务信息、财务信息方面的评分计算.结果显示:自愿信息披露指数与第一大股东持股比例呈U型关系,与独立董事在董事会中的比例、董事长总经理是否两职合一无显著相关性;规模大的上市公司,更倾向于实施自愿信息披露.

Empirical Study on Corporate Governance and Voluntary Disclosure in China

This paper examines the impact of ownership structure and board composition on voluntary disclosure. Ownership structure is characterized by first ownership, and board composition is proxied by the percentage of independent directors. Voluntary disclosure is measured by an aggregated disclosure score of non-financial and financial information. Our results show that both lower and higher first ownership are associated with increased disclosure. The number,not percentage,of independent directors improve corporate disclosure. We also find that larger firms had greater disclosure.
