外部压力、公司治理与环境信息披露质量——基于煤炭行业上市公司的实证检验

External Pressure,Corporate Governance and the Quality of Environment Information Disclosure ——Based on the Empirical Test of the Coal Industry Listing Corporation

将煤炭行业上市公司作为研究对象,在运用内容分析法对其2008—2012年环境信息披露质量进行评价的基础上,实证检验外部压力、公司治理对环境信息披露质量的影响。研究发现,样本期间我国煤炭行业上市公司环境信息披露质量整体呈上升趋势,但各公司间差异较大;外部压力对环境信息披露质量起到了积极的提升作用,环境信息披露制度的颁布和执行成为公司绿色行为的重要驱动力;有效的公司治理能明显改善环境信息披露质量,尤其是股权制衡机制、董事会和独立董事作用显著,但控股股东并未发挥出应有的作用。

Choosing Chinese coal listed companies as sample, and using content analysis method to appraise the quality of en- vironmental information disclosure from 2008 to 2012. Then, it make empirical test on the effect of external pressure and cor- porate governance. The results show that the quality of environmental information disclosure overall presents an upward trend, but varies among companies. External pressure has positive effect. The promulgation and implementation of environmental in- formation disclosure plays an important role. Corporate governance can improve the quality of environmental information disclo- sure, especially the equity restriction, board and independent directors, but Controlling shareholder does not play its role.
