中文摘要：

本文对我国沪市重污染行业上市公司2008--2012年社会责任报告中所披露环境信息的内容、水平及鉴证情况进行了全面的分析，发现以社会责任报告方式披露环境信息的公司近5年持续增加，尽管七成以上公司披露社会责任报告是对上交所《通知》要求的呼应，但自愿以社会责任报告方式发布环境信息的公司仍逐年增加；上市公司环境信息披露内容分布具有层次性，软披露信息多，硬披露信息少，尤其是环境绩效指标类信息披露少；环境信息披露水平存在显著的行业差异，且呈现出以2010年为拐点，先升后降的特点；包括环境信息在内的社会责任报告信息鉴证在我国尚处于起步阶段，鉴证数量和质量都有待提升。未来我国上市公司环境管理水平和环境绩效仍有待提升，环境信息披露及鉴证相关制度安排亦有待完善。
