随着国民经济的快速发展，减少污染、保护生态环境、提高资源利用率，以实现人类与自然和谐相处的重要性日益增长。而作为市场经济重要主体的上市公司，尤其是能源消耗多和污染物排放量大的钢铁、制造业等重污染行业的上市公司，其日常经营和生产活动都可能会破坏生态、污染环境、浪费资源，环保事故时有发生，甚至导致严重的环境事件。加强对上市公司环保监管的一个措施就是建立健全环境信息公开制度，加强对其环境行为的规范，使得监管机关以及投资者等主体及时获取上市公司的环境表现以及风险信息。

本文选取2019年度北京、上海、辽宁、湖南、重庆、陕西六省沪深主板上市公司的年度报告和社会责任报告作为研究对象，针对上述主体环境类行政处罚以及重点排污单位信息的披露情况进行统计和整理，并分析影响环境信息披露质量的因素。研究发现目前存在的主要不足为：立法方面，有关环境信息披露的条文较为分散，层级较低且内容不够详细；执法方面，环保部门与证券部门交流较少，缺乏强有力的第三方监管；守法方面，上市公司对于披露环境信息的重视程度低，投资者、社会公众等主体对于环境信息的需求并不强烈。

研究结果表明，通过提高环境信息披露立法的效力层次，实现强制披露，建立统一规范的披露标准；提高投资决策与环境信息的相关性，环保、证券、税务等部门形成联合奖惩机制，并逐步建立专业的第三方鉴证机构；完善公司内部治理结构，加强对公众的环保宣传与教育，充分发挥新闻媒体和NGO的正向引导以及监督作用等举措，可以完善上市公司环境信息披露体系以及企业环境信息公开体系，为推动生态文明建设提供助力。

With the rapid development of the national economy, the importance of reducing pollution, protecting the ecological environment, improving resource utilization, and achieving harmony between mankind and nature is increasing. As an important subject of the market economy, listed companies, especially listed companies in heavy-polluting industries such as steel and manufacturing that consume a lot of energy and emit large amounts of pollutants. Environmental accidents occur from time to time, and even lead to serious environmental incidents. One measure to strengthen environmental supervision of listed companies is to establish a sound environmental information disclosure system and strengthen the regulation of their environmental behavior, so that regulatory agencies and investors and other entities can obtain timely information on the environmental performance and risk of listed companies.

This article selects the 2019 annual reports and social responsibility reports of listed companies on the Shanghai and Shenzhen main boards in Beijing, Shanghai, Liaoning, Hunan, Chongqing, and Shaanxi as the research objects. Starting from the factors that affect the quality of environmental information disclosure, statistics and sorting out the information disclosure of the above-mentioned subjects' environmental administrative penalties, and key pollutant emission units. The research found that the main shortcomings of current information disclosure are: in legislation, the provisions on environmental information disclosure are relatively scattered, with low levels and not detailed enough; in law enforcement, environmental protection departments and securities departments have less communication, which makes environmental information disclosure lack of strong third-party supervision; in terms of compliance, listed companies pay little attention to the disclosure of environmental information, and investors, the public and other entities do not have a strong demand for environmental information.

Research indicates: improve the level of effectiveness of environmental information disclosure legislation, achieve mandatory disclosure of environmental information by listed companies, and establish unified standards; environmental protection, securities, taxation and other departments will form a joint reward and punishment mechanism, and gradually establish professional third-party assurance agencies; improve the company's internal governance structure, strengthen environmental protection publicity and education to the public, and give full play to the positive guidance and supervision of news media and NGOs. Through the above measures, the corporate environmental information disclosure system will be improved to provide assistance to promote the construction of ecological civilization.
