近年来，随着气候变化的日益严峻，绿色发展和生态环境保护成为全球关注的热点。生态环境保护的公共属性引发了对企业环境信息披露的外部合规性需要，而企业是碳排放的主体，环境信息披露机制对推动绿色发展具有重要意义。该机制能让公众及时了解企业在改善环境方面所做的努力，从而参与企业的环保监督工作。因此，有必要探究政府如何发挥主导作用，加强对重点行业企业的监督和指导，建立完善的环境信息披露制度引导和激励约束机制，推动企业环境信息披露质量的提升。

某些地方的企业可能出于追求短期经济效益的考虑，忽视了环保法规的约束，甚至将环保视为一种负担而非责任。由于企业被要求完成一定的环保指标，但这些指标往往是通过行政命令或者政治动员的方式，而非基于企业自身对环保的自觉认识和行动来实现的。虽然短期内可能取得一定的成效，但并不利于企业形成真正的环保意识和责任感。这种情况下，即使环保政策加强地方监督，但由于监管力量的不足或者执行力度的不够，一些企业的违法违规行为仍然难以得到根本性的遏制。中央环保督察是推动地方生态文明建设、促进绿色发展的一项重要举措，通过加强对地方政府及部门履职尽责情况的监督检查，推动其加强环保工作，倒逼企业更加重视环保工作，规范自身的环境披露行为。这种“倒逼机制”不仅有助于解决当前环保工作中存在的一些问题，而且有助于推动生态文明建设发展。而且，督察与披露本质上都是强调“政府—公众—企业”三方共同参与和监督的环境管理模式，从这个角度来看，二者具有内在一致性。

由于中央环保督察分批次在不同地区开展，不同批次的企业接受督察的时间点不一致，因此选取我国2013―2022年A股上市企业为样本，实验组是16类重污染行业企业，对照组是除金融外的其他企业，采用多期双重差分法，对督察前后的环境信息披露质量进行检验。此外，按照企业性质对样本进行分组检验，并加入政府环保关注和媒体监督两个调节变量。研究发现，中央环保督察与环境信息披露质量正相关，而且与国有企业相比，中央环保督察对环境信息披露质量的正向作用在民营企业更加显著，政府环保关注在一定程度上削弱这种正向关系，而媒体监督则强化该正向调节作用。

In recent years, with the increasing severity of climate change, green development and ecological environmental protection have become a global concern. The public attribute of ecological environmental protection has triggered the need for external compliance with the disclosure of corporate environmental information, while enterprises are the main body of carbon emissions, and the environmental information disclosure mechanism is of great significance in promoting green development. The mechanism enables the public to keep abreast of the efforts made by enterprises to improve the environment, so that they can participate in their environmental protection monitoring work. Therefore, there is a need to explore how the government can achieve the effect of strengthening the supervision and guidance of enterprises in key industries, establishing a sound environmental information disclosure system and incentive and constraint mechanism, and promoting the improvement of the quality of enterprises' environmental information disclosure.

Enterprises in certain places may ignore the constraints of environmental protection regulations or even regard environmental protection as a burden rather than a responsibility for the sake of pursuing short-term economic benefits. As enterprises are required to accomplish certain environmental protection targets, these targets are often achieved through administrative orders or political mobilization rather than on the basis of the enterprises' own conscious awareness and action on environmental protection. Although some results may be achieved in the short term, they are not conducive to the formation of a true sense of environmental awareness and responsibility on the part of enterprises. In this case, even if the environmental protection policy strengthens local supervision, it is still difficult to fundamentally curb the illegal behaviors of some enterprises due to insufficient supervisory power or insufficient enforcement. Central environmental protection inspection is an important initiative to promote local ecological civilization and green development. By strengthening the supervision and inspection of local governments and departments in fulfilling their duties and responsibilities, it pushes them to strengthen their environmental protection work, and forces enterprises to pay more attention to environmental protection and standardize their own environmental disclosure behavior. This "forcing mechanism" not only helps to solve some of the current problems in environmental protection, but also helps to promote the development of ecological civilization to a deeper level. Moreover, both inspection and disclosure are essentially environmental management modes that emphasize the joint participation and supervision of "government-public-enterprise", and from this point of view, they are inherently consistent.

Since the central environmental protection supervision is carried out in batches in different regions, and the time points for enterprises in different batches to receive supervision are not consistent, the A-share listed enterprises in China from 2013 to 2022 are selected as samples. The experimental group is the enterprises in sixteen types of heavy pollution industries, and the control group is the enterprises other than the financial sector. The quality of environmental disclosure before and after inspections is examined using a multi-period difference-in-differences approach. In addition, the samples are tested by groups according to the nature of enterprises, and two moderating variables of government environmental concern and media supervision are added. The study finds that the central environmental protection supervision is positively correlated with the quality of environmental information disclosure. Moreover, compared with state-owned enterprises, the positive effect of central environmental supervision on the quality of environmental information disclosure is more significant in private enterprises, and government environmental protection attention weakens this positive relationship to a certain extent, while media supervision strengthens the positive moderating effect.
