摘要
基于2014-2021年披露环保数据的A股上市公司样本,匹配城市层面空气质量指数,考察企业环保投资对城市空气质量的影响.研究发现,在考虑平均气温、平均风速、降水量等气候因素后,企业环保投资能够释放"环境红利",有效治污减霾降碳,显著提升城市空气优良率.企业环保投资的空气质量提升效果主要通过源头污染预防而非末端污染治理效应实现.对于国有企业、具有环保背景董事占比更高的企业、制造业和环境规制力度较强的地区,企业环保投资的空气质量提升效果更加明显.进一步分析发现,企业环保投资能够实现经济红利和环境红利的互赢共生,达到企业价值和社会价值的有机统一.研究结论可为减污降碳一体谋划、有效提高城市空气质量提供决策参考.
Abstract
Based on disclosed environmental data from A-share listed companies between 2014 and 2021,matched with city-level Air Quality Index(AQI),this study investi-gates the impact of corporate environmental investments on urban air quality.The research reveals that,when considering factors such as average temperature,average wind speed,precipitation,and other climatic elements,corporate environmental invest-ments can unlock an"environmental dividend",effectively com-bating pollution,reducing haze,and lowering carbon emissions,leading to a significant improvement in the proportion of days with good air quality in cities.The enhancement of air quality re-sulting from corporate environmental investments is primarily a-chieved through the prevention of pollution at the source rather than the effects of end-of-pipe pollution control.The positive effects of corporate environmental investments on air quality are more pronounced for state-owned enterprises,companies with a higher proportion of directors with environmental backgrounds,manufacturing industries,and regions with stronger environmen-tal regulations.Further analysis indicates that corporate environ-mental investments can achieve a mutually beneficial synergy of economic and environmental dividends,achieving an organic u-nity of corporate and social values.The research conclusions provide valuable insights for comprehensive pollution reduction and carbon reduction planning,offering decision-making refer-ences for effectively combating urban pollution.
