近日，碳排放权交易省部共建协同创新中心兼职研究员蔡程博士在《Frontiers in Ecology and Evolution》发表论文《Climate change, environmental regulations, and firms' efforts to reduce pollutant emissions》。
环境监管是实现环境保护的重要工具。本研究调查了气候变化如何影响企业通过环境法规减少污染物排放的行动。本文使用2006年至2013年中国规模以上工业企业的数据进行了汇总OLS回归分析。研究结果表明，企业会减少二氧化硫排放以应对气候变化，特别是在环境法规更加严格的情况下。横断面测试表明，在中央政府设立的“两个控制区”地区和地方政府执行更严格的环境法规的地区，企业在面对气候变化时更有效地减少污染物排放。然而，企业更倾向于降低生产率和实施“管道末端”干预，而不是进行更多的绿色创新。
本研究结果强调了企业如何在环境法规的压力下应对气候变化，以及生态考虑是否与经济目标一致或冲突。
Abstract
Environmental regulation is an important tool for achieving environmental protection. This study investigated how climate change affects firms' actions to reduce pollutant emissions through environmental regulations. We conducted a pooled OLS regression analysis using data from Chinese industrial firms that were above the designated size from 2006 to 2013. The results showed that firms reduce SO2 emissions in response to climate change, particularly when environmental regulations are more stringent. However, firms prefer to reduce productivity and implement “end-of-pipe” interventions than engage in more green innovation. Our findings highlight how firms deal with climate change under the pressure of environmental regulations and whether ecological considerations align or conflict with economic goals.
