In areas with serious pollution problems, the government designates a special emission limit (SEL) for pollution control and environmental protection in China. This paper examines the effects of chemical oxygen demand (COD) SEL on firms' production activity and market performance in the pulp and paper industry in the Lake Tai area in China. Using firm-level data, we employ a difference-in-differences strategy and find that SEL has a negative impact on the production scale, profitability, and market size of the regulated firms, while showing no significant impact on firm exports. The heterogeneity tests suggest that the impact of SEL on production and market performance varies with firm ownership, firm size, and target market. The reallocation effect of production shifts extra production from exited firms to existing firms, which explains the expansion of production scale and market size for SOEs and large-sized regulated firms. Compared with the decline of production scale, the inventory alleviation effect reduces the negative impact of stricter environmental regulation on firm performance.
在中国污染问题严重的地区,政府为污染控制和环境保护设定了特殊的排放限值(SEL)。本文考察了化学需氧量(COD)SEL 对中国太湖地区制浆造纸行业企业生产活动和市场绩效的影响。本文利用企业层面的数据,采用双重差分策略,发现 SEL 对受监管企业的生产规模、盈利能力和市场规模产生负面影响,而对企业出口没有显著影响。异质性检验表明,SEL 对生产和市场绩效的影响因企业所有制、企业规模和目标市场而异。生产的再配置效应将额外的生产从退出企业转移到现有企业,这解释了国有企业和大型受监管企业生产规模和市场规模的扩大。与生产规模的下降相比,库存缓解效应减轻了更严格的环境法规对企业绩效的负面影响。
