本文以中国上市公司为研究对象,考察了大气污染对企业创新的影响。我们的研究结果表明,总部设在空气污染严重的城市的企业往往较少参与创新活动。为了更明确地确定因果关系,我们建立了一个2SLS的空气质量是由当地的热逆温仪表。造成这种负面影响的主要原因是人才外流,特别是高技能员工的移徙。此外,这种负面影响对于雇员工资低的企业和属于竞争性行业的企业更为明显。结果是强大的各种模型规格和替代措施。
This study investigates the influence of air pollution on firm innovation by using Chinese listed firms. Our results indicate that firms headquartered in a city with severe air pollution tend to engage less in innovation activities. To more explicitly identify causality, we establish a 2SLS where the air quality is instrumented by the local thermal inversions. This negative effect is primarily driven by brain drain channels, specifically the migration of highly skilled employees. In addition, such a negative effect is more pronounced for firms with low employee salaries and those belonging to competitive industries. The results are robust to a variety of model specifications and alternative measures.
