With the data of Chinese A-share-listed companies from 2004 to 2017, this paper builds a difference-in-differences model to investigate the impact of air pollution collaborative governance on green technology innovation. The main results show that air pollution collaborative governance promotes green technology innovation, and a series of robustness tests also verify this conclusion. Patent heterogeneity analysis suggests that air pollution collaborative governance increases the number of green utility model patents, but has no obvious impact on green invention patents. In terms of enterprise heterogeneity, air pollution collaborative governance can effectively stimulate the non-heavy-polluting enterprises to innovate green technology, but the incentive effect on heavy-polluting enterprises is not evident. Moreover, by constructing a mediating effect model and a moderating effect model, mechanism analysis reveals that R&D investment plays a positive mediating role in the impact of air pollution collaborative governance on green technology innovation, and the increase of government subsidy also enhances the promotion effect of air pollution collaborative governance on green technology innovation.
本文利用 2004-2017 年中国 A 股上市公司数据，构建了一个双重差分模型，以研究大气污染协同治理对绿色技术创新的影响。主要结果表明，大气污染协同治理促进了绿色技术创新，一系列稳健性检验也验证了这一结论。专利异质性分析表明，大气污染协同治理增加了绿色实用新型专利的数量，但对绿色发明专利没有明显影响。在企业异质性方面，大气污染协同治理能够有效激发非重污染企业创新绿色技术，但对重污染企业的激励效果并不明显。此外，通过构建中介效应模型和调节效应模型，机制分析表明，研发投入在大气污染协同治理对绿色技术创新的影响中发挥了积极的中介作用，政府补贴的增加也增强了大气污染协同治理对绿色技术创新的促进作用。
