Numerous studies have revealed that developing green technology innovation is extremely important for minimizing haze pollution. However, limited by serious endogenous problems, research rarely focuses on the effect of haze pollution on green technology innovation. Based on a two-stage sequential game model including both production and government departments, this paper mathematically deduced the effect of haze pollution on green technology innovation. Then China's central heating policy is considered a natural experiment in our study to verify whether haze pollution is the key factor affecting the development of green technology innovation. The result that haze pollution significantly inhibits green technology innovation is confirmed, and this negative impact is mainly concentrated on substantive green technology innovation. Robustness tests have been performed, and the conclusion is still valid. Moreover, we find that government behavior can significantly affect their relationship. Specifically, the government's economic growth target will increase the haze pollution's ability to block the development of green technology innovation. However, if the government has a clear environmental target, their negative relationship will weaken. Based on the findings, targeted policy insights are presented in this paper.
众多研究表明，发展绿色技术创新对于最大限度减少雾霾污染极为重要。然而，受严重内生问题的限制，研究很少关注雾霾污染对绿色技术创新的影响。基于一个包含生产部门和政府部门的两阶段序贯博弈模型，本文从数学上推导了雾霾污染对绿色技术创新的影响。然后，在我们的研究中，将中国的集中供暖政策视为一项自然实验，以验证雾霾污染是否是影响绿色技术创新发展的关键因素。研究证实了雾霾污染显著抑制绿色技术创新这一结果，且这种负面影响主要集中在实质性绿色技术创新上。已进行了稳健性检验，结论仍然有效。此外，我们发现政府行为会显著影响它们之间的关系。具体而言，政府的经济增长目标会增强雾霾污染对绿色技术创新发展的阻碍能力。然而，如果政府有明确的环境目标，它们之间的负相关关系将会减弱。基于这些研究结果，本文提出了有针对性的政策见解。
