 The impact of air quality on innovation activities in ChinaJingbo Cui, Shaoqing Huang and Chunhua Wang Journal of Environmental Economics and Management, 2023, vol. 122, issue C Abstract: Severe air quality hurts human capital and threatens innovative outcomes. Using unique data containing 12.8 million patent applications in China, this paper examines the causal effect of particulate matter with a diameter of 2.5 μm or less (PM2.5) on patent innovation. We estimate a two-stage least square model with thermal inversion as an instrumental variable. Our findings show that a one μg/m3 increase in the annual average PM2.5 concentration leads to a 1.3% decrease in the number of patents. Annual fluctuations in PM2.5 concentration levels across cities caused the total number of patents to decrease by 1.1% during the 2006–2010 period. From 2011 to 2015, the improvement in air quality increased the number by about 2.0%. It demonstrates another innovation co-benefit of improving air quality due to the tightened regulation.
