Under the"carbon peaking and carbon neutrality"goal,low-carbon technological innovation is the key to achieve a win-win situation between environmental protection and economic growth.Based on the panel data of China's A-share industrial enterprises lis-ted on Shanghai and Shenzhen Stock Exchanges from 2014 to 2020,this study examines the impact of proactive corporate environmental responsibility on low-carbon technology innovation and its mechanism by using the fixed effect model from the perspective of external stakeholders.The results show that enterprises'fulfillment of proactive environmental responsibility is helpful to obtain government sub-sidies,ease financing constraints,thus promoting low-carbon technology innovation activities.Further research shows that media atten-tion can increase the promotion of proactive environmental responsibility to government subsidies,but it will weaken the mitigation of fi-nancing constraints.
