Robot adoption and corporate pollution emissions: Evidence from China

This study examines whether and how industrial robot adoption affects corporate pollution emissions. Using a sample of 163,301 firm-year observations from the Chinese industrial enterprises for the period 2004-2014, we find that firm's robot adoption is positively related to pollution emissions reduction. Further mechanism tests show that the adoption of robots in production can improve a firm's productivity and alleviate a firm's financial constraint, thereby increasing the firm's pollution emissions reduction. In addition, we find that the above-mentioned effect of robot adoption on a firm's pollution emissions reduction is more pronounced for firms headquartered in regions with strong environmental regulations, firms that are high efficiency of pollution treatment and high technology-intensive, firms that have gone public and state-owned enterprises. Altogether, this study provides the first micro evidence on the relationship between robot adoption and corporate pollution emissions, providing significant implications for the world's sustainable development.
