The impact of blockchain on firms' environmental and social performance
研究了区块链专利对企业环境与社会绩效的影响，发现总体上呈负相关，但公司规模和研发投入会调节这一效应；美国首部有利区块链的立法出台后，区块链专利对环境绩效转为正向影响。
Abstract This paper studies the relationship between blockchain patents and firms' environmental and social performance. Using data from USPTO, we assess the effect of these patents on subcategories and aggregate grades for social and environmental dimensions. Our results show a negative main effect of blockchain‐related patents on social and environmental grades. However, this effect is moderated by company size and focus on R&D. We exploit the first legislation favorable to blockchain in the United States and find a positive effect of blockchain patents on environmental grades, showing a change in corporate behavior regarding the use of blockchain.
