Does the Eco‐Management and Audit Scheme Foster Innovation in European Firms?
研究欧洲企业采用生态管理与审计计划（EMAS）对生态创新的影响，基于30439家企业的面板数据，发现EMAS促进企业创新，尤其在中低技术制造业中与绿色专利正相关。
Abstract This paper studies whether environmental management systems can spur eco‐innovation, analyzing EMAS (Eco‐Management and Audit Scheme) adoption and patented innovations (at the European Patent Office) at firm level. It uses an original panel database of 30 439 European firms belonging to all sectors from 2003 to 2012. An original instrumental variable is implemented to control for potential endogeneity. The analysis reveals that EMAS adoption is conducive to more innovation at the firm level. The results vary across countries and sectors. In particular, EMAS is positively related to green patents for medium and low technology manufacturing. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment
