How Does Open Innovation Modify the Relationship between Environmental Regulations and Productivity?
研究了开放式创新策略（外部技术获取）如何中介环境规制对生产率的影响，发现国外技术有正向中介作用，而国内技术无显著作用，且内部研发投入起调节作用。
Abstract With increasingly severe environmental regulations, a pressing issue has been the need for firms to develop efficient strategies to achieve environmental protection and high productivity. Several environmental experts argue that firms can respond to environmental regulations through innovation; however, the question of how to innovate is unanswered in the environmental literature. Therefore, this study focuses on the open innovation strategy approach to respond to environmental regulations and maintain high productivity by incorporating the idea of innovation management. We first divide open innovation strategy into two modes of external technology acquisition: foreign and domestic. Next, we examine these modes' mediation effects on environmental regulations and productivity. In addition, we test the moderating effect of internal R&D on the relationship between external technology acquisition and productivity. Using data on 35 Chinese industrial sectors from 2001 to 2010, the empirical findings show that foreign technology significantly and positively mediates the link between environmental regulations and productivity, while domestic technology does not. Internal R&D investment, as an absorptive capacity, positively moderates the effect of foreign technology; however, it negatively moderates the effect of domestic technology on productivity.
