Based on an analysis of 643 listed firms in clean technology sectors, this study explores the nonlinear impact of the government's environmental attention (GEA) on firms' green innovation by exploiting threshold and quantile regression techniques on Stata 17. We show that a double threshold exists when the level of the GEA is 51 or 104, above which the positive impact of the GEA on green innovation in cleantech firms significantly diminishes. The results from the quantile regression further indicate that cleantech firms receive almost no benefits from the GEA at lower levels of green innovation. Thus, policy-makers designing environmental policies should consider that the marginal benefit of environmental attention on green innovation wanes beyond certain levels, especially for firms that lack sufficient enthusiasm for innovation.
基于对 643 家清洁技术领域上市公司的分析,本研究利用 Stata17 中的门槛和分位数回归技术,探讨了政府环境关注(GEA)对企业绿色创新的非线性影响。我们表明,当 GEA 的水平为 51 或 104 时,存在双重门槛,在此之上,GEA 对清洁技术企业绿色创新的积极影响显著减弱。分位数回归的结果进一步表明,绿色创新水平较低的清洁技术企业几乎无法从 GEA 中获益。因此,制定环境政策的政策制定者应该考虑到,环境关注对绿色创新的边际效益在达到一定水平后会减弱,特别是对于那些对创新缺乏足够热情的企业。
