环境税、环境补贴与清洁技术创新:理论与经验
发布时间：2018-12-15 13:43
【摘要】：本文利用偏向性技术创新理论和上市公司数据实证研究了环境税和环境补贴对我国清洁技术创新的影响。理论模型研究表明,环境税和环境补贴对清洁技术创新的影响主要取决于清洁能源和化石能源的替代弹性。当清洁能源和化石能源互补时,环境税会抑制清洁技术创新,环境补贴会促进清洁技术创新,但对化石能源技术创新的作用更大。相反,当清洁能源和化石能源相互替代时,环境税和环境补贴能够促进清洁技术创新,抑制化石能源技术创新。技术外溢降低了替代弹性的临界点,提高了环境税和环境补贴促进清洁技术创新的效果。利用系统GMM和Tobit方法实证研究表明,我国目前的清洁能源和化石能源互补,使得环境税抑制了清洁技术创新,环境补贴能够促进清洁技术创新,但效果较小。政府政策应从全产业链角度扩大清洁技术应用范围,提高清洁能源和化石能源的替代弹性。
[Abstract]:In this paper, the impact of environmental tax and environmental subsidy on clean technology innovation in China is studied by means of biased technology innovation theory and listed company data. Theoretical model studies show that the impact of environmental taxes and subsidies on clean technology innovation mainly depends on the alternative elasticity of clean energy and fossil energy. When clean energy and fossil energy complement each other, environmental tax will restrain clean technology innovation, environmental subsidy will promote clean technology innovation, but it will play a more important role in fossil energy technology innovation. On the contrary, when clean energy and fossil energy replace each other, environmental tax and environmental subsidy can promote clean technology innovation and inhibit fossil energy technology innovation. Technology spillover reduces the critical point of substitution elasticity and improves the effect of environmental tax and environmental subsidy to promote clean technology innovation. The empirical study of GMM and Tobit shows that the current clean energy and fossil energy complement each other in China, which makes the environmental tax restrain the innovation of clean technology, and the environmental subsidy can promote the innovation of clean technology, but the effect is relatively small. The government policy should expand the application range of clean technology from the angle of the whole industry chain and improve the elasticity of substitution of clean energy and fossil energy.
