我国现有环境规制侧重于将干预作为清洁技术需求方的企业,却忽略了对清洁技术研发的引导。文章将作用于企业的排污权交易与引导研发方向的清洁技术研发补贴相结合,通过构建理论模型考察二者搭配是否有助于清洁技术水平的提高,并使用我国工业二氧化硫排放权交易试点的省际数据对理论模型进行了实证检验。结果表明:(1)工业二氧化硫排污权交易在观察期内提高了试点省份的清洁技术创新水平,这与理论模型结论相一致;(2)我国试点省份的排污权交易政策未能发挥减排作用,这与理论模型结论不一致;(3)清洁技术研发补贴只有与排污权交易相结合才能充分发挥其政策效果;(4)清洁技术研发补贴对相应的研发投入存在双门槛效应,补贴并非越高越好。因此,为提高我国清洁技术创新水平,政府应注重环境规制搭配,并控制好补贴力度。
The existing environmental regulation in our country focuses on enterprises that take intervention as the demand side of clean technology but neglects to guide the research and development of clean technology. This article will combine the emission trading of the enterprise with the R & D subsidy of clean technology that guides the R & D direction. By constructing the theoretical model, whether the combination of the two will help to improve the level of clean technology and using the pilot scheme of China’s industrial sulfur dioxide emissions trading The data of the theoretical model empirical test. The results show that: (1) The emission trading of industrial sulfur dioxide increased the level of clean technology innovation in pilot provinces during the observation period, which is consistent with the theoretical model; (2) Emissions trading policies of pilot provinces in China failed to play a role of emission reduction , Which is inconsistent with the conclusion of the theoretical model; (3) R & D subsidies for clean technologies can give full play to their policy effects only when they are combined with emissions trading; (4) R & D subsidies for clean technology have a double threshold effect on the corresponding R & The better. Therefore, in order to improve the level of innovation of clean technologies in our country, the government should pay attention to the coordination of environmental regulations and control the subsidies.
