【摘要】：技术进步是实现碳减排的根本性措施,但不同的技术进步路径——技术自主创新与技术引进,以及不同国家、地区不同的技术进步路径,对碳减排的作用各不相同。本文将技术进步方式分为自主创新和技术引进,又将自主创新分为原始创新和模仿创新,以期通过更加细化的方式对技术进步与碳排放之间的关系进行更加深入的研究;本文还以环境规制成本作为门限变量,应用动态面板门限估计,研究环境规制的门限效应。研究结论表明:第一,原始创新不但没有降低碳排放,反而增加了碳排放,说明我国的技术创新更多地关注了产能的提升,绿色创新程度不高,创新间接效应大于直接效应,模仿创新对碳减排效果较好,其原因在于模仿创新是一种"跟随型"的创新;技术引进的作用很小,说明我国不可能通过购买的方式获得最适宜的技术。第二,在不同的地区,自主创新、模仿创新、技术引进对碳减排的作用表现出较大差异,因此促进技术进步以及减排政策制定不能采取"一刀切"。第三,原始创新、技术引进与碳减排之间均具有门限效应,当环境成本达到门槛值时,原始创新、技术引进开始促进碳减排。因此,需考虑不同技术进步路径的不同碳减排效应,选择不同的激励、扶持与规制政策。
[Abstract]:Technological progress is a fundamental measure to achieve carbon emission reduction, but different paths of technological progress-independent innovation and technology introduction, as well as different paths of technological progress in different countries and regions have different effects on carbon emission reduction. In this paper, the way of technological progress is divided into independent innovation and technology introduction, and independent innovation is divided into original innovation and imitation innovation, in order to study the relationship between technological progress and carbon emissions in a more detailed way. In this paper, the threshold effect of environmental regulation is studied by using dynamic panel threshold estimation with the cost of environmental regulation as threshold variable. The results show that: first, the original innovation not only did not reduce carbon emissions, but increased carbon emissions, indicating that China's technological innovation pays more attention to the improvement of production capacity, green innovation is not high, the indirect effect of innovation is greater than the direct effect. Imitation innovation has a good effect on carbon emission reduction, the reason is that imitation innovation is a kind of "follow type" innovation, and the effect of technology introduction is very small, which indicates that our country can not obtain the most suitable technology by purchasing. Secondly, in different regions, independent innovation, imitation innovation and technology introduction have different effects on carbon emission reduction, so the promotion of technological progress and the formulation of emission reduction policies cannot be "one-size-fits-all". Thirdly, original innovation, technology introduction and carbon emission reduction have threshold effect. When the environmental cost reaches the threshold, the original innovation and technology introduction begin to promote carbon emission reduction. Therefore, different carbon abatement effects of different technological progress paths should be considered, and different policies of encouragement, support and regulation should be chosen.
