【摘要】：低碳技术创新被视为解决全球气候变暖问题的最关键工具之一,然而其碳强度抑制效应及影响机理却较少获得实证经验支持。本文基于全球专利数据库,利用专利统计方法,测算1992-2012年全球15个经济体的低碳技术创新水平。事实特征分析发现,低碳技术创新水平、能源使用结构和碳强度在演变规律上存在密切联系。本文进一步提出理论假设,利用中介效应模型实证探讨低碳技术创新的碳强度影响机理。实证结果表明:(1)无论是低碳技术创新,还是细分的清洁技术创新和灰色技术创新,都具有直接且显著的碳强度抑制效应;(2)低碳技术创新和能源使用结构皆为碳强度变化的关键影响因素,且低碳技术创新能够以提升清洁能源使用比例为中介渠道,发挥显著的碳强度间接抑制效应。
[Abstract]:Low-carbon technology innovation is regarded as one of the most important tools to solve the problem of global warming, but its carbon intensity inhibition effect and its influence mechanism are seldom supported by empirical experience. Based on the global patent database, this paper calculates the low carbon technological innovation level of 15 economies in the world from 1992 to 2012 by using the patent statistics method. It is found that the level of low-carbon technology innovation, energy use structure and carbon intensity are closely related to each other. In this paper, the theoretical hypothesis is put forward, and the mechanism of carbon intensity influence of low-carbon technological innovation is discussed empirically by using intermediary effect model. The empirical results show that: (1) whether low-carbon technology innovation, or subdivision of clean technology innovation and grey technology innovation, Both have direct and significant carbon intensity inhibition effects. (2) Low-carbon technology innovation and energy use structure are the key factors of carbon intensity change, and low-carbon technology innovation can be mediated by increasing the proportion of clean energy use. Exerting significant indirect inhibition effect of carbon intensity.
