摘要

探索技术创新对碳效率的影响,有利于实现更好的低碳转型,从而实现可持续发展目标。然而,对于技术创新对碳效率的影响,学术界仍然没有达成共识。中国幅员辽阔,不同地区的资源禀赋和经济发展存在差异。因此,本文首先通过中国30个省份的面板数据来评估中国的技术创新水平和碳排放效率。然后,利用PVAR(Panel Vector Autoregression)模型探讨了技术创新对碳排放效率影响的区域差异。研究结果表明:第一,我国技术创新水平呈持续发展趋势,但总体水平相对较低。西部地区的技术创新远远落后于东部地区。第二,中国的碳排放效率总体上处于较高水平,但呈现出由高到低的趋势。东部地区碳排放效率高于中部地区,中部地区碳排放率高于西部地区。第三,脉冲响应表明,中国技术创新对碳排放效率的影响经历了从负面影响到正面影响的转变。技术创新对碳排放效率的初始影响是负的,其中华中地区的负影响最大(−0.100),其次是东部地区(−0.050),最后是西部地区(−0.005),上述研究结果对中国不同地区因地制宜制定技术创新政策以提高碳排放效率具有启示意义。

How technological innovation influences carbon emission efficiency for sustainable development? Evidence from China

Exploring the impact of technological innovation on carbon efficiency is conducive to achieving a better low-carbon transition and thus reaching sustainable development goals. However, the academic community still has no consensus about the impact of technological innovation on carbon efficiency. China is a vast country with differences in resource endowment and economic development in different regions. Therefore, this paper first assesses the level of technological innovation and carbon emission efficiency in China through panel data of 30 provinces in China. Then, the PVAR (Panel Vector Autoregressive) model is utilized to explore the regional differences in the impact of technological innovation on carbon emission efficiency. The findings reveal that: First, the level of technological innovation in China shows a continuous development trend, but the level as a whole is relatively low. Technological innovation in western China is far behind that in eastern China. Second, China’s carbon emission efficiency is generally at a high level but shows a trend from rise to fall. The efficiency of carbon emission in eastern China is higher than in central China, and the efficiency of carbon emission in central China is higher than in western China. Third, the impulse response reveals that the influence of China’s technological innovation on the efficiency of carbon emission has experienced a change from negative impact to positive impact. The initial influence of technological innovation on carbon emission efficiency is negative, with the largest negative impact seen in central China (−0.100), followed by the eastern area of China (−0.050), and finally the western region of China (−0.005). After one period, technological innovation turned to have positive effect on the efficiency of carbon emission, with eastern China having the most positive impact (0.060), followed by central China (0.010), and western China ranking last (0.001). The above findings have implications for the formulation of technological innovation policies in different regions of China to improve the efficiency of carbon emissions in accordance with local conditions.
