摘要
在全球气候持续变暖、生态环境问题日益严峻的当下,碳减排成为与全人类息息相关的问题.基于中国2006-2019年省级面板数据建立空间杜宾模型(SDM)研究技术创新对碳减排的空间效应,研究结果表明:一个城市技术创新能力的提升不仅对本地区碳减排有显著正向影响,对相邻地区的碳减排也有影响,存在空间溢出效应;同时,这种溢出效应在东部、中部、西部有明显的异质性,东部最强,中部次之,西部地区较弱.因此聚焦技术创新,完善政府市场的协调机制,因地制宜地发挥技术创新的空间溢出效应,探索碳减排新思路,以推动我国的低碳经济增长.
Abstract
In the context of continuous global warming and increasingly severe ecological and environ-mental issues,carbon emission reduction has become an issue closely related to all humanity.Based on China's inter-provincial panel data from 2006 to 2019,this paper establishes a Spatial Durbin Model(SDM)to study the spatial effects of technological innovation on carbon emission reduction.The re-sults show that the improvement of a city's technological innovation capacity not only exerts a signifi-cant positive impact on carbon emission reduction in its own region,but also has an impact on carbon emission reduction in neighboring regions,with spatial spillover effects.At the same time,the spillo-ver effect exhibits significant heterogeneity in the eastern,central,and western regions respectively,with the eastern region being the strongest,followed by the central region,and the western region be-ing comparatively weaker.Therefore,focusing on technological innovation,improving the coordina-tion mechanism between the government and the market,giving full play to the spatial spillover effect of technological innovation according to local conditions,and exploring new ideas of carbon emission reduction can promote China's low-carbon economic growth.
