摘要
The digitalization of industry has a significant impact on the low-carbon transformation and development in China,although the impact varies in different economic regions.Exploring the impact mechanism and path is beneficial for promoting the progress of China’s low-carbon economy.Based on the panel data of 30 provinces in China from 2011 to 2021,an indicator system was constructed to measure the comprehensive index of industrial digitalization and carbon emission intensity.A threshold regression model was used to explore the impact of industrial digitalization on regional carbon emission intensity from the perspectives of government intervention and regional economic development level.The results show that the digitalization of industries,which has been unequal in various regions of China,can significantly suppress the regional carbon emission intensity and promote the development of the low-carbon economy.Furthermore,the threshold model shows that the promoting effect of industrial digitalization on low-carbon economy development will be enhanced as the degree of government intervention increases;and the lower the level of regional economic development,the more obvious the promotional effect of industrial digitalization on the low-carbon economy.The findings of this study indicate that the uneven development level of digital industrialization hinders the low-carbon economy.In regions with different levels of economic development,the low-carbon effects of industrial digitalization vary significantly.Therefore,governments should strengthen the policy guidance of industry digitalization based on regional economic development status to enhance the promotional effect of industrial digitalization on the low-carbon economy.
工业数字化对中国经济低碳转型发展带来显著影响,但在不同经济区域的影响存在差异,探讨其影响机制与路径有利于促进中国低碳经济的进程。利用2011至2021年间中国30个省份的面板数据,构建指标体系测算工业数字化综合指数以及碳排放强度,并选取门槛回归模型,从政府干预程度和区域经济发展水平的角度探究工业数字化对区域碳排放强度的影响。研究发现:我国各区域工业数字化发展水平差异较大,但均能显著抑制区域碳排放强度,对低碳经济的发展具有明显的促进作用。进一步通过门槛效应模型研究发现,随着政府干预程度的增大,工业数字化对低碳经济发展的促进作用会增强;区域经济发展水平越低,工业数字化对低碳经济的促进作用越明显。研究认为,数字工业化发展水平的不平衡阻碍了低碳经济的发展,在不同经济发展水平的区域,工业数字化的低碳效应差异明显,各级政府应基于区域经济发展状况,强化行业数字化政策导向作用,以提升工业数字化对低碳经济的促进作用。
