摘要
为探讨工业企业数字化转型的节能减排效应,基于2015年~2021年13万余家工业企业大数据样本综合测度数字化转型水平,并运用固定面板模型和空间杜宾误差模型分析数字化转型水平对企业能源强度及其所在地区碳排放强度的影响.结果表明:(1)工业企业数字化转型水平每增加1%,对应能源强度降低1.907%,碳排放强度降低1.416%.(2)基于省级异质性的分组证明,各省、直辖市以及自治区之间存在明显的异质性.在数字化转型水平本身较高的地区、东部经济发达地区、资金及技术禀赋的直辖市以及数字化相关的试点地区,数字化转型水平对能源强度和碳排放强度的抑制作用明显较强.(3)数字化转型水平的节能减排作用有明显空间溢出效应.数字化转型水平对能源强度和碳排放强度的影响为负,且间接效应均大于直接效应.
To discuss the energy saving and emission reduction effects of industrial enterprises’digital transformation,the digital transformation level was comprehensively measured based on over 130000 big data samples of industrial enterprises from 2015 to 2021,and the fixed panel model and Spatial Durbin Error Model were used to analyze the impact of digital transformation level on the energy intensity and carbon emission intensity.The results indicated that:(1)The level of industrial enterprises’digital transformation increased 1%significantly reduced energy intensity and carbon emission intensity by 1.907%and 1.416%.(2)Provincial heterogeneity from grouped regression demonstrated the obvious heterogeneity among provinces,municipalities and autonomous regions.The level of digital transformation had a strong inhibitory effect on energy intensity and carbon emission intensity in some regions.For example,those with high digital transformation level and developed economic level,or Municipalities with capital and technology and pilot areas related to digitalization.(3)The role of digital transformation level in energy saving and emission reduction had a significant spatial spillover effect.The impact of digital transformation level on energy intensity and carbon emission intensity was negative,and the indirect effect was greater than the direct effect.
