长江经济带下数字经济赋能制造业绿色低碳转型升级路径研究
Research on the Path of Green and Low-Carbon Transformation and Upgrading of Manufacturing Industry Empowered by the Digital Economy under the Yangtze River Economic Belt

本文以长江经济带沿线11个省份的制造业为对象，计算其2013~2022年的碳排放量，设计长江经济带制造业绿色发展水平评价指标体系和数字经济发展水平评价指标体系，并运用熵权法确定各个指标的权重。在此基础上构建数字经济发展水平、制造业发展水平和碳排放量之间的调节效应模型，实证检验了数字经济发展、制造业发展与碳排放三者的关系。研究结果表明：2013~2022年长江经济带沿线11个省份的制造业呈良好发展态势，但碳排量总体上呈上升趋势，且两者存在正相关，但数字经济能够减弱和抑制这种正向关联，起到显著的调节作用。
This paper calculates the carbon emissions of the manufacturing industry in 11 provinces along the Yangtze River Economic Belt from 2013 to 2022, designs the evaluation index system of the green development level of the manufacturing industry and the evaluation index system of the development level of the digital economy in the Yangtze River Economic Belt, and uses the entropy weight method to determine the weight of each index. On this basis, a moderating effect model among the development level of the digital economy, the development level of the manufacturing industry and the carbon emission is constructed, and the relationship among the development of the digital economy, the development of the manufacturing industry and carbon emissions is empirically tested. The results show that from 2013 to 2022, the manufacturing industry in 11 provinces along the Yangtze River Economic Belt showed a good development trend, but the carbon emissions generally showed an upward trend, and there was a positive correlation between the two, but the digital economy could weaken and inhibit this positive correlation and play a significant moderating role.
