摘要基于2011—2019年中国243个城市的面板数据,从技术进步与结构转型视角实证检验了数字经济对城市节能减排的影响。研究发现,数字经济对节能减排的影响具有双重性,其在显著增加城市电力消耗和二氧化碳排放规模的同时也降低了电力消耗和二氧化碳排放的强度。机制检验表明,数字经济在推动绿色技术进步的同时也增加了城市电力消耗和二氧化碳排放规模,其原因在于绿色技术创新的能源回弹效应超过了绿色技术效率改善的节能效应。数字经济在推动产业结构转型的同时增加了城市电力消耗,但显著降低了二氧化碳的排放强度。其中,制造业结构转型具有减排效应,而农业和服务业由于产业结构低端化,其转型导致节能减排效果并不理想。异质性分析表明,良好的政府绿色数字化治理环境能够强化数字经济的节能减排效应。研究结论可为“双碳”目标下城市经济数字化转型及节能减排行动方略的制定带来启示。 Is the digital economy a“bonus”or a“minus”for cities to save energy and reduce emissions?This paper empirically tests the impact mechanism of the digital economy on urban energy saving and emission reduction from the perspective of technological progress and structural transformation using a panel data of 243 cities in China from 2011-2019.It is found that the digital economy is a“double-edged sword”for energy saving and emission reduction significantly increasing the scale of urban power consumption and CO_(2) emissions but reduces the intensity of power consumption and CO_(2) emissions.The mechanism test results show that the energy rebound effect of green technology innovation exceeds the energy-saving effect of green technology efficiency improvement.Therefore,the digital economy increases urban power consumption and CO_(2) emissions by promoting green technology progress.The digital economy increases urban power consumption by promoting the transformation of industrial structure,but significantly reduces the intensity of CO_(2) emissions.In detail,the structural transformation of the manufacturing industry has the effect of emission reduction,while energy saving and emission reduction effects of both agriculture and service industry are not significant due to the low-end industrial structure.In addition,a good environment of government green digital governance can strengthen the energy saving and emission reduction effects of the digital economy.The research conclusions can provide enlightenment for the digital transformation of urban economy and the formulation of energy saving and emission reduction strategies under the“dual carbon”goal.
