Abstract

China's digital industry (DI) is vital in curbing carbon intensity. We constructed the mechanism of the DI on carbon intensity through energy structure and efficiency. We divided the development level of the DI into two perspectives: scale and efficiency. Based on industrial and regional differences, we empirically tested the influence of China’s DI on carbon intensity through energy structure and efficiency. Our findings revealed that the role of the DI’s scale surpassed its efficiency in curbing carbon intensity in China. Further, the DI’s scale and efficiency significantly inhibited carbon intensity by improving energy efficiency; however, their inhibitory effect through optimising energy structure was limited. Moreover, the inhibitory effect of the DI on carbon intensity varied among industries and regions. Finally, we proposed measures to reduce carbon intensity when developing the DI.

从规模和效率角度看中国数字经济对碳排放的影响

中国的数字产业（DI）对抑制碳强度至关重要。我们通过能源结构和效率构建了数字产业对碳强度的影响机制。我们将数字产业的发展水平分为规模和效率两个视角。基于产业和地区差异，我们实证检验了中国直接投资通过能源结构和效率对碳强度的影响。我们的研究结果表明，在抑制中国碳强度方面，直接投资规模的作用超过了其效率。此外，直接投资规模和效率通过提高能源效率对碳强度有明显抑制作用，但通过优化能源结构的抑制作用有限。此外，直接投资对碳强度的抑制作用因行业和地区而异。最后，我们提出了在发展直接投资时降低碳强度的措施。

期刊介绍： Environment, Development and Sustainability is an international and multidisciplinary journal covering all aspects of the environmental impacts of socio-economic development. It is also concerned with the complex interactions which occur between development and environment, and its purpose is to seek ways and means for achieving sustainability in all human activities aimed at such development. The subject matter of the journal includes the following and related issues: -mutual interactions among society, development and environment, and their implications for sustainable development -technical, economic, ethical and philosophical aspects of sustainable development -global sustainability - the obstacles and ways in which they could be overcome -local and regional sustainability initiatives, their practical implementation, and relevance for use in a wider context -development and application of indicators of sustainability -development, verification, implementation and monitoring of policies for sustainable development -sustainable use of land, water, energy and biological resources in development -impacts of agriculture and forestry activities on soil and aquatic ecosystems and biodiversity -effects of energy use and global climate change on development and sustainability -impacts of population growth and human activities on food and other essential resources for development -role of national and international agencies, and of international aid and trade arrangements in sustainable development -social and cultural contexts of sustainable development -role of education and public awareness in sustainable development -role of political and economic instruments in sustainable development -shortcomings of sustainable development and its alternatives.
