Tracing the origin:Carbon emission effects of regional industrial dynamics
In recent years,global climate change and the problems it poses are becoming in-creasingly serious.Global warming caused by anthropogenic greenhouse gas emissions,particu-larly from industrial development,is a major challenge to human well-being,compared to the role of natural factors.The regional industrial structure and the dynamic carbon effect,under the goals of"carbon peaking and carbon neutrality",have become important issues.Based on the China Business Enterprise Registration Database and the CEADs Carbon Emission Data-base,this paper systematically analyzes the spatio-temporal evolution pattern and industry char-acteristics of regional carbon emissions in China from 2000 to 2019 based on a dynamic evolu-tionary perspective.It also empirically analyzes the carbon emission effects of regional industri-al dynamics,and further explores the regulatory mechanisms of cleanup and digital carbon re-duction pathways.The main findings are as follows.Firstly,China's carbon emissions have ex-perienced three stages in time:steady growth,rapid growth and structural transformation.Spa-tially,the regional carbon emissions have obvious spatial differentiation,showing a pattern of high in the north and low in the south,concentrated in large and medium-sized cities,particular-ly in developed heavy industry areas and several major urbanization and industrialization ag-glomerations.Industry characteristics are strongly correlated with the number of firm entries and incumbents in high carbon emission industries.Secondly,different factor-intensive indus-tries have heterogeneous carbon emission effects.The entry of capital-intensive and knowledge-intensive industries is beneficial for cities to reduce carbon emissions.Cities with comparative advantages in resource-intensive as well as labor-intensive industries may generate more car-bon emissions.Specifically,the entrants of industries,such as coal mining and washing and metal products,have significant positive impacts on the growth of regional carbon emissions.Thirdly,government-driven cleaner production and digital transformation can reduce the car-bon emission growth effect of industry dynamics,while the moderating effect is industry-het-erogeneous.Specifically,cleaner production promotes the carbon-reducing effect of capital-in-tensive business entry and weakens the carbon-increasing effect of resource-intensive industry entry.Overall,the research results contribute to an in-depth analysis of the potential carbon emission peaking paths in China's regions.And the results are of certain significance for the transformation and high-quality development of China's regional industries under the national target.
