In recent years, global warming has attracted extensive attention. The main cause of global warming is the emission of greenhouse gases, known as carbon emissions. Therefore, it is of great significance to explore the influencing factors of carbon emissions and accurately predict carbon emissions for reducing carbon emissions and slowing down climate warming. This paper takes the carbon emissions of Shanxi Province in China as the research object. Firstly, the emission factor method is used to calculate the carbon emissions, and then the grey correlation model is used to screen out the factors that have a greater impact on carbon emissions (per capita GDP, urbanization rate, resident population, energy consumption, expenditure on R&D projects). Then, an improved grey multi-variable convolution integral model (AGMC(1, N)) is used to accurately predict carbon emissions. The results show that the application of the AGMC(1,N) model to carbon emission prediction has a good prediction effect. In addition, the carbon emissions of Shanxi Province will increase with the growth rate of per capita GDP, energy consumption, resident population, and expenditure on R&D projects, while the carbon emissions will gradually decrease with the increase of urbanization level. The prediction results provide the direction for carbon emission reduction in Shanxi Province. At the same time, theAGMC(1,N) model can also be applied to the prediction of carbon emissions in other provinces or other fields.
近年来,全球变暖受到了广泛关注。全球变暖的主要原因是温室气体的排放,通常被称为碳排放。因此,探索碳排放的影响因素并准确预测碳排放,对于减少碳排放、减缓气候变暖具有重要意义。本文以中国山西省的碳排放为研究对象。首先,采用排放因子法计算碳排放量,然后采用灰色关联模型筛选出对碳排放影响较大的因素(人均 GDP、城镇化率、常住人口、能源消耗、研发项目支出)。然后,采用改进的灰色多变量卷积积分模型(AGMC(1, N))对碳排放量进行精确预测。结果表明,AGMC(1, N)模型在碳排放量预测中的应用具有良好的预测效果。此外,山西省的碳排放量将随着人均 GDP、能源消耗、常住人口和研发项目支出的增长率而增加,而碳排放量将随着城镇化水平的提高而逐渐减少。预测结果为山西省的减排工作提供了方向。同时,AGMC(1, N)模型也可应用于其他省份或其他领域的碳排放量预测。
