西安市工业产业碳排放驱动因素分析及碳达峰情景预测

Analysis of Industrial Carbon Emission Driving Factors and Prediction of Carbon Peak in Xi' an

西安市作为西部地区的核心城市和我国工业基础重要来源, 分析其工业产业碳排放驱动因素及碳达峰预测对我国可持续发展至关重要。本研究利用LMDI方法对西安市工业二氧化碳排放的影响因素进行分解, 然后采用岭回归法和STIRPAT模型分析四大驱动因素对碳排放的定量影响, 最后采用情景分析法预测了未来15年三种不同发展情景下的西安市工业产业碳排放情况和碳达峰时间。研究发现:

(1) 2013—2022年西安市工业碳排放总量呈负增长, 其中能源强度与能源结构负效应显著, 贡献率分别为376. 92%和210. 95%, 而经济发展和人口规模表现为碳排放增量的正效应, 贡献率分 别为-288. 64%和-199. 24%。

(2) 2023—2040年, 西安市工业碳排放预计先上升后下降, 主要受人口规模影响, 弹性因子1. 735。

(3) 低碳和基准发展情景有助于西安市工业提前完成碳达峰目标, 但高碳模式在2040年都难以实现碳达峰。基准情景是西安市工业发展最佳模式, 预计2028年碳达峰, 峰值4941. 89万吨。

本研究可为开发西安市工业产业合理的碳达峰形成路径提供理论依据, 并帮助决策者制定相应的高质量发展路径。 

As a key region in the western region and an important source of China' s industrial foundation, analyzing the driving factors of industrial carbon emissions and predicting carbon peak in Xi' an is crucial for China' s sustainable development. . This study employed the Logarithmic Mean Divisia Index (LMDI) method to decompose the influencing factors of industrial carbon emissions in Xi’an. Then, the ridge regression method and the Stochastic Impacts by Regression on STIRPAT model was used to analyze the quantitative impact of four driving factors on industrial carbon emissions. Finally, scenario analysis was adopted to predict the carbon emissions and carbon peaking time of Xi' an' s industrial sector under three different development scenarios in the next 15 years. The study found that:

(1) From 2013 to 2022, the total industrial carbon emissions in Xi' an exhibited aa negative growth. energy intensity and energy structure exhibited significant negative effects, with contribution rates of 376. 92% and 210. 95%, respectively. In contrast, economic development and population size factors played a positive effects on carbon emission increments, with contribution rates of-288. 64% and-199. 24% respectively.

(2) From 2023 to 2040, the predicted total industrial carbon emissions in Xi' an primarily showed a trend of first rising and then declining, which primarily influenced by population size, with an elasticity factor of 1. 735.

(3) Both low-carbon and benchmark development scenarios could help Xi' an' s industrial sector achieve its carbon peaking target earlier, but a high-carbon model would struggle to reach carbon peaking even by 2040. The baseline scenario represented the optimal development model for Xi' an, with carbon peaking projected to occur in 2028, reaching a peak of 49. 4189 million tons.

This study provided a theoretical basis for developing a reasonable carbon peaking pathway for Xi' an' s industrial sector and assisted the government in formulating corresponding high-quality development paths.
