Abstract

Balancing economic growth with carbon emission control requires the coordination of policy preferences for economic and carbon reduction goals, as well as the low-carbon transformation of industrial and ownership structures. This study employs a multi-objective input-output optimization model to investigate the trade-offs among maximizing GDP growth, minimizing carbon emissions, and minimizing energy consumption within the planning period of 2017-2035 in China. The model accounts for the heterogeneity of industrial structures and ownership attributes, examining both national aggregates and the adjustment paths and ownership trends across different provinces. The findings reveal: (1) Sectors with high output and low energy consumption are growing, while high pollution and high energy-consuming sectors are declining, driven primarily by technological levels, followed by policy and development preferences. (2) Domestic capital expanding into high technology and capital-intensive sectors, HMT capital favoring the economically developed high technology regions, and foreign investment declining. (3) Regional adjustment in high-value or high-energy-consumption sectors are more pronounced in central and western provinces and less economically developed regions, while industries that are neither high-energy-consumption nor high-value show greater increases in resource-rich provinces with better infrastructure.

中国省际碳减排的多目标优化方法:考虑产业结构和所有权属性。
平衡经济增长和碳排放控制需要协调经济和碳减排目标的政策偏好,以及产业结构和所有制结构的低碳转型。本文采用多目标投入产出优化模型,考察了2017-2035年中国GDP增长最大化、碳排放最小化和能源消耗最小化三者之间的权衡关系。该模型考虑了产业结构和所有制属性的异质性,既考察了全国总量,也考察了不同省份的调整路径和所有制趋势。研究结果表明:①高产出、低能耗行业呈现增长趋势,高污染、高能耗行业呈现下降趋势,主要受技术水平驱动,其次受政策和发展偏好驱动;(2)国内资本向高技术和资本密集型行业扩张,HMT资本向经济发达的高技术地区倾斜,外商投资减少。③高附加值、高能耗行业的区域调整在中西部省份和经济欠发达地区更为明显,而在资源丰富、基础设施较好的省份,非高能耗、非高附加值行业的增长幅度更大。
