By utilizing the Cobb-Douglas function for fitting, it selects fossil energy input, total fixed capital formation, labor input, and gross domestic product (GDP) in Beijing from 2010 to 2022 as the analytical objects. It preliminarily explores the factors influencing economic growth in Beijing, analyzes its marginal rate of technical substitution, marginal output, marginal elasticity, and technological progress coefficient, and provides corresponding analysis and elaboration of the results. Furthermore, it offers suggestions for Beijing’s future economic development and energy strategy. The paper concludes that from 2010 to 2022, Beijing’s economic growth was primarily driven by high consumption of fossil energy and substantial fixed capital investment, which is closely related to its high energy demand, accelerated urbanization process, and the development of capital-intensive industries. In contrast, the labor contribution was relatively small. Affected by population aging and the transformation of the industrial structure towards technology and capital-intensive sectors, Beijing needs to optimize its industrial structure, improve energy efficiency, strengthen technological innovation and talent cultivation, and pursue more sustainable economic growth.展开更多
