摘要: 本文基于2000—2023年中国省际分行业数据,通过扩展Feder模型并融合机器学习与面板回归方法,系统考察了工业与服务业对经济增长的差异化贡献及其作用机制。研究发现,工业通过技术进步和产业关联效应成为经济增长的重要驱动力;服务业在经济增长中发挥着不可替代的作用,特别是金融业通过与工业的协同发展能够显著促进经济增长,而脱离实体经济的金融扩张则可能对经济增长产生抑制作用。本文还揭示了工业发展存在非线性特征,其边际贡献在跨越特定阈值后显著提升。基于实证结果,本文建议产业政策应统筹工业与服务业协同发展以优化资源配置效率,以及金融业需强化服务实体经济功能,促进产业良性互动。本研究为推动产业结构优化升级、实现经济高质量发展提供了理论与实证依据。

Abstract: Based on inter-provincial industry data from 2000 to 2023 in China, this study systematically examines the differential contributions and mechanisms of industry and services to economic growth by extending the Feder model and integrating machine learning with panel regression methods. The findings reveal that industry serves as a key driver of economic growth through technological progress and industrial linkage effects, while services play an indispensable role, particularly in the financial sector, whose synergistic development with industry significantly enhances economic growth efficiency. Conversely, financial expansion decoupled from the real economy may inhibit economic growth. Further analysis uncovers a nonlinear characteristic in industrial development, where marginal contributions increase markedly after going across the specific threshold. Based on empirical results, this study recommends that industrial policies prioritize coordinated development between industry and services to optimize resource allocation efficiency, and that the financial sector strengthen its function in serving the real economy to foster positive industrial interactions. The research provides theoretical and empirical foundations for promoting industrial structure upgrading and achieving high-quality economic development.
