京津冀供给侧改革分析与绿色政策建议

Analysis of Beijing-Tianjin-Hebei Supply-side Reform and Suggestions for the Green Policy

在梳理宏观经济增长理论逻辑的基础上,基于柯布—道格拉斯生产函数,生产外部性内部化、技术进步内生化,推演出适合当前经济发展阶段的京津冀生产函数,指出全要素生产率可内生解释为资本和人力的内外部产出效率,资本、人力与技术相互作用,在技术创新、信息化和人力资本的作用下可提高资本和人力产出效率。并基于京津冀生产函数进一步分析,指出提高全要素生产率是确保经济均衡增长,实现节能、减排和资源节约型生产的经济转型必由之路。最后提出京津冀供给侧改革的绿色政策建议。

By combing the theories of macro-economic growth and on the basis of Cobb-Douglas production function, the internalization of production externality and endogenization of technological progress, this research deduces the Beijing-Tianjin-Hebei production function suitable for current economic development, pointing out total factor productivity can be endogenously explained as internal and external output efficien- cy of capital and manpower; and capital, manpower and technology interact with each other. Affected by technological innovation, informatization and human capital, the output efficiency of capital and manpower can be improved. The further analysis based on the Beijing-Tianjin-Hebei production function indicates that improving total factor productivity is an essential way of guaranteeing economic growth and realizing eco- nomic transformation featuring saving energy and resources and reducing emissions. This paper finally offers some green policy suggestions for Beijing-Tianjin-Hebei supply-side reform.
