新发展理念的提出,凸显了协同发展的重要性。京津冀协同发展,需要借力于产业的不断优化升级调整。本文构建了金融规模作用于产业升级调整的理论模型,揭示了金融规模对产业升级可能存在“促进”和“抑制”效应,进而采用京津冀1985—2015年面板数据,实证分析了金融规模对产业升级调整的内在影响机制。研究发现,金融规模对京津冀产业升级调整的总体效应为正;金融相关比和金融融资规模提高,会显著提升服务业生产率水平;金融集聚会促进工业生产率水平的提高;金融效率对工业生产率的影响为负,对服务业生产率的变化作用不明显,但对产业升级的总体效应为正。因此,应合理利用金融规模的“抑制”和“促进”效应,重视区域性金融政策可能带来的外部性,以继续深化市场经济体制改革,提高要素流动性,加快京津冀产业协同升级调整的步伐。
The proposal of new development concept highlights the importance of coordinated development. The coordinated development of Beijing, Tianjin and Hebei requires the continuous optimization and upgrading of industries. This paper constructs the theoretical model that the financial scale acts on the industrial upgrading and adjustment, and reveals that the financial scale may have the effect of “promoting” and “inhibiting” on the industrial upgrading, and then adopts the panel data of Beijing, Tianjin and Hebei in 1985-2015, The financial scale of the industrial upgrading of the inherent impact of the adjustment mechanism. The study found that the overall effect of financial scale on the industrial upgrading and adjustment of Beijing-Tianjin-Hebei region is positive; the increase of financial-related ratio and financial financing scale will significantly raise the productivity level of service industry; the financial gathering will promote the improvement of industrial productivity; the impact of financial efficiency on industrial productivity Of the negative impact on the service industry productivity change is not obvious, but the overall effect of industrial upgrading is positive. Therefore, we should make rational use of the “restraint” and “promotion” effects of the financial scale, pay attention to the possible externalities brought about by the regional financial policies, continue to deepen the reform of the market economic system, enhance the liquidity of elements and accelerate the economic development of Beijing, Tianjin and Hebei Industry coordination and upgrading of the pace of adjustment.
