金融能级与城市产业创新竞争力:城域分化与耦合协同

Financial Integration Level and Urban Industrial Innovation Competitiveness: Urban Differentiation and Coupling Coordination

城市产业创新竞争力与所在区域的金融能级水平密切相关。文章利用2012—2019年289个地级市数据,就金融能级扩容对城市产业创新竞争力作用机制、城域差异及耦合匹配等问题展开深入讨论。研究发现:(1)金融能级扩容能显著提升城市产业创新竞争力,且金融能级的规模广度和效率效度的赋能优势要显著优于结构深度。(2)金融能级通过降低城市主体平均融资成本、促进城市产业主体活力、优化城市金融服务创新能力来驱动城市产业创新竞争力的提升。(3)不同功能定位及产业基础的城市金融能级对其产业创新竞争力的影响存在显著的城域分化及空间溢出效应,各城市金融能级与产业创新竞争力之间的耦合协调度均呈现提升趋势,国家级重点城市群内的城市在金融能级和产业创新竞争力方面的耦合协同度明显优于其他区域。

The efficient matching of urban finance and industrial innovation is not only a necessary path for financial returning to serve the real economy, but also a core starting point for comprehensively improving the competitiveness of industrial innovation with city as the carrier. This paper aims to explore the relationship between the overall financial integration level and urban industrial innovation competitiveness, comprehensively design the financial integration level index from the dimensions of financial scale breadth, structural depth, and efficiency validity, and investigate the enhancement effect and mechanism, regional differentiation characteristics, and coupling coordination degree of financial integration level on urban industrial innovation competitiveness.The results show that: First, financial integration level has a significantly stronger promoting effect on urban industrial innovation competitiveness than a single factor. Compared to structural depth, the empowerment advantages of scale breadth and efficiency validity are superior. Second, the upgrading of financial integration level can drive the improvement of urban industrial innovation competitiveness by reducing the average financing cost of enterprises, promoting the vitality of urban market entities, and optimizing the innovation ability of urban financial services. Moreover, there are obvious regional differentiation characteristics. Third,the development of financial integration level in surrounding areas is very important to the radiation effect of urban industrial innovation competitiveness, but there is a certain time lag effect. Fourth, the coupling coordination degree between financial integration level and industrial innovation competitiveness of each city gradually increases, showing a characteristic of “scale coupling efficiency coupling structural coupling”. Cities within national key urban clusters have a higher coupling coordination degree than other regions.The contributions of this paper are as follows:(1) It constructs the financial integration level index, transforming the indicator from the single factor to the multi-dimensional factor, and conducts an in-depth study on the impact and mechanism of financial integration level on urban industrial innovation competitiveness.(2) It further measures and compares the coupling coordination degree between financial integration level and urban industrial innovation competitiveness, which is an innovative theoretical exploration for implementing the important viewpoint that “high-quality development is the primary task of comprehensively building a modern socialist country”.(3) Considering the differential impact that the unique attributes of cities may have on financial integration level empowering urban industrial innovation competitiveness, it further conducts analysis on regional convergence and differentiation, which provides targeted reference for formulating the coordinated development path of localized financial integration construction and urban industrial innovation competitiveness.
