京津冀协同发展作为国家为优化经济空间格局而重点实施的三大战略之一,承载着打造全国创新驱动经济增长新引擎和区域整体协同发展引领区的重要使命。京津冀三地经济金融总量大、产业互补性强,为实现区域协同发展奠定了良好的基础。随着京津冀协同发展的广度和深度日益拓展,三地自身产业结构持续优化,更进一步促进了区域经济发展整体性、协同性的提升。如何进一步促进京津冀产业结构优化调整,完善区域生产力布局和空间结构,成为推进京津冀协同发展的重要环节。本文针对京津冀产业结构比较优势,以企业集团合理布局作为产业结构调整的微观基础,通过引入HOV模型、集聚经济模型、引力模型,试图构建企业集团区域布局对区域产业结构调整影响传导机制三阶段模型,实现以企业集团所在地产业结构升级带动区域产业结构升级调整,并通过分析比较优势动态变迁对京津冀产业结构特别是首都产业结构的现实影响,研究京津冀产业结构调整的作用机制,以优化区域产业布局,构建首都“高精尖”经济结构,促进京津冀协同发展。
The coordinated development of Beijing, Tianjin and Hebei, as one of the three major strategies that the country has put in place to optimize the economic space, carries an important mission of building a new engine of national innovation-driven economic growth and a regional co-development lead. The three places of Beijing, Tianjin and Hebei have large total economic and financial resources and strong industrial complementation, laying a good foundation for the coordinated development of the region. As the breadth and depth of the coordinated development of Beijing, Tianjin and Hebei continue to expand, the industrial structure of the three regions continues to be optimized, further promoting the improvement of the integrity and synergy of regional economic development. How to further promote the optimization and adjustment of the industrial structure in Beijing, Tianjin and Hebei, and improve the layout and spatial structure of regional productive forces has become an important link in promoting the coordinated development of Beijing, Tianjin and Hebei. This paper aims at the comparative advantage of industrial structure in Beijing, Tianjin and Hebei, taking the rational distribution of enterprise groups as the micro-foundation of industrial restructuring. By introducing HOV model, agglomeration economic model and gravitation model, this paper tries to construct the transmission mechanism of regional industrial structure adjustment Stage model to achieve the upgrading of industrial structure in the location of enterprise groups to promote the adjustment and upgrading of regional industrial structure. By analyzing the comparative advantages of dynamic changes on the industrial structure of Beijing, Tianjin and especially the actual impact of the industrial structure of the capital, the mechanism of adjustment of industrial structure in Beijing, Tianjin and Hebei In order to optimize the regional industrial layout and construct the capital “high-tech” economic structure so as to promote the coordinated development of Beijing-Tianjin-Hebei region.
