城市群驱动产业整合与全球价值链攀升研究——以长三角地区为例

Industrial Integration Driven by Urban Agglomeration and the Rising of the Global Value Chain: A Case Study of the Yangtze River Delta

形成具有全球影响力城市群的过程,本质上就是特定地区通过提升全球价值链上的高度,建设超级产业集群的过程。长三角经过近三十年的一体化发展,已逐渐形成了全球性城市群的雏形,但对比发达国家发展成熟的城市群,长三角城市群在产业发展与全球价值链高度的提升上还有较大的拓展空间,这也成为长三角城市群产业与区域发展的焦点之一。目前,长三角城市群整体产业专业化程度较高,但囿于产业发展的地区性差异,长三角南北两翼次级城市群之间在全球价值链上仍存在一定的级差,未能完全发挥出城市群应有的规模效应与网络效应。这种级差与较高的产业相似性也为长三角次级城市群之间的产业整合与实现全球价值链攀升提供了源动力。因此,在长三角高质量一体化发展的大背景下,长三角南北两翼次级城市群应充分利用都市圈建设的机遇,通过产业内部的区域间分工,以局地一体化带动全局一体化,进一步巩固与深化长三角城市群的产业优势与区域优势。

The process of forming global urban agglomeration is essentially a process in which a region builds a super industry cluster by improving the status of the global value chain. After nearly 30 years of integrated development, the Yangtze River Delta has gradually formed the prototype of global urban agglomeration. However,compared with the mature corresponding ones,it still needs improvements. At present,the overall degree of specification in the Yangtze River Delta Urban Agglomeration( YRDUA) is relatively high,but due to the regional industrial development differentiation,there is level difference in the global value chain between the north and south wings of the YRDUA,which fails to fully exert the scale effect and network effect that the urban agglomeration should have. This level difference and high industrial similarity also provide the driving force for industrial integration between the sub-megalopolis in the YRDUA. Therefore,in the context of the high-quality integrated development of the YRDUA,the sub-megalopolis such as the north and south wings of the YRDUA should take advantage of the opportunity of the construction of the metropolitan area. Through the intra-region specification within the industry,local integration will be used to promote global integration,furthermore,it will consolidate and deepen the industrial and regional advantages of the YRDUA.
