摘要

鉴于当前地域分工实践已转向依托产业链供应链的新型分工形式,相关研究仍侧重于生产性服务业与制造业的差异度量,制约了城际分工政策的优化更新。以我国12个城市群为研究单元,结合2009—2022年上市公司供应链数据,从上下游联系视角揭示了城市群功能分工格局,实证检验了功能分工模式对城市群经济绩效的影响。研究发现,非集中化的上下游分工模式有助于城市群经济绩效的提升,其作用机制在于多元化城市参与分工所带来的供应链生产要素配置的优化和上下游市场互借规模的扩大。相关多样化在功能分工影响城市群经济绩效的过程中起到正向调节作用,相同产业门类的上下游企业联系增强了非集中化分工模式的经济绩效。城市群经济基础和一体化水平是影响分工绩效的重要因素,非集中化分工模式对沿海城市群和优化提升型城市群经济绩效的促进作用分别大于内陆城市群和发展壮大型城市群。研究结论有助于丰富功能分工在联系维度的理论内涵,并为城市群区域一体化提供政策启示。

Abstract

Given that current regional division practices have shifted toward new forms based on industrial and supply chains, relevant studies remain focused on measuring disparities between producer services and manufacturing sectors, which restricts the optimization and updating of inter-city division policies. Taking 12 China’s urban agglomerations as research units and using supply chain data from listed companies (2009-2022), this paper unveils the spatial patterns of functional division within urban agglomerations from the perspective of upstream-downstream relationships and empirically examines its impact on economic performance. The main findings are as follows: Firstly, a decentralized upstream-downstream division significantly enhances the economic performance of urban agglomerations. This effect operates through the optimized allocation of supply chain factors derived from diversified cities participation and the expansion of borrowed market size. Secondly, related variety positively moderates the relationship between functional division and economic performance, indicating that urban agglomerations benefit more economically from inter-city relations among upstream and downstream companies within the same industrial sectors. Thirdly, the economic impact of functional division exhibits heterogeneity across urban agglomerations, with stronger effects observed in coastal and “optimization-upgrading” urban agglomerations compared to inland and “development-growth” urban agglomerations. This underscores the pivotal role of economic foundations and integration levels in shaping division outcomes. This study enriches the theoretical understanding of functional division from a relationship perspective and offers policy implications for regional integration within urban agglomerations.
