平陆运河产业空间重组与港产城融合机制

Mechanisms of Industrial Spatial Restructuring and Port-Industry-City Integration of the Pinglu Canal

摘要: 在平陆运河通航条件逐步形成的背景下，本文围绕运输成本与市场可达性变化如何通过企业区位调整、产业链环节重组和区域节点功能分化，影响广西产业空间格局与港产城融合展开前瞻性分析。采用文献分析、逻辑演绎、区域节点比较和约束分析等方法，构建“通道条件改善–企业区位再评价–产业链空间重组–港产城融合–区域可持续发展”的条件性分析框架。研究表明，平陆运河的潜在经济效应并不会因通航而自然实现，其释放程度取决于稳定货源、集疏运衔接、产业承接能力、城市服务供给、跨区域协调及生态环境约束。南宁、钦州、横州、灵山及西江流域相关城市应结合区位基础与产业条件形成差异化节点分工，推动货物流动向本地价值创造转化。基于此，应以经济效率、社会包容和生态可持续性为评价导向，完善产业链协同与区域治理机制，降低同质化竞争和粗放开发风险。

Abstract: Against the backdrop of the gradual establishment of navigable conditions for the Pinglu Canal, this study conducts a prospective analysis of how changes in transportation costs and market accessibility may affect the industrial spatial pattern and port-industry-city integration in Guangxi through adjustments in firm location, the spatial reconfiguration of industrial-chain activities, and the functional differentiation of regional nodes. By applying literature review, logical deduction, regional node comparison, and constraint analysis, the study develops a conditional analytical framework of “improved corridor conditions - reassessment of firm location - spatial restructuring of industrial chains - port-industry-city integration - regional sustainable development”. The findings indicate that the potential economic effects of the Pinglu Canal will not be realized automatically upon navigation. Their realization depends on stable freight sources, efficient connections within the collection and distribution system, industrial carrying capacity, urban service provision, cross-regional coordination, and ecological constraints. Nanning, Qinzhou, Hengzhou, Lingshan, and relevant cities along the Xijiang River Basin should therefore establish differentiated functional roles based on their respective locational and industrial conditions, thereby transforming freight flows into local value creation. Accordingly, economic efficiency, social inclusion, and ecological sustainability should serve as the main evaluation criteria, while industrial-chain coordination and regional governance mechanisms should be improved to reduce the risks of homogeneous competition and extensive development.
