基于空间品质的经济地理核心——边缘模型研究

Economic geography core-periphery model based on qualities of space

随着经济从基于物质产品再生产向基于数据、信息、知识、智慧再生产的转变,聚焦于传统有形物质产品因素的克鲁格曼核心—边缘模型已无法系统解释中国经济活动空间集聚现象和人才区域迁移机制。本文基于新空间经济理论构建了包含空间品质及其溢价效应的核心—边缘模型,研究发现:①新空间经济学核心—边缘模型具有类突发性聚集、非对称维持点和完全自由贸易时空间并非无差异的新特征;②非农劳动力倾向空间品质更高的地区,且空间品质差距越大则流动趋势越明显;③缩小空间品质差距需要综合考虑各区域的便利设施水平以及区内和区际旅行成本等多方面因素。研究结果表明,未来促进区域高质量协调发展需要科学认识空间品质对经济活动空间区位的影响作用,需要把握缩小空间品质差距的理论逻辑和重视空间品质的区域一体化建设。

With the transformation of the economy from material product reproduction to data,information,knowledge,and intelligent reproduction,the Krugman Core-Periphery Model,which focuses on traditional tangible material product factors,is no longer able to systematically explain the phenomenon of spatial agglomeration of economic activities and the mechanism of talent regional migration in China.This article constructs a new core-periphery model based on the theory of new spatial economics,which includes qualities of space and its premium effect.The study finds that:Firstly,the new model has new characteristics such as quasi-burst aggregation,asymmetric maintenance points,and spatial differences in completely free trade;Secondly,non-agricultural labor tends to be in areas with higher qualities of space,and the larger the gap in qualities of space,the more obvious the trend of mobility;Thirdly,narrowing the gap in qualities of space requires comprehensive consideration of various factors such as the level of convenience facilities in each region and the cost of intra-regional and interregional travel.The research results indicate that promoting high-quality and coordinated regional development in the future requires a scientific understanding of the impact of qualities of space on the spatial location of economic activities.It is necessary to grasp the theoretical logic of narrowing the gap in qualities of space and attach importance to regional integration construction of qualities of space.
