Abstract

Understanding the spatial differences and evolutionary characteristics of urban economy and exploring the impact of industrial agglomeration and industrial proximity on urban economic convergence are the bases for scientifically formulating policies for coordinated regional economic development. This study used QGIS 3.10.10 software and the Theil index to analyze the spatial distribution characteristics and regional disparities of urban economy. Then, a spatial econometric model was constructed to analyze the convergence and influencing factors of Guangdong’s urban economy. The results indicate that from 2006 to 2020, Guangdong’s urban economy grew rapidly and the degree of economic agglomeration gradually weakened, but its economic pattern always maintained the “Core-Edge” structural feature. The interval disparities between the Pearl River Delta Urban Agglomeration (PRD) and the edge area have always been greater than the intra-regional disparities, so they are main source of disparities in Guangdong. In Guangdong’s urban economy, σ-convergence and β-convergence coexist. The conditional β-convergence rate is 0.96~1.53%, and the half-life cycle is 45.4~72.36 years. Compared to the PRD, the economic disparities in the edge area are smaller but the convergence speed is faster and the half-life cycle is shorter. Both industrial agglomeration and industrial proximity have a significant impact on the economic convergence of Guangdong’s cities. Among them, industrial agglomeration has a positive impact, while industrial proximity has a negative impact. There is spatial heterogeneity in the impact of industries on economic development. Industrial agglomeration has a positive impact on the overall economic development of Guangdong, but it is not significant within the regions. Industrial proximity has significant negative externalities in the PRD region, and its impact is not significant in the edge area.

基于产业集聚与产业临近的广东城市经济空间差异与聚合研究

了解城市经济的空间差异和演化特征，探讨产业集聚和产业邻近对城市经济趋同的影响，是科学制定区域经济协调发展政策的基础。本研究利用 QGIS 3.10.10 软件和 Theil 指数分析了城市经济的空间分布特征和地区差异。然后，构建空间计量经济模型，分析广东城市经济的趋同性和影响因素。结果表明，2006-2020 年，广东城市经济快速增长，经济集聚程度逐渐减弱，但经济格局始终保持 "核心-边缘 "的结构特征。珠三角城市群与边缘地区的差距一直大于区域内差距，是广东差距的主要来源。在广东城市经济中，σ收敛与β收敛并存。条件β收敛率为0.96~1.53%，半衰期为45.4~72.36年。与珠三角相比，边缘地区的经济差距较小，但收敛速度较快，半衰期周期较短。产业集聚度和产业邻近度对广东城市经济趋同都有重要影响。其中，产业集聚度具有正向影响，而产业邻近度具有负向影响。产业对经济发展的影响存在空间异质性。产业集聚对广东整体经济发展有积极影响，但在区域内不显著。产业集聚在珠三角地区具有显著的负外部性，在边缘地区影响不显著。
