摘要
借助引力模型和社会网络分析方法(SNA),对浙江省67个县市的空间联系及构成的经济联系网络进行实证分析和研究。研究结果表明:2005—2015年,浙江省县际经济联系强度经历了由低水平的稳定波动阶段向较高水平的快速增长阶段的转变,经济联系首选地的选择由邻近地域指向逐渐转为中心城市指向和交通可达性指向;浙江省网络结构逐渐趋于复杂,已基本形成了多中心驱动的经济联系网络格局,网络整体较为松散但网络密度在逐渐增强;中心城市间的经济联系密切但具有明显的不均衡性,杭州、宁波一直是浙江省主要的辐射源和扩散点,但这一核心地位正受到发达县域的挑战;经济联系强弱与自然条件优劣及经济发展程度相吻合,表现出明显的"东北-西南"地域分异特征。
Based on the gravity model and the method of social network analysis(SNA), this paper makes an empirical analysis and research on the spatial relation and the economic linkage network of 67 counties and cities in Zhejiang Province. The results show that in 2005-2015, the intensity of economic linkages between counties and cities in Zhejiang Province has changed from a low level of stable fluctuation to a high level of rapid growth and the choice of the preferred location for economic ties gradually turns from the orientation of neighboring regions to the orientation of central cities and transportation accessibility. The network structure of Zhejiang Province is becoming more and more complex, which has basically formed the pattern of economic linkage network driven by multiple centers. The economic linkages between the central cities are close, but there is obvious imbalance. Hangzhou and Ningbo have always been the main radiation source and diffusion point of Zhejiang Province. However, this core position is being challenged by developed counties. The strength of economic linkages is consistent with the natural conditions and the degree of economic development.
