摘　　要：利用2004~2017年京津冀城市群和长江三角洲城市群地级以上城市的面板数据,在空间计量模型和引力模型的框架下,比较分析两大城市群中心城市北京和上海对周围城市辐射性质和辐射强度的差异。研究表明:北京、上海的辐射性质分别表现为极化效应和扩散效应,北京对周围城市的极化效应要远高于上海对周围城市的扩散效应,极化效应一旦形成具有很强的路径依赖;辐射强度平均水平为较强影响和强影响,但二者在具体测评数值方面差距显著。同时,中心城市扩散效应越强、产业分工越明显,经济影响强度就越大;地理距离仍然是中心城市影响力大小的关键因素,尤其是以极化效应为主导的中心城市,相邻城市仍然能够受到较强的经济辐射。This article uses panel data for cities above prefecture level of the Beijing-Tianjin-Hebei urban agglomeration and the Yangtze River Delta urban agglomeration from 2004 to 2017. Under the framework of spatial metrology model and gravitational model, the article compares and analyzes the difference between the radiation properties and radiation intensity of Beijing and Shanghai to the urrounding cities.Studies have shown that the radiation properties of Beijing and Shanghai respectively exhibit polarization effects and diffusion effects. The polarization effect of Beijing on surrounding cities is much higher than the diffusion effect of Shanghai on surrounding cities. Once the polarization effect is formed, it has a strong path dependence. The average level of radiation intensity is relatively strong and strong, but there is a significant gap between the two in terms of specific evaluation values.The stronger the diffusion effect of the central city and the more obvious the industrial division of labor, the intensity of economic impact is the greater. Geographical distance is still a key factor in the influence of the central city, especially in the central city that is dominated by polarization effects. The neighboring cities can still receive strong economic radiation.
