北京和上海分别作为长三角、京津冀经济圈的核心城市,近年来对两大城市经济辐射作用的争议日益突出。通过统计数据分析,得出上海对长三角的经济辐射作用强于北京对京津冀的辐射作用。对此结果从地理位置、产业结构等方面进行了解释,并在此基础上提出政策建议。 As the core cities of the Yangtze River Delta and Beijing-Tianjin-Hebei economic circle, Beijing and Shanghai, respectively, have become increasingly controversial over the economic radiation of the two major cities in recent years. Through the statistical analysis, it is concluded that the economic radiation effect of Shanghai on the Yangtze River Delta is stronger than that of Beijing on Beijing-Tianjin-Hebei.
