摘要
依据中心城市和受辐射城市并构建测度指标体系,引入城市间距离对分形模型进行改进,对我国三大都市圈中心城市的经济辐射力进行客观、全面的分析比较。研究发现:上海对半径300 km范围的辐射力与北京对半径200 km范围的辐射力相当,而广州对半径200 km范围的辐射力相对较差;3个中心城市行政地位差别很大,但政策支持力度对辐射力的影响与其他影响因素相比并无明显优势;金融业发展是辐射力最重要的影响因素,辐射力对城市货运能力和客运能力的依赖度有明显差异。
Considering both central city and other cities being radiated to construct the measurement index system with the inverse square of distances between cities as the weighted index system to improve the fractal model,this paper analyzed the economic radiation power of the three central cities of the metropolitan area from China objectively and comprehensively. The study found that Shanghai＇s radiation power to a circle with radius of 300 km is almost the same to Beijing＇s radiation power to a circle with radius of 200 km,but Guangzhou＇s radiation power to a circle with radius of 200 km is relatively poor; The three central cities have different administrative status,but there is no obvious advantage of policy support comparing with other influencing factors; Financial industry development is the most important factor influencing the radiation power,and the radiation powers have obvious different dependence on cargo capacity and passenger capacity of the city.
