摘要
为剖析中国沿海三大国家级城市群之间及各城市群内部市级间在相似发达背景下进行远距离流动特征及形成缘由,基于百度LBS提供的流动截面数据及搜集的城市相关面板数据(2009—2018年),从城市经济、公共服务供给水平及创新力水平的视角探讨在经济水平同等发达的背景下,其人口进行跨城市群的远距离流动的形成机制。研究结果表明,在城市群网络密度方面:①城市出入度是城市集散能力的反映,大部分城市的出入度呈现正相关性;②整个城市群已呈现多中心均衡驱动格局,城市群内部呈现不同层次的均衡性结构,沿海城市群的整体网络密度较低,仅为0.356,三大城市群之间的联系程度并不高。在人口流动抉择方面:①经济收入差异在沿海城市间流动正向影响作用不显著;②城市公共服务供给水平有助于提高本市的人口吸引力,而且对周边城市产生整的空间外溢作用;③城市创新能力对城市接受大量流动人口促进作用并不大,甚至产生负向作用。最后,结合中国东部沿海城市群的实际情况,应从经济产业、公共服务水平及城市创新力等方面进行人口与城市合理发展的政策建议探寻。
At present,the population of many cities in China is gradually weathering.The characteristics and causes of long-distance flow among the three major national-level urban agglomerations along the coast of China and the municipalities in each urban agglomeration under similar developed backgrounds are analyzed based on Baidu LBS.From the perspective of urban economy,public service supply level,and innovation level,the flow cross-section data and the collected city-related panel data explore the formation mechanism of the long-distance flow of the population across urban agglomerations under the background of the same developed economic level.In terms of urban agglomeration network density,the results found that①The access degree is a reflection of the city’s ability to collect and distribute.The access degree of most cities is positively correlated.②The entire urban agglomeration shows a multi-center balanced driving pattern,with different levels within the urban agglomeration.The overall network density of the coastal urban agglomerations is relatively low,only 0.356.And the degree of connection among the three major urban agglomerations is not high.③The positive effect of economic income differences in the flow of coastal cities is not significant.The level of urban public service supply will help increase the city’s population attractiveness,and has a spatial spillover effect on surrounding cities.The ability of urban innovation to promote the city’s acceptance is not significant,and even has a negative effect.Finally,the research from the eastern coastal city clusters offers recommendations for the rational development of population and cities from the aspects of economy,industry,public service,and innovation capabilities.
