哈长城市群网络空间结构的层级特征与网络结构优化对策

随着科学技术的不断发展,经济全球化、信息现代化和便利的交通使得城市与城市之间联系更加紧密,各种要素在城市间不断循环和流动,城市规模逐步开始扩大,城市群成为区域发展的重要力量。本文将哈长城市群11个地级市作为主要研究对象,基于交通流、经济流和信息流等三种流数据,同时结合城市联系强度方法构建交通流网络、经济流网络、信息联系网络和综合联系网络。通过多元流强度分析哈长城市群城市层级体系,绘制不同层级体系下城市网络的空间关联格局,深入剖析多元流视角下的哈长城市群城市网络层级结构;提出有效的优化策略,以促进该地区的一体化发展。With the continuous development of science and technology, economic globalization, information modernization and convenient transportation have made the connection between cities more close, various elements continue to circulate and flow between cities, the scale of cities has gradually begun to expand, and urban agglomerations have become an important force for regional development. In this paper, 11 prefecture-level cities in the Harbin-Changchun urban agglomeration are taken as the main research objects, and based on the three types of flow data, such as traffic flow, economic flow and information flow, combined with the urban connection intensity method, the traffic flow network, the economic flow network, the information connection network and the comprehensive connection network are constructed. Through the analysis of the urban hierarchy of the Harbin-Changchun urban agglomeration through the multi-flow intensity, the spatial correlation pattern of the urban network under different hierarchical systems is drawn, and the hierarchical structure of the urban network of the Harbin-Changchun urban agglomeration from the perspective of multiple flows is deeply analyzed. Propose effective optimization strategies to promote the integrated development of the region.

劳动力配置效率的城市层级特征及空间收敛演进

文章构建一般均衡模型识别劳动力配置效率,利用ArcGIS分析工具、莫兰指数、Getis-Ord G_(i)^(*)统计模型、空间收敛模型等方法并结合2011-2018年全国流动人口动态监测调查数据探究城市劳动力配置效率的时空分异特征、城市层级特征、空间收敛性及其动态演进特征。结果表明:①城市劳动力配置效率表现为先上升后下降的倒“U”型趋势特征,但总体效率水平相比初期有较大改善。②城市劳动力配置效率的时空演化呈现出三重特征,即以省会城市为核心的城市群明显高于非城市群,东南沿海城市明显高于西北内陆城市,劳动力配置效率中高水平城市表现为先扩大后收缩的态势。③城市劳动力配置效率具有明显的层级特征,即按城市规模等级、行政等级逐级递减。④城市劳动力配置效率存在空间收敛性,即以不同的增长路径收敛至稳态水平,且政府财政支出、产业结构及环境规制等因素会促进劳动力配置效率收敛。③城市劳动力配置效率收敛速度会随着时间推移而逐步衰减,受各类因素的影响效应也随之呈现不同程度的变化。
