Lively Lands: The Spatial Reproduction Squeeze and the Failure of the Urban Imaginary

This article argues that the theoretical invisibility of non-privatized land tenures constitutes a failure of the urban imaginary, which restricts the ability to forge less commodified urban futures. The article explicates two attributes of non-privatized land—fungibility and combinatoriality—that produce an urban land nexus capable of fostering pro-poor agglomeration economies and generating socialities that exceed the model of the separative self that is hegemonic in more propertied settings. Fungibility, it shows, externalizes supportive economies of production and reproduction into surrounding neighborhoods by shifting the boundaries and terms of usufruct without cadastral oversight or regulation. Combinatoriality—a hybrid formulation of combined territories and combined territorialities—describes overlapping forms of access to land or demarcations of legitimate land use, either competitive or reciprocal. Together, these two attributes of non-privatized land systems produce a propinquity requirement for economic production, or a social density and liveliness more limited in privatized land markets. Through a diagnostic analogy with the simple reproduction squeeze characteristic of subsistence agrarian settings, it charts how an urban spatial reproduction squeeze—felt globally in dense, rising-rent environments across the global North and South—generates subsistence needs that mixed-tenure environments are uniquely capable of fulfilling and that can provide inspiration for radical housing struggles elsewhere.     

开发区与城市空间结构演化——以兰州市为例

以兰州城市开发区为例,在对其发展阶段进行系统梳理和客观划分的基础上,分别从城市形态、新城建设、人口结构、文化结构和社会分异等方面,较为系统地探讨了开发区对城市空间结构演化所产生的影响,以期对兰州城市开发区的健康持续发展及城市的合理规划和有序建设提供决策参考。     

基于时序遥感影像的城市规模扩张研究——以重庆主城为例

本文通过对城市规模的概念介绍,以及检测城市规模使用的技术方法,本文主要是利用1988,1996,2001,2007四年的TM时序遥感影像,对重庆主城区的城市规模扩展进行了监测,分析了自1988-2007年该区域用地规模的动态变化过程及时空特征。同时还对重庆城市用地的规模检测的结果进行了评价。评价结果表明,近二十年来,重庆主城区城市规模扩展迅速,并先后经历了"向西扩展"和"向北扩张"的两个阶段。     

国家审计推进经济高质量发展的作用研究——基于地级城市面板数据的空间计量分析

采用空间杜宾模型和2006—2016年我国283个地级及以上城市的面板数据,探讨了国家审计对城市经济发展质量的影响及其空间效应。结果表明,国家审计能显著提升本地区经济发展质量,但对周边地区产生了负向空间外溢效应;国家审计对本地和周边地区经济发展质量的影响是对动能转换、结构升级、发展效率、节能减排、成果分享五个方面作用机制影响的综合反映,且对结构升级、节能减排、成果分享的作用效果尤为明显。进一步研究发现,Ⅱ型大城市和中等城市的国家审计有助于促使本地区经济发展质量提升,但对周边城市却有明显的抑制作用;而Ⅰ型及以上大城市和小城市的国家审计对本地和周边城市经济发展质量均未产生明显影响。结果表明,强化国家审计功能、推进跨区域协同审计,对于推进经济高质量发展具有重要意义。
