基于期刊论文的中国地级以上城市知识专业化研究

将287个地级以上城市（不包括港澳台地区）作为研究对象,以中国知网发布的168个学科领域期刊论文数量为数据来源,对中国地级以上城市知识专业化水平、影响因素及其与经济发展的关系进行了研究。研究发现：① 中国地级以上城市的专业化水平总体偏低,多样化水平较为明显;知识专业化水平西部地区>中部地区>东部地区;地区相对专业化指数随城市行政等级依次升高,即直辖市<副省级城市<省会城市<普通地级市。具有资源优势的城市,其知识专业化领域高度集中在以资源为基础的领域;中小城市的知识专业化领域相对较少,专业化程度高;大中城市知识专业化领域多,多样化趋势明显,但各领域的知识专业化程度相对较低。从城市等级上来看,知识专业化程度表现为五线城市>四线城市>三线城市>二线城市>一线城市。② 知识专业化水平主要受科教经济因素、人才潜力和服务业因素、工业基础因素、人口规模因素四大因素影响。③ 知识专业化与经济发展关系密切,整体呈现倒U形关系;但各区域随发展阶段不同,表现出不同的形式可以分为U形、倒U形、M形和W形4种大类型。     

基于共生理论的中国沿海省市海洋经济生态协调模式研究

建立海洋生态与海洋经济的共生演化Logistic模型,通过压力-状态-影响-响应（PSIR）模型对Logistic模型中的基本指数进行求解,进一步计算海洋生态与海洋经济之间的共生系数,结果表明：天津和上海两市发展模式已摆脱资源索取模式,其海洋经济生态共生模式的探讨意义较小;其余沿海九省中,河北、江苏、广西和海南4省处于反向共生水平,辽宁和山东两省呈现并生模式,浙江和广东呈现出生态受益的偏利共生模式,福建则呈现出经济受害的偏利共生模式。根据沿海各省市海洋经济生态共生模式,提出相关的政策建议,以期对沿海省市今后的经济和生态发展模式提供理论依据。     

资本积累驱动下不同尺度地理空间的不平衡发展——史密斯马克思主义空间理论探讨

尼尔·史密斯是世界知名的人文地理学者和马克思主义地理学家。他在不平衡发展理论的基础上,整合马克思主义和地理学的资本周期运动、空间一体化与尺度推移等范畴,提出了实现平衡发展的途径,极大地丰富和发展了马克思主义地理学,为研究当代社会空间问题提供了更为具体的分析框架和新的理论解释。其理论的核心是把地理空间视为生产资料、社会产物以及空间关系的总和,认为地理空间生产是特定时期资本增殖的重要方式。目前中国学者虽引进其部分理论,但整体了解还比较欠缺。本文将其理论概括和梳理为空间生产、地理尺度、美式帝国主义、绅士化4个方面,分析资本积累驱动下地理空间的不平衡发展过程,深度解析社会、空间与地理的尺度交错与互动关系,阐明资本周期运动、美式帝国扩张和绅士化的逻辑关联,最后以租隙理论为主剖析了城市尺度的资本周期运动。本文旨在为国内学者研究史密斯的马克思主义空间理论以及马克思主义地理学提供纲要和逻辑线索,并为中国城市化转型和经济增长方式转变提供理论参考和方法启示。     

Urbanizing the nation-state? Notes on the geopolitical growth of cities and city-regions

This article suggests that the developments during the past few decades indicate a qualitative shift in the city/state relation, and conceptualizes this shift as the geopolitical growth of cities and city-regions. Originally a state-orchestrated process, today this is manifested in the attempts of major cities and city-regions, in particular, to demand a stronger national and international political role even as claims are made for urban separatism. This process is connected to a geopolitical reasoning of the heightened role of cities in inter-state competition during the age of post-Fordist capitalism. Furthermore, the geopolitical growth of cities and city-regions is partly constituted in academic theories and expert knowledges that combine certain type of urbanism, economic growth, and political success, and which in so doing destabilize state-centered geopolitical imaginations.     

资源枯竭型城市空间扩展进程研究——以淮北市为例

城市空间扩展是衡量新型城镇化背景下城市化进程的重要指标之一,对于研究资源枯竭型城市的可持续发展也有重要的意义。以遥感影像为基础,结合ArcGIS和Matlab软件实现建成区范围的自动提取;选取城市化强度、重心和紧凑度等指标,分析资源枯竭型城市空间扩展的时空特征;结合研究区实际情况和部分统计数据探讨了城市空间扩展驱动机制。结果表明：1992-2016年,淮北市建成区面积由13.64 km²增加到130.19 km²,净增8.54倍。城市化强度水平处于中等程度,城市扩展强度处于较高的水平,城市土地利用集约程度不高;重心总体呈现出东偏的姿态,建成区用地紧凑度逐渐下降。经济及人口、政府决策、交通水平和采煤塌陷区分别是研究区城市空间扩展的驱动机制、引导机制、内生机制和限制机制。     

京津冀城市群创业风险投资的时空分布特征及影响机制

创业风险投资是京津冀城市群一体化协同创新进程中的重要驱动力。本文利用社会网络分析方法分析了京津冀城市群创业风险投资的时空分布特征,在此基础上利用引力模型和计量分析模型揭示京津冀城市群创业风险投资时空分布的影响机制。主要结论为：京津冀城市群的创业风险投资网络在总额方面具有一定的周期波动性,其时空分布的不均衡性缓慢降低,创业风险投资的三中心(北京、天津和唐山)对周边城市具有一定的带动作用;创业风险投资在城市间的流动呈现出一定的网络性,但是发育缓慢,具有很强的向心性;创业风险投资对创业项目不同阶段的投资从偏重创业后期逐步趋向各阶段均衡发展;信息基础设施发展水平和经济发展水平与创业风险投资之间具有较强的正相关作用;金融环境、服务业发展水平相对滞后,对创新创业成果的转化和资金吸引能力较弱。     

资源产业依赖、人力资本与“资源诅咒”假说——基于资源型城市的再检验

利用2003—2013年中国典型资源型城市的面板数据,在考虑潜在内生性的条件下,使用动态面板系统广义矩估计方法,开展"资源诅咒"假说的再检验,进一步讨论资源型城市的人力资本能否有效缓解"资源诅咒"。结果表明:中国资源型城市普遍存在"资源诅咒"现象;人力资本对经济增长的正向作用虽在一定程度上可以弥补资源产业依赖对增长的负向作用,但却不能明显抑制"资源诅咒";资源型城市普遍存在资源产业依赖对人力资本投资的"挤出"。     

Urban policy mobilities,argumentation and the case of the model city

In recent years urban geographers have devoted considerable attention to the dynamics of policy mobility. After reviewing the progress achieved in this literature, in this article I offer two distinctive contributions. First, I draw on the “argumentative turn” in policy studies and related fields in order to develop an alternative conceptualization of urban policy mobility that pays greater attention to its discursive and argumentative aspects. I thus reassert the significance of democratic processes in the negotiation of urban policy. Second, I outline an alternative methodology for the study of urban policy mobility, focusing on the analysis of argumentation. I apply this methodology to historical instances of urban policy mobilities arising from a recent research project that aimed to historicize the phenomenon of the “model city,” defined as the local deployment of another city’s experience as an argumentative resource supporting particular policy claims.     

Spatial patterns of retail activity and street network structure in new and traditional Israeli cities

The association between spatial patterns of retail activity and the spatial configuration of street networks was examined by means of the space syntax methodology in eight Israeli cities that represent two city types, characterized by different planning approaches and urban growth: (i) new towns, which were established according to a comprehensive city plan and modern planning concepts of “tree-like” hierarchical street networks and “neighborhood units”; (ii) older cities, where street networks and the spatial patterns of retail activity were formed incrementally during their growth. Unlike in older cities, retail activity in new towns concentrates in relatively less-accessible and intermediate locations. This is indicated by a weak correlation between retail activity and the street network’s Integration and Choice centrality measures. The comparison between Israeli cities illustrates the influence of urban growth and planning approaches on the formation of retail activity and its interaction with the structure of the street network.     

Anticipatory logics of the smart city’s global imaginary

The smart city encompasses a broad range of technological innovations which might be applied to any city for a wide variety of reasons. In this article, I make a distinction between local efforts to reshape the urban landscape, and a global smart city imaginary which those efforts draw upon and help sustain. While attention has been given to the malleability of the smart city concept at this global scale, there remains little effort to interrogate the way that the future is used to sanction specific solutions. Through a critical engagement with smart city marketing materials, industry documents, and consultancy reports, I explore how the future is recruited, rearranged, and represented as a rationalization for technological intervention in the present. This is performed amidst three recurring crises: massive demographic shifts and subsequent resource pressures, global climate change, and the conflicting demands of fiscal austerity that motivate the desire of so many cities to attract foreign direct investment and highly skilled workers. In revealing how crises are pre-empted, precautioned, and prepared for, I argue that the smart city imaginary normalizes a style and scale of response deemed appropriate under liberal capitalism.
