Cleantech clusters: Transformational assemblages for a just,green economy or just business as usual?

The rhetorical zeal for green enterprise as a global fix for the tripartite challenges of economic recession, environmental degradation and social inequality is increasingly visible in state and non-state pronouncements around the globe under the banner of ‘The Green Economy’. In particular, many policy-facing statements call for transitions leading to a transformation in development practices. Yet there is little detail either in policy or research regarding the types of transitions needed and how they are to be initiated, nor agreement about what a transformed economy might look like. Despite this, there are emergent activities within the cleantech arena which are being heralded as actually existing examples of green economy activities. One means through which these activities are seeking to exert influence over development trajectories is by clustering both at the subnational and transnational level. While diverse in formation, many of these clusters are hybridised, involving actors from public, private and civil society sectors. Critiquing the efficacy of mainstream industrial cluster theory to analyse hybridised cleantech clustering, this paper presents a unique synthesis of current thought on multiscalar environmental governance and socio-spatial formations to explore the practices and potentialities of these hybridised cleantech clusters. Surveying the landscape of cleantech clustering and meta-clustering, before focusing in depth on one case study, the contribution of clustering to transitioning towards a transformed green economy is considered. Despite strong forces, both within and beyond cleantech clusters, for maintaining neoliberalised approaches to cleantech activity, it is concluded that for as long as cleantech clusters remain open and inclusive of actors proposing alternative pathways they do represent potential, albeit provisional, assemblages for transformation.     

论工业变化的综合研究：以澳大利亚制造业为例

80年代以来,国际工业地理学界采取不同的方法途径对工业变化进行研究。本文在分析这些方法的基础上,提出将工业组织变化与工业区域变化、工业结构变化加以结合,以弥补在工业区域和结构变化研究中忽视组织决策因素,在工业组织变化研究中忽视把区域作为一个整体。基于大量统计数据和本人实地调查资料,本文应用这种综合方法研究了70年代以来澳大利亚的工业变化。     

中原城市群与产业群耦合发展研究

依托空间偏离-份额模型建立了产业群与城市群耦合发展的基本分析框架,并对中原城市群进行了定量诊断。研究结果表明:2001—2013年间,首位城市郑州的产业实力和集聚扩散能力显著提升,产业群与城市群的耦合在地理空间呈圈层式扩展态势,然而城市群尚未形成功能等级与分工协作明确的区域综合经济体。继续实施中心城市带动战略、发挥成员城市比较优势促进城际产业链接、完善城市群综合交通运输网络是促进产业群与城市群耦合、提高群域经济发展水平和增强城市竞争力的有效手段。     

基于新经济地理学的长三角城市群空间格局及发展因素

城市群空间格局发展并非均匀的发展,而是密度(Density)更为集中、距离(Distance)逐渐缩短、整合(Division)更为强烈的过程。基于2009年世界银行发展报告,在劳动生产率基础上分析了长三角城市群空间发展状态。结果表明:1城市化的推进取决于密度的增加,区域发展取决于距离约束的克服,而区域一体化则取决于减少分割并增强整合,因此3D对于认识城市群区域发展及其一体化进程是非常合适的框架。2上海、苏州和无锡表现为3D类型,常州和南京表现为"密度—距离"2D类型,杭州表现为"距离—整合"2D类型,南通等表现为"距离"1D类型,绍兴等表现为"整合"1D类型,扬州等表现出0D类型;3长三角城市群的经济密度、心理距离、制造业专业化指数和外商直接投资均与劳动生产率存在显著性,弹性系数分别为1.727、0.218、0.102和0.237,而交通综合可达性作用不再显著,说明现阶段提升城市群内部经济密度和整合内外部资源比缩短各城市间距离更为重要。     

新时期珠江三角洲城市群发展战略的思考

近年来,国内外经济形势发生显著变化,以传统制造业为主的珠三角城市群面临新的挑战,珠三角下一步如何发展成为必须解决的新问题。现状,将其与国内外城市群对比,提出了珠三角发展战略思路。研究结果表明:2000-2013年期间,珠三角城市群经济发展速度有所降低,区域经济发展差距逐渐缩小;人口红利面临枯竭;产业结构向高级化转变,经济全球化程度下降等;珠三角城市群发展水平和竞争力与国外世界级城市群相比差距较大;与国内长三角、京津冀城市群相比,总体发展势头下降。在此背景下,应将产业技术创新、土地节约集约利用、人口政策创新、区域合作与人文引领作为新时期珠三角城市群发展战略的主要方向。     

Interannual climate variation,land type and village livelihood effects on fires in Kalimantan,Indonesia

The increasing extent and frequency of fires globally requires nuanced understanding of the drivers of large-scale events for improved prevention and mitigation. Yet, the drivers of fires are often poorly understood by various stakeholders in spatially expansive and temporally dynamic landscapes. Further, perceptions about the main cause of fires vary amongst stakeholders, which amplify ongoing challenges from policies being implemented inconsistently across different governance levels. Here, we develop a spatially and temporally-explicit typology of fire prevalence across Kalimantan, Indonesia, a region with significant contribution to global greenhouse gas emissions. Based on livelihood information and data on climate, soil type and forest degradation status, we find that in intact forest the density of fires in villages that largely coincide with oil palm concessions was twice as high as in villages outside the concessions across all years. Fires occurring in degraded land on mineral soil across all years were also most prevalent in villages with industrial plantations (oil palm or timber). On the other hand, in degraded peatland, where fires are most intense during dry years induced by the El Niño episodes, occurrence rates were high regardless of village primary livelihoods. Based on these findings we recommend two key priorities for fire mitigation going forward for policy across different governance levels in Kalimantan: degraded peatland as the priority area and industrial plantations as the priority sector. Our study suggests a fire prevention and mitigation approach, which accounts for climate, land type and village livelihood, has the potential to deliver more effective means of management.     

我国资源型城市产业转型面临的障碍及对策建议

我国资源型城市多兴起于计划经济时代,原有经济结构僵化、地理位置偏远、环境污染严重、人才资源匮乏等制约了其产业转型。要实现产业转型,政府必须及早进行规划,找准城市转型定位,发展替代产业;同时要加大体制改革,大力发展中小企业;努力改善投资环境,吸引外来投资;此外还要加大科技开发力度,以人才优势推进资源型城市转型。     

城中村制造业空间集聚研究——以广州康乐村服装生产企业为例

城中村作为城市内部的异质空间已受到学术界高度关注,但对其内部流动人口创建的各种经济部门,尤其是制造业的系统研究仍然少见报导。选取广州市康乐村为案例地区,通过半结构式问卷调查与访谈、土地利用类型与多层建筑物垂直空间利用状况的系统调研,深入探讨城中村内流动人口创建的制造企业集聚的基本特征及形成机制。研究表明:制造企业在康乐村的集聚是关系邻近与地理邻近循环因果关系引导下的主动集聚。企业具有"临时性"、"内生性"、"地域的多元性"及"非正规性";产业构成以成衣制作为主体,企业规模偏小,生产联系松散,技术需求极其低下;在空间分布上则表现为同行业企业相对集中分布,产业空间与居住空间相互依附,垂直空间混合利用以及企业分布受村内道路系统影响显著等。     

天山北坡城市群空间组织形态的识别研究

 正确认识天山北坡城市群的空间组织结构以及空间发展形态,对于完善绿洲城市群的发展理论和规划具有重要意义。以天山北坡城市群为研究对象,通过资源环境承载力的分析,总结出未来城市群发展面临的客观制约因素;通过中心性分析、断裂点理论修正的Voronoi多边形等方法识别出城市群的中心城市及各自的辐射范围城市;通过引力模型识别出城市之间的社会经济联系强度。据此,利用多维尺度分析的方法,可视化地展现了天山北坡城市群发展的空间组织形态。经调查了解：（1）乌鲁木齐市与克拉玛依市是未来城市群发展的两个中心城市,五家渠市、阜康市、昌吉市、石河子市周边目前属于乌鲁木齐市的辐射范围城市,奎屯市,乌苏市属于克拉玛依市的辐射范围城市;（2）城市群内部的城市之间的联系比较松散,特别是两个中心城市之间联系较弱;（3）城市群的空间发展形态为串珠式,是一种特殊的走廊式空间形态。     

Restructuring the export-oriented industrialization in the Pearl River Delta, China: Institutional evolution and emerging tension

The rise of the Pearl River Delta (PRD) as a promising workshop of the “world factory” in China has attributed to the export-oriented industrialization driven by foreign direct investment, particularly Overseas Chinese investment from Hong Kong and Taiwan initiated in the late 1970s. The export-oriented industrialization has embedded in the flexible institutions favourable for foreign investors and local authorities, via the salient entry mode, i.e. processing with supplied materials (lailiaojiagong). Since the mid-2000s, the export-oriented industrialization has undergone dramatic restructuring to cope with the changing business environment at global, national and regional and firm levels. Drawing upon the evolutionary and institutional perspectives in geographical political economy approach, this study argues that the prevailed institutions conducive for the export-oriented processing have evolved into institutional inertia and territorial embeddedness as obstacles for the on-going restructuring, particularly the market reorientation from export to domestic sale. Moreover, difficulties of restructuring through the state-designated relocation have been heightened by the resistance from below and emerging state-firm tension. The institutional evolution of the export-oriented industrialization in the PRD has enriched the literature on industrial restructuring in the context of dynamic global-local interactions, but also provided fundamental implications for formulating well-coordinated restructuring strategies among various institutions and concerned actors.
