Everyday effects, practices and causal mechanisms of ‘cultural embeddedness’: Learning from Utah’s high tech regional economy     

Al James 《Geoforum》2007,38(2):393-413

In recent years, economic geographers have drawn extensively upon notions of ‘cultural embeddedness’ to explore how spatially variable sets of cultural conventions, norms, values and beliefs shape firms’ innovative performance in dynamic regional economies. However, our understanding of these causal links remains partial, reinforced by an ‘over-territorialised’ conception of cultural embeddedness which sidelines the role of institutional actors operating outside and across the boundaries of ‘the local’. So motivated, this paper offers a theoretically-informed - and theoretically informing - empirical analysis of the high tech regional economy in Salt Lake City, Utah to explore the everyday causal mechanisms, practices and processes - both local and extra-local - through which firms’ cultural embedding within the region is manifested, performed and (un)intentionally (re)produced. In so doing, this paper aims to further our understanding of the constitutive entanglement and complex interweaving of cultural/economic practices, and to contribute to the development of an in-depth empirical corpus of work which compliments the exciting conceptual developments that have largely dominated cultural economic geography over the last decade.  相似文献

重庆市都市区人口、资源、环境与经济系统协调发展探析   总被引：4，自引：1，他引：4  

李孝坤 《云南地理环境研究》2005,17(2):37-41

人口、资源、环境与经济系统的协调是城市经济系统可持续发展的核心．但系统协调度的量化具有高度的复杂性、开放性和不确定性。以重庆市都市区为例，采用协调度模型(公式)计算出1996～2001年各年的协调度值，并结合重庆市实际对协调度进行了等级划分和判识，结果表明：从1996～2001年系统协调度呈现由极不协调到不协调到弱协调的变化趋势，同时也表明系统协调度总体水平尚低。最后提出了促进重庆市都市区系统协调发展的若干对策建议。  相似文献   

城市空间结构演变的空间过程和动力因子分析   总被引：6，自引：0，他引：6  

王开泳  王淑婧  薛佩华 《云南地理环境研究》2004,16(4):65-69

城市空间结构是城市地理学、城市规划学的核心研究内容之一。城市空间结构的演变作为一个十分复杂的社会现象，一直受到各方面学者的关注。通过着重分析城市空间结构演变的主要空间过程：空间竞争、空间演替、空间扩散、空间均衡等，并对这些空间经济过程做出横向分析，讨论城市空间结构与城市经济运行之间的内在联系。分析城市空间结构演变的主要动力因子：包括完善的服务和基础设施、土地集约利用、城市产业的人口需求等集聚因子和环境承载力、级差地租、现代技术的发展等离散因子，从而论证集聚力和离心力的交互作用对城市空间结构演变产生深刻影响。  相似文献   

The non-agricultural economy in post-socialist rural Romania: The insights and perceptions of national, regional and local institutions     

Wilfried Heller 《GeoJournal》1998,46(3):199-205

This study evaluates some aspects of the socio-economic transformation of rural Romania with reference to the views of representative organisations (at national, regional and local levels) and other experts. Interviews conducted in ten communes of nine Romanian counties (‘judete’) focus attention on the advantages and disadvantages of system change experienced since 1989; the most important problems and constraints for future socio-economic change; and appropriate policies and perspectives for development in the immediate future. Wherever appropriate the claims of interviewees are substantiated through reference to statistics, drawn in many cases from Chambers of Commerce & Industry (CCI). Local level representatives presented much more negative views on recent change than their national and regional level counterparts, but all agreed on the crucial problem of capital shortage. Thus while specific programmes to assist rural areas are justified, they cannot fully succeed until the national economy is able to grow more rapidly and attract greater foreign investment. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

The role of moral economy in two British Columbia fisheries: Confronting neoliberal policies     

《Marine Policy》2015

What have been the moral values and practices allowing equitable economic opportunities and a sense of fairness in North American small-scale fisheries? How have these “moral economies” been affected by neoliberal policies with their emphasis on efficiency, rational self-interest, and wealth accumulation? Focusing especially on the salmon and halibut fisheries in British Columbia, Canada, this discussion summarizes key findings on the manner in which small-scale fisheries and their moral practices tend to be marginalized and undervalued under neoliberal regimes. The paper considers the value of these moral economies for promoting social, economic, and ecological welfare as grounds for the expansion of small-scale fisheries.  相似文献   

黄河流域夜间灯光数据与社会经济发展指标的时空耦合关系研究     

张远生  曹智伟  韦蔚  胡洁 《测绘通报》2021,(10):20-27

本文通过对1992—2013年全国夜间灯光数据的校正和处理,获得全国及流域夜间灯光数据影像,进行经济空间聚合分析,以及与相关因子进行对比分析。研究结果表明：经济空间聚合高的区域分布在黄河河道附近,从黄河上游到下游,热力强度逐渐增强,并且以省会城市为核心区向外扩散,即呈现为在旧聚合点聚合度加剧的情况下,聚合区域有向周边分散的趋势;夜间灯光数据的变化趋势与GDP的变化趋势具有一定的相似性,并且与城镇化率、人口数量、第三产比例、人均公园绿地面积、流域发展指数（BDI）具有一定的相关性;流域9省（自治区）的夜间灯光数据整体变化趋势与全国灯光数据的变化趋势基本一致,呈稳定上升的趋势,但整体值均低于全国的夜间灯光数据,并且差距有所扩大,黄河流域高质量发展迫在眉睫。  相似文献
