This paper discusses the dynamic cultural economy of British drum and bass (D&B) music, which emerged out of Britain’s rave culture in the early 1990s. We suggest that D&B offers insight into more general issues regarding the relation between alternative cultural economies and capitalism. We examine relations between D&B and the mainstream capitalist economy and argue that D&B calls attention to the possibility for alternatives to conventional capitalist relations to survive and possibly thrive without pursuing separation from capitalism. We also theorize D&B as a vehicle towards empowerment regarding the industry segment vis-à-vis the mainstream music industry and also regarding D&B’s practitioners, many of whom can be understood as marginalized discursively and/or materially. However, D&B empowerment is fragile, due in part to technological changes that threaten practices that have helped cultivate innovativeness as well as communal relations. The empowerment of alternative practices is fragile not only for D&B as an industry segment, but also from the vantage point of internal power relations – notably with respect to differences along axes of gender and generation/age. Our conclusions indicate the broader significance of the paper for critical social theory and propose how new research might build on our dynamic view of D&B’s cultural economy.  相似文献

基于第五(2000年)、六次(2010年)全国人口普查数据和社会经济统计数据,利用综合空间评价方法和耦合协调度模型,探讨中国341个地级及以上行政单元的人才优势度与经济发展的空间差异特征,并系统分析两者间的耦合协调关系。结果表明:1)中国经济发展的地区差异明显,2000―2010年大部分地区的经济发展水平处于上升的趋势并呈现出“大范围扩散、小范围集聚”的趋势。2)中国人才优势度存在明显的空间差异,呈现以北上广深为绝对高地,以其余直辖市、省会城市和计划单列市为相对高地,其余地区为低地的空间结构。2000―2010年人才优势度的空间差异日益突出,表现为东部地区与中西部地区之间的差距以及同一省份内省会城市与非省会城市之间的差距进一步拉大。3)基于耦合协调度系统评价,把所有地区划分为以下3种类型:高耦合度-高协调度地区、高耦合度-低协调度地区、低耦合度-中协调度地区。2000―2010年东部地区“高耦合度-高协调度”趋势加剧,中西部地区“高耦合度-低协调度”趋势加剧。  相似文献

ABSTRACT

Limitations in scale, infrastructure and business opportunities in combination with a greater sense of community in small centres require a more diverse understanding of the small city creative economy. Entrepreneurship and business development builds on non-capitalist resources, creative community initiatives, volunteers and community networks. Fostering the creative economy in small cities requires a rethinking of creative narratives that iterate the key role of non-capitalist community resources. I illustrate this argument via a case study of the Blue Mountains Music Festival, in New South Wales, Australia. It examines the gap between creative economy aspirations of a small city government and the reality of creativity ‘on the ground’. The City of the Blue Mountains is a small urban centre on the fringes of metropolitan Sydney and regional New South Wales. Its council has recently adopted a creative industries approach to enhance local employment in line with national and metropolitan creative agendas. The Blue Mountains Music Festival was launched in response to creative economy policy more than 20 years ago, but has now lost this connection as it fails to fit current policy aspirations. The festival is, however, an effective example of how creativity in a small city unfolds, demonstrating that beyond jobs and growth are key matters of non-capitalist community networks and resources.  相似文献

This paper presents an inquiry into the capacity of transport and mobility studies to critically engage with contemporary policies. Drawing on the conceptualization of circuits of knowledge, the paper scrutinizes the extent to which transport policy agendas are framed around various approaches within academia. An extensive literature review reveals that the academic field of transport and mobility is organized around a hegemonic core of “neoclassical” and “sustainable” approaches. Meanwhile, a critique of these dominant approaches is emerging in an attempt to (re)embed mobility issues in urban political economy. This threefold knowledge typology visibly resonates within transport policy agendas in Brussels, where we detect a growth-oriented and largely depoliticized dual hegemony of neoclassical and sustainable narratives, with critical academic voices rarely entering official agendas. The paper concludes with a reflection on the difficulties, yet also the need to mobilize critical academic knowledge in the field of transport and mobility.  相似文献

适宜性人力资本与区域经济协调发展   总被引:3,自引:3,他引:0  
生延超  周玉姣 《地理研究》2018,37(4):797-813
适宜性人力资本必须与区域产业结构、区域经济发展模式相匹配,才能最大程度地发挥不同层次人力资本的效能,以有效提升区域经济发展水平。从全国和区域层面出发,基于ESDA方法和空间计量分析方法,运用1998-2014年全国30个省市的面板数据,从初级、中级、高级人力资本、物质资本、劳动力、全要素生产率等要素视角探寻适宜性人力资本促进区域经济发展效能的空间差异,研究表明:① 人力资本与省域生产总值水平均存在显著的空间相关性和路径依赖性。② 在全国层面,初级、中级人力资本对区域经济增长作用不显著,高级人力资本则作用很明显。③ 在区域层面,东部及东北地区区域经济发展主要依赖高级人力资本,中部和西部初级人力资本贡献显著,中级人力资本在四个区域均不显著。这为区域人力资本培育和区域经济高速发展政策制定奠定了理论基础。  相似文献

从空间自相关视角厘清经济发展水平较高和较低地区的空间组织关系演化规律对区域经济健康发展具有重要意义。在界定集极、孤极和外围等概念基础上,运用地统计分析方法,按两级三区和三级五区结构体系分别构建江苏省全局和局部经济空间极化结构,分析其演化过程,结果显示:①全局空间集极范围不断扩大,孤极数量减少,逐渐形成南集极北孤极、南极北外的空间结构,其间空间自相关作用逐渐增强,区位是极化动因; 局部空间演化走势不尽相同:沿江和沿京杭运河地区经济空间极化结构逐渐升级,而沿东陇海和沿海地区却相对恶化。因此认为当前江苏省全局空间中南北显著分化和局部空间相背演化现象值得关注。  相似文献

中国数字经济空间分异及影响因素   总被引:1,自引:1,他引:0  
基于腾讯研究院公布的数字经济指数,运用插值模拟、Zipf位序-规模法则及地理探测器等方法,对2016年中国数字经济发展的空间分异特征进行分析,并对其影响因素进行探测比较。结果表明:中国数字经济发展空间分异明显,省域尺度呈现出自东向西梯度递减的特征,但川、渝成为创新发展新极点;城市尺度,城市群地区是数字经济发展高地。数字经济各分维度发展的协同性与差异性特征并存,但差异性更为显著。国家层面,政府对科学技术方面的投入对数字经济的发展起重要作用;东部地区影响因素相对多样;信息化基础与潜力方面因素对中部地区起主导作用,且各因素交互后作用力显著加强;西部地区受多种因素的综合作用,不存在具有决定性的影响因素;东北地区的影响因素则相对单一。  相似文献

Material stocks in infrastructure, buildings and machinery shape current and future resource use and emissions. Analyses of specific countries and selected materials suggest that material stocks might saturate, which would be important for a more sustainable social metabolism. However, it is unclear to what extent the evidence holds for a wider range of stocks and flows, as well as for world regions or globally.We present an inflow-driven dynamic stock-flow model for 14 bulk materials, end-of-life outflows, recycling, and waste flows for nine world regions from 1900 to 2015, extended with trend scenarios until 2035. Material stocks are growing in all regions and show little signs of saturation yet. In 2015, China used half of global stock-building materials, overtook everyone in stock size around 2012 and grows its stock at ∼8%/year. The Industrialized regions, including the Former Soviet Union, are slowly expanding their high stock levels at ∼1%/year. Stocks in all other regions, inhabited by 60% of the world population, grow at ∼3–5%/year. Inequalities in per capita stocks between regions are large. Trend scenarios suggest potential absolute or per capita stock saturations in some of the industrialized regions, while all other regions are expected to continue high stock growth.Accumulated stocks drive future end-of-life materials and substantial maintenance and replacement requirements. Growing material stocks hamper a potential stabilization or reduction of resource use. Low stock levels in most world regions suggest a crucial window of opportunity for avoiding resource-intensive stock development. In the industrialized regions and especially China, stabilising and reducing resource use requires halting net stock expansion and transforming existing stocks. More materials- and energy-efficient and long-lived stocks which deliver high quality services, and improved reuse, repair and recycling of increasing end-of-life materials to close loops and actually replace virgin resources, are crucial for a more sustainable social metabolism.  相似文献
