浅谈如何在投标阶段控制岩土工程造价     

刘菊 《城市地质》2015,(Z2)

以岩土施工企业的角度论述岩土项目,在投标阶段对工程造价控制的重要性,以及如何在投标阶段通过优化技术设计、优化施工组织设计进行造价控制,通过招标文件及合同条款进行投标报价,并通过将成本控制提前到投标阶段以有效解决施工阶段容易出现的各种问题,提前控制岩土工程工程造价。  相似文献   

厦门台企空间分布及区位选择分析     

王彬  陈玉闽 《福建地理》2011,(1):1-7

厦门是台商投资大陆最早和影响较大的城市之一.通过对厦门1 016条台企及其类型统计,并计算其地理集中指数;结合调查问卷和GIS技术,进行台企空间特征和台商投资厦门区位分析.研究结果表明:厦门的台企在空间分布上呈现岛内密集并逐渐向岛外迁移的趋势;在产业类型上以制造业为主,但其地理集中指数低于服务业;从台商投资区位选择角度分析,影响厦门台企分布的主要区位因子是市场、政策和环境,但近年来也面临着地区竞争和其他诸多不确定因素的制约,使得台企向厦门周边和其他地区迁移.  相似文献

机场周边地区生产性服务业与制造业空间布局特征——以首都机场为例   总被引：2，自引：0，他引：2  

柳坤  申玉铭  刘辉 《地域研究与开发》2015,(4)

空港经济对推动城市产业空间调整和城市经济转型具有重要意义。以首都机场为例,运用Ripley’s K函数及核密度估计法分析机场周边地区生产性服务业与制造业的空间布局特征。生产性服务业和制造业的区位布局均呈现出明显的向心性,其中,物流业、制造业和金融业的向心性最强。生产性服务业和制造业空间集聚强度呈先增后减的倒"U"型特征,生产性服务业企业集聚强度明显高于制造业企业集聚强度,不同行业企业空间区位选择距离阈值存在差异。不同行业空间分异特征显著,集聚模式不同。制造业呈"大分散、大集聚"模式;商务服务业、科技服务业、信息服务业及物流业呈"小分散、大集聚"模式;金融业呈"大分散、小集聚"模式。城市主要交通干线附近及成熟的产业园区是生产性服务业与制造业主要集聚地,信息服务业、商务服务业以及科技服务业的区位选择具有较强一致性。  相似文献

山东地区三类典型制药企业的VOCs源成分谱及排放特征研究     

苑雯雯  王霞  高素莲  孙晓艳  范国兰  王琛 《南京气象学院学报》2020,12(6):758-766

制药行业因在提取等过程中使用有机溶剂排放大量挥发性有机物（VOCs）而备受关注.本研究在山东省选择化学合成、生物发酵、中药共三家制药企业开展了107种VOCs组分的监测和分析,并建立制药企业的VOCs源成分谱.研究结果表明：化学合成类和生物发酵类制药企业排放总质量浓度均超过20 mg/m³,中药制药企业的样品的平均质量浓度相对较小,为902.66 μg/m³.本研究所分析的107种组分中,以含氧挥发性有机物（OVOCs）为主,三家企业均超过75%,其中,化学合成制药类卤代烃物种的占比较高.企业类型、生产环节、收集排放措施等是影响VOCs成分的重要因素.  相似文献   

Institutions,Location, and Networks of Multinational Enterprises in China: A Case Study of Hangzhou   总被引：1，自引：0，他引：1  

《Urban geography》2013,34(7):639-661

Based on interviews with local government officials and a survey of 44 foreigninvested enterprises (FIEs), this article examines the significance of local formal institutions for intramunicipal location decisions of multinational enterprises (MNEs) and for network properties of their investments in Hangzhou, China. This study finds that local formal institutions, in terms of municipal district governments and development zone authorities, are a significant force influencing the location decisions of MNEs within Hangzhou. These local entities shape the intramunicipal location decisions of MNEs through three primary vehicles including financial incentives, industrial infrastructures, and attitudes toward foreign investors. The start-up fiscal capability of local formal institutions is therefore central to the foreign investment development efforts. Local formal institutions, however, are a less significant force influencing the network properties of FIEs in Hangzhou. District governments and zone authorities are largely confined to measures for co-locating allied foreign supplier investments to promote FIE local linkages.  相似文献   

Getting Globalized: Urban Policy and Industrial Displacement in Williamsburg,Brooklyn     

《Urban geography》2013,34(6):461-482

We hypothesize that as the "global city" label becomes ever more central to a city's identity, local urban government policy increasingly supports those economic sectors that city leaders see as being congruent with the global and increasingly undermines sectors that serve primarily local markets. Through an in-depth study of small-scale manufacturers in the Williamsburg neighborhood of Brooklyn, in New York City, we examine the extent to which and the ways in which local policy undermines otherwise healthy locally oriented businesses. We find that the City's assumption that urban manufacturing is a dying breed becomes a self-fulfilling prophecy, largely via the City's own treatment of its manufacturing businesses. Through a lack of enforcement of zoning codes, zoning variances and rezoning initiatives, and more quotidian policies of harassment over noise and other quality of life complaints, the City is making it more difficult to do business for small-scale manufacturers. These policies then create a conventional wisdom that sees the City as a difficult place to start and grow a business.  相似文献   

Crafting Regional Cultural Production: emergence,crisis and consolidation in the Gold Coast surfboard industry   总被引：1，自引：0，他引：1  

Andrew Warren 《The Australian geographer》2013,44(4):365-381

Surfboard-making is concentrated in regions with vibrant surfing subcultures, suitable waves and sufficient expertise in crafting boards, by hand, to suit prevailing coastal conditions. This article charts the rise of the Gold Coast as Australia's most concentrated cluster of surfboard-making, from its origins as do-it-yourself craft in backyards and sheds, to professional, export-oriented industry. Out of highly informal, subcultural origins, a regional cluster emerged in the 1960s, fuelled by the growth of surfing, tourism and suburban development, and by the needs of surfers for customised boards that suit their body size, surfing style and local wave conditions. What transpired was a vernacular form of coastal creative industry combining craft skills, subcultural knowledge and design flair. Nevertheless, a mix of factors, including automation, increased competition from cheap imports, increasingly aggressive retail trade, and mistrust among board-makers, has threatened viability. Some workshops overextended into export production, marketing and automation, and consequently suffered from exposure to risk (as well as a commensurate decline in regional tourism). Others survived, and in some ways turned full circle: those small workshops continuing to service local markets, within their means, were most able to ride out the industry's turbulent times. Small-scale cultural production persists despite the volatility of the larger brands, geared instead around loyal customers who want hand-crafted boards made by shapers who they know and trust.  相似文献   

Changes in regional employment in Denmark in the seventies     

Bue Nielsen  Peder Michael Sørensen M.Sc. 《Geografisk tidskrift / udgivet af Bestyrelsen for Det Kongelige danske geografiske selskab》2013,113(1):69-73

Nielsen, Bue and Sørensen, Peder Michael: Changes in regional employment in Denmark in the seventies. Geografisk Tidsskrift 84, 69–73. Copenhagen, January 1984.

The paper deals with regional development in employment in Denmark in the 1970's. It uses shift-share analysis to isolate elements and activities responsible for the regional dispersion experienced. In that context the paper discusses the interrelationship between manufacturing industries and public services.  相似文献
