Spatial pricing models have been used to illustrate a tariff's asymmetric effects on consumers located at different points in the protected economy, and to demonstrate that the optimum tariff for a small open spatial economy may be positive. In these models, the distribution of households has been taken as uniform and fixed. We extend the spatial model by allowing households to optimally locate and consume variable amounts of land, as well as the domestic- or foreign-produced good. Land consumption, location rents, and the distribution of consumers are endogenous, responding to tariff-induced changes in the delivered prices of the domestic and foreign goods. Within this limited general equilibrium framework, a neoclassical result resurfaces: from the perspective of private consumers, the optimum tariff in a small open economy is zero. The possibility of a positive optimum tariff, however, may remain intact in a more integrated model where domestic profits and tariff revenues are redistributed within the spatial economy.  相似文献

This paper argues for a renewed consideration of counterfactuals within geography. Drawing upon Doreen Massey's emphasis on notions of ‘possibility’, ‘chance’, ‘undecidability’ and ‘happenstance’, we argue for an engagement with approaches in the humanities that have addressed such issues directly. We review previous uses of counterfactual method in historical geography, particularly as related to cliometrics and the ‘new economic history’ of the 1960s, but argue that a recent upsurge of interest in other disciplines indicates alternative ways that ‘what-if’ experiments might work in the sub-discipline. Recent counterfactual work outside of geography has had a notably spatial cast, often thinking through the nature of alternative worlds, or using counterfactual strategies that are explicitly concerned with space as well as temporal causality. We set out possible agendas for counterfactual work in historical geography. These include: consideration of the historical geographies within existing counterfactual writings and analyses; suggestions for distinctive ways that historical geographers might think and write counterfactually, including experiments in geographies of happenstance, and the exploration of more-than-human possibilities; analyses of the geography of and in counterfactual writing; and study of the political, ethical and emotional demands that counterfactuals make. This discussion and framework provides an extended introduction to this special feature on counterfactual geographies.  相似文献

Wholesale firms play an important role in the distribution of goods. They stimulate the flow of goods towards the final consumer by means of their intermediate position between the manufacturing sector and the retail sector in the distribution channel. This paper will focus on the question whether there is a link between the position of wholesale businesses in the distribution channel and their spatial choice of location. Can the position of the wholesale sector in the distribution channel be regarded as an influential location factor or not? As such, the location factor to elaborate is the location with regard to the suppliers and buyers of wholesale firms. First, the change of the spatial pattern over the long term is set out by means of a series of maps. Second, an inquiry has been set out in order to obtain an insight to the position of wholesale firms in the distribution channel. The major findings are that the sectors of repair shops, retail, manufacturing industry and building industry have the most business contacts with wholesale firms. Most business contacts are on a national level. The position of the wholesale sector in the distribution channel alone does not explain the choice of location. But the paper shows that the position is closely linked to other factors, such as accessibility, short distances and centrality.  相似文献

以中国274个地市为样本,引入空间分析和计量模型等方法,分析外资分布特点及影响因素,结果表明:①中国目前尚不存在大规模外资"逃离"现象,外资利用总量在波动中上升,结构趋于优化。②空间上由集聚集中趋向分散均衡,呈"北进西移"态势,东部高度集中,中西部发展较快。外资高值集聚区逐渐向北推进,低值区向西南收缩;③劳动力成本、市场规模、专业化经济、FDI累积、市场化水平和开放度均对外资有正向作用。其中,传统因素对外资的吸引作用正逐渐下降,FDI累积的作用上升明显,集聚对外资分布作用显著。从不同区域看,集聚经济和FDI累积效应等新经济地理因素在东部外资区位选择中受到更多的关注,而劳动力成本、基础设施、开放水平等传统因素在中西部吸引外资中作用更大。④中国应遵循因地制宜、因时制宜的原则制定差异化的外资政策。  相似文献

This article considers Peter Bowler's recent contribution to the genre of counterfactual history as exemplifying a “restrained” counterfactual framework, one that must downplay the role of contingency in the historical process in order to present what Bowler calls a more “natural course” of historical development. This restrained counterfactual methodology is discussed with reference to analogous debates within evolutionary science about the competing roles of contingency and convergence in the history of life, along with recent work done within the humanities about the more subtle nuances of counterfactual reasoning. Although there is little doubt that Bowler's study will help legitimize the genre of counterfactual history, it is argued that the role of contingency—once thought to be integral to the counterfactual—has been necessarily minimized in order to construct a narrative that is a plausible counterfactual history of science. It is in this way that Bowler's world without Darwin sheds light on our historiographical preconceptions about what makes for a plausible historical narrative.  相似文献

A datum is considered spatial if it contains location information. Typically, there is also attribute information, whose distribution depends on its location. Thus, error in location information can lead to error in attribute information, which is reflected ultimately in the inference drawn from the data. We propose a statistical model for incorporating location error into spatial data analysis. We investigate the effect of location error on the spatial lag, the covariance function, and optimal spatial linear prediction (that is, kriging). We show that the form of kriging after adjusting for location error is the same as that of kriging without adjusting for location error. However, location error changes entries in the matrix of explanatory variables, the matrix of co‐variances between the sample sites, and the vector of covariances between the sample sites and the prediction location. We investigate, through simulation, the effect that varying trend, measurement error, location error, range of spatial dependence, sample size, and prediction location have on kriging after and without adjusting for location error. When the location error is large, kriging after adjusting for location error performs markedly better than kriging without adjusting for location error, in terms of both the prediction bias and the mean squared prediction error.  相似文献

广州城市公共服务设施供给空间分异研究   总被引:5,自引:0,他引:5  
转型期以来,政府治理制度的变革及公私部门关系的重构使我国城市公共服务设施供给主体、供给机制逐步多元化,其分布形态也由空间均衡趋向分异。本文以广州为案例,研究结果表明:广州城市公共服务设施分布总体上呈核心-边缘空间格局,区域供给规模差异大且与人口分布不相协调,区际及不同类型设施的空间聚集水平差异显著;传统计划经济条件下城市公共服务设施空间均衡分布模式被市场经济条件下高收入地区指向的集中布局模式所取代,表现出类似西方国家城市公共资源配置的"反比例服务法则"。  相似文献

This article continues research into social mobility in England in the nineteenth century by examining the links with different occupational structures, socio-economic and industry/occupation, for a specific location. This allows an examination of the impact of the characteristics of these structures on occupational and thence on social mobility. Occupational mobility has long been recognised as a major determinant of social mobility and has been the subject of a number of papers, usually to determine how much a specific variable affects the level and type of mobility observed. Rarely do these analyses consider the location’s occupational structure, and its changes, as a determinant of the level of mobility. This paper finds that much of the variability of occupational mobility of a locality is determined by the characteristics of the different industries and occupations in that location. Industries and occupations provide a context within which other factors, such as literacy, operate.  相似文献

ABSTRACT. Real variable analysis has een used to great benefit in a variety of classical problems in location theory. In this paper we explore basic complex variable techniques in one formulation of the obnoxious location problem. A general definition of center points is first given and used to formulate several alternate versions of the obnoxious location problem. A logarithmic transformation is then used to demonstrate some equivalences between these families of distinct location problems (defined via center points). A prototype logarithmic potential function which results from this formulation is then investigated, and it is demonstrated that the extremal solutions with this objective reside on the boundary of its domain of definition. An application using zero- and one-dimensional centers is discussed, and a generalization to the spatial obnoxious problem is also briefly examined. We define a zero-dimensional center as a critical point of the logarithmic potential function, and it is shown that these centers are equivalent to the solutions of the Complex Moment Problem.  相似文献

Although pharmacies play an important role in providing information and advice on health issues to lower income people in developing countries, the distribution of urban pharmacies is not balanced with respect to population distribution in some of the districts of Istanbul. This situation can severely limit the accessibility of pharmacy services to the people with lower socio‐economic background. A multiple regression analysis is used in order to find out the factors which affect the spatial distribution of pharmacies in Istanbul. The number of pharmacies in the districts considered is taken as the dependent variable and the number of hospital beds, physicians, population, employment, income, number of educated people and distance to the CBD are taken as independent variables. According to the results, the population of the districts and the number of educated people, physicians and hospital beds are the most important factors affecting the location of pharmacies in Istanbul. The other variables are not found significant in affecting the location of pharmacies at the metropolitan level. Suggestions are made for better distribution of pharmacies and for further research.  相似文献

Geographical Information Systems (GIS) are being incorporated into archaeology as a technique to improve the understanding of spatial organization and the relationships among finds within specific areas. Although their use as a basic tool in predicting the location of archaeological sites or in assessing the extent of their catchment areas is relatively common, in general, they have less often been applied to the study of the spatial distribution of archaeological remains within individual deposits, and in particular to faunal assemblages. Despite this, they can prove essential to understanding dispersion and grouping patterns within deposits fully, and, together with various correlation analytical techniques, they provide valuable information about the economic organization of settlements and inhabitant lifeways. To demonstrate the potential of this methodology, a zooarchaeological GIS has been prepared for the Middle and Late Magdalenian and Azilian layers in El Mirón Cave (eastern Cantabria, Spain), and the spatial distribution patterns of various attributes of the archaeological record have been analysed. Significant conclusions in terms of type and duration of human occupation have been drawn.  相似文献

变革中的西方经济地理学:制度、文化、关系与尺度转向   总被引:38,自引:11,他引:27  
苗长虹 《人文地理》2004,19(4):68-76
1980年代以来,在社会科学日益走向多元化和"后现代主义"的背景下,西方经济地理学开始了一个前所未有的急剧变动时期,无论是研究的主要论题,还是研究的内容、理论和方法以及表述的方式与风格,均经历并正在经历深刻的变革。与上一世纪50-60年代的"计量和理论革命"和70- 80年代的"马克思主义转向"相比,这次变革不仅发生在方法论和认识论层面,而且许多也发生在本体论层面,它使西方经济地理学的视角走向了高度的多样化和复杂化。本文在分析这次变革的起点:马克思主义转向及其批判的基础上,从制度转向、文化转向、关系转向、尺度转向4个相互交织的方面,系统勾勒了西方经济地理学理论视角变动的主线,讨论了这些视角变动的方向、成因、意义和局限性。  相似文献

互联网技术应用对零售业空间组织影响研究进展   总被引:1,自引:0,他引:1  
互联网技术应用对零售业空间组织的影响已成为当今学术界研究热点。本文利用文献资料法和对比分析法,梳理了国内外互联网技术应用对零售业空间组织结构、零售企业区位选择与布局、市场空间等方面的影响研究,并提出了未来人文地理学须进一步强化的研究内容。结果表明:20世纪90年代中期以来,互联网技术应用对零售业空间组织影响的研究成果日益丰富,且涉及到经济地理学和商业学等学科,研究方法主要以定性为主,且定量研究日益增多,但对互联网技术应用对传统零售业区位选择和销售腹地的影响、中小网络零售企业空间组织、运输距离对网络零售企业销售空间影响以及出口跨境网络零售企业销售空间格局等方面研究还需完善,未来研究应注重吸收其他学科理论和方法,强化实证研究结论的科学性。  相似文献
