Three Taiwan-based economists employ a range of exploratory spatial data analysis tools (e.g., Moran's I and LISA statistics) to investigate trends in the growth of China's exports over the period 1991-2008. A particular focus is on the detection of spatial correlations between China and 40 export destination countries in major world regions. Emphasis in the paper on the key years of 1991, 2001, 2006, and 2008 has enabled the authors to analyze the impacts on China's trade of such major events as the country's accession to the World Trade Organization and the global economic crisis of 2008-2009. The results of the spatial analysis reveal the continuing importance of the U.S. and Asian countries in China's export trade (despite changes in the character of trade relations) and identify the spatial outliers (e.g., in Latin America) that may serve as the basis for new export markets for China in the future.  相似文献

Technical changes in the field of transport, communication and information technology, together with long-term structural shifts will, in the new century, allow a degree of spatial reorganization of European economic activity. The validity of conventional (spatial) models of peripherality is increasingly questionable. They should be supplemented by more appropriate 'aspatial' concepts. Although many elements of these are already well understood, coherent models and operational indicators are required. These could provide a sound theoretical basis on which to further the European Spatial Development Perspective's polycentric development objective. They could also provide new opportunities for peripheral regions, and relief from 'overheating' at the core.  相似文献

国际社会在对待全球变暖问题上经历了从科学回应到政治回应的发展过程。一方面,全球变暖科学理论的发展为国际气候科学界达成有关共识提供了基础,同时为政治家的政治决策提供了相关的科学背景知识,从而为全球变暖问题在20世纪80年代的政治化创造了必要的前提条件。另一方面,国际社会对全球变暖问题的政治回应过程反映了更为复杂的国家集团间的利益矛盾,主要包括南北矛盾和北方内部的矛盾,它们的妥协和合作是确保温室气体减排成功的关键因素。  相似文献

In the 1970s and 1980s, regional analysis was an influential part of archaeological research, providing a discrete set of geographical tools inspired by a processual epistemological and interpretive perspective. With the advent of new technologies, new methods, and new paradigms, archaeological research on regional space has undergone significant changes. This article reviews the state of regional archaeology, beginning with a consideration of its history and a discussion of the fundamental issues facing regional investigations before focusing on developments over the last several years. On one hand, the diversification of archaeological theory has created new paradigms for thinking about human relationships with one another and with the physical environment across regional space; in this regard, historical ecology, landscape archaeology, and evolutionary theory have been particularly influential in recent years. This has led to a corresponding diversification of the traditional methods of regional analysis. Most notably, the advent of powerful digital technologies has introduced new tools, especially those from the geographic information sciences, that build on the quantitative methods of past approaches. The investigation of regional data is no longer based on a discrete toolkit of simple mathematical and graphical procedures for representing spatial relationships. Instead, regional archaeology has matured into a diversity of multiscalar spatial and geostatistical techniques that inform many areas of archaeological inquiry.  相似文献

GeoDa : An Introduction to Spatial Data Analysis   总被引:49,自引:0,他引:49  
This article presents an overview of GeoDa™, a free software program intended to serve as a user-friendly and graphical introduction to spatial analysis for non-geographic information systems (GIS) specialists. It includes functionality ranging from simple mapping to exploratory data analysis, the visualization of global and local spatial autocorrelation, and spatial regression. A key feature of GeoDa is an interactive environment that combines maps with statistical graphics, using the technology of dynamically linked windows. A brief review of the software design is given, as well as some illustrative examples that highlight distinctive features of the program in applications dealing with public health, economic development, real estate analysis, and criminology.  相似文献

13—14世纪意大利城市锡耶纳经济获得了飞跃发展,新兴平民阶层迅速崛起,同过去占主导地位的权贵家族分庭抗礼,并最终超越后者而建立了九人体制的共和政府。这种政治经济变迁使得锡耶纳的城市布局发生了重大转型。共和政府以前,城市布局主要以散布全城、各自为政的贵族私邸和塔楼构成。当平民对贵族的政治斗争取得决定性胜利后,平民主导的共和政权为了塑造合法性和显示政治权威而着手建设市政厅、市政广场,并延请艺术家创作富含政治寓意的市政厅壁画。锡耶纳城市空间的转型实际上从一个侧面反映了这一时期意大利城市权力的重大转移。  相似文献

Over the past five decades, archaeologists have proposed a wide range of methods for the study of spatial organization within hunter-gatherer sites. Many of these methods sought to identify the spatial location of activities based on patterns of behavior observed in ethnographic contexts. While this resulted in productive observations at certain sites, many of these methods were tailored to specific situations and thus could not be applied to a wide range of sites. For example, open-air sites rarely contain preserved bone or features, such as hearths, which were central components to identifying characteristics of site structure. In addition, many of these methods often did not take into consideration the temporal dynamics of the occupation, i.e., that many sites were formed through subsequent occupations of differing duration. This paper proposes the use of two related methods that assume many assemblages are the result of more than one occupation. The methods target the distribution of lithic artifacts, the most ubiquitously preserved of archaeological materials, and accounts for the potential that the final resting place of artifacts was the result of both intentional and unintentional movement by humans and a host of biological and geological processes. The main goal of this paper is to use an understanding of how these processes influenced the formation of site structure to estimate the relative number and duration of occupations for each site in the sample. These new methods will be presented and explained through the study of seven open-air Middle Paleolithic sites in France but are applicable to a wide range of hunter-gatherer sites.  相似文献

Local forms of spatial analysis focus on exceptions to the general trends represented by more traditional global forms of spatial analysis. There is currently a rapid expansion in the development of such techniques but their history almost exactly parallels that of Geographical Analysis, with the first examples of local analysis appearing in the late 1960s. Indeed, Geographical Analysis has published many of the significant contributions in this field. This paper reviews the development of local forms of spatial analysis and assesses the current situation. Following a discussion on the nature and importance of local analysis, examples are given of local forms of point pattern analysis; local graphical approaches; local measures of spatial dependency; the spatial expansion method; adaptive filtering; multilevel modeling; geographically weighted regression; random coefficients models; autoregressive models; and local forms of spatial interaction models.  相似文献

An axiomatic approach to distance is developed which focuses on those behavioral concepts of distance related to movement in space. In particular, spatial movement by behaving units is postulated to involve a choice from among some set of abstract trips in space, and implicitly, to involve the minimization of some relevant notion of trip costs. In this context, the relevant behavioral notion of distance in space is taken to be the minimum-cost distance generated by this choice process. These trip-cost concepts extend the classical notions of paths, path lengths, and shortest paths in metric spaces. Hence many of the analytical results of the paper involve extensions of classical shortest-path distance properties to minimum-cost distances. In addition to these extensions, a characterization theorem is given which specifies the possible functional relationships between trip costs and their associated path lengths. These relationships include most functional forms which are commonly employed in the literature.  相似文献

Mainstream neoclassical economic geography and its Marxist critique have largely failed to incorporate active conceptions of working class people in their explanations of the location of economic activities. Neoclassical approaches tend to conceive of workers simply as factors of location, whereas Marxist approaches primarily focus on how capital structures the economic landscape in its search for profit and frequently relegate labor to the status of "variable capital." Both approaches present Geographies of Labor. They have not really examined how workers try to make industrial landscapes. In contrast, I argue that workers have an interest in how the economic geography of capitalism is made; consequently, they seek to impose what we might call "labor's spatial fix" and so play an active role in the unevenly developed geography of capitalism. Examining how workers try to develop their own spatial fixes allows us to incorporate a more active sense of workers as geographical agents into understandings of the production of space under capitalism. Recognizing that workers' efforts to create "labor's spatial fix" are significant allows us to theorize how workers attempt to make space as an integral part of their social existence (a Labor Geography ) and so to write less capital-oriented economic geographies.  相似文献

This paper examines the role of spatial planning as a policy framework for managing rural housing within an integrated territorial development strategy. The paper focuses on the Republic of Ireland, which provides a useful case for analysing spatial planning and rural housing relationships, due to the State's recent shift towards spatial planning (formalized with the publication of the Irish National Spatial Strategy), as well as the level of housing construction that has been observed in an increasingly post-productivist countryside (triggered by counter-urbanization flows, increased affluence and demands for second holiday homes, etc.). The paper reviews all policy instruments that have been used to manage rural housing at various scales (from national strategies to local level development plans). It is argued that while spatial planning adopts an integrative vocabulary, as policy moves down the spatial scale hierarchy, multi-dimensional spatial goals are implemented through traditional, narrow land-use regulation. This often leads to rural housing being addressed in isolation from its wider social and economic context, disconnecting housing from wider rural community issues and ultimately failing to deliver a coordinated and coherent spatial policy for managing rural settlements.  相似文献

西方的中西历史及史学比较研究起源较早,是从宏观的历史文化比较发展来的。20世纪六七十年代以前,主要以宏观比较为主,并形成一般的理论模式。六七十年代,以个体的微观研究为主要特征,形成一个高潮。90年代至今是第二个高潮,以大的群体或项目为中心,出现了系统的比较,提出了新的比较理论,史学越来越成为比较的重点。西方的中西历史及史学比较理论,经历了从以近代西方为中心的东西二分法,到注重多元化的文明形态比较,再到不同文化的跨文化比较的几个发展阶段。这些变化是与学术和历史的变化密切相关的。  相似文献
