城市空间的生产方法论探析 总被引:1,自引:0,他引:1
“空间的生产”是新马克思主义城市学派的核心概念.哈维在发扬“空间的生产”理论并将其用于城市问题研究上具有代表性.其城市空间分析的方法论特点有三:立足于自身问题;自由和富有批判性;阶级分析和文艺分析相结合.国内案例研究反映出微观与宏观、时间与空间尺度结合的重要性. 相似文献

Maintaining ecosystem continuity has become a central element in spatial planning policies. Several authors acknowledge the environmental, also known as landscape, fragmentation due to human action as one of the main causes which have negative effects on biodiversity. The phenomenon consists of the transformation of larger patches of habitat in smaller ones, or fragments, which tend to be more isolated than in the original condition. It is extremely evident in urban areas, including settlements and various transport and mobility infrastructures, whose main ecological effects include loss of habitat, increased mortality of plants, and isolation of animal and vegetal species. In this paper, we assess landscape fragmentation dynamics of six landscape units belonging to two European regions, i.e. Sardinia in Italy (from 2003 to 2008), and Andalusia in Spain (from 2005 to 2009). We developed on three indices: the Infrastructural Fragmentation Index (IFI), the Urban Fragmentation Index (UFI), and the Connectivity Index (CI). We found that coastal areas generally suffer from an higher pressure due to the demand of longer or faster transport infrastructures and new settlements and less fragmented areas tend to show the most relevant dynamics in a sort of convergent pattern. Even though landscape fragmentation and connectivity are intuitively complementary phenomena, in this paper we did not found any statistical evidence of this associative property. 相似文献

This paper provides an understanding of the widely-documented retirement-consumption puzzle from the perspective of food consumption. Exploiting the mandatory retirement age cut-off for public-sector male employees in urban China to obtain a source of exogenous variation in their retirement status, this paper identifies the causal impacts of retirement on four major aspects of their food consumption: food expenditure, time spent in food acquisition, the quantity and quality of food consumed. Based on data from the China Health and Nutrition Survey, our fuzzy regression-discontinuity analysis finds that, consistent with the retirement-consumption puzzle, retirement reduces elderly males’ total food expenditure by 49–55%. However, retirement barely changes the quantity of food they consume (measured by total calorie intakes). Further analysis suggests that elderly males substitute time for money in food acquisition upon retirement, which helps to reconcile the differential impacts of retirement on food expenditure and food consumption. Finally, retirement greatly changes elderly males’ diet structure. They consume significantly less food with animal origins (and thus less fat and protein) and more grains (and thus more carbohydrate) upon retirement, which undermines their diet balance by the standards provided by the Chinese Nutrition Association. 相似文献

The study conducts a legal and economic analysis comparing the new Consolidated Text of the Land Use Act of 2008 (Texto Refundido de la Ley de Suelo) and the Land Law 6/1998, April 13 now repealed. The study examines various articles contained in the new law and the old law. Although the study analyzes every title in both laws, it focuses on Title III regarding valuations for the expropriation of property owners. 相似文献

This article stresses the importance of urban planning interventions on real estate office markets in an environment increasingly characterized by globalization processes and progress of information and communication technologies, leaving behind the traditional influence of more market-related variables spread abroad vast literature. It contends that a better indirect control exerted by municipal authorities may launch the performance and characteristics of these markets. Within this scope, an innovative methodology and model are proposed, aimed at assisting municipal decisions in the definition of strategic policies concerning location or relocation of offices, and respective influences over rents. This methodology and this model have a flexible ongoing character that fits the anytime concrete features of local office markets. They are applied, as a case study, to the office market of Oporto city (Portugal). Implications for urban policy are inferred and generalized from this analysis. 相似文献

The purpose of this article is to investigate the central government redistribution policies across local governments that affect regional agglomeration. Though full agglomeration is efficient, in many cases factor mobility is imperfect and the full agglomeration is not realized. This article analysed whether or not the central government should adjust the distribution of populations through local governments. The result is as follows: If individuals are relatively mobile, the central government can improve the aggregate income. In this case, when the private production and public sector are small, the central government should transfer from the productive regions local government to low-productive regions. 相似文献

What tenure security? The case for a tripartite view 总被引:1,自引:0,他引:1
In the face of advancing urban informality in the developing world there appears to be increasing consensus that tenure security is an important engine driving settlement development. This has, however, not led to a consensus about what tenure security exactly entails. In both theory and policy, the idea of tenure security for low-income settlement dwellers is encountered in three distinct forms: tenure security as perceived by dwellers, tenure security as a legal construct and de facto tenure security. The main argument of this paper is that much controversy that surrounds the debate arises precisely as a consequence of the indiscriminate use of these different kinds of tenure security. To address this problem, a tripartite conceptualization of tenure security that incorporates its three constituent components (perception, de jure, de facto) and clarifies their interrelations is presented. 相似文献

Traditional models of economic development such as economic base and urban revitalization models have been found wanting. Both models rely on expert-based assessments of local development needs. More recent approaches call for a stronger focus on local development needs and resident skills as the basis for designing development strategies. One such neighborhood-based approach to development is presented in this paper. Its initial step was a survey of 444 households representing 1398 residents conducted in the Hamilton Hill and Vale neighborhoods of Schenectady, New York a 'downsized' community of about 65,000 residents in the Capital District of New York State. Survey results show a strong need for recreation, childcare, a grocery store, care for the elderly and home repairs. Residents' self-assessed job skills and interests appear to be well suited to meet these needs. Yet despite these promising results, barriers to neighborhood-based development persist. These barriers reiterate the long history of isolation prevalent in US inner city neighborhoods. Two issues are particularly characteristic of the barriers that continue to keep urban neighborhoods isolated from their larger context. They are: (1) a lack of effective communication between local residents and decision makers; and (2) a lack of valuation systems that properly assess the value of social and environmental context and their contributions to local development. 相似文献

In many Australian cities the response to drought has included the imposition of mandatory constraints over how water is used by households, often termed ‘water restrictions’. A similar rationing approach has been witnessed in California’s recent drought. The aim of water restrictions is to slow the depletion of water storage but restrictions have also been criticized for the costs they impose on specific water users. In order to gain insight into the potential magnitude of the cost of water restrictions, this study uses a choice experiment to investigate the non-market values for specific attributes associated with the outcomes of drought restrictions. This information was sought to understand the community’s willingness to pay for attributes related to the extent, frequency and duration of water restrictions. The article reports a latent class choice model for a major city in eastern Australia and investigates heterogeneity in preferences towards increasing water availability during drought. This study departs from the existing literature by conducting the choice experiment in a context where water supply is relatively abundant. This unique framing of the choice experiment allows for a useful comparison with existing studies and also raises challenges about the interpretation of the data for planning purposes. 相似文献
