19世纪英国城市现代化初探

城市现代化是城市化发展的高级阶段。19世纪的英国不仅是世界上第一个城市化国家,而且率先在城市现代化方面做出新的探索。首先在城市物质环境方面进行了巨大的改革,从城市街道的规划改造,到居民住宅的建筑规范,从居民私人空间的营造,到城市公共空间的建设,使城市的物质环境有了极大的改善。其次,在城市的管理方面也进行了全面探索,使城市管理摆脱了中世纪的寡头统治,进入到民主监督与管理的时代。由此,使城市的发展在经历了第一个阶段的数量扩张后,进入到了质量的增长时期,即向城市现代化方向迈进。     

The Concept of Urban Hibernation

Today, as a result of fast-paced societal transformations, many small towns face severe developmental challenges and an uncertain future. Departing from the broader theory of developmental disequilibrium, we launch the concept of urban hibernation to explain the process of periodic small-town regress. The concept—along with its key stages and turning points—is presented to the background of urbanization processes encountered in Poland. At the same time, the focus on small towns offers an alternative and more context-sensitive explication to eclectic development models inherent to larger cities. As such, we argue that the concept of urban hibernation is apt to serve as a more precise research and planning tool in the context of small towns, and particularly in the critical moments of rise and recession. By applying a historical perspective, we address the importance of proper identification of the various and ever-changing city-forming factors, including their role for spatial planning at different scales. Urban hibernation should thus be considered as an intrinsic part of the geographic environment, which, due to the volatility of its socio-economic components, transcends the traditional rural–urban divide. Our conceptual contribution may thus serve as a background for a fuller understanding of the variability and dynamics of intra-urban structures.     

Urban shrinkage: an unspoken challenge of spatial planning in Russian small and medium-sized cities

Shrinkage since the collapse of state socialism has been evident in many Russian cities, especially in small and medium-sized (SMS) ones. The Russian state, de jure, has been promoting the idea of self-governance; thereby, urban municipalities ought to develop and adopt own planning decisions to cope with various challenges, including those related to depopulation. The current research focuses on planning responses to urban shrinkage. It aims at understanding how the phenomenon is conceptualized in the planning documents of Russian SMS cities and what solutions are proposed to cope with it in the conditions inherited from the Soviet times housing and infrastructural deficit. The empirical evidence for the analysis is drawn from over 70 SMS cities located in Central and Southern Russia. Results state that despite obvious and persisting urban shrinkage, most of the reviewed documents ignore or underestimate the phenomenon. Instead of suggesting flexible solutions, which would help overcome the shortage of urban infrastructure not aggravating shrinkages’ effects in the cityscape, long-term spatial plans are being developed with hope for future growth proposing measures that contribute to the intensification of urban sprawl and fragmentation.     

Alonso and the Scaling of Urban Profiles

How urban characteristics change with total population, their scaling behavior, has become an important research field since one needs to better understand the challenges of urban densification. Yet urban scaling research is largely disconnected from intra-urban structure, and this seriously limits its operationalization. In contrast, the monocentric model of Alonso provides a residential choice-based theory to urban density profiles. However, dedicated comparative static analyses do not completely solve how the model scales with population. This article bridges this gap by simultaneously introducing power laws for land, income and transport cost in the Alonso model. We show that the equilibrium urban structure of this augmented model matches recent empirical findings about the scaling of European population density profiles and satisfactorily represents European cities. This result is however not compatible with the observed scaling power of housing land profiles, and challenges current empirical understanding of wage and transport cost elasticities with population. Our results call for revisiting theories about land development and housing processes as well as the empirics of agglomeration benefits and transport costs.     

Polycentrism as a Multi-Scalar Relationship Between Urban and Rural Areas: The Case of Portugal

This article introduces a reflective analysis of polycentrism. Since the 1990s, polycentrism has provided the foundation for countless spatial planning policies in Europe. Most studies highlight the importance of cities and towns as the principal nodes for regional development. This article discusses whether polycentrism is the best planning solution for managing the imbalances and relationships between urban and rural areas. Empirically, it will focus on the polycentric discourse that has recently gained strength in Portugal, by evaluating the national spatial planning policy programme and its consequences for regional development. It will make a comparative analysis between the national spatial development perspective proposed by the programme and certain sociological findings that characterized the rural areas caught out between urbanization and marginalization. This will be illustrated with research on the Alentejo region, one of the largest rural areas in Portugal.     

Prospects for the Rural‐Urban Fringe in Australia: Observations from a Brief History of the Landscapes around Sydney and Adelaide

Despite being a major site of recent population growth and, arguably, a key arena for sustainability concerns, the rural‐urban fringe has received relatively little attention in the literature concerning Australian cities and urban policy. To address this shortcoming the authors review post‐World War II efforts to plan the rural‐urban fringes of Sydney and Adelaide and find a number of issues for contemporary policy‐makers. First, the fringe is becoming increasingly complex due to multi‐faceted demographic change, a broadening economic base and demands for better environmental management, all within the context of an evolving understanding of sustainability. Second, water resource management, partly under the auspices of integrated natural resource management, is assuming a much higher priority than in early fringe planning endeavours, which emphasised urban containment, agricultural land protection and landscape conservation. Third, and partly as a consequence of this shift of priorities, there is also evidence of changes to the nature and focus of policy tools used in the fringe, with land management concerns now cutting across traditional land use planning. Finally, and fundamentally, these observations raise questions about how future governance of the fringe should be organised. Together these four themes pose an enthralling series of challenges for policy‐makers for which much more research and discussion are needed.

Urban geography and protest mobilization in Africa

Urbanization has long been seen by scholars and policymakers as a disruptive process that can contribute to social and political unrest, yet there is little cross-national quantitative empirical research on the topic. In this paper we provide a comprehensive analysis of the links between urban geography and the incidence of protests (i.e. demonstrations, riots and strikes) in African countries since 1990. In contrast to previous studies, we are careful to distinguish between urban population scale effects, urban population ratio effects, population rate-of-change effects and urban population distribution effects. We also provide an explicit test of the long-standing hypothesis that ‘over-urbanization’ increases the risk of civil unrest. Employing multilevel negative binomial models that control for key political and economic variables we find that urban population size and the number of large cities in a country are both positively and significantly associated protest incidence. By contrast, we find that a country's level of urbanization is negatively associated with protest incidence and reject the over-urbanization hypothesis: higher levels of urbanization are associated with less frequent protests at all income levels. We find no evidence that the pace of urban population growth or urban primacy significantly influence protest mobilization. In sum, our results provide a nuanced picture of the relationship between urban geography and protest incidence that challenges conventional wisdom and contemporary hyperbole about the dangers of ‘rapid urbanization’ in Africa in particular, and developing countries more generally.     

How much does urban location matter for growth?

This paper analyses the effect of location characteristics on urban growth using regression cubic splines. Our empirical analysis shows that in Spain, differences in accessibility to major urban centres and geographic isolation help explain differences in population growth rates across municipalities between 2001 and 2014. Moreover, even though physical proximity to large cities is usually assumed to be closely related to the attractiveness of a municipality, we found that urban population growth is even more related to the joint effect of distance to major centres and agglomeration. In this respect, there seems to be a threshold from which agglomeration diseconomies come into play such that a greater proximity to major cities and/or being localized within a more densely populated area goes against local growth.     

Empirical Urban Theory for Archaeologists

I review several bodies of empirical urban theory relevant to the archaeological analysis of ancient cities. Empirical theory is a type of “middle-range theory” (following Robert Merton): sets of concepts and methods that are less abstract, and have greater empirical content, than high-level social theory. The categories of theory reviewed here include environment-behavior theory, architectural communication theory, space syntax, urban morphology, reception theory, generative planning theory, normative theory, and city size theory. Most of these approaches originated in the fields of architecture, planning, and geography, and they directly link the urban-built environment to the actions of people within cities.

Increasing returns to scale in the towns of early Tudor England

Abstract

Urban agglomeration economies make cities central to theories of modern economic growth. There is historical evidence for the presence of Smithian growth and agglomeration effects in English towns c.1450-1670, but seminal assessments deny the presence of agglomeration effects and productivity gains to Early Modern English towns. This study evaluates the presence of increasing returns to scale (IRS) in aggregate urban economic outputs—the empirical signature of feedbacks between Smithian growth and agglomeration effects—among the towns of 16th century England. To do so, we test a model from settlement scaling theory against the 1524/5 Lay Subsidy returns. Analysis of these data indicates that Tudor towns exhibited IRS—a finding that is robust to alternative interpretations of the data. IRS holds even for the smallest towns in our sample, suggesting the absence of town size thresholds for the emergence of agglomeration effects. Spatial patterning of scaling residuals further suggests regional demand-side interactions with Smithian-agglomeration feedbacks. These findings suggest the presence of agglomeration effects and Smithian growth in pre-industrial English towns. This begs us to reconsider the economic performance of Early Modern English towns, and suggests that the qualitative economic dynamics of contemporary cities may be applicable to premodern settlements in general.     

Reforms,Globalization, and Urban Growth in China: The Case of Hangzhou

Chinese cities have experienced unprecedented growth and restructuring during the reform period. This study by two geographers examines the rapid growth of urban population in the relatively typical large city of Hangzhou (one of China's historical capitals), and investigates underlying factors by highlighting the significance of reforms and globalization in the growth of Chinese cities. The authors also discuss problems that Hangzhou (currently with ca. 4 million inhabitants) faces in coping with rapid urban growth and restructuring. They argue that "control" and "management" approaches to urban growth have limitations in China's transitional cities, and that the gradual process of reform is incompatible with the nature of urban planning in China.

The Dynamics of Growth in a Regional Urban System: Southern Ontario, 1851–1971

This study has four objectives: (1) to describe the dynamics of growth in the urban system of southern Ontario over the period from 1851 to 1971; (2) to determine whether this system has evolved in accordance with the Gibrat process of growth; (3) to contribute to the debate on the relationship between city-size distributions and economic development; and (4) to offer some technical and definitional suggestions with regard to the rank-size rule, urban primacy, and the measurement of population concentration. Related Canadian studies covering similar time periods are those of Simmons (1974), who has analysed the growth of larger cities (10,000 and over) at the national scale, and Bannister (1975), who has described the extent of spatial autocorrelation in the growth rates of southern Ontario's incorporated centres. Like Simmons and Bannister we are less concerned with the fortunes of particular places than with the response of the urban system as a whole to expansionary forces. We are centrally concerned with the phenomenon of differential growth (Borchert, 1967; Ward, 1971, pp. 11–49; Muller, 1976, 1977). The fact that towns grow at different rates implies changes in the frequency distribution of city size and in the level of concentration of the urban population. These changes, in turn, have interesting consequences for urban systems theory.     

Suburbanization and sprawl in post-socialist Belgrade and Sofia

The goal of this research is to examine the processes of suburbanization and sprawl in two post-socialist capital cities in Southeast Europe – Belgrade, Serbia and Sofia, Bulgaria. Our analysis begins with a survey of relevant historical developments in the two cities, which illustrates the impact of major political, economic and social drivers on urban development processes and form. We follow this with an empirical study aimed at identifying contemporary features of peri-urban processes occurring in the two cities. Specifically, we explore spatial patterns, general population trends and changes in urban densities. Our study confirms earlier observations by other researchers that processes of suburbanization are occurring in Belgrade and Sofia. Yet this research goes further and emphasizes the specific combination of conditions inherited from the era of state socialism and the features of South-east European urban culture. Thus regarding the form of urban expansion, we observe relatively weak trends of sprawl with strong local specifics. On this basis, we discuss our empirical results with the objective of identifying the specifics of studied processes in Belgrade and Sofia as a grounds for the articulation of an appropriate policy framework.     

Urban Regeneration in the Brazilian urban policy agenda

This article aims to highlight the main arguments that sought to justify the incorporation and legitimization of Urban Regeneration in the urban policy agenda in Brazil. It shows how the convergence between different and even conflicting propositions related to urban development provided ideological support to the construction of discourses in which urban regeneration is portrayed as beneficial to society as a whole, and how recent international ideas on urban development were incorporated in urban policies of contemporary Brazil, considering our local socio-economic and political environment, planning tradition and regulatory frameworks. The focus will be on Rio de Janeiro and particularly São Paulo given the key role these two cities play in defining urban policy paradigms, guiding government agendas and exporting regulatory models to other parts of Brazil.

HOW DO DIFFERENCES IN PROPERTY TAXES WITHIN CITIES AFFECT URBAN SPRAWL?*

ABSTRACT We develop a duocentric‐city model and show that the ratio between the property tax in the suburbs and in the center has an ambiguous impact on the size of the city. We test this model by using a dataset of effective property tax rates which we developed using GIS techniques for central cities and suburbs in 445 urbanized areas. Results from the empirical analyses suggest that a lower property tax rate in the suburbs as compared to the central city is associated with more expansive urban growth and a greater level of decentralization of population and employment.     

Territorial development,planning reform and urban governance: the case of Ireland’s second-tier cities

The increased emphasis within Europe on the role of second-tier cities has implications for the ways in which these urban centres are considered within national spatial planning strategies. In centralized, monocentric states such as Ireland, there has been a general ambivalence towards urban policy for cities outside the capital city, and historically, this has prevented the development of a strong, diversified urban hierarchy undermining prospects for balanced regional development. This paper examines the extent to which a new found emphasis on Ireland’s second-tier cities which emerged in the ‘Gateways’ policy of the National Spatial Strategy was matched by subsequent political and administrative commitment to facilitate the development of these urban centres. Following a discussion of the position of second-tier cities in an international context and a brief overview of recent demographic and economic trends, the paper assesses the relative performance of Ireland’s second-tier cities in influencing development trends, highlighting a comprehensive failure to deliver compact urban growth. In this context, the paper then discusses the implications of current development plans for the second-tier cities and proposals for Irish local government reform for securing compact urban development.
