我国中心城市现代服务业发展现状与路径选择

服务业尤其是现代服务业是城市发展的战略支点,是衡量一个城市现代化水平、城市价值和城市竞争力的重要标志之一。我国中心城市近年来现代服务业虽然有了较大的发展,但是与国际中心城市相比仍有较大的差距。目前,我国中心城市已经进入现代服务业加速发展时期,国内经济平稳较好发展、新型工业化的引致需求和产业扶持政策,为中心城市现代服务业发展创造了较好的外部环境,应通过走产业融合之路、集聚发展之路、特色发展之路、创新发展之路、开放提升之路,促进现代服务业大发展,提升城市核心竞争力。

Re-examining the role of attitude in information system acceptance: a model from the satisfaction–dissatisfaction perspective

This study attempts to re-examine the role of attitude in voluntary information system (IS) acceptance and usage, which has often been discounted in the previous technology acceptance research. We extend the unidimensional view of attitude into a bidimensional one, because of the simultaneous existence of both positive and negative evaluation towards IS in technology acceptance behaviour. In doing so, attitude construct is divided into two components: satisfaction as the positive attitudinal component and dissatisfaction as the negative attitudinal component. We argue that satisfaction and dissatisfaction will interactively affect technology usage intention. Besides, we explore the predictors of satisfaction and dissatisfaction based on the disconfirmation theory. Empirical results from a longitudinal study on bulletin board system (BBS) usage confirm the interaction effect of satisfaction and dissatisfaction on usage intention. Moreover, perceived task-related value has a significant effect on satisfaction, while perceived personal value has a significant effect on dissatisfaction. We also discuss the theoretical and managerial implications of our findings.

中国城市软实力对住房价格的影响——基于主成分分析法和面板数据模型

在采用主成分分析法合成软实力综合指标构建了两阶段回归模型,运用面板数据GMM估计方法就软实力对房价的影响进行估计后发现,中国35个大中城市的软实力对城市房价均具有显著的正向作用,且这种影响从东部到西部呈现出逐渐减弱的态势。也就是说,在全国范围内,城市软实力对房价均具有显著的正向影响,且不同地区的城市软实力对房价的作用程度有所差别。由此可见,城市的人文社会因素、生态环境质量、交通区位条件对城市商品房价格的影响较为显著,对城市软实力的日益重视决定着中国城市人口的居住选择。

The Nature of Cities: The Scope and Limits of Urban Theory

There has been a growing debate in recent decades about the range and substance of urban theory. The debate has been marked by many different claims about the nature of cities, including declarations that the urban is an incoherent concept, that urban society is nothing less than modern society as a whole, that the urban scale can no longer be separated from the global scale, and that urban theory hitherto has been deeply vitiated by its almost exclusive concentration on the cities of the global North. This article offers some points of clarification of claims like these. All cities can be understood in terms of a theoretical framework that combines two main processes, namely, the dynamics of agglomeration/polarization, and the unfolding of an associated nexus of locations, land uses and human interactions. This same framework can be used to identify many different varieties of cities, and to distinguish intrinsically urban phenomena from the rest of social reality. The discussion thus identifies the common dimensions of all cities without, on the one hand, exaggerating the scope of urban theory, or on the other hand, asserting that every individual city is an irreducible special case.     

Impact of high-speed railway on urban resilience in China: Does urban innovation matter?

Based on calculating the urban resilience index from five aspects of economy, society, institutions, infrastructure, and ecology by adopting the entropy method, this study applies the time-varying DID model to systematically examine HSR's impact on China's urban resilience, on basis of which its heterogeneities and the mediating effect of urban innovation are also quantified. The findings reveal that: (1) HSR can significantly promote China's urban resilience, as supported by various robustness tests. (2) HSR can significantly improve economic and institution resilience of cities, but does not play a significant role on social resilience and infrastructure resilience, and has a negative effect on ecological resilience. (3) The driving effects of HSR on the resilience of core cities, large cities, and non-resource-based cities are more significant. (4) Urban innovation is an important channel through which HSR impacts urban resilience. The conclusions of this study can offer useful insights for China's future HSR planning and resilient cities construction.

The significance of digital data systems for smart city policy

Our planet is gradually moving towards an urbanized world. Modern urban agglomerations tend to turn nowadays into advanced information hubs supporting a smart management of dynamic urban systems. The currently popular notion of ‘smart cities’ aims to provide a new perspective for sustainable and high-performance strategies of city stakeholders in our ‘urban century’. In this context, digital information technology provides a new tool for efficient and effective management and planning of urban space, inter alia in the field of transportation, environment, public facilities or advanced service provision to citizens. This paper aims to offer, first, a concise overview of the emerging opportunities of information and communication technology (ICT) for smart urban policy; digital technology in particular, appears to provide novel pathways for modern planning strategies in smart cities. Against this background, the paper sketches out the complex force field of global urbanisation phenomena and highlights the data and information needs for strategic planning of cities (using inter alia as a framework the so-called ‘urban piazza’ strategy framework). Secondly, various new decision support tools that are currently emerging and that offer a new promising scope for handling complex urban management issues (for instance, on accessibility, congestion, safety or sustainability) are briefly presented. And finally, the potential of such digital data systems for urban management and policy is concisely illustrated by means of some recent applications in the area of smartphone data systems. The paper concludes with a discussion of the challenges ahead for urban policy, inter alia by paying attention to institutional and governance aspects of ‘big digital data’ management in urban systems.     

‘We Live on Estimates': Everyday Practices of Prepaid Electricity and the Urban Condition in Maputo,Mozambique

This article examines the transition to prepaid electricity happening in Maputo, Mozambique, in order to reflect on the contemporary geographies of urban energy infrastructure and urbanization in sub‐Saharan Africa and other cities of the South. The article draws on fieldwork and archival research conducted in 2013 and 2014, arguing that prepayment constitutes a productive juncture in the urban experience of electricity infrastructure in Maputo's postcolonial moment, not merely a neutral technology or a disciplining technique of government (as argued by some scholarship). The article examines the multiple rationalities implicated in the use of the electricity infrastructure via prepayment and the organization of urban life it engenders (and of which it is also a product) by focusing on the everyday practices surrounding prepaid electricity of urban dwellers in neighbourhoods where the ‘modern infrastructural ideal' may never be fully realized. As a result, it contributes to an understanding of the experience of urban energy in cities where ‘slum urbanism', uncertainty and provisionality are dominant aspects of the urban condition.

How did location affect adoption of the commercial Internet? Global village vs. urban leadership

We provide a framework and evidence to confront two contradictory yet common assertions: (1) new technology such as the Internet favors businesses in urban areas and (2) the Internet reduces the importance of distance for economic activity. Controlling for other factors, we show that participation in the Internet is more likely in rural areas than in urban areas. This is particularly true for technologies that involve communication across establishments. Nevertheless, talk of the dissolution of cities is premature. Frontier Internet technologies for communication within an establishment appear more often at establishments in urban areas, even with industry controls.
