随着我国社会经济的快速发展,国内大型城市"职住分离"程度持续增大,深圳市作为一线城市,人口规模大,经济发展迅速,同样存在一定程度的"职住分离"状况,产生了通勤过剩现象.以深圳市为研究对象,运用线性规划模型和空间分析等方法对深圳市多源全样本人口数据进行分析,计算深圳市过剩通勤指标,分析深圳市过剩通勤空间特征.研究结果表明深圳市过剩通勤处于较高水平,但整体通勤消耗率中等,城市过剩通勤存在空间分异情况.本研究可服务于城市规划和城市交通规划,对评价和优化深圳市职住空间提供重要的参考,同时为深圳市改善城市交通问题、合理制定规划政策提供重要依据.  相似文献

在制度转型和城市空间扩张背景下,研究城市居民住房成本与通勤成本空间互动关系及群体需求差异,能够为城市住房政策和交通规划管理提供决策依据。基于《2016年天津市交通与住房调查问卷》数据,构建住房需求函数,探讨不同类型城市居民住房成本与通勤成本在城市空间结构中的互动关系。结果显示:住房成本与通勤成本显著负相关,但不同类型城市居民对二者之间的替代关系存在较大差异,其中住房补贴、通勤方式及职业类型等属性对居民住房成本与通勤成本之间替代关系具有较大影响。因此,从引导住房消费合理分层、优化公共交通体系功能层次及布局、推进城市副中心建设等方面提出政策建议,促进城市居民职住平衡。  相似文献

北京市职住分离及其影响因素分析   总被引:2,自引:0,他引:2  
采用北京交通发展研究中心开展的家庭居民交通行为调查(2013年),并结合第三次全国经济普查数据,讨论了家庭收入、房屋类型、通勤方式等6个变量的职住分离特征及其差异,用多元回归分析的方法系统分析各变量同通勤时间之间的关系。结果显示:(1)随着收入的增加,通勤时间和距离呈上升趋势;家庭收入在居住区位选择、房屋类型、通勤方式以及通勤距离和时间等方面具有决定性作用。(2)租住房屋、单位房、经济适用房和商品房的通勤时间和距离依次呈上升趋势,住房制度的历史路径依赖仍然存在,用地市场化驱动的城市空间结构趋向分散,职住空间重构具有一定的一致性。(3)通勤时间基本呈现公司员工商业服务业事业单位自由职业的格局。(4)通勤时间和距离与职住比、通勤方式、性别、职业类型、房屋类型、年家庭收入等变量线性关系显著,同年龄、就业密度线性关系不显著。(5)随着职住比的增加,通勤时间呈现先下降后上升的"U"型结构。  相似文献

便宜、快速、方便的大城市公共交通系统与长时间、长距离通勤、上下班高峰期"交通拥堵"并存是目前中国大城市发展中面临的主要城市问题。居住与就业的空间失配(职住失衡)被认为是导致以上问题的重要原因之一。以就业可达性方法来测度城市居民的居住与就业(职住)空间关系,并以广州为例,揭示公共交通系统网络下,中低收入人群职住空间关系的特征和差异,以为城市公共住房、公共交通、产业等规划和政策的制定提供有益参考。基于广州案例有两个发现:第一,低可达性人数多于高可达性人数。其中,低可达性"蓝领"较"粉领"多,且其主要居住在非中心城区;而居住在中心城区的高可达性"粉领"人数较"蓝领"多。第二,与国外大城市相似,居住在中心城区能给广州中低收入人群带来一定的就业可达性优势。不同点在于,居住在广州非中心城区的高可达性"蓝领"人数多于居住在中心城区的高可达性"蓝领"。  相似文献

This paper outlines the ICT statistical developments that the ABS has undertaken over recent years. These developments have been on both the supply side (ICT industry) and the demand side (use of IT by sector). The content of ABS ICT surveys has changed significantly over the last few years and are expected to develop further in line with industry changes and emerging policy needs.
Recent developments in household collections have been the inclusion of IT use questions in the 2001 Census of Population and Housing and in various ABS social surveys such as Children's Participation in Culture and Leisure Activities. Annual business IT use surveys are now conducted and include topics such as Internet commerce and IT security. Biennial ICT industry surveys are conducted to provide data on ICT production, imports and exports, ICT industry employment, performance and structure information. An Internet activity survey is run every six months and provides regional Internet access details and infrastructure details on Internet service providers.
A major development for 2002–03 will be the compilation of an ICT satellite account. ABS intends to produce an ICT Information Development Plan to guide its future statistical development work in the ICT field.  相似文献

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support.  相似文献

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.  相似文献

NGOs in Bangladesh have been recognized as effective change agents in the socio-economic arena throughout the world. Their contributions in micro credit, non-formal education and primary health care are widely known. NGOs play a significant role in society. NGO accountability, as a result, has become a critical issue. NGO accountability in Bangladesh has been examined here in relation to patrons, clients and themselves. Of the three relationships only accountability to patrons is in a near satisfactory state. Accountability to clients is handicapped by lack of opportunities of beneficiaries to participate meaningfully in NGO policy making. Accountability to themselves is adversely affected due to the adherence to a strictly hierarchical system and the influence of founding and charismatic NGO leaders.  相似文献

There has been much discussion regarding the possible decline and weakening of national systems of human resource management (HRM). Yet, culture and institutions are often cited as the major stumbling blocks to this outcome. Such constraints may dissipate in the analysis, particularly if ‘regional clusters’ are considered where geographic and cultural closeness and ‘openness’ to similar economic pressures exist. In such cases, it might be postulated that convergence in HRM will occur. We argue that China, Japan and South Korea represent such a cluster. This article examines these countries, to see if a degree of convergence is taking place and if it is towards an identifiable ‘Asian’ model of HRM. A model of change is presented that distinguishes between levels of occurrence and acceptance. Details of the development and practice of HRM in each country are then set out. The article ends with a discussion and implications section and a brief conclusion.  相似文献

We have considerable understanding of the obstacles that women engineers encounter and the reasons that they leave the field, but we know less about what enables them to remain. Adopting an interpretivist approach, this article examines how a group of British women engineers in two FTSE 100 companies account for “staying on” in their male‐dominated work settings. We delineate four specific forms of help that facilitate women's retention in the field. We argue that exposure to help leads to women developing a habitus that enables them to continue working in engineering. To conclude, we draw on our findings to outline HR practices that will facilitate supportive relationships in the workplace and pave the way towards developing more positive organisational climates.  相似文献

This paper focuses on the fashion industry, one characterised by issues such as dramatic shifts in the scale and power of major retail buyers in the market, the advent of retailer own brands, and the nature of sourcing and supply chain decisions, issues that are increasingly global in nature. The aim of this research is to explore the nature of relationships between UK high street multiple fashion retailers and their contracted suppliers, many of whom are entrepreneurial firms by most definitions of the term. Four core themes emerge from the literature and provide a framework for the research, namely, power, process, partnership, and people. The research approach was qualitative, and conducted over a period of twelve months. The paper ends with an agenda for future research.  相似文献
