出口贸易、工业碳排放效率动态演进与空间溢出   总被引:1,自引:0,他引:1  
以2003~2012年我国30个省级经济单元为研究对象,从技术进步视角出发,利用包含非期望产出的SBM模型测算各省份工业碳排放效率,运用非参数Kernel密度估计方法研究各省份出口贸易和工业碳排放效率的动态演进过程,构建空间杜宾模型进一步考察出口贸易对工业碳排放效率的影响。研究结果表明:我国东部地区的工业碳排放效率最高,依次为中部、西部地区和东北综合经济区;核密度曲线展现出口贸易整体处于上升态势,工业碳排放效率呈现双峰趋同;在考虑空间因素后,出口贸易对本地区的工业碳排放效率改善产生促进作用,但对其他地区的工业碳排放效率增长产生抑制作用,也有碍于所有地区碳排放效率的提升。  相似文献

本文考察了"机器换人"背景下工业机器人对中国制造业地区发展差距的影响.研究结果表明:由于工业机器人与低技能劳动的替代关系,其应用对地区劳动力比较优势带来一定的冲击,促进了非技术密集制造业的分散化发展,因而对非技术密集行业存在后发优势;但由于工业机器人与高技能劳动的互补关系,其应用巩固了先发地区的技术、人才优势,促进了技术密集制造业的集聚发展,因而对技术密集行业存在先发优势.通过异质性检验发现:工业机器人对非技术密集制造业的分散作用更多存在于华东和西北地区,而对技术密集制造业的集聚作用更多集中在华北、中南和西北地区;在机器人的作用下,非技术密集制造业的分散趋势主要由其行业自东向中、西部转移所致,而技术密集制造业的集聚趋势主要与其行业重心向东部地区收缩有关.  相似文献

“三元”城镇化对服务业增长的影响   总被引:1,自引:0,他引:1  
快速崛起的城镇化为服务业的发展提供了必要的基石。然而,对服务业增长产生深远影响的城镇化绝不仅仅局限于以城镇人口占比所表征的城镇化。本文提出“三元”城镇化概念,并把“三元”城镇化定义为“外延式”城镇化、“内涵式”城镇化以及“网络式”城镇化。本文从理论上考察了“三元”城镇化影响服务业增长的传导机制。本文随后基于中国1999~2013年27个省份的面板数据,运用增长模型、比重模型和效率模型系统检验了“三元”城镇化对服务业增长的影响,研究表明,“外延式”城镇化和“内涵式”城镇化均从服务业规模、产业比重和劳动生产率三个方面显著促进了服务业的增长,“网络式”城镇化仅仅促进了服务业规模的扩张。“内涵式”城镇化和“网络式”城镇化对知识密集型服务业增长的促进作用更大,“外延式”城镇化则对非知识密集型服务业增长的促进作用更大。“三元”城镇化均显著促进了东部地区知识密集型服务业的增长,同时拉大了中西部地区与东部地区知识密集型服务业增长的差距。  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
