南通工业经济增长影响因素协整分析

运用基于VAR模型的动态经济计量分析方法,选取劳动、资本、能源及科技进步作为影响南通工业经济增长的四个因素,建立工业经济增长与上述影响因素关系的多变量协整模型,进行长期均衡和短期波动的实证分析。     

天然气消费与经济增长的动态均衡与因果关系分析

本文运用协整理论和Granger因果关系检验两种日益流行的计量经济分析技术,考察了1991～2011年期间我国天然气消费与经济增长之间的动态均衡关系和因果关系,协整分析结果表明：我国天然气消费与经济增长之间存在长期的均衡关系,进一步考虑建立误差修正模型来研究两者之间的短期情况,结果表明天然气消费与经济增长之间也存在着短期动态均衡关系。为了更好地观察天然气消费和经济增长之间的短期动态关系,本文考虑了脉冲响应函数,研究结果显示：天然气消费量的随机扰动项对我国的经济增长正向冲击作用先缓慢下降后上升的趋势;最后,Granger因果性检验表明,我国天然气消费对经济增长有着显著的促进作用,而经济增长对天然气消费的影响并不显著,原因在于我国的经济发展存在“能源高耗”及“能源依赖”的现象。     

通货膨胀传导机制研究——基于货币供给和经济增长的视角

通货膨胀管理是宏观经济的重要内容,通货膨胀、货币供给和经济增长之间互相影响、互相制约。本文利用中国2005年1月～2010年3月度数据构建模型分析,得出结论:(1)短期影响消费者物价指数的因素主要是国内生产总值增长率,长期控制消费者物价指数上涨的要素主要是货币的供给;(2)宏观经济形势稳定条件下通货膨胀、货币供给和经济增长之间具有长期协整关系;(3)消费者物价指数对自身的波动具有较强的累积效果,经济增长贡献了消费者物价指数波动的55%,而广义货币的这一比例仅为18%;(4)中国货币收入的真实需求弹性为1.152,这一数据远高于发达国家的水平。文章最后给出了相应的政策性建议。     

中国社会保障支出对收入分配差距与经济增长的动态冲击效应

本文从社会公平和经济效率双重视角出发,利用1978—2018年时间序列数据,应用基于马尔科夫链蒙特卡洛模拟的带有随机波动的时变参数向量自回归模型,分析了中国自改革开放以来社会保障支出对收入分配差距与经济增长的动态冲击效应。结果表明：社会保障支出始终存在逆向的收入分配效应与正向的经济增长效应,且随时间的推移均表现出了较强的动态时变性,两者波动趋向同步,呈现出近似倒U型的非线性动态变化过程;社会保障支出对收入差距的逆向调节效应具有“见效快”的特点,短期影响效应较强,而对经济增长的促进作用存在时间滞后性,中期影响效应较强;在中国社会保障改革发展的不同阶段,社会保障支出收入分配效应与经济增长效应的大小与持续时间均存在显著差异,随着社会保障发展阶段的变迁,整体呈现出了影响效应不断增强,持续时间不断变长的演变规律。     

电力产业链与宏观经济波动均衡关系研究

本文利用电力产业链20种产品增长率数据进行二项分布检验,建立与GDP增长率序列的差分VAR模型,实施协整检验。结果证实20种产品的波动具有一定系统性,产业链与宏观经济波动存在逆向长期均衡,它们分别对均衡偏离进行同进同退的短期调整。这反映了中国经济的传统增长方式面临现实约束——增长方式低效率本身,产业链大起大落源于均衡关系的波动和调整方式。目前,产业链高速增长趋势的转折在即。     

我国区域经济增长与能源利用效率改进的动态演化机制研究——基于省域面板数据协整模型的实证分析

本文以1989～2005年我国31个省域面板数据为对象,采用空间计量模型及相关性指数以及面板单位根及协整检验,得出结论表明:各省域能源利用效率在空间分布上具有明显的空间依赖性,并非表现出完全随机状态;空间相关性指数极其显著且历年波动很小,表明我国省域能源效率之间内在作用机制长期存在且相互影响;各省域能源效率与经济增长、产业结构、人口数量、技术进步等之间存在长期稳定的均衡关系,且长期均衡具有显著的短期修正和波动效应。     

能源消耗与经济增长的关系分析——基于辽宁省时间序列数据万寿义

辽宁省是能源资源消耗大省，其经济增长对能源消耗的依赖程度一直较高。通过采用协整回归分析方法、误差修正模型、格兰杰因果检验对辽宁省的能源消耗和经济增长之间的关系进行实证分析后发现：能源消耗与经济增长两者之间存在长期动态关系；当两个变量的短期波动与长期均衡发生偏离时，非均衡状态将被拉回到均衡状态；能源消耗对经济增长具有单向格兰杰因果关系。研究结果意味着辽宁省要保持经济的持续稳定增长，必须要有充足的能源供应作为有力保障，但近几年来辽宁省的能源供给和经济增长之间的矛盾日益突出，故辽宁省应该从能源需求和能源供给两个方面出发，通过强化节能意识、调整能源结构、提高能源利用效率和加强科技节能研发力度等来进行节能减耗。     

南通经济增长、能源消费与环境污染关系的实证分析

本文运用基于VAR模型的动态经济计量分析方法,分析南通经济增长与能源消耗、环境污染三者之关系,建立南通经济增长与上述两因素的多变量协整模型,进行南通经济增长与能源消耗、环境污染的长期均衡和短期波动的实证分析。     

股市波动对利率期限结构长短期冲击分析

本文选取了2004-2008年的中国国债数据，在Nelson-Siegel模型的基础上，引入股市收益率，股市波动率以及GDP对水平因子、斜率因子以及曲率因子进行时间跨度由长到短的时间序列分析。分析结果表明宏观因素没有明显相关性。利用工具变量法,发现短期内曲率因子的波动可以被三因子的滞后以及股市波动良好解释，股市收益率对水平因子有着显著冲击，股市波动率对水平因子短期有着显著负影响，而长期影响为正。     

中国R&D人力资源结构与经济增长的关系研究

技术进步是经济长期增长的源泉,而研究与发展活动是整个科技活动的核心。文章利用单位根检验、协整检验和误差纠正模型,基于中国1991-2010年的年度时间序列数据的实证研究发现,应用研究人力资源投入与经济增长之间不存在长期均衡关系,基础研究人力资源投入和试验发展人力资源投入与经济增长之间存在长期均衡关系,不存在短期关系。但格兰杰因果检验表明,试验发展人力资源投入与经济增长之间不存在因果关系,基础研究人力资源投入与经济增长之间存在前者到后者的单向因果关系。     

Development in Information and Communications Technology (ICT) Statistics at the Australian Bureau of Statistics

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.     

Value at Risk in the Suburbs: Eminent Domain and the Geographical Politics of the US Foreclosure Crisis

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.     

Towards a Theory of Serendipity: A Systematic Review and Conceptualization

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.     

Accountability of NGOs in Bangladesh A critical overview

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.     

Towards an Asian model of human resource management? A comparative analysis of China,Japan and South Korea

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.     

The Creation of the Office for National Statistics

A new Office for National Statistics was created in the United Kingdom in 1996 following a series of developments designed to strengthen the relevance and integrity of statistics. This paper describes these fundamental changes and sets out a blueprint for future progress. It also sets current developments in the United Kingdom in an historical and international context.     

What helps? Women engineers' accounts of staying on

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.

Supply Chain Strategies in the UK Fashion Industry—The Rhetoric of Partnership and Realities of Power

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.
