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

Vendor Managed Inventory (VMI) involves the vendor making the replenishment decision for products supplied to a customer based on various inventory and supply chain policies. Information sharing between supply chain members is required in VMI. Sometimes VMI decisions are delayed and/or the information shared is inaccurate. This research examines the effects of information delay and accuracy, and the sharing of sales and forecast information in a VMI environment facing stationary and nonstationary demand. The simulation experiments show the impact of information delay, information inaccuracy, and information sharing on a variety of performance measures, including inventory levels and fill rates.  相似文献

The primary purpose of this paper was to empirically explore some of the reasons that logistics has become more important, or salient, in comparison to other functions within the firm. A survey of 296 managers across multiple industries in the U.S. found logistics becomes more important within the firm when the industry increases in uncertainty, when there is an emphasis on time‐based competition, when there is greater adoption of information technology, and when there is an emphasis on cross‐functional integration.  相似文献

Recently, much of the research into the relation between market values and accounting numbers has used, or at least made reference to, the residual income model (RIM). Two basic types of empirical research have developed. The “historical” type explores the relation between market values and reported accounting numbers, often using the linear dynamics in Ohlson 1995 and Feltham and Ohlson 1995 and 1996. The “forecast” type explores the relation between market value and the present value of the book value of equity, a truncated sequence of residual income forecasts, and an estimate of the terminal value at the truncation date. The analysis in this paper integrates these two approaches. We expand the Feltham and Ohlson 1996 model by including one‐ and two‐period‐ahead residual income forecasts to infer “other” information regarding future revenues from past investments and future growth opportunities. This approach results in a model in which the difference between market value and book value of equity is a function of current residual income, one‐ and two‐period‐ahead residual income, current capital investment, and start‐of‐period operating assets. The existence of both persistence in revenues from current and prior investments and growth in future positive net present value investment opportunities leads us to hypothesize a negative coefficient on the one‐period‐ahead residual income forecast and a positive coefficient on the two‐period‐ahead residual income forecast. Our empirical results strongly support our hypotheses with respect to the forecast coefficients.  相似文献

The primary purpose of this research was to investigate the effect of investment in information technology in a supply chain. The results of that investigation are presented by focusing on an empirically tested supply chain relationship model containing both behavioral and operational constructs. The four behavioral constructs represented in the model are relationship trust, relationship commitment, relationship dependence, and long‐term relationship orientation. The four operational constructs represented in the model are retailer investment in interorganizational information technology, perceived supplier investment in interorganizational information technology, logistics efficiency, and logistics effectiveness. Among other findings, the results of the investigation found that perceived supplier investment in interorganizational information technology has a significant and positive effect on logistics efficiency.  相似文献

This study investigated the extent to which style of information processing relates to media perceptions and information exposure. The results showed that visually oriented individuals were more favourably predisposed to the television medium and reported greater exposure to this medium than verbally oriented individuals. Verbally oriented individuals reported greater exposure to print media information than did visually oriented individuals. An exploratory interaction hypothesis between information processing style and gender was not supported. The implications of these results and future research directions are discussed.  相似文献

基于2010-2016年中国A股高水敏感行业的322家上市公司数据,实证检验水信息披露对股价同步性的影响,以及机构投资者的调节效应。研究表明:水信息披露对股价同步性的影响呈倒U型,且在民营企业样本中尤其显著。在国有企业样本中,机构投资者的加入能促使水信息披露更好地融入股价;在民营企业样本中,只有在高水信息披露水平下,机构投资者才能更好地发挥调节作用。  相似文献

本文研究上市公司内部人减持、年报、诉讼、分析师评级、停复牌以及高送转等重大公告前后卖空交易行为的变化,系统考察卖空者是否参与内幕交易以及何种因素影响卖空者参与内幕交易,发现卖空率较高的股票具有较低的未来收益,表明卖空者拥有信息优势,属知情交易者;卖空者拥有非常精确的择时交易能力,在重大利空公告前显著增加卖空量,而在利好公告前则显著减少卖空头寸,表明卖空者作为知情交易者的信息优势源自内幕消息;公司内、外部投资者的信息不对称程度越低或公司所在地的法治水平越高,卖空者参与内幕交易的行为就越少。因此,监管机构应密切关注公司重大消息发布前后卖空量的异常变动,同时,完善信息披露规则、健全证券分析师制度并强化法律法规的执行力度,才能有效防范卖空者参与内幕交易。  相似文献

“信息信义义务”理论已掀起网络平台监管争论的汹涌波涛,该理论经由杰克·巴尔金(Jack Balkin)教授发展,旨在“一碗水端平”一般用户与搜集、分析、出卖个人信息为业的数据公司之间的关系。在处理医患关系、律师与客户、会计师与客户的关系时,法律课以医生、律师和会计师特殊的注意、保密和忠实义务。巴尔金教授主张,与之相类似,在处理脸书(Facebook)、谷歌(Google)和推特(Twitter)等公司与终端用户的关系时,也应课以公司类似的特殊义务。过去数年里,该论断赢得了广泛的支持,鲜有敌手。但信息信义义务理论存在潜在矛盾和模棱两可之处,其是否有能力解决上述问题使人生疑。故此,本文揭示上述理论缺陷,意在瓦解“信息信义义务”新理论共识。尽管我们同意巴尔金教授“占主导地位的网络平台造成损害,由此呼唤法律的介入管制”的论断,但我们质疑信息信义义务这套理论是否能充分、恰当地回应所谓的信息不安全问题,更勿论一些更为根本的问题——建立于监视渗透基础上的优势市场份额以及与商业模式相关的根本问题。我们也呼吁重视信息信义义务这一理论框架的潜在成本——我们担心,该理论框架会对网络平台的结构性权利产生一种盲目的自满,也过早地放弃了对公共监管的更美愿景。  相似文献
