信息通讯业的产业融合   总被引:135,自引:4,他引:135  
作者认为,20世纪90年代以来,曾一直被政府严格限制的产业现在正在逐步放宽限制,从而降低了各行业间的壁垒,加之各产业内促进行业竞争的技术在快速发展,这些因素都推进了产业融合的进程,导致了企业合并、合作的频繁发生。该文以信息通讯业的产业融合为例,分析了这方面的有关情况。  相似文献

文字是人类文明进步不可缺少的基本工具,它既是语言的载体,也是信息化社会的基础。拉丁字母文字从一万多年前的原始文字到现代表音的字母文字,经历了漫长的原始文字、古典文字和字母文字三大阶段,文字形态的每一个变化,在保有历史痕迹的同时,也实现了更加快速有效传达信息的目的。各个时代不同的文字书写工具和载体作为媒介指导了信号的传递,并直接影响到当时的文字形态和信息传达。古登堡铅活字印刷术的发明带来了信息传递的重大技术变革,使得文字形态进入印刷文化阶段;印刷油墨和纸张作为文字的新载体在世界范围内推广,陆续产生了现在依然有影响力的诸多拉丁字母文字。铅字字模印刷文字形态的一致性,使得固定形态重复出现时的文字可识别性大大提高,形成了规范的印刷品文字形态,使文字的易读性和可读性明显优于形态相对不固定的手写体,使信息能够被更加清晰准确地传递,对更好地实现文字的功能具有重要意义。随着信息化社会的发展,印刷文字扮演着越来越重要的角色,拉丁字母文字印刷体形态如何更好地传达信息必将得到更大的关注和更深入的研究。  相似文献

Design and problem-solving is a key learning focus in technology education and remains a distinguishing factor that separates it from other subject areas. This research investigated how two expert designers considered experiences with hard materials contributed to their learning design and problem-solving with these materials. The research project used a qualitative approach and conducted semi-structured interviews with two mechanical engineers. They identified their experiences under three key headings that provided them with much of the essential knowledge and understanding they employ today to design and problem-solve with hard materials. These included experience of seeing outcomes that provided feedback on their designs, experiences that informed about materials and material selection and accessing others’ experiences from communities of practice.  相似文献

This paper investigates the cointegration and causal relationships between Information and Communication Technology (ICT) and economic output in Australia using data for about five decades. The framework used in this paper is the single-sector aggregate production function, which is the first comprehensive approach of this kind to include ICT and non-ICT capital and other factors to examine long-run Granger causality. The empirical evidence points to a cointegration relationship between ICT capital and output, and implies that ICT capital Granger causes economic output and multifactor productivity, as does non-ICT capital.  相似文献

企业家寻租行为及特征分析   总被引:14,自引:0,他引:14  
作者把企业家的活动分为非生产性(即浪费性)的寻租活动(如行贿)和生产性的创造创新活动(如创新),以经济人假设作为基础,企业家不仅为企业获得垄断地位和竞争优势,同时也为自己和小集团谋求利益,企业家的活动本身具有双重性质,如果把企业家活动的生产性质作为寻租概念一个维度,相对于非生产性活动(会造成社会福利损失)而言,生产性的创新活动实际就是生产性寻租活动。  相似文献

Researchers have conducted surveys of firms in an attempt to test various theories of wage rigidity. The survey of Australian firms reported in this paper found strong support for the view that hiring and training costs are important reasons why employers do not reduce wages, consistent with the surveys of Blinder and Choi (1990), Bewley (1995, 1999) and Kaufman (1984). All the surveys find pervasive support for the notion of fairness as an explanation for wage rigidity. Qualified support was found for the idea that fear of unemployment motivates worker effort.  相似文献

This paper examines an antitrust enforcement policy of using significant price changes in an industry as a sorting mechanism for the allocation of resources devoted to policing collusion. That is, in either responding to complaints or initiating investigations on their own, I examine the issue of whether an antitrust enforcement policy of inferring possible collusion from significant prices changes is effective in deterring collusion given that antitrust officials have no direct knowledge of the costs of individual firms. Using the imperfect information repeated game of Green and Porter (1984), I show that this investigation strategy if coupled with uniform costs being borne by firms, can reduce the expected profits from the collusive agreement: however, unless the punishment is large enough, it will be ineffective in reducing the frequency of collusion. More importantly, it can have the undesirable effect of reducing the output agreed to by firms, if firms choose quantities, or raise collusive prices if firms are choosing price. Moreover, if the enforcement policy is anticipated by firms, the punishment mechanism adopted to support collusion will be altered to offset the policy.  相似文献

In recent years there has been a growing interest in the impact of co-operative union–management relations on firm performance and organizational outcomes such as employee turnover and absenteeism. This paper seeks to identify the factors that affect the development of a co-operative industrial relations climate and analyses the effects of that climate on organizational and union allegiance and on employee attendance behaviour. The data are drawn from a study of a large automotive manufacturer in Australia. The results indicate that a positive union–management relationship is associated with higher levels of work attendance. Moreover, this outcome is consistent with the presence of strong and effective unionism at the workplace.  相似文献

Industrial organization theory has identified strategic investment in capacity as an important element in competition in oligopolistic markets. In the paper we specify a model of oligopolistic investment behaviour, and test it with panel data for 114 firms in 15 narrowly defined UK manufacturing industries in the 1970s and 1980s. The industries are distinguished according to their market characteristics as fragmented, dominant firm and dominant group sectors. The results indicate behaviour which is noncooperative in fragmented sectors, cooperative in dominant group sectors and competitive in dominant firm sectors.  相似文献
