Taiwan's telecommunication firms are faced with an important challenge arising from a situation in which the growth rate of telephone subscribers has gradually decreased owing to limited market size and the policy of continuous deregulation propagated by the government. To deal with the challenge, several acquisitions among telecommunication firms have taken place and have caused the three currently leading firms to capture a market share of more than 80%. Considering how acquisitions and related strategies might affect the firms, this paper uses data envelopment analysis (DEA) under constant and variable returns-to-scale to measure firms’ efficiencies over the period 2001–2005. Because there are only three firms, DEA window analysis is employed to increase the number of decision-making units so that discriminating power can be increased. According to the results, the first finding shows that the acquisitions are justified by exhibiting higher scale efficiency (but lower pure technical efficiency) in the short run. The second finding indicates that adjusting the strategies such as enlarging market share to improving financial portfolios helps firms to achieve better scale size. The third finding justifies government efforts to privatize state-owned enterprises and liberalize the market to strengthen competitiveness.  相似文献

This study uses a two-stage approach to explore the relationship between the operational performance of U.S. telecommunications companies and their implementation of corporate social responsibility (CSR). In the first stage, this study adopts the dynamic data envelopment analysis model to measure the efficiency of the telecommunications industry in the U.S. from 2004 to 2008. The empirical results show that the corporate efficiency of those companies that implemented CSR was higher than that of those companies that did not. In the second stage, the study adopts OLS and 2SLS to explore the influence of the execution level of CSR on performance. The results show that the Kinder, Lyndenberg, and Domini & Co (KLD) social ratings indexes are significantly and positively related to corporate performance. Finally, this study suggests ways in which corporate policy makers can enhance CSR in order to improve corporate performance in the U.S. telecommunications industry.  相似文献

While withstanding a highly competitive environment, an increasing number of firms have recognized that intangible assets rather than tangible ones are vital to achieving competitive advantages. Intellectual capital has replaced physical capital as the primary basis of value creation. Although the importance of intellectual capital in ensuring superior competitive advantages is well accepted, exactly how these two constructs are related has seldom been investigated, particularly for the high-technology industry. Taking a sample of 39 Taiwanese IC design companies, this study adopted data envelopment analysis and the Malmquist productivity index to evaluate the impact of intellectual capital on competitive advantage. The analytical results revealed that approximately one third of the companies sampled had excellent efficiency in intellectual capital management, while the others still had considerable room to improve their intellectual capital management. The results of this study provide a valuable reference for future studies in alternative contexts.  相似文献

为了解上市科技型中小企业的融资现状,运用数据包络分析方法,以深圳创业板2009年至2012年初次发行股票的38家上市科技型中小企业为研究对象,对其融资效率进行综合评价,评价结果为只有15.79%的上市科技型中小企业融资综合有效,55.26%的企业既未实现技术有效,也未实现规模有效。与以往研究结果相比,中国上市科技型中小企业的融资效率有所提升,但总体效率仍然偏低。从政府和科技型中小企业自身角度出发,针对性地给出了科技型中小企业提高融资效率的意见和建议。  相似文献

Many managers, economists, and policy-makers have long believed that the production of a private enterprise is more efficient than that of a public one. This paper investigated whether it was good policy to privatize Taiwan's telecommunications industry by comparing the changes in efficiency in Chunghwa Telecom Company (CHT Co.) before and after privatization. The data envelopment analysis (DEA) model was used to evaluate their operational performance both pre- and post-privatization. The technical efficiency (CRS) computed with the CCR model assuming constant returns to scale, the technical efficiency (VRS), and the scale efficiency (VRS) were obtained with the BCC model assuming variable returns to scale, using the time-series data from CHT. The findings of this study show that the production efficiencies of CHT, both pre- and post-privatization are inefficient since all of the technical efficiencies are smaller than one.  相似文献

首先通过数据包络分析方法测算了我国30个省市区的电子信息制造业技术效率,在此基础上,在考虑了人力资本、产业集聚度、对外开放度、经济发展水平以及资本投入5个因素后,利用面板Tobit回归分别构建了全国、东部、中部及西部电子信息制造业效率影响因素模型。模型结果发现这5个因素对于各区域效率有着不同的影响,产业集聚度对东部、中部及西部区域的效率有着十分显著的正影响,经济发展水平仅仅对于西部区域的效率有着十分显著的积极影响。而人力资本对于东部、中部及西部的效率有着显著的负影响。对外开放度对东部区域效率没有显著的影响,与中部及西部区域效率之间呈现相反的相关关系。  相似文献

The literature concerned with the relationship between performance and information and communications technology (ICT) is usually focused on the ICT investments. This paper shows that it is the level of use of ICT within organisations, with preference as regards the expenses of ICT, which is responsible for the effect on performance. A general sample of 2255 Spanish companies has been used. Firms’ performance is measured as technical efficiency, which is determined by a data envelopment analysis (DEA), in which special attention is paid to the problem of the outliers. Finally, the analysis of the level of use of ICT is focused on a key area of the organisations, the supply chain, which affects the technical efficiency of the firms analysed. Results show that there is evidence of a positive effect of the use of ICT on technical efficiency. This effect is especially notable at intensive use levels in activities related to operations/manufacturing, purchasing or sales.  相似文献

New technologies are having a widespread impact on new product development (NPD)projects. In the telecommunication industry, companies are forced to integrate 'old' and 'new' ways of working with the utilization of unknown technologies. There is an emerging need to develop sustainable work systems. This paper investigates the complex relationship between NPD and the sustainability of the work systems in which it is organized. A proposed framework for analysis is followed by an examination of a specific NPD project at Ericsson.  相似文献

Supply chain risk, simulation, and vendor selection   总被引:2,自引:0,他引:2  
This paper considers three types of risk evaluation models within supply chains: chance constrained programming (CCP), data envelopment analysis (DEA), and multi-objective programming (MOP) models. Various risks are modeled in the form of probability and simulation of specific probability distribution in risk-embedded attributes is conducted in these three types of risk evaluation models. We model a supply chain consisting of three levels and use simulated data with representative distributions. Results from three models as well as simulation models are compared and analysis is conducted. The results show that the proposed approach allows decision makers to perform trade-off analysis among expected costs, quality acceptance levels, and on-time delivery distributions. It also provides alternative tools to evaluate and improve supplier selection decisions in an uncertain supply chain environment.  相似文献
