In this paper, a holistic analytical framework for tracing and understanding the progress of e-development is developed and adopted in an empirical case study of China’s e-development since 1998. In particular, the progress is analyzed systematically by benchmarking various ICT infrastructure and e-devices, the composition of Internet users, and the key dimensions of e-government, e-working, e-commerce, and e-networking. In addition, the questions of whether the geographical digital divide in the country has been narrowed is examined. Our findings show that (1) China has made noticeable progress in the e-development since 1998; yet, progress varied in different dimensions; (2) based on the overall performance, 2004 can be considered as the watershed for China to move from the formative stage to the developmental stage; (3) during the e-development, digital disparities in China have dramatically decreased at the provincial level, however, the urban-rural digital gap widened. We suggest that other than promoting affordable ICT possession, the wider and more diversified e-applications for different walks of life will be important for China to move towards the mature stage. 相似文献

In this paper, we examine the match between resource relatedness and post-merger integration on technology innovation of acquiring firms to find the rationale behind technology-sourcing cross-border mergers and acquisitions (M&As) of Chinese multinational enterprises. Using a sample of 88 Chinese technology-sourcing cross-border M&As, we find that the acquirer will improve technology innovation when greater resource similarity between the acquirer and target firms is matched with a high integration degree and a low target autonomy level. Meanwhile, the acquirer can improve technology innovation when greater resource complementarity is matched with a low level of integration degree in technology-sourcing cross-border M&As. This paper provides the acquiring firms with fresh ideas of how to make the integration decisions of technology-sourcing overseas M&As. We hope to help multinational enterprises to achieve more outstanding technology innovation performance through technology-sourcing overseas M&As in an intense global competitive environment. 相似文献

Fundraising techniques used by charities can enhance or diminish public trust. The dangers of questionable and over-aggressive fundraising practices are very real. In particular, in the UK, the ‘Olive Cooke affair’ in 2015 triggered a highlevel examination of fairly widespread dubious practices. In this article, the reflections of a key actor on the events surrounding the affair, and subsequent fallout, are examined. It is argued that this whole saga has the potential to encourage the development of a charity sector that is more trusted by the public; a sector that has stepped back from the abyss. 相似文献

20世纪30年代以来,关于中国古代旅游研究的成果陆续出现,目前尚无有关研究的全面综述。该文分别对早期中国古代旅游研究以及中国古代旅游文学、旅游史、旅游文化、旅游地理与旅游经济研究现状做了概要梳理,并以中国知网期刊论文为数据来源进行统计分析,认为1997年以后中国古代旅游研究有所发展,现有成果的研究重点分别为中国古代以及明清、唐宋旅游,长江中下游地区旅游,旅游史、旅游文化与旅游文学。基于以上梳理与分析,研究认为中国古代旅游研究的进一步发展需要突破视域、理论、方法以及实用性评价标准的局限。 相似文献

This article aims to evaluate the service quality experienced at academic conferences held at the Universidad Técnica Particular de Loja in Ecuador. Our approach is based on fuzzy logic and ideal solutions to calculate a global attendee satisfaction index for specific market segments: Gender, nationality, and age. Current literature on the service quality experienced by conference attendees is still scarce. Our results show that the analyzed segments experience varying levels of satisfaction, and that the more influential attributes to each of them are also different. Our results can be applied to improve the competitiveness of Loja and that of Universidad Técnica Particular de Loja. 相似文献

Ethiopia has implemented one of the largest, fastest and least expensive land registration and certification reforms in Africa. While there is evidence that this ‘first-stage’ land registration has had positive effects in terms of increased investment, land productivity and land rental market activities, the government is now piloting another round of land registration and certification that involves technically advanced land survey methods and computer registration. This ‘second-stage’ land registration differs from the registration system employed in the first round that used field markings in conjunction with neighbors’ recollections to identify plot borders. We use panel data from 600 households in southern Ethiopia to investigate household perceptions of and demand for such a new registration and certification. Our study revealed relatively low demand and willingness-to-pay (WTP) for second-stage certificates. The WTP also decreases significantly from 2007 to 2012. Our findings indicate that farmers do not believe that the second-stage certificate enhances tenure security relative to the first-stage certificate except in instances in which first-stage certification was poorly implemented. The demand for second-stage certificates appears to come primarily from governmental authorities, as it can provide a better basis for land administration and produce accessible public documentation of land-related affairs. 相似文献
