针对射频信号自动识别(RFID)技术发展受多种因素影响,变化趋势复杂,难以通过建立准确的数学模型进行预测的问题,本文提出了灰色动态模型对射频信号自动识别(RFID)技术发展趋势进行预测,在此基础上构造了灰色神经网络组合预测模型。该模型避免了变权组合预测模型的主观与繁琐,能有效地将灰色预测弱化数据序列波动性的优点和神经网络较强的非线性适应能力相融合。算例结果表明该方法的可行性和有效性,预测精度也得到了改善。 相似文献

Some tourists only have a slight idea of where they want to go on a holiday when planning starts. Such tourists or their travel partners are likely to look for information for making a final travel decision. As the web becomes an increasingly popular information source, tourism destination websites can play a critical role in destination choice. A rubric for comparing tourism websites put forward by Dion and Woodside (2010) is used and ideas for enhancing the rubric are introduced utilizing a growing literature. Comparisons are made for the tourism websites of Hong Kong, Shanghai, Beijing, and Taipei. Analysis involves considering websites' quality and usefulness. The study indicates that Hong Kong's site is best while Beijing has the most room for improvement. The paper concludes with implications of the research for website analysis. The discussion includes contributions to the value of criteria for websites found in the literature but not covered in an information-quality performance rubric. 相似文献

随着深圳物流业的崛起,深圳与香港物流业竞争力的比较越来越受到业界的关注。通过在生产要素成本、组织成本和要素质量三个方面对深圳和香港物流业的竞争力的实证分析,表明深圳的要素成本比香港有明显的优势,但是深圳的制度成本比香港要高。在生产要素质量方面,深圳与香港的“硬要素”差距不大,“软要素”差距比较大。深圳中低端物流业务的竞争力正在接近甚至超越香港,将促使原本在香港境内的此类业务向深圳、珠江三角洲等地区转移。 相似文献

By building on insights from institutional isomorphism, this paper investigates the development paths of latecomer business schools in Hong Kong, (South) Korea, Singapore, and Taiwan. The global isomorphic pressure prevalent in higher education (e.g. the global regime of rankings) drives latecomers to imitate the practices of incumbents in order to enhance their academic impact through business and management research. Our study argues that latecomers respond to global isomorphism by forging their own paths. Our analysis shows that business knowledge production in Hong Kong and Singapore was more responsive to coercive (research strategy) and normative (faculty recruitment strategy) isomorphic pressure than Korea and Taiwan. The response to mimetic isomorphic pressure (co-authorship strategy) was less salient in Hong Kong and Taiwan than in Singapore and Korea. Further, we find that research, faculty recruitment, and co-authorship strategies affect the academic impact (citations) of the higher education institutions across each country differently. Our study sheds new light on the role of global isomorphism in the emergence of latecomer business schools. 相似文献

Abstract Since the opening of China in 1980, Hong Kong manufacturing industries collaborated with China manufacturing industries to maintain a low-cost labor intensive strategy. The strategy seems to be sufficient in maintaining the global competitive advantage of Hong Kong for the past two decades. However, with the rapid organizational learning of the Chinese partner and the reluctance of the Hong Kong partner to upgrade technology, Hong Kong manufacturing industries are facing the risk of potential loss of competitive advantages. This article attempts to review this dynamic evolution of HK/China collaborations and suggest some future actions for Hong Kong manufacturing industries to maintain their competitiveness. At the same time, the article also provides some ideas for global investors to rethink their future firm strategies in China. 相似文献

Hong Kong's tourism industry collapsed around July 1997, shortly after the hand over to Chinese rule. When the Asian financial crisis hit, Hong Kong's investments in neighboring countries suffered. Thereafter the Heng Seng Index dropped 55 percent. Throughout the last quarter of 1997 Hong Kong's economic inhibitors—unemployment, business failures, and negative GDP—all pointed to a recession. Among Hong Kong's hotels, more than 1,750 jobs were lost from December 1997 to March 1998, and average room rates dropped below 1991 levels. Hong Kong's tourism crisis can be traced to: an imbalance between room supply and demand (caused by the inflated demand for office space), unfair hotel pricing to take advantage of Japanese tourists, ineffective national promotional campaigns, airline woes, and food-borne illnesses that scared away visitors. Economic recovery is likely to take several years, and is dependent on the recovery of the rest of the region's countries. In June 1998 Hong Kong produced an economic-stimulus package to stem the tide of decreasing land values and stimulate the money supply. Hoteliers can help by working together to ensure pricing stability. Coordination is also needed between the Hong Kong Tourist Association and the rest of the industry to set goals and objectives. Hospitality education and training need to focus on the current needs of the industry and on how to compete in the new market. 相似文献

Small Firm Marketing in China: A Comparative Study 总被引:2,自引:0,他引:2
This paper examines the influence of Chinese cultural values on marketing practices in different socio-cultural settings and business contexts, for example the United Kingdom, Hong Kong and China. 20 Chinese small firms in China were selected and their owner-managers were interviewed. Findings of interviews undertaken by Brooksbank et al. (1992) with 20 British small firm chief marketing executives, and Siu (1997) with 26 Chinese owner-managers in Hong Kong, were collated to form a database for comparison purposes. The research results suggest that the specific marketing practices of Chinese small firms in mainland China are different from those of their counterparts, for example, British and Hong Kong Chinese small firms. A tentative model is developed explaining the factors that appear likely, on the basis of this research, to affect the marketing performance of small firms in China. 相似文献

In this contribution, the future market of business and management education in Hong Kong is investigated, bearing in mind that Hong Kong reverted to Chinese sovereignty. Hong Kong is expected to continue its prosperity, but the emigration of large numbers of Hong Kong professionals wanting to secure a safety net by acquiring a foreign passport has further created demands for better and more business and management education in an attempt to develop more professional managers. The study starts by discussing the current state of the Hong Kong economy and the phenomenon of the ‘brain drain’. In addition, it analyses a survey of the current state of business and management education in Hong Kong so that a market need can be identified to match economic growth. Finally, the study suggests a future research direction for Hong Kong's business and management education. 相似文献

Out of the Mouths of Babes: Business Ethics and Youths in Asia 总被引:1,自引:1,他引:0
A model of corporate ethics and social responsibility (CESR) was developed and empirically tested among Chinese business undergraduates in Hong Kong and Singapore. As predicted, it was found that CESR beliefs were negatively related to Machiavellianism and two Confucian concepts, guanxi (interpersonal connections) and mianzi (face). CESR beliefs were also lower among Hong Kong than Singaporean youths. The negative effects of guanxi, mianzi, and Machiavellianism were more pronounced for the Hong Kong than Singapore sample. Implications of these findings are discussed and directions for future research suggested. 相似文献

This study examines how restaurant customers make trade-offs among several restaurant rate fences using a sample of mainland Chinese travelers to Hong Kong. A total of six restaurant rate fences (i.e., lunch/dinner pricing, weekday/weekend pricing, table location pricing, restricted coupon pricing, meal period, and reservation and seating policy) and menu price were selected, and a conjoint analysis was performed. Findings reveal that price, restricted coupon pricing, and meal period are the most important attributes when restaurant customers select a restaurant. This study is the first attempt to examine the relative importance of different types of restaurant rate fences. The findings will help restaurant operators to better understand the decision-making process of Chinese travelers and design appropriate rate fences accordingly. 相似文献
