Understanding the correlation between the crystal cycle and the business cycle is important, because it can help managers to anticipate change, reduce environmental uncertainty, and formulate operational objectives. To this end, we focused on China and the U.S. in our analysis. We found that the economic indicators that were the most relevant in the characterization of China's huge and burgeoning TFT-LCD market are gross domestic production and industrial production. We complemented this finding by conducting similar analyses in the U.S. market using a more comprehensive list of economic indicators. 相似文献

The objective of this research work is to study the progress of research on technological uncertainties, social uncertainties and emerging markets and outline and identify the key disciplines, journals, articles and authors. For this the author studied the existing literature from the various fields in which technological uncertainties, social uncertainties and emerging markets research work have been published using ISI Web of Knowledge database. The paper finds that there is increasing research work on technological uncertainties, social uncertainties and emerging markets and the bibliographical search resulted in ninety-one documents written by one-hundred-sixty-one authors in eighty-four journals in seventy-two disciplines. The five major disciplines and their underlying journals are business and economics, agriculture, psychology, public administration, and environmental sciences and ecology accounting for majority of publications. In journals the most prolific, measured by number of articles published are Harvard Business Review, Social Science and Medicine, World Development, and Higher Education; and most influential, measured by the global citation received, are Harvard Business Review, Social Science and Medicine and Sociological Review. The top 10% of the journals are responsible for 23% of all publications but 85% of all global citations received. This highlights that despite the high, diverse and increasing number of journals; only few are dominating and shaping the research arena of technological uncertainties, social uncertainties and emerging markets. Further, in the ten most cited articles, no author appears more than once. 相似文献

Forecasting of electricity costs based on an enhanced gray-based learning model: A case study of renewable energy in Taiwan 总被引:1,自引:0,他引:1

This work presents a novel gray-based cost efficiency (GCE) model that integrates the gray forecasting model into a two-factor cost efficiency curve model for renewable energy (RE) technologies and identifies the optimal forecasting model for power generation cost of RE technologies. The analytical framework of proposed GCE model improves short-term prediction of power generation cost, and can be applied during the early developmental stages for RE technologies. Empirical analysis is based on wind power data for Taiwan. Time lag of knowledge stock was simulated to represent the actual relationship between R&D expenditures and cost reductions in power generation by knowledge stock. Analytical results demonstrate the GCE model is a useful tool to quantify the influences of cost reductions in power generation. The implications of analytical results are that institutional policy instruments play an important role in RE technologies achieving cost reductions and market adoption. The proposed GCE model can be applied to all high-technology cases, and particularly to RE technologies. The study concludes by outlining the limitations of the proposed GCE model and directions for further research. 相似文献

Because enterprises do not disclose their internal specific cost information to the public and, moreover, every firm has its own product character and financial constitutions, it is difficult to offer fixed guidelines for investment decisions. Thus, an enterprise may be uncertain when required to choose the most promising set of possible investments.The goal of this research is to use a grey relation analysis and analytic hierarchy process (AHP) to probe the core product development and competitiveness of an enterprise from limited data and, furthermore, by constructing the grey model, GM(1,1), to validate the feasibility of this assessment of the core competitiveness and investment strategy. In this study, a precision mechanical manufacturer is taken as an example, and the forecast estimate from this method is compared to those of a linear regression and the actual values to demonstrate the feasibility of applying this methodology to investment decision making, hence, demonstrating the value of this research. 相似文献

Times of crisis bring about increased demands on businesses as shortages, or unexpected but significant, business costs are
encountered. Passing on such costs to consumers is a challenge. When faced with a retail price increase, consumers may rely
on cues as to the motive behind the increase. Such cues can raise suspicion of alternative motive (e.g., taking advantage
of the consumer) affecting consumers’ judgments of price fairness. This research investigates two triggers of suspicion: salience
of alternative motives, and behavior judged to be out-of-character for the business. Results of the two studies within crisis
contexts indicate that suspicion is created when alternative motives are salient and when a retailer acts out-of-character.
Multiple group analyses revealed that suspicion induced negative affect and subsequent perceptions of price fairness. When
suspicion was present, more negative feelings toward the retailer and judgments of price unfairness resulted. 相似文献

This analysis employed a highly disaggregated household data set of Alberta and Ontario fast food purchases from May 2000 to May 2005. A double-hurdle count data model allowed tests of the hypotheses that frequency of Bovine spongiform encephalopathy ( BSE) media coverage affected neither a household's monthly probability of purchasing a beef entree, nor the household's monthly quantity of beef entrees purchased. Ontario consumers were more likely to stop purchasing beef entrees immediately following a surge in BSE media coverage, but those who did buy beef entrees maintained stable quantity levels. BSE media coverage did not systematically affect fast food purchases among Alberta consumers .
Dans la présente analyse, nous avons utilisé un ensemble de données fortement désagrégées sur les achats de repas–minute effectués par des ménages de l'Alberta et de l'Ontario, entre mai 2000 et mai 2005. Un modèle de comptage à deux étapes (double hurdle count data model) a permis de vérifier les hypothèses selon lesquelles la concentration de la couverture médiatique de la crise de l'ESB n'influence pas la probabilité mensuelle d'un ménage d'acheter des repas–minute de bœuf ni la quantité mensuelle de repas–minute de bœuf achetés par un ménage. Les consommateurs ontariens étaient plus susceptibles de cesser d'acheter des repas–minute de bœuf immédiatement après une poussée de la couverture médiatique de la crise de l'ESB, mais ceux qui achetaient des repas–minute de bœuf ont maintenu les quantités achetées. La couverture médiatique de la crise de l'ESB n'a pas systématiquement influencé les achats de repas–minute chez les consommateurs albertains . 相似文献

This article analyzes how sociodemographic characteristics impact the adoption of online grocery shopping, and relies on the Motivation-Opportunity-Ability (MOA) model to explore what these sociodemographics actually capture and how they are linked with consumer motivations. The researchers exploit a survey among 468 customers of Belgian supermarket chain Colruyt. Their logistic regression shows that while variables at the personal level do affect adoption of the online channel, consumers’ motivations to adopt in fact lie on the household level. In particular, the effect of age disappears or becomes less strong when it is combined with household characteristics. An examination of respondents’ self-reported motivations confirms that age does not only capture a person’s ability to use the technology but also its usefulness for that person’s household, in that age is correlated with the presence of young children and the working situation in the household. 相似文献

The contribution of vacations to people’s life satisfaction and Quality of Life (QOL) has recently attracted substantial attention among tourism researchers. Yet, most QOL scales do not include vacations: 7% explicitly measure vacations whereas 42% only include items relating to vacations within the broader Leisure domain. Leisure and vacations, however, differ substantially in nature with leisure referring to regular home-based activities and vacations being infrequent leisure activities away from home. As a consequence of the common amalgamation of vacations with leisure, there is limited knowledge about the specific contribution of vacations to people’s QOL. The present study (1) presents empirical evidence for the contribution of vacations to QOL, (2) determines the extent of this contribution, and (3) investigates variation in the extent to which vacations contribute to the QOL of different people. Results indicate that vacations contribute to the QOL of the majority of people, are as important a QOL domain as Leisure and People, and that QOL means different things to different people at different points in their life, representing an individual and dynamic concept. 相似文献

This study attempts to explain the influence of personal and hotel factors on the expectation level of hotel hospitality as well as to propose a scale to measure commercial hospitality for hotel services. A total of 101 local and international hotel guests were involved in the study. The results revealed that the expectations of hotel hospitality are influenced by personal factors such as gender, purpose of stay, nationality, and private domain of hospitality. The hotel's star rating is the only hotel factor that might have strong association with hotel hospitality. 相似文献
