ABSTRACT

The aviation e-service system is an important part of support for business communication in regions covered by Belt and Road initiative. In exploring the role of airline companies in this system, we examine the structure of the network, which consists of airlines interconnections based on small data of individual attributes of aviation companies in aviation e-services, and study these interconnections across different groups using block modeling. The heuristic solution of airline companies in development of international communication and cooperation is further discussed. Among our policy implications for global managers, we suggest the enhancement of cross-regional cooperation among airlines.  相似文献

The use of fundraising strategies in professional associations is on the rise as member donations have become an increasingly important revenue stream for the associations. This study aims to understand why member volunteers are potential donors to professional associations and to examine whether association solicitation is effective in increasing member volunteer donations. A moderated mediation model was tested with data that consisted of 3,224 professional association members. The results suggest that member satisfaction significantly mediates the relationship between member volunteering and financial giving, and solicitation only makes a difference to member volunteers who are satisfied with their membership. This study concludes that targeting satisfied member volunteers for donations could yield financial benefits to professional associations.  相似文献

This paper investigates the price adjustment and lead-lag relations between returns on five size-based portfolios in the Taiwan stock market. It finds evidence that the price adjustment of small-stock portfolios is not slower than that of large-stock portfolios. Additionally, limited evidence supports a positive leading role of large-stock portfolio returns over small-stock portfolio returns. These two findings are substantially different from the results of previous research on developed markets.  相似文献

The development of the semiconductor industry depends on its interactions with the environment. Developing countries face more constraints and the environmental interactions seem more complicated. The development process of the semiconductor industry could be better understood with regard to the interactions and social changes. This study proposes a variety-increasing viewpoint based on the concepts of variety increasing and internal learning to analyze the developmental experience of the semiconductor industry in Taiwan. The result shows that the development of Taiwanese semiconductor industry is a continuous variety-increasing process, which is achieved by searching and establishing successful associations in an increasingly wider and complex environment. Implications on the ongoing development of Taiwan's semiconductor industry and the development experiences of other East Asian countries are discussed.  相似文献

abstract    Studies on the three types of process improvement programmes (Continuous Improvement, Reengineering and Benchmarking) have appeared many times in the literature. These studies suggest that certain organizational variables act as enablers and their presence or absence can significantly influence success rates. Such studies have tended to examine companies where a single programme has been implemented. In contrast, this paper examines a sample of companies who have experienced all three programmes. Our aim is to compare and contrast each programme's impact on firm performance and identify which organizational variables are common and which are programme-specific enablers of success. We build and test an integrative framework to support our analysis. Our study found that: (1) Reengineering delivered the greatest impact on performance; (2) executive commitment was needed to make this happen; (3) strategic alignment was the major influence on the success rate of Reengineering and Continuous Improvement programmes; and (4) employee empowerment was necessary for each programme to work effectively.  相似文献
