ABSTRACTThe 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

在建筑工程的施工过程中,由于现场环境过于复杂,劳动过于密集,很容易发生各种类型的安全事故。建筑工程施工中经常涉及高空作业,所以高空坠落事故的发生几率相对较高。要想保证建筑工程行业的健康发展,就必须加强安全管理,降低高处坠落事故的发生几率。论文重点针对建筑工程高处坠落事故的发生原因进行了详细的分析,并针对性地提出了预防措施,以供参考。 相似文献

近年来,控股股东股权质押风险成为资本市场面临的一个突出问题.在债券市场的信用风险日益受到重视的背景下,研究控股股东股权质押风险如何影响债券投资者行为显得尤为重要.本文基于我国2007~2018年公司债券和控股股东股权质押数据,采用断点回归的方法研究了控股股东股权质押对公司债券信用利差的影响.结果发现,公司股价触及控股股东股权质押警戒线后,公司债券的信用利差跳跃式上升;上述信用利差的"跳跃"仅存在于安全性较高的债券中.进一步研究发现,在跌破警戒线后的平仓线附近,信用利差不再跳跃式上升;良好的信息环境并不会抑制信用利差的跳跃式上升.这些结果排除了信息传递假说和隐瞒信息假说,支持了局部思维假说.本文揭示了控股股东股权质押对债券信用利差的作用机理,对于抑制股票市场向债券市场传导风险具有重要价值. 相似文献

Initial public offerings (IPOs) are typically offered at prices lower than the transaction price in the early aftermarket. With a stochastic frontier model, we measured the fair offer price of an IPO and then the deliberate IPO underpricing and the market misvaluation based on the estimated fair offer price. Our results show that IPOs are deliberately underpriced. The extent of noisy trading leading to significantly higher market transaction prices explains the excess IPO returns. We conclude that initial IPO returns result primarily from the noisy trading activities instead of the deliberate IPO underpricing. 相似文献

This article evaluates vulnerable American options based on the two-point Geske and Johnson method. In accordance with the
Martingale approach, we provide analytical pricing formulas for European and multi-exercisable options under risk-neutral
measures. Employing Richardson’s extrapolation gets the values of vulnerable American options. To demonstrate the accuracy
of our proposed method, we use numerical examples to compare the values of vulnerable American options from our proposed method
with the benchmark values from the least-square Monte Carlo simulation method. We also perform sensitivity analyses for vulnerable
American options and show how the prices of vulnerable American options vary with the correlation between the underlying assets
and the option writer’s assets.
