This study evaluates tourism experiences shared through electronic word-of-mouth (eWOM) across four Chinese attractions. The objective is to develop a framework for evaluating eWOM by constructing an indicator system and implementing an analytic hierarchy process with the use of a fuzzy comprehensive evaluation algorithm. This framework is achieved by mapping more than 6000 websites related to Chinese tourism attractions and filtering over 200,000 useful reviews to measure service performance. Results indicate that ecological–biological attractions failed to make tourists feel “very satisfied” in various aspects, such as overall evaluation, infrastructure, traffic, natural environment, and social environment. Overall, the study contributes by presenting a framework that can be adopted by tourism researchers and industry practitioners to understand tourist preferences and evaluate service performance to improve service quality. 相似文献

经理人员对上市公司的内部控制已不能完全解释上市公司的财务报告舞弊问题,大股东控制了上市公司,通过对上市公司的利益侵占获取私人收益,财务报告舞弊是隐瞒大股东行为的手段。本文以截至到2005年受到证监会处罚的上市公司为样本,分析了股权结构与财务报告舞弊的相关性,从股权制衡与培育大股东诚信义务方面提出了治理大股东行为的建议。 相似文献

Predictive analytics is impacting many diverse areas, ranging from baseball and epidemiology to forecasting and customer relationship management. Manufacturers, retailers, software companies, and consultants are creatively discovering new applications of big data using predictive analytics in supply chain management and logistics. In practice, predictive analytics is generally atheoretical; however, we develop a 2 × 2 model to explain the role of predictive analytics in the theory development process. This 2 × 2 model shows that in our discipline we have traditionally taken one path to theory development, but that predictive analytics can be a salient component of a comprehensive theory development process. The model points to a number of research questions that need to be addressed by our research community. These questions are not just highly relevant to the academic community but also in urgent need of answers to help practitioners execute the right strategies with greater precision and efficiency. We also discuss how one disruptive trend, the maker movement, changes the nature of who the producers are in the supply chain, making big data even more valuable. As we engage in higher levels of dialogue we will be able to make meaningful progress addressing these vital research topics. 相似文献

After Lehman Brothers bankruptcy in 2008, the Central Bank of China (PBOC) created a big 1.8 trillion dollars package to boost the Chinese economy. It was a necessary key measure not only to prop up the economy, but also to try to preserve the two-digit growth of the GDP that existed before the Great Recession. The financial instability of international financial circuits made necessary the involvement of the central bank. Ten years later, China’s debt explosion went up during the financial crisis, from six to twenty-eight trillion dollars between 2007 and 2016. In other words, it went up from 148 to 260 percent of GDP during the same period. The goal of this article is to analyze whether China is living a “Minsky moment” or not, and what its implications are for international financial markets. 相似文献

We investigate the claim made by proponents of the big‐bang strategy that the establishment of property rights in an economy in transition creates its own demand for the enforcement of laws to protect those rights. Our model contains a government engaging in activities to accomplish objectives that depend on public support for the enforcement of the rule of law and agents who interpret the level of activities of the government as indications of the government's intent to enforce the rule of law. Agents, using the level of government activities as an input to their decisions, choose whether to support the government's objectives. We establish conditions under which the level of activities chosen by the government maximizes its benefits, and simultaneously induces the constituency to support enforcement of the rule of law. These conditions provide a basis for the argument for the implementation of the big‐bang policy. When these conditions do not hold, however, we show that the level of activities that maximizes the government's benefits may have only a minor impact on support for the enforcement of the rule of law. Two characteristics play an important role in these conditions: the initial level of crime and the types of activities the government chooses to undertake. We present examples showing that the initial level of crime has the more dramatic effect on subsequent support for the rule of law. 相似文献
