2021年,随着煤炭市场价格的不断高企,大用户直供交易和竞价上网等规模的不断扩大,发电企业的盈利能力水平遭受大幅度的削弱,火电行业整体处于亏损的经营局面,发电企业的生存环境极度恶化。如何在不断变化的市场环境中生存下来,是发电企业不得不面临的一个重要问题,本文以Z发电企业为例,通过对Z发电企业的资金管理现状进行剖析,制定出行之有效的具体措施,以期进一步提升发电企业的资金管理能力和创效水平。 相似文献

We build a simple overlapping generation model to investigate the effect of life expectancy on the real exchange rate where fertility is chosen endogenously. The model reveals that, although the overall effect of life expectancy on the real exchange rate is not certain, longer life expectancy tends to cause the real exchange rate to depreciate by reducing fertility. Fertility thus serves as a mediator in the effect of life expectancy on the real exchange rate. Evidence from 148 economies (1980–2018) shows a statistically significant and robust negative relationship between life expectancy and the real exchange rate. It is estimated that a 1 year increase in life expectancy is associated with a 1.5 percent depreciation in the real exchange rate. The evidence also confirms the mediated effect of fertility. The mediated effect that fertility exerts accounts for 30 percent to 50 percent of the total effect, depending on the real exchange rate index used. 相似文献

We are at a turning point in the debate on the ethics of Artificial Intelligence (AI) because we are witnessing the rise of general-purpose AI text agents such as GPT-3 that can generate large-scale highly refined content that appears to have been written by a human. Yet, a discussion on the ethical issues related to the blurring of the roles between humans and machines in the production of content in the business arena is lacking. In this conceptual paper, drawing on agenda setting theory and stakeholder theory, we challenge the current debate on the ethics of AI and aim to stimulate studies that develop research around three new challenges of AI text agents: automated mass manipulation and disinformation (i.e., fake agenda problem), massive low-quality content production (i.e., lowest denominator problem) and the creation of a growing buffer in the communication between stakeholders (i.e., the mediation problem). 相似文献
