This paper uses a set of unique data from Chinese listed companies to examine the influence of analyst coverage on corporate philanthropy. Results show that companies followed by more analysts engage in more philanthropy, which provides support for the reputational capital view of corporate...

The mathematical model is often used for fitting the trend of changes in cultivated land resources in the land use planning, but the fitting effect is different in different study areas. In this paper, we take two geographically adjacent cities with great differences in the economic development...

Since high temperature superconducting magnetic energy storage system (HT SMES) has attracted significant attention for their fast response in milliseconds, high efficiency (cyclic efficiency over 95%) and unlimited times of charging and discharging cycles, it can be used for system stabilizing...

The demand for petroleum has risen rapidly due to increasing industrialization and modernization of the world. The limited reserve of the fossil fuels is also dwindling alongside escalation in the prices. The threats from these and food insecurity are, however, drawing the attention of...

We investigate the nature of sovereign credit risk for selected Asian and European countries based on a set of sovereign CDS data over an eight-year period that includes the episode of the 2008-2009 global financial crisis. The principal component analysis results indicate that there exists...

Using a sample of 324 acquisition deals originated by nonstate-owned enterprise (SOE)-listed companies to acquire nonSOE private firms in China, we find that politically connected firms are more successful at acquiring high-quality local businesses than firms without political connections. The...
