作者：
Highlights：
• In choosing research topics, researchers are found to be largeness-tracing.
• Chinese scholars trace large topics more severely than scholars from the USA, Germany and Japan.
• Papers in top journals are relatively less largeness-tracing.
• There is a positive correlation between the degree of largeness tracing and the features of papers.
