In order to understand the scientific research ability of clinical teachers guiding nursing undergraduates in teaching hospitals, 221 clinical nursing teachers in 3 grade Ⅲ hospitals were investigated. The questionnaires included general information, research participation, paper writing and nursing research knowledge. The results show that the scientific research awareness of teachers in these hospitals is deficient. 51.1% of them participated in scientific research, 6.8% took charge of projects, and 51.6% published papers. Teachers with better educational background took part in more research projects and published more papers than the others, and the difference is significant (P<0.01). Those with higher professional titles or from affiliated hospitals published more papers than those with lower titles or from non-affiliated hospitals, and the difference is significant (P<0.01); however, there is no significant difference in research participation between them.
