This paper investigates the relationship between linguistic logical coherence ability and English writing level. By analyzing the English writing samples of 120 students, it was found that the high level students had a significantly more heightened awareness of the importance of writing, writing ideas and skills than the middle and low level students, with a mean score of 3.5. Regarding logical coherence, the means of the three level groups were 398.456, 388.874, and 369.596 respectively, showing that the high level group performed better. It was further found through multiple linear regression analysis that logical coherence skill significantly affects English writing. Specifically, logical connectivity, identification, and matching skills contribute the most to improving English writing. The study results suggest that training linguistic analytical coherence skills, especially in logical connection and identification, is essential for improving students’ English writing level.
