Based on elaborating the positive impact of AI technology on academic writing, this paper analyzes the trend of academic ecological reform under the empowerment of AI and establishes a model for the cultivation of academic writing ability in business. Then based on Seq2Seq model, BiGRU model and Luong attention mechanism are introduced to establish the intelligent error correction model of business academic writing based on fixed-length Seq2Seq network. And based on the model of academic writing ability cultivation in business class, the teaching practice research is carried out with the students of a university as the research object. The results show that the F0.5 value of the intelligent error correction model reaches 38.81%, which is 5.18 percentage points higher than that of the sub-optimal Seq2Seq+BiGRU model, and the students’ academic writing ability under the business academic writing ability cultivation model improves by 11.68 points compared to the preexperimentation period, which is a highly significant difference (t=9.586, P=0.000< 0.01). Therefore, based on artificial intelligence technology can promote the academic writing ability of business students significantly and improve the quality of academic writing in business.
