The invention discloses an intestinal metagenome feature as a type-2 diabetes acarbose curative effect selection marker. The intestinal microorganism metagenome feature is the bacteroides intestinal pattern. By using the intestinal pattern concept for the first time, it is found that type-2 diabetes patients with different intestinal parasitic bacterium groups make remarkably different treatment responses to diabetes hypoglycemic drugs acarbose, and therefore before the drugs are used, the intestinal patterns of the patients can be distinguished, people with the optimal curative effect are selected, and whether acarbose is suitable for conducting diabetes treatment on the individual type-2 diabetes patient or not is judged.
