<abstract>We consider the Cauchy problem for the Schr&#246;dinger-improved Boussinesq system. We prove the local well-posedness below $L^2$ and the global one in $L^2$. The main ingredient for the local well-posedness is nearly optimal bilinear estimates related with the Schr&#246;dinger-improved Boussinesq system in the Bourgain space $X^{s,b}$.</abstract>
