In this paper we present a two-field inflation model, which distinguishesitself with a non-canonical kinetic lagrangian and comes from the large volumeapproach to the moduli stabilization in flux compactification of type IIBsuperstring on a Calabi-Yau orientifold of $h^{(1,2)} > h^{(1,1)}\geq 4$. TheK\"ahler moduli are classified as volume modulus, heavy moduli and two lightmoduli. The axion-dilaton, complex structure moduli and all heavy K\"ahlermoduli including the volume modulus are frozen by nonperturbatively correctedflux superpotential and the $\alpha^\prime$-corrected K\"ahler potential in thelarge volume limit. The minimum of the scalar potential at which the heavymoduli are stabilized provides the dominant potential energy for the survivedlight K\"ahler moduli. We consider a simplified case where the axioniccomponents in the light K\"ahler moduli are further stabilized at the potentialminimum and only the geometrical components are taken as the scalar fields todrive an assisted-like inflation. For a certain range of moduli stabilizationparameters and inflation initial conditions, we obtain a nearly flat powerspectrum of the curvature perturbation, with $n_s\approx 0.96$ at Hubble-exit,and an inflationary energy scale of $3 \times 10^{14}$ GeV. In our model,significant correlation exists between the curvature and isocurvatureperturbations on super-Hubble scales so that at the end of inflation a greatdeal of the curvature power spectrum originates from this correlation.
