We have analyzed large-amplitude quadrupole collective dynamics in neutron-rich nuclei ^<30-36>Mg using the five-dimensional quadrupole collective Hamiltonian approach. The collective Hamiltonian is microscopically derived with the constrained HFB plus local quasi-particle RPA method. Enhancement of the quadrupole collectivity from ^<30>Mg to ^<34>Mg is well described by the calculation. The shape transitional behavior in the ground band and the shape coexistence/mixing properties in the ground and excited 0^+ states are analyzed.
