[영문]This paper purports to examine the role and function of NGOs in social legislation processes of Korea since the economic crisis of 1997, focusing on NBLSA(National Basic Livelihood Security Act) movement. For this purpose, chapter two briefly examines the socio-economic crisis including mass unemployment and widespread pauperisation after the Korean economy received IMF bailout packages in 1997. Chapter three reviews recent social welfare reforms in Korea. Chapter four documents the role and function of NGOs in enacting the NBLSA, focusing on the activities of the Solidarity (the Solidarity for Enacting the NBLSA). Chapter five concludes that the movement for the NBLSA shows both possibilities and limitations.
