Based on analyzing the macro and micro factors in Singapore¡¦s social welfare policy, this thesis proposes the frame work of ¡§state corporatism¡¨ to explain Singapore¡¦s social welfare policy. Since 1959 Singapore be independent from Britain, Lee Kuan Yew had led the PAP government in an authoritarian style and promoted a paternal social welfare. The core ideas of Singapore¡¦s social welfare policy, voluntarism and communitarianism, strongly related to the personal ideology of Lee Kuan Yew and the confucian society in Singapore. In the macro background of nation¡¦s level, we can divide the society into the subgroups as ethnic groups, opposition parties, class groups and voluntary welfare organizations (VWOs). These four groups worked through the four phrases in Singapore¡¦s social welfare policy : pre-corporatism period, exclusive corporatism period, inclusive corporatism period and extrinsic corporatism period. The whole presentation of Singapore¡¦s social welfare policy can be observed from their negotiation, interaction and bargaining with the government. This thesis conludes that the strategy of Singapore¡¦s social welfare policy is ¡§using greater quantity and quality of voluntarianism to fill up the retreat of state¡¨. Therefore in the history of Singapore¡¦s social welfare policy, when comparing to the other social groups, the extent of VWOs corporating with the government was much greater than the others and their influential power in social welfare policy during these four periods turned from weak to moderate, and strong eventually.
