How should the present socio-economic system be changed and be reorganized as a new system in the coming century? This paper is addressed to the examination of some proposed concepts to this question. We first briefly review the experiences concerning the experiments of socio-economic systems in the 20th century and summarize the lessons into the following three: market failure, government failure and 'grand' failure of planning. After some conceptual discussion related to the terms 'social economy' or 'the third sector', three types of socio-economic systems (American-type, 'social economy' -type, and 'social market' -type) are singled out, and their differences, characteristics and limitations are examined, respectively.
