The social service delivery system has had problems of low efficiency and effectiveness because of service discontinuity, redundancy and incomprehensiveness for a long time. A model of Health and Social Welfare Office was implemented in order to solve these problems but stopped its operation without being expanded nationally in 1990's. In 2004 a new experiment of the Social Welfare Offices was launched to solve the problems. One of the important goals of the new experiment of the Social Welfare Offices was to reinforce autonomy and accountability of the local governments in providing various social services and social welfare benefits, to deliver coordinated services and to activate participation of the local people for development of social welfare through construction of the cooperative system among the central government, the local government and the social welfare institutions in the private sector. This paper analyzed how different linkage of financial resources in the social service network for the elderly was between the experiment and the control areas during the second experimentation period of the social welfare offices. It compared the organizational characteristics of the social service network for the elderly, frequency and density of networking, and degree centrality of the networks between the experiment and control areas. The findings show that the social welfare offices are playing a very important role in activating networking. However, it is difficult to conclude that the experimentation caused the difference in networking between the two areas because the research design did not take before and after comparison for the experiment and control areas. Discussion can be advanced if the results of the qualitative study would be compared with the findings of this study.
