It was aimed here to investigate the present conditions and features of quasi-markets of the local initiative social service as a whole and of its sub-categories through ‘population’ data on service providers, their types, registered regions, number of users, voucher payments, etc. First, the capacity of providers was examined in three dimensions: quantitative scale, financial security and consistency, and quality of management. Second, it was attempted to understand characteristics and changing nature of quasi-markets of 8 sub-categorical service areas in recent three years. As a whole, providers are increasing mainly by for-profit players whilst the small-scale of the market of local initiative social services has not been enlarged. Thus competition between providers becomes tougher making the rate of entrance and exit of players high, which would lower the consistency of service provision and ultimately the quality of service. It is imperative to question how we can enlarge the scale of the market and how we should manage the number of providers in the adequate level in this pseudo-market, both of which relate to the unit-cost policy and the provider-registration policy, respectively. It was also found that we might need different approaches according to services and regions.
