For the study of Taiwan's universal service policy on the zone with uneconomic public phone, this paper uses Date Envelopment Analysis (DEA) and Modified Malmquist Index (MMI) to evaluate the production efficiency of its public phone. Then, this paper tests the hypotheses that there is the agency problem with Taiwan's universal service providers and its subsidy mechanism, its population density and its area density of public phone, and its special regulation in remote districts would influence the production efficiency of its public phone. The results are that its public phone has high technology efficiency and low scale and production efficiency, Taiwan's universal service providers has the agency problem, its subsidy mechanism, its population density and its area density of public phone had significantly influence on the production efficiency of its public phone, but its special regulation in remote districts hadn't.
