The present study investigates developing of the services of private telecommunication offices in provinces of Iran. The objectives of this study include identifying the factors affective on developing the services of the studied offices, evaluating the amount of the centralization of the offices' services and investigating the levels of developing their services in Iran's provinces. The method of the study is descriptive-analytical and to access the objectives of the study, the models of factor analysis, technique to measure the concentration level, Cluster Analysis and Multivariate regression were employed. The findings of the research indicate that by reducing 55 created indices to 40 selective indices, 6 significant factors which explain 67.2 percent of the variance of the population, are affective on developing the services of private telecommunication offices. The amount of centralizing the studied services indicates the maximum of balance in the factor "telephone conversations" and lack of balance in factor "offices insurance coverage". Based on the studied factors, Tehran Province almost allocates to itself the highest centralization of the factors. In terms of performance development, 4 provinces in the upper-development level, 10 provinces in the upper-intermediate level, 7 provinces in lower-intermediate level and 10 provinces in the lower-development level are located. The interests obtained from the performance of private telecommunication offices to be more balanced; multivariate regression predicts the influence of the factor "functional-institutional" more than those of other factors.
