With recent penetration of the Internet and a proposal from the central government for an e-local-government, local governments, local companies, local associations and local residents are more and more aware that transmitting local information to residents and potential visitors via the Internet can contribute to regional vitalization and enhance the quality of residents' life. Local information composed of information from the local government, local business organizations, local associations and local residents can be provided through a “ local portal site” and this site may be operated through a public private partnership (PPP) . Some advanced local governments have already started “ local portal site” services by applying PPP. However, there are some issues on this way of providing local information. Our study aimed to identify how residents evaluate the credibility of information providers. Based on questionnaire surveys conducted in Itami City in 2008 and Minami-Awaji City in 2009, we reveal the residents' value structure on the credibility of operators for local portal sites and derive some policy implications. In this study, we applied the weight evaluation method of the Analytic Hierarchy Process. Our results show that both citizens of Itami and Minami-Awaji value credibility, public-spiritedness and technological capacity as important factors for operators of public-private local portal sites, while operators' vitality and strength of organizations are less highly regarded. Also, regarding “ credibility” that ranked first in both Itami and Minami-Awaji, operators reliability, response capability and past achievements were identified as key elements regarded by citizens as “ sources of credibility” . Factors such as degree of recognition, authority and strength of an organization contributed less to the regard of citizens for a local portal site operator's credibility. Also, the fact that the survey results in Minami-Awaji showed similar tendencies to the results in Itami suggests that regional disparities are relatively limited. Based on previous studies that point out local portal site operators must attract enough visitors to pay for the running costs within two to three years of government funding, we aim to further analyze the possibilities of local portal sites including social networking service (SNS) .
