Construction of an evaluation system for the service capabilities of government to business (G2B) web portals

On the basis of analyzing both domestic and foreign evaluation systems for the e-government and also taking into account of the current situation of government portals in urban centers, the paper is aimed to construct an evaluation system primarily for the measurement of the service capability of business-oriented G2B portals of local governments in general and those G2B portals of the new development zones in particular. This system is composed of 6 first tier indicators, 18 second tier indicators and 90 third tier indicators. And the weight of each indicator is determined by Delphi Method and Analytic Hierarchy Process (AHP) Method. Subsequently, we used this system to evaluate the government portals of Tianjin Binhai New Area and Shanghai Pudong New Area and proved to have the desired practicability.
