Through the investigation of the governmental departments and agents in pilot areas of China, the system comprised of 13 secondary indicators and 5 primary indicators including agent’s strength and performance, level of project organization and management, agent management principle, agent management target and supporting measures, and agent overhead expenses is put forward. The system is comprehensively evaluated by way of Likert5points. Then through applying fuzzy entropy, the weights of indicators are measured with conditional entropy, and the levels of agents are ranked with doublepoint method which can avoid the disadvantages of subjective judgments, and thus improve the objectivity and accuracy of agent evaluation. At last, the validity of the system is confirmed by a project example.
