It is necessary to analyze the anti-terrorism performance of Taiwanpsilas security system after September 11, 2001 attacks. We use three stage data envelopment analysis model that Fried et al. (2002) developed, getting intelligence performance of the Investigation Bureau of the Ministry of Justice, to discuss the ability of anti-terrorism in Taiwanpsilas national security system. Putting 10 outputs, 2 inputs and 42 environment variables into this model, we find out output slacks and remove environmental impacts to intelligence. As a result, most of local field offices get higher efficiency scores compared with first stagepsilas DEA result. That means most of local field officespsila intelligence works with effective management. Furthermore, we analyze total factor productivity and find the change of intelligence performance coming from efficiency improving and technology degenerating. It seems Investigation Bureau of the Ministry of Justice works efficiently with traditional human resource management, yet could not deal with technical shock like new type of terrorism. We suggest that security institutions should train employees with advanced technology to overcome Taiwanpsilas security system deficiency.
