Empirical analysis based on related statistical data during 1990—2010 indicates that China’s judicial corruption has the external characteristics of dereliction of duty, highside power, right rentseeking organization, administrative business and longterm business and so on and has the inner characteristics of excessive administration of judicial system. The basic framework for preventing judicial corruption should include such four aspects as relatively independent judicial system, litigious system by taking procedural justice as core, judicial monitoring system by taking prosecutorial power as core and professional ethnic system with clean and selfdiscipline.
