我国学界对刑事司法的研究很大程度上还停留在“对策法学”的层面。本文从比较法视角对美国刑事司法的研究成果进行系统梳理,全面介绍美国社会科学化的刑事司法研究的特征,以自变量与因变量的因果关系为基础,在司法实践中调整司法理论。这种社会科学研究方法对促进我国相关研究有重要的借鉴意义。 The study of criminal justice in our country has largely remained at the level of “countermeasure law”. This article systematically sorts out the research achievements of criminal justice in the United States from the perspective of comparative law, and comprehensively introduces the characteristics of criminal justice research in the social sciences in the United States. Based on the causal relationship between independent variables and dependent variables, it adjusts judicial theory in judicial practice. This kind of social science research method has important reference significance to promote our country related research.
