作为 20 世纪九十年代我国检察体制改革的产物，量刑建议自推出后便一直受到实务界和学界的广泛关注。自认罪认罚从宽制度全面推行以来，量刑建议机制作为认罪认罚案件中连结控辩审三方的重要环节，从内容到效力方面都发生着重要变革，在我国刑事诉讼体系中发挥的作用日益显著。在内容层面，量刑建议内容的明确程度不断提升，呈现出由概括刑、幅度刑向确定刑的渐进转变趋势。在法律效力方面，量刑建议的效力也得到了逐步的稳固和加强，从最初的无强制性到如今获得“类裁判结果”地位，正逐渐迈向类刚性效力的新高度。本文以确定刑量刑建议为研究核心，从基础理论和实践现状两个维度对认罪认罚从宽制度下确定刑量刑建议进行深入探讨，在剖析其理论基础、细究其运作机制的同时，也积极审视在实践中所面临的种种问题，力求探索出一条制度的完善路径。第一部分集中在确定刑量刑建议的基础理论研究，第1章为引言，对本文将要探讨的问题进行整体概览。第2章将介绍基础理论，首先对确定刑量刑建议的基本概念进行明晰，并且对“确定刑量刑建议”与“精准量刑建议”这一对在理论研究中经常被混淆的概念进行辨明。其次，探讨在目前两个“一般应当”立法设计下确定刑量刑建议的法律性质。再次，对确定刑量刑建议机制的域外制度建设进行介绍，内容将包含域外规则体系的建设和不同国家量刑协商的模式差异两个部分。在第2章的最后，将就确定刑量刑建议与以审判为中心改革的关系剖析及理论应用中的实践张力做出解读。 第二部分包含第3章和第4章两个章节，第3章以确定刑量刑建议机制下控辩审三方刑事诉讼权能的演化为切入口，探寻目前认罪认罚从宽制度中确定刑量刑建议的盛行是如何改变及重新形塑控诉、审判、辩护三方权能，以及这些转变对我国认罪认罚从宽制度的实施会带来哪些影响，并且针对可能产生的消极影响，在第4章中探究相应的解决之道。

As a product of the reform of China‘s prosecutorial system in the 1990s, sentencing recommendations have been the subject of extensive attention from both the practical and academic communities since their introduction. Since the full implementation of the system of leniency in plea bargaining, the mechanism of sentencing recommendations under the system of leniency in plea bargaining has undergone important innovations in terms of content and effectiveness, and its status in China‘s criminal procedure system has become increasingly prominent.At the content level, the clarity of sentencing recommendations has been increasing, showing a gradual shift from generalized sentences and ranges to definitive sentences. At the same time, the legal effect of sentencing recommendations has also experienced a gradual stabilization and enhancement. From the initial non-compulsory, to today‘s "class adjudication results" status, its effectiveness is gradually moving towards the rigidity of the new height of the effectiveness of the class. In judicial practice, its position is increasingly prominent, become more and more important.This paper to determine the sentence as the core of the research, from the basic overview and practice of the current situation of two dimensions, the plea leniency system under the determination of the sentencing recommendations into an in-depth discussion, aimed at a comprehensive analysis of its theoretical basis, practical application and problems, and try to explore the path of its improvement.The first part of the study mainly focuses on the basic theory of determinate sentencing recommendations, and in Chapter 2, the basic concept of determinate sentencing recommendations is firstly clarified, and the concepts of “determinate sentencing recommendations” and “precise sentencing recommendations” are often confused in the theoretical study. Secondly, it explores the differences between the two current concepts of “determinate sentencing recommendations” and “precise sentencing recommendations”. Secondly, it explores the legal effect of determinate sentencing recommendations under the current two “general should” legislative designs. Thirdly, an introduction to the extraterritorial institutional development of the mechanism of determinate sentencing recommendations is provided, comprising two parts: the development of extraterritorial systems of rules and the differences in the modalities of sentencing consultations in different countries. At the end of Chapter2, an interpretation will be made on the dissection of the relationship between determinate sentencing recommendations and trial-centered reforms and the practical tensions in the application of the theory. The second part will take the evolution of the power of prosecution, defense and trial in criminal proceedings under the mechanism of determinate sentencing recommendation as an entry point, by exploring how the prevalence of determinate sentencing recommendation in the current plea leniency system has changed and reshaped the power of prosecution, trial, and defense, as well as what impacts these transformations have had on the implementation of China‘s plea leniency system, and by exploring the corresponding solutions.
