“利用职务上的便利”和“利用本人职权或地位形成的便利”将“利用职务之便”作为表征，共同成为受贿罪构成要件要素。虽然刑法对于“利用职务之便”的立法经历较为反复，但基本走向是逐渐严密、渐趋完善。受贿罪包括普通受贿罪和斡旋受贿罪两种形式，广义的“利用职务之便”作为关联性要件，将“利用职务上的便利”与“利用本人职权或地位形成的便利条件”两种形态加以言语凝练，更方便理论研究和司法实务的应用。随着高压反腐纵深推进，受贿罪的“职务之便”表现形式更加多样化和隐蔽化，司法实务中对“利用职务之便”的认定难度越来越高，主要存在涵摄范围边界模糊、判定角度局限、法益保护立场不准确等三个方面认定难题。 刑法理论学界关于“利用职务之便”的认定学说众多、各有特色，“利用职务上的便利”包括职务范围内的权力说、便利条件说、职务范围内的权力说与纵向制约说的混合说、抽象职务权限说等学说；“利用本人职权或地位形成的便利条件”包括影响说、基于身份（承诺）说、类似教唆犯说、制约说等学说，但各种学说尚存继续解释的空间。“利用职务之便”的认定应当在受贿罪公正性法益的视角下，总结“利用职务上的便利”和“利用本人职权和地位上形成的便利条件”两种形态同质性特征，探明“利用职务之便”本质上是对公权力产生实质影响，进而对公权力实质影响说的本体进行规范构造。 职务行为公正性法益是公权力实质影响说的法益根据和基础，相比较职务行为的不可收买性，可以从公正性说含义边界、内部逻辑、目的理性、解释效能四个方面确证受贿罪的保护法益。公权力实质影响说指行为人能够对本人职务上的公权力或其他国家工作人员职务上的公权力产生实质影响，从而将职务公平公正行使置于贿赂影响之下，进而对公正性法益产生侵害危险。公权力实质影响说包括行为主体、行为对象、行为本体三个层面，司法实务中可以通过公权力实质影响说的规范构造解决非典型性受贿案例认定难题。

"Taking advantage of the convenience of his position" and "taking advantage of my power or position" will take "taking advantage of my position" as a representation， and jointly become the constituent elements of the crime of taking bribes. Although the legislative experience of "taking advantage of his position" is repeated， the basic trend is gradually strict and gradually perfect. The crime of taking bribes includes two forms of ordinary bribery and the crime of mediation， and the two form of "using the convenience of the convenience of the position" and "taking advantage of the position or position"， which is more convenient for the application of theoretical research and judicial practice. With the deepening of high-pressure anti-corruption， the expression form of "position" of taking bribes is more diversified and concealed. In judicial practice， it is increasingly more and more difficult to identify the position of "taking advantage of the position". There are mainly three difficulties in the fuzzy boundary of the scope， the limited perspective of judgment， and the inaccurate position of legal interests protection. In the field of criminal law， there are many theories of different opinions， including the theory of power， the use of power or position， including influence， identity (commitment)， solicitation， restriction， etc."Take advantage of position" that should be under the perspective of bribery justice law， summarize "use of convenience" and "using personal authority authority and position of convenient conditions" two kinds of form homogeneity characteristics， proved "use position" is essentially a substantial effect on public power， and then the substantial influence of public power said ontology specification structure. The justice benefit of duty behavior is the basis and basis of the substantive influence of public power. Compared with the bribery of duty behavior， the protection benefit of Crime of Bribery can be confirmed from four aspects: fairness meaning boundary， internal logic， purposeful rationality and explanatory efficiency. The substantial influence of public power means that the actor can have a substantial influence on the public power or the public power of other state functionaries， so as to put the fair and just exercise of the position under the influence of bribery， and then endanger the infringement of the impartiality and legal interests. The substantive influence of public power includes three levels: the subject of behavior， the object of behavior and the behavior ontology. In judicial practice， the difficult problem of identifying atypical bribery cases can be solved through the normative structure of the substantive influence of public power.
