共享单车信用监管机制的行为经济学实验研究

共享单车具有一部分公共产品的属性，也同样面对着负外部性的问题。为了规范共享单车用户使用行为，信用监管机制和政府监管等解决方式被提出，但相关研究偏政策性，摩拜公司等共享单车企业已建立的信用监管机制实施效果不佳。运用行为经济学的前景理论、有限理性模型进行实证分析，通过经济学行为实验的方式模拟现实生活中公众对共享单车使用和损耗的状况，收集行为数据进行深入剖析信用监管机制对共享单车用户使用行为规范的效力；在实验前后对参与者进行问卷调查，将问卷调查的数据与实验行为的数据进行比对分析。实验表明，信用监管机制的引入有效规范用户使用行为，负面语境的信用监管机制对用户行为更有约束力，加入实时反馈比无实时反馈机制效果更好。

Experimental study on shared bike credit supervision mechanism in behavioral economics

Shared bikes have some properties of public products, while also facing negative externalities. In order to regulate the behaviors of users of shared bikes, the credit supervision mechanism and government supervision as well as other solutions have been proposed. However, the relevant research is too policy oriented, and credit supervision mechanisms established by shared bike companies such as Mobike have been ineffective in implementation. This paper will use the prospective theory of behavioral economics and limited rational model for empirical analysis, simulate the situation of the public’s use and damage of shared bikes in real life through economic behavioral experiments, and collect behavioral data for thorough analysis of the effect of credit supervision mechanism on regulating the behaviors of shared bike users. Meanwhile, participants are surveyed in questionnaire before and after experiment, and the data of SP and RP are compared and analyzed. The result shows that the introduction of credit supervision effectively regulates the behavior of users, with the mechanism in negative context being more binding on user behavior, and its effect being better after adding real time feedback than having no real time feedback mechanism in the credit supervision mechanism. 
