Mixed crowdsourcing is increasingly becoming the main organizational model of domestic crowdsourcing platforms. However, research on the interpretation of winning performance fails to focus on the persuasive effect of the credibility of the contractor's information source on the contractee's decision making. Based on source credibility theory (SCT), this study constructs a model of the factors influencing the contractor's bid-winning performance based on three aspects—credibility, professionalism, and attractiveness—and examines the moderating effect of positive contractor evaluations from previous tasks on the bid decision. The results reveal that integrity guarantee and contact authentication (which belong to the credibility dimension), as well as ability level and professional identity (professionalism dimension) positively affect the contractor's bid-winning performance, and that an inverted-U-shaped relationship exists between the number of services displayed by the contractors (attractiveness dimension) and bid-winning performance.

混合众包正日益成为国内众包平台的主要组织模式。但是，关于获胜绩效解释的研究未能集中于承包商信息来源的信誉对承包商决策的说服力。基于来源可信度理论（SCT），本研究基于信誉，专业性和吸引力三个方面，构建了影响承包商中标绩效的因素模型，并检验了先前任务对承包商积极评价的调节作用。出价决定。结果表明，完整性保证和联系人身份验证（属于可信性维度）
