Innovation achievements of this dissertation are mainly in the content and the method, namely: presents the content of EAP thoroughly and systematically; reviews the cost, utility and empirical studies of EAP; investigates the cost and utility of EAP theoretically, conducts the typical survey of the EAP implementation of a domestic enterprise; establishes multivariate linear regression equation of EAP utility; sets up an allocation model of EAP cost through Analytic Hierarchy ProcessThis dissertation\'s conclusion is that EAP cost is related to the time and frequency of EAP used by employee under the fixed cost, the tendency of using EAP is related to demographic characteristics and other factors, the utility of EAP is related to the personal preference of using EAP at least, the utility of EAP is leastwise related to 7 factors, the relationship with the supervisor is the most important factor in the workplace, personal health is the largest part of EAP cost.

本文的创新成果主要是内容上的创新和方法上的创新：对EAP的内容进行了全面、系统的梳理；对EAP的成本、效用和实证研究进行了综述；对EAP的成本、效用进行了理论上的探讨；对国内企业实施EAP的情况进行了典型调查；建立了EAP效用的多元线性回归方程；用层次分析法建立了EAP的成本分摊模型。本文得出的结论是：在固定成本不变的情况下，EAP的成本与员工使用EAP的时间及次数有关系；EAP的使用倾向与人口统计学特征和其它因素有关；EAP的效用至少与个人对EAP的使用偏好有关；EAP的效用至少与7个因素相关；与上级的关系是工作场所中最重要的因素；个人的身体健康是EAP成本中花费最大的部分。
