情绪智力这一概念自20世纪90年代提出后，关于情绪智力的研究在管理学领域中一直备受青睐。Goleman的情绪智力理论将情绪智力视为决定个体成败的一个关键因素。国内外许多学者的研究也证实了情绪智力和工作绩效之间存在显著的相关性，情绪智力可以预测工作绩效。但是对医药领域客户服务人员的研究相对较少。本文通过对A公司客户服务部的现状分析和员工访谈，以问卷调研和数据分析的形式，探讨A公司客户服务部员工情绪智力和工作绩效的相互关系，并得出以下结论：

1.客户服务部员工情绪智力水平还需提高，情绪运用能力与年龄相关，为企业人员招聘与选拔提供借鉴。

2.情绪智力与工作绩效呈正向相关，其中他人情绪的识别与评价和情绪运用两个维度对工作绩效有显著的影响。

根据研究分析结果，提出基于人力资源管理的客户服务部员工情绪智力的开发与提升，分别从员工招聘、员工培训、企业文化和自我提升等方面进行系统论述，为客户服务部全面提升工作绩效提供实践依据。

Since the concept of emotional intelligence was proposed in the 1990s, research on emotional intelligence has always been highly favored in the field of management. Goleman's theory of emotional intelligence regards emotional intelligence as a key factor determining an individual's success or failure. Many scholars at home and abroad have also confirmed the significant correlation between emotional intelligence and job performance, and emotional intelligence has a positive impact on job performance. However, there is relatively little research on customer service personnel in the pharmaceutical field. This article explores the relationship between emotional intelligence and job performance in Company A's customer service department through an analysis of the current situation and employee interviews, as well as questionnaire research and data analysis. And draw the following conclusion:

1.The emotional intelligence level of employees in the customer service department still needs to be improved, and their ability to apply emotions is related to their age, providing reference for the recruitment and selection of enterprise personnel.

2.Emotional intelligence is positively correlated with job performance; Among them, the recognition and evaluation of others' emotions in emotional intelligence, as well as emotional application, have a significant impact on job performance.

Based on the current situation analysis and data analysis of the Customer Service Department, this paper proposes the development and improvement of emotional intelligence of the employees of the Customer Service Department based on human resource management, and systematically discusses employee recruitment, employee training, corporate culture and self-improvement, providing a practical basis for the Customer Service Department to comprehensively improve its work performance.
