EVA经营业绩评价是一个综合的财务管理度量系统,能够用于资本预算、财务计划、目标设定、业绩衡量、股东交流等。经济增加值是指企业税后净营业利润与该企业加权平均的资本成本间的差额,是为出资人创造的“真正的利润”。它的特点在于揭示了企业经营效率和资本使用效率,其最大的亮点在于不仅剔除了债务成本,还考虑了股权投资的机会成本,消除了在传统会计利润下企业认为“股东资本免费”的弊端,更能准确反映企业价值创造水平。本文从EVA业绩评价的基本理论出发,对EVA的基本思路、理论框架、价值管理体系、优缺点等进行了详细的阐述,并在分析Z公司经营业绩评价体系的基础上,引入EVA对其经营者业绩评价体系进行了优化设计,并提出了切实可行的实施保障措施。
