供电公司投资规模模型研究

Investment Scale Model of Power Supply Company

当前宏观经济增长放慢,在国资委对企业业绩考核中经济增加值(economic value added,EVA)和资产负债率所占的权重越来越大,电网公司可用投资规模进一步减少。电网公司的战略目标是在实现社会责任的前提下追求经济效益,因此建立供电公司投资规模的数学模型对提高电网公司投资决策的合理性具有非常重要的意义。以重庆电网公司为研究对象,采用定性与定量相结合的系统化方法筛选指标,建立供电公司投资规模指标体系;应用层次分析(analytic hierarchy process,AHP)方法确定指标的权重,再对供电公司进行综合评价;最终根据子公司综合评价与投资规模的关系建立供电公司投资规模模型。以此作为电网公司投资分配决策的理论基础,实现电网企业的全面协调可持续发展,促进企业健康稳步地发展。
