摘要
数据包络分析方法是一种用于评价决策单元相对有效性的实证方法,近年来已经广泛应用于各行各业的绩效评价。本文在CCGSS模型基础上,加入并列结构,构造出并列结构的CCGSS模型(PCCGSS),以克服传统CCGSS模型忽视决策单元内部结构的不足。利用改进模型对中国各省份的能源利用效率进行评价,结果表明:我国各省市能源利用效率低下,东部发达地区与中、西部地区能源利用效率都存在较大提高空间;能源利用低效的主要原因不仅在于技术和人才的缺乏,还在于节能环保措施并未得到持续的贯彻。
DE A(data envelopment analysis) is an empirical method which is used to evaluate the relative efficiency of decision- making units(DMUs).A parallel structure CCGSS model(PCCGSS) which takes the operation of individual components into account in calculating the efficiency of the system is developed in this paper.This helps the decision maker identify inefficient components and make subsequent improvements.The model is applied to evaluate the energy efficiency of Chinese provinces.The empirical results suggest that most provinces in China have low energy efficiency,and continued implementation of energy- saving measures is a necessity.
