以2007～2009年43家安徽省上市公司为样本,运用数据包络分析(DEA)方法测算了各家公司的技术效率与规模效率,结果发现整个安徽省上市公司生产效率逐年提升,但相对来说规模效率要更优于技术效率。根据分析结果,在今后工作中,对于技术效率低下的企业我们应该从引进先进技术、提高管理水平、加大研发投入、调整产品结构等方面着手改进;而对于规模无效的企业则要优化生产规模,发挥规模经济的作用。
Taking the 43 listed companies in Anhui province from 2007 to 2009 as a sample, the DEA method was used to calculate the technical efficiency and scale efficiency of each company. The results showed that the production efficiency of listed companies in Anhui Province increased year by year. However, Say the scale efficiency is better than the technical efficiency. According to the results of the analysis, in the future work, we should improve the technology inefficient enterprises by introducing advanced technologies, improving management level, increasing R & D investment and adjusting product structure. For inefficient enterprises, we must optimize production scale , Play the role of economies of scale.
