基于DEA模型的水产品加工业上市公司绩效评价研究

Performance evaluation on listed aquatic products processing companies based on DEA Model

论文运用数据包络分析中的C^2R模型对13家水产品加工行业上市公司进行绩效评价研究,测算了各公司的纯规模效率、纯技术效率和总体效率。评估结果表明在水产品加工行业上市公司中处于总体效率和纯规模效率前沿面上的公司占样本总数的30.7%,而有69.3%的公司在总体效率和纯规模效率方面仍未达到DEA有效。处在非DEA有效的公司都存在投入剩余或者产出不足。文中根据各公司的具体情况指出了改进的方向和途径,以有助于提高水产品加工类上市企业综合竞争力。

Utilize CCR model and BCC model of Data Envelopment Analysis(DEA) to measure the total,pure technological and scale efficiency of 13 listed aquatic products processing companies. The evaluation results indicate that the 30.7%of total aquatic product processing industry listed companies are in the total and pure efficiency frontier,while 69.3%of total companies has not yet reached DEA effective in total and pure efficiency aspect.The non-DEA effective companies all exist investment surplus and insufficient productivity phenomenon.The paper pointed the improvement direction and pathway by specific conditions of each company and thus helps improve overall competitiveness of listed aquatic products processing companies.
