【摘要】：石化行业是关系我国国家安全的战略性支柱产业，对于我国国民经济的发展具有重要作用。虽然自改革开放以来我国石化行业取得了巨大的进步，但目前仍处于改革的初步阶段。经营效率作为衡量我国石化行业整体运行水平和综合实力的重要指标，与发达国家相比还存在一定的差距，并且国内对我国石化企业经营效率的研究较少，因此，石化上市公司经营效率的研究对于提高行业整体经营效率具有紧迫性和重大的现实意义。针对我国石化行业是多投入多产出系统，在对评价方法进行比较之后选取数据包络分析方法作为经营效率评价方法。在相关经营效率评价理论的支撑和一定原则框架内，，选取12家石化上市公司作为研究样本，以主营业务收入成本、三项期间费用、员工数量作为投入指标，以主营业务收入、总资产作为产出指标，构建石化上市公司经营效率评价指标体系。基于12家石化上市公司2007-2011年的数据，首先，运用数据包络分析模型对技术效率、纯技术效率、规模效率进行静态评价；其次，运用基于数据包络分析模型的Malmquist指数对全要素生产指数进行动态评价，通过静态和动态相结合的方式进行实证分析。根据实证分析的结果及石化行业发展的现状，提出提高我国石化行业经营效率的建议。
[Abstract]:Petrochemical industry is a strategic pillar industry related to China's national security and plays an important role in the development of our national economy. Although China's petrochemical industry has made great progress since the reform and opening up, it is still in the initial stage of reform. As an important index to measure the overall operation level and comprehensive strength of petrochemical industry in China, there is still a certain gap between China's petrochemical industry and developed countries. The research on the operating efficiency of listed companies in petrochemical industry is of great urgency and practical significance for improving the overall operating efficiency of the industry. In view of the multi-input and multi-output system in petrochemical industry of our country, after comparing the evaluation methods, the data envelopment analysis method is selected as the operational efficiency evaluation method. In the framework of the related operational efficiency evaluation theory and certain principles, 12 petrochemical listed companies are selected as the research samples, with the main business revenue cost, three period expenses, the number of employees as the input index, and the main business income. As the output index, the total assets set up the evaluation index system of the operating efficiency of the listed companies. Based on the data of 12 listed petrochemical companies from 2007 to 2011, firstly, we use the data envelopment analysis model to evaluate the technical efficiency, pure technical efficiency and scale efficiency. The Malmquist index based on the data envelopment analysis model is used to evaluate the total factor production index dynamically, and the empirical analysis is carried out through the combination of static and dynamic methods. According to the results of empirical analysis and the present situation of petrochemical industry development, the paper puts forward some suggestions to improve the operation efficiency of petrochemical industry in China.
