我国核电上市公司技术效率研究--基于超效率DEA模型的实证分析
Empirical Research on Nuclear Energy Listed Companies’ Technical Efficiency Based on SE-DEA Model
摘要
Abstract
Faced with environmental pollution and energy depletion, improving nuclear energy efficiency is essential. This article studies nuclear energy technology efficiency from listed companies. Use SE-DEA model to measure and analyze energy listed compa-nies’ technical efficiency from 2009 to 2014. On this basis, use Tobit model to study factors of nuclear energy listed companies’ tech-nical efficiency from financial and non-financial aspects. At last, give some suggestions. Studies show that:short-term solvency, profit-ability, company size have a significant positive impact on technical efficiency of energy listed companies, while long-term solvency has a significant negative impact. Operating capacity, education level, technical constitution, research and development capabilities have no significant impact. Therefore, nuclear energy listed companies should reduce the company’s long-term liabilities appropriately, im-prove the company’s current liabilities appropriately, improve the company’s profitability and expand the size of the company.关键词
