【摘要】：钢铁行业是国民经济重要的支柱型产业,1996年以来中国钢铁行业在产能上取得了飞速且长足的发展。但与此同时,巨大的能源消耗和较低的生产技术效率使中国钢铁工业陷入了“大而不强”的困境,这不但为国家带来能源安全和环境污染问题,且大量的二氧化碳排放为气候变化问题也造成了极大压力。本文基于工业企业微观数据,利用将能源使用和环境污染排放纳入其中的方向性距离函数模型对2001—2005年我国钢铁行业2973个企业级样本进行了能源环境效率测算,进而采用广义线性回归法对中国钢铁企业能源环境效率影响因素进行了计量回归分析。研究结果显示,2005年中国钢铁企业能源环境效率出现了一次严重倒退,钢铁企业所处地区、企业规模、企业所有制、生产产品种类、企业年龄和资本劳动比均对钢铁企业的能源环境效率有显著影响。
[Abstract]:The iron and steel industry is an important pillar industry of the national economy. Since 1996, China's steel industry has made rapid and rapid development in production capacity. But at the same time, The huge energy consumption and low efficiency of production technology make China's iron and steel industry into a "big but not strong" dilemma, which not only brings about energy security and environmental pollution for the country. And a lot of carbon dioxide emissions are also putting a lot of pressure on climate change. Based on the directional distance function model which includes energy use and environmental pollution emissions, the energy and environmental efficiency of 2973 enterprise class samples in China's steel industry from 2001 to 2005 was measured. Furthermore, the econometric regression analysis of the factors affecting energy and environment efficiency of Chinese iron and steel enterprises is carried out by using the generalized linear regression method. The results show that the energy and environment efficiency of Chinese iron and steel enterprises has experienced a serious retrogression in 2005, and the iron and steel enterprises are located in the region. The energy and environmental efficiency of iron and steel enterprises is significantly affected by the scale of enterprises, ownership of enterprises, types of products, age of enterprises and ratio of capital to labor.
