我国民营钢铁企业信息化影响因素分析

信息化是实现工业化和现代化的必然选择,信息化为我国钢铁工业实现现代化提供了重要机遇。本文结合我国钢铁企业信息化建设的现状,在对国内外关于企业信息化影响因素作简要回顾的基础上,以我国民营钢铁企业信息化影响因素为分析对象,从资金、管理、人力、技术环境4个方面进行了具体分析,在此基础上提出了增强中国民营钢铁企业信息化的4个对策,即：改变粗放管理模式,建立良好公司治理机制;树立科学发展观,增强环保意识;加强技术改造,提高企业综合竞争力;措助信息化,延伸产业链,推进企业集团化。     

演化经济学框架下环保技术扩散研究——以熔炼压缩炼铁技术的扩散为例

在分析传统框架下扩散模型的局限性及环保技术扩散的特殊性的基础上,以SRT的扩散为例,尝试用演化经济学的框架来探讨环保技术的扩散问题。技术的扩散是技术竞争的动态演化、企业家和异质采用者、制度和政治等共同作用的结果,因此,从一个更广泛的演化经济学的框架来理解技术扩散,特别是环保技术的扩散是很有必要的。     

世界铁矿资源分布对我国钢铁工业发展的影响

钢铁工业是国民经济的基础性产业。随着我国钢铁产量的不断提高,对铁矿石的需求也在逐年增加,尽管我国铁矿石产量一直大幅度提高,但仍不能满足我国钢铁工业发展的需要,使得进口铁矿石的数量必须不断增加．我国也因此成为世界上进口铁矿石最多的国家。而世界铁矿资源分布比较集中,对我国钢铁工业的发展有直接的影响。根据铁矿资源的分布情况,分析我国钢铁工业在原料供需方面所面临的问题,并提出一些相应的对策。     

The impact of differential power pricing policy on firm productivity in China: Evidence from iron and steel firms

The differential power pricing (DPP) policy is implemented as an important measure to curb the unrestrained development of high-energy-consuming industries, optimize industrial structure, and promote the upgrading of industrial technology. However, it is unclear how the DPP policy affects the productivity of regulated firms. Using the difference-in-differences approach, this study is the first to investigate empirically the DPP policy’s impact on the productivity of China’s iron and steel firms—a top carbon emitter. The results show that the DPP policy has a significant negative effect on the productivity of iron and steel firms, leading to a 1.20% per annum decrease in the total factor productivity growth of these firms, primarily because the policy significantly hinders firms’ scale efficiency. Considering the heterogeneity of firms, the impeding impact on large-scale and state-owned firms is less than that on the firms of full sample. To curb the irrational expansion of energy-intensive industries and eliminate backward production capacity, the government should implement the DPP policy more precisely according to the heterogeneity of firms, and other auxiliary measures, such as cost compensation for innovation, are also recommended.
