改变回采工艺方法的选择与实践

随着煤炭开采地质条件的变化,改变回采工艺方法是必要的。峰峰集团羊渠河矿8230工作面原为轻放工作面,由于工作面内断层多、地质条件复杂,因此影响推进速度。经矿、集团公司研究决定,将轻放工作面改为高档普采工作面,此实践取得了良好的效果。一、工作面概况1.8230工作面位于三     

高硫减压渣油加工方案的技术经济比较

对中国石化齐鲁分公司高硫减压渣油两种生产方案,即减压深拔工艺生产重交沥青和VRDS-FCC组合工艺生产轻质油品进行技术经济比较.结果表明:在公司裂解原料不能完全自给的前提下,VRDS-FCC组合工艺的单位利润优于减压深拔工艺,但随着重交沥青价格的上升,VRDS-FCC组合工艺的优势将逐渐减弱.     

Investigating the Impact of Income on Savings Using a Chinese Household Level Dataset

This article uses the China Household Financial Survey (CHFS) to examine the savings behavior of Chinese Households. Using a standard cross-sectional empirical approach to modeling permanent and transitory income, we show that one way of explaining the relative high savings rate in China is by recognizing that in fast growing economies, individuals may have higher transitory income from which they save a large proportion. The estimation also contains a range of household specific variables which can be used to understand the impact of socio-economic characteristics such as urban vs rural dwelling, age, and the educational level.     

Government Stakes as an Insurance Policy: Evidence from Seasoned Equity Offerings of Chinese Firms

While privatization has attracted much more attention in the literature, one type of reverse privatization, a privately-controlled firm inviting government ownership as its minority shareholders, is neglected in the literature. Using large-scale census firm data from China, we investigate the determinants of this kind of reverse privatization and its impact on firm performance. We find that (1) the decision of reverse privatization by Chinese private firms is affected by local political risk, firm-level financial characteristics, and industry-level characteristics, (2) the reverse privatization significantly affects the firm’s performance, which is measured in different proxies but the effects are not consistent, and (3) moreover, we find that the benefit of reverse privatization decreases as government ownership increases. Our results suggest that the prevalence of reverse privatization in China is a political outcome, which is affected by the trade-off of political risk and political privilege. Our work suggests that political risk and political considerations are the main driving factors of privatization, or its opposite, reverse privatization. Reverse privatization, to some extent, is a rational choice in some transition economies. Our findings offer clear policy implications to the nationalization phenomenon taking place around the world recently.     

高管经管教育背景与企业内部薪酬差距

本文考察高管经管教育背景对企业内部薪酬差距的影响,并进一步分析了其内在作用机制.研究发现:经管教育背景显著提高内部薪酬差距.为控制潜在的双向因果关系,本文使用行业内其他高管的平均经管教育背景进行工具变量检验,结论依然成立.进一步的机制研究发现,具有经管教育背景的董事长,以及具有经管专业博士学位的企业高管所发挥的作用更大.且这一影响在非国有企业、资本密集型企业,以及非管制行业及低集中度行业中表现更为突出.本文结论为深入理解企业内部薪酬制度及其影响因素提供了经验证据.
