进一步落实科学发展观实现中国能源可持续发展——访国家能源领导小组办公室副主任徐锭明

能源行业落实科学发展观,一是必须坚持以人为本,二是必须坚持发展.要根本解决国内能源资源缺乏、环境压力大、安全隐患多、能源效率低等重大问题,必须及时调整产业结构,转变经济增长方式,控制高耗能产业发展,引导人们转变消费观念和生活方式.必须坚定不移地贯彻"节能优先,效率为本;煤为基础,多元发展;立足国内,开拓海外;统筹城乡,合理布局;依靠科技,创新体制;保护环境,保障安全"的能源工作指导方针,确保能源工业能够节约发展、清洁发展、安全发展、实现可持续发展.

我国上市公司资本结构影响股权代理成本的实证分析

公司资本结构是公司治理结构的重要方面,它对公司代理成本有着直接的影响。本文对1990—2003年上市公司资本结构影响股权代理成本的实证分析表明,经营者持股比例与股权代理成本呈显著负相关;负债融资比例、法人股比例和第一大股东持股比例与股权代理成本呈不显著负相关;国家股比例和流通股比例与股权代理成本呈较显著正相关。这些研究结论表明,资本结构对股东、经营者和债权人之间的契约关系有着直接的影响,完善资本结构是完善我国上市公司治理结构从而降低代理成本的重要途径之一。     

析《税收征管法》第三十八条及相关规定

设置税收保全的目的 修订后的<税收征管法>在为税务机关增设如税收保全、税收行政强制执行、离境清税、代位权与撤销权、税收优先权等许多权力的同时,也增加了诸多限制性条件,特别是程序性的限制,以体现依法治税、税收法律主义的要求.这表明,虽然权力增设的目的是确保国家税款不因纳税人的干扰而流失,使税收债权充分实现,但是税务机关在保证国家税款及时足额征收的前提下,并不能藉此对相关纳税人进行惩罚而造成额外的负担或损失.

Revisiting the Miles and Snow strategic framework: uncovering interrelationships between strategic types,capabilities, environmental uncertainty,and firm performance

The Miles and Snow strategic type framework is re‐examined with respect to interrelationships with several theoretically relevant batteries of variables, including SBU strategic capabilities, environmental uncertainty, and performance. A newly developed constrained, multi‐objective, classification methodology is modified to empirically derive an alternative quantitative typology using survey data obtained from 709 firms in three countries (China, Japan, United States). We compare the Miles and Snow typology to the classification empirically derived utilizing this combinatorial optimization clustering procedure. With respect to both variable battery associations and objective statistical criteria, we show that the empirically derived solution clearly dominates the traditional P‐A‐D‐R typology of Miles and Snow. Implications and directions for future research are provided. Copyright © 2004 John Wiley & Sons, Ltd.     

An Analysis of Trade Patterns and the Effects of the Real Exchange Rate Movements in East Asia

This article investigates the patterns of vertical specialization in trade among China, Japan and Korea, and the effects of real exchange rate fluctuations under a multistage production process. By extending the models of Yi (2003, 2010), we derive two distinct features of vertical specialization and test them using Time-Varying Parameter (TVP) VAR. We find that a positive shock to China’s final good consumption increases the intermediate goods trade between Korea and China, with expanding magnitude over time. In addition, the positive effect of a real exchange rate depreciation on intermediate goods trade is strengthened through the competitiveness-enhancing channel, with this effect being more pronouncing in Korea-China trade than in Korea-Japan trade.     

Fair value disclosures and crash risk

In response to the public criticism of the inadequate disclosures mandated by SFAS No. 157, Fair Value Measurements, the FASB issued ASU (Accounting Standards Update) 2010–06, Improving Disclosures about Fair Value Measurements, and ASU 2011–04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements, in an effort to increase the reporting transparency. We examine whether the increased fair value disclosures required by these two updates effectively decrease crash risk, defined as the frequency of extreme negative stock returns. In support of the hypothesis, we find that increased transparency from these updates reduces crash risk among U.S. banking firms and that the reduction is greater in banks that have a higher level of Level 3 financial assets.     

Properties of Census Dual System Population Size Estimators

We study parametric and non‐parametric approaches for assessing the accuracy and coverage of a population census based on dual system surveys. The two parametric approaches being considered are post‐stratification and logistic regression, which have been or will be implemented for the US Census dual system surveys. We show that the parametric model‐based approaches are generally biased unless the model is correctly specified. We then study a local post‐stratification approach based on a non‐parametric kernel estimate of the Census enumeration functions. We illustrate that the non‐parametric approach avoids the risk of model mis‐specification and is consistent under relatively weak conditions. The performances of these estimators are evaluated numerically via simulation studies and an empirical analysis based on the 2000 US Census post‐enumeration survey data.     

Female participation in African labor markets: The role of information and communication technologies

This article investigates the effects of information and communication technologies (ICT) on female labor force participation in a sample of 48 African countries. We specify and estimate linear regression and dynamic panel data models with fixed effects (FE) and system-generalized method of moments (SYS-GMM) estimation over the period 2001–2017. The three main results are that ICT use (mobile phone and internet) significantly stimulates female labor force participation in Africa; this effect is enhanced by financial development and female education; the effect of ICT on female employment in Africa is strongest in the industrial sector. These results remain robust to the provision of social, cultural, and institutional variables.
