中国居民收入分配差距扩大现状、原因与对策

深化分配制度改革,缩小收入差距,实现真正的共同富裕是实现中国经济可持续发展的重要问题之一.改革开放以来我国经济社会发展的现实说明居民收入差距有不断扩大的趋势.既有受教育程度、技能水平、就业机会的不均等,也有经济结构变化、经济政策变化、市场机制等方面的原因.在此基础上,提出了缩小收入差距,实现共同富裕的具体对策是:发展教育和经济,扩大就业;坚持就业优先和兼顾公平相结合的分配原则;切实增加农民收入;规范市场竞争秩序,强化收入分配制度改革,完善最低工资保障制度等.     

对缩小收入差距问题的远近期思考

国际上通常使用基尼系数作为衡量一个国家或地区收入差距的重要标志。我国居民收入基尼系数不仅高于国际通行标准，也高于发达国家。收入差距扩大已经成为影响消费规模扩大、社会安定的重要因素之一。一般认为，经济发展会进一步扩大收入差距。治理并缩小收入差距应标本兼治：短期内可以依靠收入转移、完善社会保障系统等手段；从长期看，深化经济体制改革、促进经济健康稳定发展才是缩小乃至逐步消除收入差距的根本途径。     

我国居民收入分配差距扩大问题研究

我国居民收入分配差距的产生和扩大,是旧的制度体系局部沉淀及新的制度体系尚未完善的制度变迁的一个结果.对过大差距的调节,包括对不合理差距的治理,应从制度创新与完善、发挥市场、政府及第三种力量的调节作用等方面多做工作.     

基于久期缺口的商业银行利率风险免疫策略及实证分析

随着利率市场化的深入，利率风险越来越成为影响商业银行绩效的主要风险，因此，如何对商业银行利率风险进行计量及管理，日益成为国内外学术界高度关注的重要课题。通过建立久期缺口模型，提出了商业银行利率风险免疫策略，并进行实证分析表明：通过确立目标项目，调整资产与负债结构，可以较好地实现商业银行的利率风险免疫。     

商业银行控制利率风险的技术和工具

随着我国利率市场化改革进程的加快以及我国与世界经济和金融联系的加强 ,利率波动的频率和幅度将越来越大 ,因而商业银行将面临更大的利率风险。为此 ,本文介绍了西方商业银行如何运用持续期缺口、远期利率协议、期货、期权等技术和工具来管理和控制利率风险 ,以期对我国的商业银行有所借鉴。     

航空燃油市场的发展趋势

国际航空燃油市场虽然持续供于求，但是中国持续出现需求缺口，我们调研了中国国内航空燃油生产商和分销机构等，采用规范和实证的分析方法，提出了一些重要结论：中国航空燃油生产和供给成本高，资源配置效率有待进一步提高，航空燃油需求继续旺盛，新世纪里的十年几需求缺口可能进一步扩大。     

中国农村金融发展对城乡收入差距的影响--基于1978-2004年数据的检验

大多数研究表明,改革开放以来,中国整体金融发展显著扩大了城乡收入差距,同时,它们从城乡金融发展不平衡角度进行了理论阐释。本文则从农村自身经济发展层面出发运用1978-2004年的相关数据分析了农村金融发展与城乡收入差距之间的关系,结果显示:农村金融发展扩大了城乡收入差距,究其原因主要是农村资金的不断外流和非正规金融的不规范发展,加剧了城乡收入差距的扩大。现实的出路是遏制农村资金外流,提供更多的农村正规金融资源;规范非正规金融发展,防范农村金融风险。     

英国的非公开权益资本和风险投资

英国是欧洲风险投资和非公开权益资本的发源地。在欧洲国家中,英国的风险投资和非公开权益资本起步最早,发展也最快。从1979年算起,英国风险资本投资额和非公开权益资本增长了100多倍。2005年,在欧洲的风险投资市场上,英国的风险资本总额占欧洲风险投资额的40￣50%,在欧洲是当仁不让的“大哥大”,在世界范围内仅次于美国。本篇文章主要介绍了风险投资(VentureCapital,VC)及非公开权益资本(PrivateEquity,PE)的最新概念和从属关系以及英国的风险投资及非公开权益资本的历史、结构、规模、投资趋势、投资阶段、投资领域、地理特征、知名风险企业、投资表现等,以此从数据和分析的角度使中国的风险投资领域及非公开权益资本领域的从业人员以借鉴、启迪的作用。     

Evidence on the efficacy of interest-rate risk disclosures by commercial banks

This paper documents evidence on the efficacy of maturity-gap disclosures of commercial banks in indicating their net interest income that is exposed to interest-rate risk. For the large sample of banks that filed call reports from 1990 to 1997, a period that includes a wide range of interest rate movements, we find that (i) one-year maturity gap measures are significantly related to the one-year- and three-years-ahead change in net interest income, (ii) fixed-rate and variable-rate instruments differ in explanatory ability, and (iii) the one-to-five-year aggregate gap measures also have some power in explaining three-year-ahead changes in net interest income. These findings hold after controlling for the ex post growth in assets as well as the amount of rate-sensitive assets and liabilities (a competing set of explanatory variables). Because the Securities and Exchange Commission (SEC)'s [Securities and Exchange Commission (SEC), (1997). Disclosure of accounting policies for derivative financial instruments and derivative commodity instruments and disclosure of qualitative and quantitative information about market risk inherent in derivative financial instruments, other financial instruments, and derivative commodity instruments. Release Nos. 33-7386; 3438223; IC-22487; FR-48; International Series No. 1047; File No. S7-35-95 (January 31, 1997), Washington, DC] tabular disclosures are finer than maturity-gap data, our findings mitigate concerns about the usefulness of the SEC's market-risk-disclosure requirements. Furthermore, they suggest contrary to the claims of certain banks that the omission of prepayment and early withdrawal risk from gap measures does not totally compromise the ability of gap data to indicate interest-risk exposures.     

The impact of population growth and climate change on food security in Africa: looking ahead to 2050

Providing nutritious and environmentally sustainable food to all people at all times is one of the greatest challenges currently facing society. This problem is particularly acute in Africa where an estimated one in four people still lack adequate food to sustain an active and healthy life. In this study, we consider the potential impact of future population growth and climate change on food security in Africa, looking ahead to 2050. A modelling framework termed FEEDME (Food Estimation and Export for Diet and Malnutrition Evaluation) was used which was characterized to model the impacts of future climate changes (utilizing the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios projections) and projected population growth on food availability and subsequent undernourishment prevalence in 44 African countries. Our results indicate that projected rapid population growth will be the leading cause of food insecurity and widespread undernourishment across Africa. Very little to no difference in undernourishment projections were found when we examined future scenarios with and without the effects of climate change, suggesting population growth is the dominant driver of change. Various adaptation options are discussed, such as closing the yield gap via sustainable intensification and increasing imports through trade and aid agreements. These strategies are likely to be critical in preventing catastrophic future food insecurity.
