中国上市公司债权对公司绩效影响的实证研究

关于债权的治理效应，代理成本理论和控制权理论都认为，企业资本结构中一定的负债有利于公司治理效率的提高。本文以2002～2004年度沪市上市公司为样本（样本总量为2284组数据），对我国上市公司的债权治理效率进行了实证分析。结果表明，我国上市公司负债对其绩效有重要影响：债权比例与公司绩效在统计上呈显著的负相关关系，即上市公司的负债比例越大，其绩效也会越差，公司绩效与负债还存在着显著的二次关系，当资产负债率（DAR）为21．79％时，若其他条件不变时，债权对公司绩效促进作用最大，超过这一比例，债权与公司绩效呈负相关。本文对这一结果进行了原因分析，并提出了政策建议。

人力资本、财务资本与资本结构：理论和实证

当今社会已经从工业经济迈进知识经济时代，现有以财务资本为研究对象的资本结构理论在解释咨询、高新技术等人力资本较为密集的公司时难免会捉襟见肘。视企业为财务资本与人力资本共同的投资组合是现代资本结构理论研究刻不容缓的任务。本文以现有财务资本结构的研究为基础，通过引入人力资本变量拓宽现代资本结构的内涵，构造债务、股权和人力资本三者之间相互关系和作用的数理模型，结合对我国计算机应用服务业的实证分析，得出结论和启示。     

Total factor productivity and R&D capital in the spanish economy, 1965–1980

A formal model of productivity growth and technical progress is presented. The model takes into account embodied and disembodied technical progress as explanatory variables. The slowdown in productivity growth for the Spanish economy after 1972 is explained for 92% by the decline in the rate of growth of technical progress originated from domestic R&D and technology imports.

The living company

What can explain the longevity gap between a company that survives for centuries--the Swedish company Stora, for example, which is more than 700 years old--and the average corporation, which does not last 20 years? A team at Royal Dutch/Shell Group explored that question. Arie de Geus, a retired Shell executive, writes about the team's findings and describes what he calls living companies-organizations that have beaten the high mortality rate of the average corporation. Many companies die young, de Geus argues, because their policies and practices are based too heavily on the thinking and language of economics. Their managers focus on producing goods and services and forget that the organization is a community of human beings that is in business--any business--to stay alive. In contrast, managers of living companies consider themselves to be stewards of a long-standing enterprise. Their priorities reflect their commitment to the organization's long-term survival in an unpredictable world. Like careful gardeners, they encourage growth and renewal without endangering the plant they are tending. They value profits the same way most people value oxygen: as necessary for life but not the purpose of it. They scuttle assets when necessary to make a dramatic change in the business portfolio. And they constantly search for new ideas. These managers also focus on developing people. They create opportunities for employees to learn from one another. Such organizations are suited for survival in a world in which success depends on the ability to learn, to adapt, and to evolve.     

"突破菏泽"经济发展模式的几点思考

菏泽市，古称曹州。历史上，菏泽因水而穷。建国前，黄河三年两决口，菏泽人民饱受自然灾害之苦，生产条件恶劣，工业几乎空白。建国后到改革开放前，菏泽处于吃粮靠统销、生产靠贷款、生活靠救济的“三靠”状态。长期恶劣的生存环境使不少菏泽百姓逐渐形成了不敢积累、不愿意积累、无意识积累的生活习惯。从1992年到2002年的10年间，菏泽市GDP年均增长6．8％，比全省平均水平低6个百分点，菏泽市累计实际利用外资仅占全省累计实际利用外资的1％，累计出口总值仅占全省累计出口总值的0．5％。2003年菏泽市人均GDP3337元，仅为全省平均水平的25％。1992年菏泽GDP同德州、聊城、滨州经济实力大体相当，现在差距却越来越大，从这些数字中折射出一个严峻的现实：菏泽何去何从？     

试析保险欺诈

保险欺诈是保险公司面临的一项难题。保险欺诈的形式有订立保险合同时的欺诈和保险索赔时的欺诈。保险欺诈的产生有其本质根源、社会根源、心理根源和保险业的内部根源。寻找有效的防范保险欺诈的方法需要从加大保险宣传、充分利用法律武器及提高保险公司的承保和理赔管理水平各方面入手。

Credit Risk in Two Institutional Regimes: Spanish Commercial and Savings Banks

Although credit risk is an important factor that financial institutions must cope with, the determinants of bank problem loans have been little studied. Using panel data, we compare the determinants of problem loans of Spanish commercial and savings banks in the period 1985–1997, taking into account both macroeconomic and individual bank level variables. The GDP growth rate, firms, and family indebtedness, rapid past credit or branch expansion, inefficiency, portfolio composition, size, net interest margin, capital ratio, and market power are variables that explain credit risk. However, there are significant differences between commercial and savings banks, which confirm the relevance of the institutional form in the management of credit risk. Our findings raise important bank supervisory policy issues: the use of bank level variables as early warning indicators, the advantages of bank mergers from different regions, and the role of banking competition and ownership in determining credit risk.
