基于胜任力结构的企业家才能分析

一、企业家才能的相关理论在西方经济学界,人们认为劳动、资本、土地、企业家才能四部分构成了生产要素,在这四种生产要素中企业家才能则是其灵魂性的要素。企业家才能是指企业领导的经营管理和创新能力,包括创新能力、合作精神、敬业精神、竞争意识、冒险精神、自信、判断能力     

CRIME AND POVERTY: A SEARCH‐THEORETIC APPROACH*

Numerous studies document that criminal activity is positively related to unemployment and negatively related to educational attainment levels within given communities. We study this phenomenon in the context of a search‐equilibrium model, in which agents choose between formal employment and pursuing crime‐related activities (theft). Prior to their “occupational choices,” agents undertake costly schooling, raising their productivity. Crime acts, in essence, as a tax on human capital by affecting the probability that a worker's earnings (possessions) are subsequently appropriated. There are multiple equilibria. High crime, low levels of educational attainment, long spells of unemployment, and poverty are correlated across them.     

The Contingent Value of Responsive and Proactive Market Orientations for New Product Program Performance*

While the benefits of being market oriented are largely accepted, a group of scholars and managers remain skeptical. Marketing scholars have sought to counter the criticisms leveled against market orientation (MO) by arguing that it has both responsive and proactive dimensions. However, few studies have empirically examined the complexity of the effects of these dimensions on firm performance. Drawing on theories of resource‐based advantage and organizational search behavior, this article advances understanding by arguing that responsive and proactive market orientations have curvilinear effects on product development performance, that their interaction may be positively related to product development performance, and that their effects on new product program performance are moderated differentially by the organizational implementation conditions and marketing function power. Survey results of 175 U.S. firms indicate support for most of the hypotheses. Specifically, whereas responsive MO has a U‐shaped relationship with new product program performance, proactive MO has an inverted U‐shaped relationship with new product program performance. Contrary to the arguments presented here, the interaction of both orientations is negatively related to new product program performance. This study finds that both orientations are needed; however, new product program performance is enhanced when one is at higher level and the other is at lower level. Finally, responsive MO is only positively related to new product program performance under specific conditions such as when strategic consensus among managers is high. On the other hand, the positive effect of proactive MO on new product program performance is further strengthened when learning orientation and marketing power are high. Overall, this study suggests that the effects of responsive and proactive MO on new product program performance are more complex than previously theoretically argued and empirically examined.     

Feature selection methods involving support vector machines for prediction of insolvency in non‐life insurance companies

We propose two novel approaches for feature selection and ranking tasks based on simulated annealing (SA) and Walsh analysis, which use a support vector machine as an underlying classifier. These approaches are inspired by one of the key problems in the insurance sector: predicting the insolvency of a non‐life insurance company. This prediction is based on accounting ratios, which measure the health of the companies. The approaches proposed provide a set of ratios (the SA approach) and a ranking of the ratios (the Walsh analysis ranking) that would allow a decision about the financial state of each company studied. The proposed feature selection methods are applied to the prediction the insolvency of several Spanish non‐life insurance companies, yielding state‐of‐the‐art results in the tests performed.

Artificial neural networks with feature transformation based on domain knowledge for the prediction of stock index futures

A feature transformation method based on domain knowledge for arti?cial neural networks (ANNs) is proposed. The method of feature transformation based on domain knowledge converts continuous values into discrete values in accordance with the knowledge of experts in speci?c application domains. This approach effectively ?lters data, trains the classi?er, and extracts the rules from the classi?er. In addition, it reduces the dimensionality of the feature space, which not only decreases the cost and time in the operation but also enhances the generalizability of the classi?er. The experimental results of the proposed approach will be compared and tested statistically with the results of the linear transformation method. The results show that the method of feature transformation based on domain knowledge outperforms the linear transformation in modelling of ANNs. Copyright © 2004 John Wiley & Sons, Ltd.     

调整政府支出结构 促进居民消费增长——基于政府支出与居民消费互补性关系的分析

本文主要从政府支出与居民消费的互补性关系出发,提出政府支出结构调整的三个主要方面,即加大农村基础设施的投资、加大教育和健康服务等优效品的支付以及加大社会保障和收入支持的支出,以此促进居民消费快速增长,推动经济增长由主要依靠投资和出口拉动向主要依靠内需特别是消费拉动转变。     

The service sector of Cuba: An analysis and critique

The Cuban economy has experienced a significant increase in foreign direct investment over the past decade due to the end of the Soviet Union and the establishment of more liberal trade policies. Although the U.S. embargo of trade with Cuba still exists, there has been movement lately that suggests the end of the four‐decades‐old policy. The purpose of this article is to analyze the current Cuban business environment and to identify potential entrepreneurial opportunities in the service sector. Major trade partners are also reviewed and managerial implications discussed. © 2006 Wiley Periodicals, Inc.     

循环经济的资金循环障碍及其对策分析

本文基于我国国情分析了循环经济实施的资金循环障碍,提出解决路径,并分析对经济发展的影响。低价甚至无价使用资源环境,不仅导致资源快速耗竭和生态环境恶化,而且客观上阻碍了知识经济的发展。实施刺激循环经济的积极财政政策,不仅对缓和资源消耗过快和环境问题是必要的,而且对促进产业结构调整,扩大就业,增强企业国际竞争力等当前我国经济面临的紧迫问题的解决有积极意义。     

引进战略投资者的谋略

一、正确界定战略投资者 战略投资者是指与标的企业业务联系紧密、以谋求长期战略利益为目的、持股量较大且长期持有、拥有促进标的企业业务发展的实力并积极参与公司治理的法人投资者.与一般法人投资者相比,战略投资者持股的安定性更强、集中度更高、参与公司治理的积极性更大,因而是一种积极持股者和安定性股东.     

集团公司现金回收管理系统的建立与控制

中国经过20多年改革开放的风雨历程，正在进入竞争日趋激烈的世界大市场，融入国际经济大循环。在现代企业制度相继建立后，要在竞争中取胜，必须彻底转变在计划经济体制下的行政性、经验性、粗放型的管理模式，使之向市场化、知识化、集约化的方向发展，实现经营管理的现代化。随着科学技术不断进步，市场竞争日益激烈，生产经营日趋复杂，企业规模不断扩大，跨地区、跨行业经营的集团公司不断涌现，这就对集团公司的管理提出了较高的要求。本文只探讨集团公司的现金回收管理问题。
