中国西南地区面向东南亚的区域专业化分工与合作研究

全球化的发展加强了各国间的经济联系,促进了国际区域间的专业化分工与合作。文章认为,中国西南地区与东南亚各国间的经济联系伴随中国——东盟贸易自由区的建成而更加紧密。中国西南地区与东南亚之间在区域差异的基础上,基于外部竞争压力与内部发展诉求,会在现有有利合作条件下,形成有利于双方的区域专业化分工与合作格局。     

Progress and the economy of nature

Progress is a difficult concept, but the phenomenon itself seems to be more than just an illusion. In this paper we consider how a bioeconomic perspective can help to clarify matters, especially when we compare aspects of organic evolution to technological progress. Beginning with the influence of Malthus upon Darwin, we see how the latter's ideas differ in important respects from those of other biologists and from those of social scientists and philosophers. Consideration of biologist's views about competition and the reasons for specialization suggests ways in which matters might be clarified by a more 'entrepreneurial' view of the relationships of organisms to the natural economy.     

经济转型期多元化经营的风险及对策

多元化还是专业化,这是企业发展过程中常遇到的问题,也是企业最困惑的问题之一。一般地,当宏观经济处于增长期,则行业发展趋好,行业竞争较弱,此时多元化经营比较容易成功;当宏观经济处于成熟期和衰退期,则行业发展趋势变坏,行业竞争加剧,多元化经营则难以成功。经济转型将使传统行业的发展趋势受到不利影响,从而加大多元化经营的风险。     

中国电信行业互联互通问题的博弈分析

在分析我国电信行业互联互通现状的基础上,引入一个双寡头动态博弈模型,说明在垂直一体化的经营模式下,网络规模不对等的电信运营商之间实现互联互通是激励不相容的,由此提出相应的政策建议。     

知识溢出与区域经济增长的关系研究综述

在知识溢出与区域经济增长的关系上，存在MAR溢出、雅各布斯溢出、波特溢出三种不同的观点。MAR假说偏爱低竞争与产业专业化；波特也偏爱专业化，但赞成高竞争；而雅各布斯赞同高竞争与产业多样化。这三种假说都得到了实证经验的支持，结论差异的原因在于使用的方法、样本的时间和变量选取、研究的国家或地区的特征与产业不同。     

比较优势与加工贸易——基于中国各省市的实证分析

受经济全球化的影响，国际分工进一步深化，从产品层面延伸到了产品内不同工序层面，传统的比较优势理论可以解释这种新型产品内分工产生的原因及影响。作为产品内分工的表现形式——加工贸易目前已成为中国最主要的贸易方式。以2000—2005年中国各省市加工贸易进出口额为样本，利用Egger（2005）的方法对加工贸易的影响因素进行定量分析，进而得出比较优势仍是加工贸易的重要决定因素。     

浅析粮食立筒仓粉尘爆炸及防爆措施

Earnings quality: Some evidence on the role of auditor tenure and auditors’ industry expertise

Prior studies suggest that auditors with short tenure are associated with lower earnings quality because of the lack of client-specific knowledge and/or low balling. In this study, we examine whether industry specialization of auditors and low balling affect the association between auditor tenure and earnings quality. We find that the association between shorter auditor tenure and lower earnings quality is weaker for firms audited by industry specialists compared to non-specialists. In addition, we do not find results consistent with the low balling explanation.     

青西油田固井专业化管理模式

针对青西油田参与固井施工的乙方服务公司数量多、甲方管理对象多、管理效率低的问题,提出了固井专业化服务的管理模式及组建专业化服务机构的构想。实践证明,青西油田推行固井专业化服务管理模式是成功的,降低了管理成本,提高了管理效率。对保证固井质量,提高固井效率也产生了积极的作用,取得了较好的效果。     

STRATEGIC VERTICAL INTEGRATION WITHOUT FORECLOSURE*

We determine the endogenous degree of vertical integration in a model of successive oligopoly that captures both efficiency gains and strategic effects. Foreclosure effects are purposely left aside. The profitability of integration originates in the greater ability of integrated firms to adopt a specific type of technologies. We show that vertical merger waves can stop by themselves before integration is complete because of strategic substitutability in vertical integration. This is in contrast to the strategic complementarity result in McLaren [2000] that leads to either complete integration or complete separation.
