沈阳市会展旅游的战略选择

沈阳市作为东北的区域中心城市和历史文化名城，会展旅游现状与其在全国的地位不相符。沈阳市只有明确会展旅游定位、借鉴会展旅游发达城市经验、发挥政府功能和作用、建立会展旅游企业集团、培养会展旅游专业人才，才能提高沈阳市的会展旅游地位与影响。     

高技术产业中排他性合约研究——以英特尔和AMD为例

构建上游双寡头和下游多家厂商的排他性交易模型。以上游优势厂商控制的下游厂商数量为决策变量,分析了在位上游优势厂商通过控制下游厂商,导致中间产品的价格歧视,剥削下游厂商,排挤竞争对手,提高最终产品价格和不利于产业良性竞争等负面影响。     

外部环境、资源拼凑与“军技民用”新产品开发关系研究

基于资源拼凑理论视角,运用扎根理论对传统军工企业“军技民用”新产品开发过程进行探究,并探索外部环境、资源拼凑对“军技民用”新产品开发的作用机理。结果发现：“军技民用”新产品开发包括信息获取、技术选择、技术再造3个过程;资源拼凑是“军技民用”新产品开发的有效措施;外部环境对资源拼凑开发“军技民用”新产品过程具有调节作用。     

Competitive search markets for durable goods

Summary. This paper considers a dynamic version of Akerlof's (1970) lemons problem where buyers and sellers must engage in search to find a trading partner. We show that if goods are durable, the market itself may provide a natural sorting mechanism. In equilibrium, high-quality goods sell at a higher price than low-quality goods but also circulate longer. This accords with the common wisdom that sellers who want to sell fast may have to accept a lower price. We then compare the equilibrium outcomes under private information with those under complete information. Surprisingly, we find that for a large range of parameter values the quilibrium outcomes under the two information regimes coincide, despite the fact that circulation time is used to achieve separation.

中国经济发展的投入产出效率研究

从投入产出角度,运用超效率三阶段DEA模型与Malmquist模型相结合的分析方法,修正了环境因素与随机因素的影响,从静态与动态的时间角度对2008_2012年我国30个省（市、自治区）经济发展效率进行分析。结果表明：从静态层面看,我国各省经济发展效率不容乐观,综合效率值较低,大约2/3省的经济发展都处于低效状态;经济发展效率受环境影响较大,剔除环境因素的影响后,各省综合效率均显著下降;三大区域中,东部地区经济发展效率仍处于领先地位,西部地区次之,中部地区最低,但整体来看区域间经济发展效率差异逐渐减小。从动态层面看,通过Malmquist模型分析,考察期间全要素效率和综合技术效率M值逐年下降,技术进步效率逐渐增长,且全要素效率下降的主要原因是纯技术效率下降。因此,各地区应该充分发挥优势,加快技术创新,提高规模效率,进一步提升发展水平。     

Rationalizability and equilibrium in N-person sequential bargaining

Summary. This paper deals with N-person sequential bargaining games with complete information. For N-person sequential bargaining games, uniqueness of the SPE has been obtained by allowing the players to exit with partial agreements. Adopting a non-equilibrium approach, we show that N-person sequential bargaining games with exit are solvable by a refinement of rationalizability for multi-stage games (trembling-hand rationalizability) whatever the impatience of the players. That is, once we adopt the non-equilibrium approach, the exit opportunity still fulfils its original aim: we achieve a unique solution by introducing the exit opportunity. Moreover, this unique solution is the unique SPE. Received: October 30, 1996; revised version: July 7, 1998     

A cognition paradigm clash: Simon,situated cognition and the interpretation of bounded rationality

Simon’s notion of bounded rationality is deeply intertwined with his activity as a cognitive psychologist and founder of so-called cognitivism, a mainstream approach in cognitive psychology until the 1980s. Cognitivism, understood as ‘symbolic information processing,’ provided the first cognitive psychology foundation to bounded rationality. Has bounded rationality since then fully followed the development of cognitive psychology beyond symbolic information processing in the post-Simonian era? To answer this question, this paper focuses on Simon’s opposition during the 1990s to a new (paradigmatic) view of cognition called situated cognition, which has since put into question the entire view in cognitive psychology of humans as symbolic information processors. This paper then reads the cognitivism/situated cognition debate through the lens of current bounded rationality research in economics, in order (i) to inquire into whether it has tackled the issues in that controversy; (ii) to envisage possible new foundations for a cognitive psychology-based bounded rationality.     

高校教师个性含义、意义及实现

教师个性是教师专业个性与教师自身个性的统一,由教育风格表现出来,是教师存在的方式。个性的教师才是完整的教师,才是有活力的教师。当代个性教育呼唤教师个性,要求培养个性的高校教师。因此,当前的高校应该强化个性教育观,弘扬教师个性;增强创新教育观,发展高校教师个性的独特性。

基于DEA三阶段的我国财产保险公司经营效率测度研究

研究国内保险公司经营效率的文献多采用DEA二阶段模型,其最大的不足之处是无法剥离环境和误差因素对效率值的影响。本文运用能够调整环境变量与随机干扰等因素的DEA三阶段分析方法,对2009年我国财险业的46家公司的经营效率进行分析,结果表明:内外资财险公司的经营效率差距较大,我国大部分财险公司处于规模报酬递增阶段,需适度扩大规模来提升规模效率;纯技术效率处于较低水平,需不断提升公司的管理决策水平。
