产品语言创新解释性维度的推进机制研究

在全球化竞争环境下,本土化战略的实施可以采取一种基于社会文化模式变迁的产品语言创新方式,其成功与否取决于对社会文化模式变迁的解释力以及这种解释性维度向企业内部的有效推进。分析了产品语言创新解释性维度的推进过程、障碍及解决机制。研究表明,推进过程的关键环节依次为项目接口、组织边界接口和创意-创新接口;各接口处的障碍分别为高层管理者的认知僵化、企业内部解释者固定或者信念和认知被强化、组织信念和组织常规;解决途径分别为提高管理者的学习能力、增强个人忘记、建立独立的对话空间、加强沟通,以及与新组织的合作。     

Purification, saturation and the exact law of large numbers

Purification results are important in game theory and statistical decision theory. We prove a new purification theorem that generalizes several earlier results. The key idea of our proof is to make use of the exact law of large numbers. As an application, we show that every mixed strategy in games with finite players, general action spaces and diffused, conditionally independent incomplete information has many strong purifications.     

避专利工艺与海正药业的技术能力升级

以企业技术能力升级的相关理论为基础,采用海正药业的3个他汀类产品为案例分析对象,对海正药业他汀类产品在应用“避专利工艺”过程中所采取的做法和获得的收益进行了分析与总结。研究发现,通过采取“避专利工艺”,海正药业获得的不仅仅是产品上的收益,更重要的是提高了企业的技术能力,尤其是国内药企普遍缺乏的创新能力。     

创业者经验对创业机会识别影响模型构建

基于现有创业经验学习研究文献,清晰地界定了创业机会识别、创业者经验、创业学习和创业自我效能的概念,划分其维度,深入探讨了创业者经验对创业机会识别的作用机制,提出相关理论命题,构建了创业者经验-创业学习、创业自我效能-创业机会识别理论模型,为创业者经验实证研究奠定了必要的理论基础。在此基础上,指出研究局限,并对未来创业者经验研究方向进行了展望。     

中国交通基础设施建设改善了企业资源配置效率吗?——基于高速公路建设与制造业企业要素投入的分析

交通基础设施建设已被证实是改善发展中国家经济表现的重要因素,但其中的作用机制仍然众说纷纭.近年来,人们普遍认为资源在企业间的配置效率不同是国家间经济绩效差异的重要原因.为了验证交通基础设施是否确实影响了企业资源配置效率,进而提升了经济绩效,文章将中国制造业企业数据与高速公路建设数据进行匹配,并以此为基础对中国交通基础设施建设对企业资源配置效率的影响及其作用机制进行了实证分析.我们的研究发现:交通基础设施建设确实改善了企业的资源配置效率,距离高速公路更近的城市,企业的实际规模与最优规模差异更小.具体来看,交通基础设施降低了同时使得资本和劳动投入偏离的产出扭曲,使得企业的实际规模与最优规模更为接近.进一步的中介效应分析发现,高速公路影响企业资源配置效率的因素主要有价格加成和行业集中度等,而通过企业存货产生的作用并不显著.     

中国贸易含碳量及其影响因素--基于(进口)非竞争型投入产出表的分析

本文基于(进口)非竞争型投入产出表估算了1987-2007年中国的贸易含碳量及其部门分布和国别(地区)流向,并通过结构分解分析了六大因素对其变化的影响.结果表明,2005年以来中国已经成为碳的净输出国.贸易含碳量的迅速增加主要是由贸易规模的增长带来的,不断降低的部门能源强度则是抑制其增加的主要因素,而进出口产品结构、投入结构、能源结构及碳排放系数的变化对其影响较小.     

浙江传统文化与企业家阶层形成研究

什么是文化?哈耶克认为,文化乃是一种由习得的行为规则构成的传统,这种规则可能起始于人类所拥有的不同的环境情势下知道做什么或不做什么的能力。文化的经济学界定是：文化是指人民所习得的与遵从的特定价值观体系,它构成了人们的主观模型,人们无论是进行生产、交换、还是分配、消费活动,总是需要一个特定的价值观体系来帮助判断决策。文化的内容包括最基本的价值信念、伦理规范、道德观     

Stock return reversal and continuance anomaly: new evidence from Hong Kong

Using weekly data, this article conducts a comprehensive analysis and presents new empirical evidences on the short-term stock return reversal and continuance anomaly in the Hong Kong stock market. We confirm that winner stocks behave differently from loser stocks in that the return reversal phenomenon is pervasive within past winner stocks only while past loser stocks tend to show weak return continuance. The arbitrage strategy can earn significantly positive contrarian profits, especially for small firms and illiquid stocks. The anomaly varies across different industries and is also sensitive to the market movement. Despite the existence of the anomaly, our results still in general suggest that the Hong Kong stock market is weak-form efficient because arbitrage trading costs would largely overwhelm the available profits in most cases.     

An analysis of irrigated agricultural outcomes under the prior appropriation doctrine: hypotheses and applications

This article measures irrigated agricultural outcomes under the prior appropriation doctrine by developing a model of farmers’ land allocations in response to water supply change. The modelling approach considers the institutional factors of water rights and permits the inclusive determination of water and land allocations. We utilize farm-level data of irrigated agriculture in Water District #1 in Idaho to examine the predictions from our theoretical model. The water rights priority date is consolidated at the farm level and used to differentiate farmers’ responses. We test a set of hypotheses that relate to water supply and crop revenue. Our results suggest that the water rights priority has a profound impact on agricultural outcomes, indicating strong institutional effects and weak influence of market-based approaches. Farmers respond to both long-term and seasonal water supply change and variation, and they respond to seasonal water supply forecasts in varied ways depending on their water rights portfolios, thus signalling a disproportionate distribution of potential impacts of water supply change.
