On the robustness of the competitive equilibrium: Utility-improvements and equilibrium points

We show that the set of competitive equilibrium points of a pure exchange economy are the equilibrium points of a broader class of better-response demands than the usual utility-maximizing demand functions. The better-response demands are derived from assigning weights to all commodity bundles with higher utility than the current commodity bundle, with the greatest weights being placed on the commodity bundles with the highest utility gain. The usual utility-maximizing demand functions are then those in which the weight on the utility-maximizing bundle is one. We also show that these better-response demands belong to a large class of response maps that are generated by monotonic transformations of the utility functions and/or monotonic transformations of the weights assigned to the commodity bundles.     

Creating competitive advantage: Linking perspectives of organization learning,innovation behavior and intellectual capital

Drawing on learning theories and the intellectual capital (IC) theory, organizational learning research has discussed the benefits of searching for market opportunities and maintaining a competitive advantage in dynamic environments. To explain organizational performance and survival, the previous literature has focused mainly on what organizations do, but it has failed to address how and what they should do. This study argues that if hotel management is open-minded about exploratory and exploitative learning, it can open the door to capturing opportunity and competitive advantage through increased innovation behavior and human capital accumulation. Further, IC theory has also confirmed that social capital and relational capital will strengthen the relationship between innovation behavior and human capital. This study analyzes data from 595 hotel managers and finds strong support for the proposed hypotheses.

中国卷烟行业竞争态势分析

我国卷烟企业长期存在生产规模小、分布范围散、销售区域性强等的特点,卷烟行业始终处于一种"优不胜、劣不汰"的低水平均衡。本文从博弈的角度解释了这种现象的产生原因,并分析了我国卷烟行业的市场竞争类型,提出建立寡头垄断市场是重组卷烟企业的目标。     

电子信息产业国内价值链省域比较优势测度及空间差异研究

为应对后疫情时代全球电子信息产业加剧的“比较优势陷阱”,中国亟需通过国内价值链省域比较优势的互补协同提升整体国际竞争力。在价值链产品内,基于垂直专业化分工框架,兼顾增值能力与劳动生产率两个维度,使用非竞争型投入占用产出模型,设计一个评测国家内部区域电子信息产业真实比较优势的新指标。结果表明,东部沿海省域比较优势强度与广度最为显著,内陆省域比较优势集中于上游能源型部门;制造业部门比较优势凸显,服务业部门比较优势相对薄弱;比较优势高省域集中度与低省域集中度的产业部门中,均存在整体比较优势强弱差异,其中,高省域集中度产业部门比较优势强度更高。     

竞争战略演化技术创新的影响——以江苏民营制造企业为例

基于江苏民营制造企业的问卷调查数据,在控制了地区和产业类别影响前提下,探讨同一情境下处于生命周期不同阶段企业取得竞争优势的竞争战略所构成的演化路径,并从技术创新视角揭示竞争战略演化的动因。研究表明,处于初创期、成长期、成熟期的企业,竞争战略呈现＂没有明确选择-低成本战略-差异化战略＂的演化路径。工艺创新对低成本战略演化有显著影响,产品创新对差异化战略演化有显著影响。总体上看,工艺创新是企业竞争战略演化的主要推动力。推进制造企业转型升级,需要加大产品创新力度,提升产品创新对竞争战略的影响。     

分析师的盈利预测偏差与本地优势

分析师在金融市场中起着重要的信息中介作用,其信息来源及获取方式会直接影响信息处理的质量。本文从分析师对企业年度盈利预测的偏差出发,基于对分析师与公司地域关系的实证研究,发现分析师在预测那些所在地与分析师隶属的机构同属一个省份的公司时,预测结果更加准确,这种本地优势与公司高成长性及公司国有性质显著相关。研究还发现,我国分析师的本地优势与个人本身的乐观性并无关系,可能更多与信息优势相关。     

Corporate foresight: Its three roles in enhancing the innovation capacity of a firm

In the last three decades much knowledge has been produced on how best to conduct foresight exercises, but little is known on how foresight should be integrated with the innovation effort of a company. Drawing on empirical evidence from 19 case studies and 107 interviews, we identify three roles that corporate foresight should play to maximize the innovation capacity of a firm: (1) the strategist role, which explores new business fields; (2) the initiator role, which increases the number of innovation concepts and ideas; and (3) the opponent role, which challenges innovation projects to increase the quality of their output.     

Technology competencies in competitive environment

Although prior studies suggest that technology competencies play a significant role in firm innovation and competitiveness, what and how technology competencies interacted with competitive environment affect firm innovation has not been fully understood. This paper fills this research gap through a questionnaire survey of 165 firms together with a number of interviews drawn from the Taiwan's information and communication technology (ICT) industry. The results suggest that capabilities of exploring or exploiting technological opportunities, core technology capability, and autonomy of R&D decisions are particularly important to firm innovation in a highly competitive environment, whereas over commitments to existing technologies may constrain a firm's innovation especially in such environment. Moreover, different types of competitive environment require different types of technological competencies to enhance firm innovativeness. This paper contributes to the existing theory by examining the joint effect of technology competency and competitive environment on a firm's innovation.     

以期货市场为突破口推进大连区域性金融中心建设

从地区发展构想以及区域经济发展的角度,中国内地许多中心城市都提出了建设区域性金融中心的设想,进而涌现出了建设区域性金融中心的热潮。环渤海地区的大连、天津、沈阳等城市都确定了建设金融中心的发展战略。三个城市各自拥有自己的优势与不足,应扬长避短,错位发展。大连应充分利用大连商品交易所这一独特的金融资源,以期货业为龙头,带动相关机构和市场资源的聚集。
