Technological forecasting at the Korean stock market: A dynamic competition analysis using Lotka–Volterra model

The purpose of this paper is to attempt to analyze the dynamic relationship between the Korean Stock Exchange (KSE) and Korean Securities Dealers Automated Quotation (KOSDAQ), two competing markets at the Korean stock market, in the viewpoint of technological forecasting of competition. The Lotka–Volterra system of equations, one well-known competitive diffusion models, is adopted to represent the competitive situations of the Korean stock market and it is estimated using daily empirical index data of KSE and KOSDAQ during 1997–2001. The results show that there existed a predator–prey relationships between two markets in which KSE acted as a prey for the time being after the emergence of KOSDAQ. This interaction was altered to symbiotic relationship and finally to pure competition relationship. We also perform an equilibrium analysis of the estimated Lotka–Volterra equations. As a result, we find that there is an equilibrium point in a dynamic sense. However, the equilibrium point could be unstable in the latest pure competition relationship.     

公司治理思想的历史演变及其经验启示

现代企业之间的竞争,也是治理结构的竞争.在此,以文献梳理的形式,对公司治理的内涵及理论渊源进行阐述,并评析了治理模式、形成原因及趋同表现.在我国治理模式选择的问题上,提出应汲取西方治理经验并结合我国国情,在基于利益相关者的原则下,着力构建内部治理与外部治理相结合,以内部治理为主的中国特色公司治理结构.     

干旱区绿洲生态农业现代化模式研究

西北地区是我国典型的干旱区,水资源匮乏、生态脆弱和气候干燥等因素是干旱区的主要特征,在该区农业现代化的进程中这些特点是不容忽视的。文章从农业现代化模式含义的理解入手,通过对国内外先进农业模式的研究,借鉴其在发展过程中的经验与教训,总结出适合西北干旱区绿洲生态农业发展的现代化模式,并将模式定位于滴灌大田精准农业现代化模式、滴灌设施农业模式、滴灌特色林果(药)复合农业模式与现代农业示范园区模式。     

ISO9000标准贸易效应的实证研究

尽管至今已有大量文献研究了国际标准的贸易效应,但我们对实际情况仍然了解甚少。以ISO9000标准为代表对国际质量标准的贸易效应进行了实证研究,研究借鉴了引力模型,将各国ISO9001：2000／2008标准认证企业数量作为贸易条件参数。实证结果表明,出口国和进口国ISO9000标准认证的增加都有利于促进出口增长,这在发展中国家对发达国家的出口中表现的最为明显。这意味着,对我国出口企业而言,ISO9000标准在缓解信息不对称方面的正面作用远远超过了认证成本增加带来的负面影响。     

创新驱动下中国区域高质量发展——基于平衡充分发展水平的门槛分析

创新驱动是破解中国区域不平衡不充分发展的突破口,是实现高质量发展的助推器。采用2003—2017年中国30个省市(因数据缺失,不包括西藏地区和港澳台地区)面板数据,运用全局参比Malmquist模型测度了中国区域高质量发展水平,并通过构建指标体系分别对中国各省市的平衡发展和充分发展水平进行了评价,然后通过门槛回归模型分析了在不同平衡和充分发展水平下创新驱动对于高质量发展的影响机制。结果发现:①区域高质量发展水平呈现出先下降后上升的变化趋势;②各省市平衡和充分发展水平均呈现上升趋势,但各省市之间的变化情况差异较大,有明显的空间集聚特征;③在不同的平衡及充分发展水平下,创新驱动对高质量发展的影响机制是不同的,当平衡充分发展水平较低时,创新驱动对高质量发展没有显著影响;当平衡充分发展达到一定水平时,创新驱动对高质量发展起到一定的促进作用;随着平衡充分发展水平的进一步提高,创新驱动对高质量发展的促进作用越来越大。     

Disruptive Innovation in the Nordic Countries＇ Healthcare Systems

The Nordic healtheare model is recognized to be one of the most innovative in the world. Here billions of USD are annually invested in developing new treatments, drugs, robots etc. to diagnose and cure diseases. Nevertheless, this study establishes that there is a fundamental shortcoming in the system that supports healthcare innovation： It is strongly biased towards micro-level innovation projects focusing on new products, alternative processes, and new financial solutions. The problem with this approach to support new projects is that the results are created as inventions within the system thus lacking holistic perspectives. This has consequently contributed with increasing costs that are out of proportion with existing budgets. Therefore this study seeks to analyze the current understanding of the Nordic healthcare system from a business model perspective. Here other aspects of the healthcare system are explored to determine if they could be redesigned to promote new types of innovation projects. The purpose of undertaking this task is to challenge the established patterns of the current healthcare innovation support practices. Here the vertical innovation process （VIP） framework, which is a systematic radical innovation model that seeks macro-level outcomes based on standalone inventions （see more below）, is applied to analyze the current state-of-the-art in Nordic healthcare innovation projects. The results determine that very little attention is given to rethink and redesign the healthcare system at a macro-level, and it is discussed that stand-alone inventions ought to be rethought into the entire healthcare system to create a larger impact. Finally, it is argued that existing performance measures are inappropriate to foster projects that innovate the existing system： New measuring points should be developed to promote macro-level projects and to avoid the current rapid increase of costs in the Nordic healthcare system.     

人力资本培养与经济增长:来自中国的证据检验

利用1952～2009年时间序列数据,实证分析了中国人力资本培养与经济增长之间的关系。根据单位根检验、协整检验以及VAR模型估计等经验分析,结果发现,中国经济增长与人力资本培养各自的独立性较强,转变经济增长模式需要人力资本培养的密切配合。当期人均实际GDP增长率提高1%的话,下期人力资本增长率会降低2.26%,即人均实际GDP增长速度的波动对人力资本增量的变化有明显作用。政策上看,应早日建立市场主导式人力资本培养模式,增加人力资本培养主体的灵活性,从而更好地满足经济增长对要素投入的需求。     

The Determinants Of The Adoption Of Advanced Manufacturing Technology

The paper investigates empirically the decision of firms to adopt ‘Advanced Manufacturing Technologies’ (AMT) based on a comprehensive specification of a ‘rank model’ of technology adoption using firm-level data for Swiss manufacturing. The explanatory variables include numerous dimensions of (anticipated) benefits from and costs of technology adoption allowing for uncertainty as well as for information and adjustment costs. Moreover, the effect of complementarities between various functional groups of AMT (design, fabrication, communication, etc.) as well as of learning from the use of previous technology vintages within such functional groups is analyzed, Finally, the size-dependence of the adoption decision is studied in detail. The model yields a quite robust pattern of explanation across estimates with different adoption variables (time period of introduction of AMT, intensity of use of AMT, etc.) with plausible differences of the results based on the alternative adoption measures used.
