Monitoring trends of technological changes based on the dynamic patent lattice: A modified formal concept analysis approach

The strategic importance of monitoring technological changes is highlighted given the ever faster pace and increasing complexity of technological innovation. In this respect, patent citation analysis has been the most frequently adopted tool among others. However, patent citation analysis is subject to certain drawbacks that stem from only consideration of citing-cited information and time lags between citing and cited patents. This study proposes a formal concept analysis (FCA)-based approach to developing a dynamic patent lattice that can analyze complex relations among patents and monitor trends of technological changes. The FCA is a mathematical tool for grouping objects with shared properties based on the lattice theory. The distinct strengths of FCA, vis-á-vis other methods, lie in structuring and displaying the relations among objects from a massive amount of data. For the purpose of technology monitoring, the FCA is modified to take into account time periods and changes of patent keywords. A patent context is first constructed with the aid of domain experts and text mining technique. Two types of dynamic patent lattices are then developed by executing the modified FCA algorithm. A case study of laser technology in lithography for semiconductor manufacturing shows that the suggested dynamic patent lattice has considerable advantages over conventional patent citation maps in terms of visualization and informative power.     

Biological conservation in dynamic agricultural landscapes: Effectiveness of public policies and trade-offs with agricultural production

Land use change and land management intensification are major drivers of biodiversity loss, especially in agricultural landscapes, that cover a large and increasing share of the world's surface. Incentive-based agri-environmental policies are designed to influence farmers' land-use decisions in order to mitigate environmental degradation. This paper evaluates the effectiveness of agri-environmental schemes for biological conservation in a dynamic agricultural landscape under economic uncertainty. We develop a dynamic ecological economic model of agricultural land-use and spatially explicit population dynamics. We then relate policies (subsidies to grassland, taxation of agricultural intensity) to the ecological outcome (probability of persistence of a species of interest). We also analyze the associated trade-offs between agricultural production (in value) and biological conservation (in probability of persistence) at the landscape scale.     

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.     

货币冲击与中国经济波动——基于DSGE模型的数量分析

基于1993~2008年的季度数据,本文在一个包含Calvo价格粘性的新凯恩斯主义模型中,讨论了中国货币冲击与经济增长的关系。在假定货币政策通过调整货币供给增长实施的前提下,本文根据模型模拟和实际数据的对比以及脉冲响应函数分析得出以下结论:(1)货币并非我国经济波动根源,实际产出对货币供给具有一定反馈作用。(2)通货膨胀的顺周期性和领先增长表明中国经济周期存在总需求拉动的特性。物价波动在中短期主要由货币供应量波动引起。(3)货币政策对实体经济有效但效果有限,货币供给变动对投资的作用效力更大,对消费需求刺激有限。     

中国和印度贸易模式的比较研究

中国和印度作为两个较大的发展中国家,具有很多共同点,但在对外贸易上存在很大的差异。研究中国和印度对外贸易上的表现,结果发现:两个国家近年来都有较高的外贸依存度,但中国在世界出口中的比重不断上升,而印度在世界出口中所占的比重很小且保持不变;两个国家的贸易在很大程度上是产业内贸易,中国比印度出口更多复杂和精细的产品。中印两国贸易模式存在差异的主要原因是,中国较早注意利用劳动力资源禀赋发展加工贸易,印度对于外向型经济的相关政策出台较晚。     

二氧化碳排放强度下降目标的动态分解研究——基于“十二五”规划目标的分析

针对十二五规划中二氧化碳排放强度下降17%的目标,设定两种分解路径——等比路径和等差路径,采用数理经济学理论,将之分别对应到二氧化碳排放强度和人均国内生产总值两项指标的幂函数路径和对数函数路径。根据1990~2007年全球主要地区和中国的历史经验数据,对上述两个函数的参数进行模拟,并对二氧化碳排放量路径进行预测。研究发现,幂函数最优路径比国际经验对应的最优路径更为激进;幂函数最优路径比对数函数最优路径更为灵活,但后者减排潜力更大。若走对数函数路径,在远期保持国内生产总值年均7%增长速度的前提下,到2038年我国将达到二氧化碳排放量的峰值,之后便逐步下降。     

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.     

I Have Paid Less Than You! The Emotional and Behavioral Consequences of Advantaged Price Inequality

This study examines the emotion blends and the subsequent customer reactions that occur in advantaged price inequality situations, that is, when consumers learn that retailers charged them a lower price than what the same retailers charged another customer. Drawing on the appraisal theories of emotion and on social comparison theory, an experiment (n = 272) and a field study (n = 261) are conducted. The results reveal that in advantaged price inequality situations, customers experience a host of positive and negative emotions depending on two factors: the quality of relationship that the customer has with a disadvantaged other customer (neutral, positive, or negative) and the attribution of agency for the price advantage (situational attribution to competition, external attribution to store policies, or internal attribution to customer abilities). Positive emotions include happiness, gratitude, pride, and malicious joy; while negative emotions include pity, outrage, and guilt. These emotions are shown to mediate the occurrence of customer reactions (i.e., customer satisfaction, loyalty, WOM referral, and WOM activity). The article concludes with theoretical implications and recommendations for retail practitioners on how to use dynamic pricing.     

关于旅游业跨国经营动因的思考

政府一方面是以各种各样的优惠政策积极吸引外资投资中国旅游业,另一方面又在积极推动本国旅游企业走出去跨国经营。对于这种似乎矛盾的现象需要从旅游业跨国经营的动机、跨国经营优势交换及全球化学习背景下的整体利润观等角度进行解读,对跨国经营优势概念也需要从体系化角度进行新的解读。     

关于国际技术扩散对我国贸易竞争优势影响的思考

在经济全球化的进程中,一国的技术进步不仅依赖于本国的创新,而且还需要充分利用他国的先进技术资源,并通过各种渠道的技术扩散和技术外溢来促进本国的技术进步与经济增长,从而在国际市场上提升本国的贸易竞争优势。结合我国现状从宏观和微观两个角度分析了国际技术扩散对我国贸易竞争优势的影响。
