Identifying R&D partners through Subject-Action-Object semantic analysis in a problem & solution pattern

Today’s companies still rely heavily on expert knowledge rather than quantitative data with a systematic approach to effectively identify and choose Research and Development (R&D) partners. It is advantageous to identify and select potential R&D partners using a Problem & Solution (P&S) pattern. This paper presents a novel process for identifying R&D partners on the basis of solution similarities that assist technology managers in understanding the relationships between research targets. First, we choose a thematic dataset that contains problems and quantitative data with relative topic terms. Then, we extract Subject-Action-Object semantic structures in a P&S pattern from the dataset, and identify various solutions to a technical problem, with each as a subject. In addition, we provide correlation mapping to visualise the text characters and identify R&D partners. Finally, we validate the proposed method through a case study of the dye-sensitized solar cells sector.

Are multinationals exporting jobs? The case of Taiwan

Does offshore production always result in job exportation? Using firm‐level data for Taiwanese multinationals that allow us to avoid reverse causality issues, this paper finds that while increasing offshore production has a negative impact on the demand for domestic manufacturing workers, this is not the case for domestic research and development workers who are often more skilled. The results also suggest that for Taiwan, there is geographical fragmentation of production activities in such a way that more skilled jobs are maintained domestically and less‐skilled jobs are exported to other developing countries. These findings confirm the prediction of the knowledge‐capital model.     

Perceptions of task cohesiveness and organizational support increase trust and information sharing between host country nationals and expatriate coworkers in Oman

Information sharing between expatriate and host country national (HCN) employees is strategically significant. In a sample of Omani HCNs, we hypothesize and find that perceiving task cohesiveness is positively associated with HCNs’ willingness to share information with expatriates and that trust mediates this association. In addition, perceiving organizational support strengthens the relationship between expatriates’ task cohesiveness and HCNs’ trust, whereas interpersonal similarity has no influence. This research highlights important ways in which trust and information sharing may be encouraged, and that HCN–expatriate interpersonal similarity is less important to building trust when more diagnostic cues are available.     

Do Asian stock market prices follow martingales? Evidence from spectral shape tests

This paper examines the martingale hypothesis for five Asian stock markets using the spectral shape tests of Durlauf (1991). Unlike the variance ratio test employed in previous studies (eg, Panet al, 1991), the spectral shape tests are consistent againstall stationary alternatives to the martingale null.The spectral shape tests were applied to daily and weekly returns on the stock indices of Thailand, Hong Kong, Korea, Malaysia and Taiwan over a period of 17 years. The results show that the martingale null is rejected for most markets. There is some evidence that the rejections may be due to low frequency or long memory influences.The authors are lecturers, Department of Finance and Banking, National University of Singapore. This paper was presented at the Third International Conference on Asian-Pacific Financial Markets, September 9–11, 1993 in Singapore. We have benefited greatly from the comments of Y K Tse and other conference participants.     

当前中美贸易摩擦问题的政策分析

由于中国已成为美国最大的贸易逆差来源,且这种贸易不平衡短期内不会解决,而中美贸易摩擦在未来较长时期却会存在。所以对该问题产生的背景原因、集中体现、结论对策进行深入分析就显得十分重要。     

新型产业组织分析范式构建研究——从SCP到DIM

随着现代产业分工的精细化与企业间关系的网络化发展,产品之间的竞争已经由单个企业与单个企业之间的竞争转变为企业簇群与企业簇群之间的竞争。本文以此为出发点,通过引入产品价值网络的概念体系,试图在整合、修正传统SCP分析框架的基础上,构建一个基于模块化理论的新型产业组织分析范式——“DIM”①分析框架,以期从立体多维层面实现对现代产业组织结构、行为、绩效的更为全面研究。     

Ownership, institutions, and capital structure: Evidence from China

We employ a unique data set to explore the role of ownership structure and institutional development in debt financing of non-publicly traded Chinese firms. We show that state ownership is positively associated with leverage and firms’ access to long-term debt, while foreign ownership is negatively associated with all measures of leverage. Surprisingly, firms in better developed regions are associated with reduced access to long-term debt, suggesting the availability of alternative financing channels and the tightening of the lending standards under the on-going banking reform. The combination of ownership structures and institutions explains up to 6% of the total variation in firms’ leverage decisions, while firm characteristics alone explain no more than 8% of the variation. Further, we show that non-state-owned firms tend to have lower total and short-term debt than their state-owned counterparts in less developed regions. Finally, we show that state-owned firms’ easy access to long-term debt is positively associated with long-term investment and negatively associated with firm performance.     

当前顺差、外汇储备和资产泡沫关系探讨

2006年我国贸易顺差达到创历史纪录的1774.7亿美元.顺差过多导致外汇储备过多,人民币升值压力增大,使得宏观调控特别是货币政策效果减弱,并且催生货币流动性过剩,导致国内股市和房地产有泡沫化趋势.目前大多数观点认为这种资产泡沫化趋势如不采取有力措施尽快调控将产生重大危害.本文认为过度资产泡沫很可能演变为金融危机,但是温和的泡沫对于目前国内经济是有利的.通过制定合理的政策,可以发挥资产泡沫的正面作用,缓解目前产能过剩与顺差的问题.     

国家级新区功能定位及发展建议——基于GRNN潜力评价方法

从规模总量、经济外向性、创新能力及交通区位4个方面的18个指标构建国家级新区发展潜力评价指标体系,运用GRNN(广义回归神经网络)方法,以9个国家级新区及8个具有重要国家级新区潜质的区域(后统称新区)为对象,对其母城进行新区发展潜力综合评价。研究发现:1新区发展潜力差距较大,其中上海、深圳、广州和天津的新区在发展潜力上具有绝对优势;沿海新区普遍经济外向程度高于内陆新区;重庆是内陆唯一一个可与上海、深圳、广州和天津媲美的国家级新区母城,其在规模总量和经济外向性方面具有显著优势。2在对GRNN评价结果进行聚类分析的基础上,将17个新区分为国际竞争型、全国中心型、区域中心型和特殊战略型4类功能模式。文章最后结合各新区设立的战略目的和潜力评价结果,梳理了不同类型新区功能关联,并针对不同功能模式的新区在其母城支撑条件下,实现其功能定位的实施路径进行了初步探讨。
