基于“IO-TL”模型的公司多元化逻辑

本文从现有多元化争论现象出发,分析了公司多元化诱因,阐述了多元化影响因素,在此基础上构建公司多元化产生的“IO-TL”模型,随后从动态视角深入分析了多元化“IO-TL”模型,并推理出公司多元化逻辑:公司多元化行为由公司所面临的行业秩序和自身的技术水平状况共同决定,短期内,公司最优多元化程度是存在的、稳定的;从长期来看,公司最优多元化程度随公司所面临的行业秩序和自身的技术水平发展而不断变化     

东亚信息技术产业的区内与区外贸易模式实证分析

东亚IT产业发展的贸易模式有如下特点：第一,东亚IT产业的技术来源于美国。通过承接美国计算机企业的“外包”业务,东亚在IT硬件设备制造领域建立了完整的生产体系。第二,东亚与美国的IT产品贸易主要集中在集成电路与电子部件。反映了美国企业将IT中间产品“外包”到东亚区域以降低生产成本,推动了全球IT产品的国际外包浪潮。第三,东亚区域内贸易模式不同于东亚-美国之间的贸易特征．日本、韩国和东盟通过向我国出口集成电路及其电子零部件获得了巨额的贸易顺差,而我国则将进口的集成电路和电子零部件装配成电子产品出口到美国和世界各地。

Technology ladders and R&D in dynamic Cournot markets

Motivated by dramatic and unpredictable technological advances in energy production (for instance drilling and extraction of shale oil), we extend Cournot models of competition to incorporate research and development (R&D) that can lead to (stochastic) drops in production costs. Our model combines features of patent racing with dynamic market structure, capturing the interplay between the immediate competition in terms of production rates and the long-term competition in R&D. The resulting Markov Nash equilibrium is found from a sequence of one-step static games arising between R&D successes, and several numerical examples and extensive analysis of the emerging comparative statics are presented. Analyzing the relationship between current market dominance and the level of R&D investments, we find that market leaders tend to invest more, which in some sense makes oligopoly dynamically unstable. We show that anticipated market transitions have long-term impact; for example the potential of future monopoly can spur R&D investment now, even if the firm is presently uncompetitive and not actively producing. We also show that, surprisingly, random innovations have an ambiguous effect on R&D. This feature, which is driven by the Cournot framework, contrasts with the common situation whereby uncertainty lowers innovation and delays R&D investments. Finally, we demonstrate that increased competition may actually increase efforts to innovate through higher desire to achieve dominance. This would match the anecdotal evidence that the threat of market entrants forces incumbents to maintain high R&D.     

Technology fusion: Identification and analysis of the drivers of technology convergence using patent data

The concepts of technology convergence or technology fusion describe the phenomenon of technology overlap. Despite evidence of the higher value associated to interdisciplinary research and cross-industry innovation, few studies have investigated the characteristics of technology fusion based on patent data. This study identifies new cases of convergence relying on the International Patent Classification (IPC) of patents filed at the European Patent Office between 1991 and 2007: the first occurrence of a patent incorporating a combination of IPC subclasses signals a new instance of fusion. Duration models are employed to investigate the impact of field level characteristics derived from patent bibliometrics on the likelihood of identifying a new fusion. The results show that merges are more frequent if the focal technology fields are closely related (based on a higher number of cross citations), are characterized by wide technological scope, and are the result of an inter-firm collaboration. In contrast to previous findings, the results show that the more complex the technologies involved, the less the likelihood of their convergence or fusion. The correlation between fusion likelihood and the characteristics of the merging fields could help managers and policymakers to predict the emergence of new technology areas.     

Technology upgrading of Small-and-Medium-sized Enterprises (SMEs) through a manpower secondment strategy – A mixed-methods study of Singapore's T-Up program

This paper outlines a scheme that uses manpower from public research institutes to assist the technology upgrading of Small-and-Medium-sized Enterprises (SMEs). The Growing Enterprises through Technology Upgrading (GET-Up) initiative has been successfully implemented in Singapore since 2003. The key program in the initiative is a manpower secondment scheme (i.e. a temporary placement of manpower in a different organization) known as T-Up. We propose that T-Up represents a new approach to technology transfer which additionally maximizes the industrial impact of public sector research. Instead of traditional technology transfer modes which are transactions-based, T-Up utilizes skills and human resource transfer through secondment of public sector researchers. Findings from two surveys conducted in 2005 and 2012 show that the T-Up secondment program had positive impact on the technological capabilities, innovation performance and growth of participating companies. Additionally, case studies highlight that this approach addresses a wide range of challenges faced by local SMEs and is flexible enough to cater to specific needs and requirements.     

You'll never walk alone: Why we need a supply chain practice view on digital procurement

This paper conceptualizes digital procurement readiness as a dyadic construct and introduces the supply chain practice view (SCPV) as a theoretical lens that can help guide future research on digital procurement. We build on a literature review and on dyadic, explanatory case studies to provide a nuanced understanding of how the digital readiness of supply chain partners—on both sides of the dyad—needs to co-evolve for the implementation of digital procurement practices. Specifically, we outline how the SCPV can serve as both a holistic and a supply chain-specific framework for future research on the following: 1) the antecedents that help explain why supply chain partners adopt inter-organizational digital procurement practices, and 2) the relational performance outcomes derived from their use. For managers, this study implies the need to explicitly consider interactions with and influences of supply chain partners in their quest to rapidly and effectively digitalize procurement.

Policy-driven ecosystems for new vaccine development

This paper examines the relationship between biomedical policies and entrepreneurial R&D strategies. Public health programs have been unable to provide effective and affordable treatment of infectious diseases for the poor. While governments have become more open to private sector contributions to policy objectives, it is rare to find new ventures commercializing healthcare innovations for neglected diseases. Two case studies of entrepreneurial ventures, in the UK and China, provide evidence on how resource-constrained firms mobilize participants in policy-specific ecosystems to achieve their goals of new vaccine development for tuberculosis. Ecosystem analysis reveals how the innovators’ business models can align their strategies with national policy objectives.
