为揭示机械产品突破性创新内在的动态演化机制,提出了一种基于突变理论的机械产品突破性创新耗散结构模型及其评价方法.首先叙述了耗散结构理论与熵变;然后应用发明问题解决理论(TRIZ)中的冲突解决原理分析了机械产品突破性创新尖点突变过程,建立了机械产品突破性创新耗散结构模型,指出了机械产品是在一个非平衡的开放系统中,系统内各技术子系统之间非线性相互作用下,以尖点突变的形式产生的宏观的“巨涨落”,从而形成的一种新的有序的耗散结构;最后基于信息熵理论提出了机械产品突破性创新的评价方法.以中药滴丸机为例,对2种不同状态下的滴丸机进行定量分析,结果较好地验证了该方法的合理性.  相似文献

为探究混合岩在不同围压下破坏过程中的能量演化特征和损伤演化规律,利用伺服试验机对混合岩进行了轴向压缩试验。结果表明,混合岩不同破坏阶段的弹性应变能、耗散能的变化情况不同,屈服强度之前,能量基本以弹性应变能为主,耗散能几乎为0,屈服强度之后,弹性应变能减小后保持稳定,耗散能急剧增加。基于试样弹性应变能与总吸收能之比的定量指标将试破坏的过程分为3个阶段,依此为裂隙稳定扩展阶段、裂隙加速扩展阶段和裂隙贯通阶段。将混合岩的损伤演化过程分为4个阶段,分别为初始损伤阶段、损伤稳定发展阶段、损伤加速发展阶段和残余损伤阶段。  相似文献

产业组织是以企业为核心,包括政府、大学、科研院所、中介机构等各产业主体在内,承担资金、技术、市场、人才、服务等产业要素配置功能,保障产业健康发展的核心载体。不同发展阶段的不同产业、不同企业对产业要素的配置需求并不相同,一个地区要保持产业快速发展、打造内生式的产业集群,就必须顺应产业成长规律和产业价值规律,进行产业组织创新。中国科技园区在不断地组织和优化产业要素的过程中,充分遵循市场经济发展规律,依托市场的力量,在发起设立、运作机制、职能定位和治理结构等多方面进行了一系列产业组织的创新实践。  相似文献

ABSTRACT

This paper deals with the role of the State Owned enterprises (SOEs) in innovation processes. Only a few studies focus on the contribution SOEs as companies might give to produce new knowledge and technological innovation. We argue, however, that SOEs are a pillar of the innovation process and we explore conditions that can make SOEs very effective. Through two in-depth case studies in two different industries (STMicroelectronics in the semiconductor and Thales Alenia Space in the space industry) we illustrate how SOEs can contribute to innovation by exploring new opportunities and recombining different sources of knowledge. We highlight the conditions that can make exploration and recombination possible. We also highlight the ability of the two companies to change their boundaries through a continuous wave of agreements, mergers and acquisitions. This way, they were able to expand beyond their domains in a way that matched the evolution of their original industries.  相似文献

After a buildup in the number of firms, new industries commonlyexperience a ‘shakeout’ in which the number of firmsdeclines sharply. Three theoretical perspectives on how technologicalchange contributes to industry shakeouts are analyzed. The theoriesare used to synthesize predictions concerning technologicalchange and industry evolution. The predictions inform an analysisof four US industries that experienced sharp shakeouts: automobiles,tires, televisions and penicillin. Using data on firm participationand innovation from the commercial inception of the four productsthrough their formative eras, we uncover regularities in howthe products evolved. The regularities suggest that shakeoutsare not triggered by particular technological innovations norby dominant designs, but by an evolutionary process in whichtechnological innovation contributes to a mounting dominanceby some early-entering firms.  相似文献

China’s economy and technology have experienced spectacular growth since the Opening-up Policy adopted in 1978. In order to explore the innovation process and development of China, this study examines the inventive activities and the collaboration pattern of university, industry and government (UIG) in China. This study analyzes the Chinese patent data retrieved from the United States Patent and Trademark Office. Three models of UIG relations which represent different triple helix configurations are introduced. According to the property of patent assignee, patent ownership can be divided into three types: individuals, enterprises, and universities and research institutes. Furthermore, enterprises can be classified into state-owned enterprise (SOE), private-owned enterprise (POE) and foreign enterprise (FE). The corresponding relationship of patent ownership with UIG is set up. Through analyzing the issued year, it is found that the inventive activities of China have experienced three developmental phases and have been promoted quickly in recent years. The achievement of innovation activities in China primarily falls on the enterprise, especially FEs and POEs. The innovation strengths of the three development phases have shifted from government to university and research institute and then industry. According to co-patent analysis, it is found that the collaboration between university and industry is the strongest and has been intensified in recent years, but other forms of collaboration among UIG have been weak. In addition, an innovation relation model of China was set up. The evolution process of innovation systems was explored, from etatistic model, followed by improved “laissez-faire” model, and then shifting toward triple helix model.  相似文献

The evolution of industry has recently attracted the attention of scholars studying the relationships between exploration and exploitation strategies and innovation performance. Surprisingly, although extant research has already acknowledged its multidimensional character, it has only been analyzed in an aggregate fashion. In this paper, we distinguish two components of the evolution of industry, the pace of market evolution and the pace of technology evolution, and we elaborate on their different impacts in the context of exploration and exploitation strategies. More precisely, we argue that while a rapid pace of technology evolution has opposite impacts on the relationships between exploration (positive), exploitation (negative) and innovation performance, a rapid pace of market evolution positively affects both exploration and exploitation. Our findings provide substantial support for our prediction using a large panel of Spanish innovating firms for the period 2008–2012.  相似文献

This paper presents a longitudinal study on the evolution of the retail banking sector in the UK following the adoption of automated payments in the 1970s. The analysis is cast in the context of innovation studies and articulates how changing configurations of the knowledge base combined with the emergence and adaptation of institutional structures stirred a paradigm of service innovation in an information‐intensive industry like banking. The cases of the Automated Teller Machine (ATM) and of the Electronic Fund Transfer at Point of Sale (EFTPOS) provide evidence on the subtleties of a dual evolutionary process underpinning the development of a system of innovation: the growing ecology of actors and the emergence of new forms of coordination across them.  相似文献

Since the cluster began to receive attention as a critical environmental factor in geographical economics, it has provided a major research methodology across multiple disciplines from industrial organization, strategic management, regional innovation system, and Triple Helix to virtual clusters. Network structure analysis (NSA) offers a common framework to observe clusters that have been studied separately from the viewpoint of industrial organization and strategic management. Industrial structure analysis, is based on the externality of a network and the resource-based view, focused on the inherent network capacity, have been combined with the study of structural changes through cluster NSA, to create a new direction for the growth of industry and individual firms. This study aims to analyze the correlation between the networking of structural change and a firm’s performance by selecting a software industrial cluster as a representative case for the knowledge industry. We examine the network structural positions of each node during the cluster evolution process. This empirical study has significance for establishing a firm’s growth strategy as well as supporting the policy about clusters, through outlining the dynamic evolution process of the networking activities in a knowledge industry cluster.  相似文献
