This paper studies the patterns of innovation in the ICT field using patents and patent citations. It provides an original methodology to identify ICT applications using patent abstracts and selecting the most frequent sequential triples of words without any a priori selection of keywords. This paper shows that the set of IPC classes related to ICT is broader than the one usually considered.Moreover, our results show that ICT applications can be distinguished into two main groups in terms of growth and structure of innovative activities, technological pervasiveness, and knowledge sources. High opportunity ICT applications are characterised by high growth of patenting activity, high rate of entry of new innovators and high concentration of technological activity across firms. They also display a diversified knowledge base in terms of technological domains and actors involved. Conversely, low opportunity ICT applications are characterised by a lower growth and by a lower concentration of innovative activities across firms, as well as by a lower rate of entry of new innovators. Innovations in these ICT applications show less diversified knowledge sources and a higher degree of internal knowledge base. 相似文献

Many eco-innovations have been linked to technical change in the ICT domain. Leveraging the distinctive features of general purpose technologies, ICT have the potential to steer green growth and to help decouple this growth from ecological damage. The paper aims to shed light on innovation dynamics in this emerging sector by investigating the patterns of innovation in the green ICT domains using granted EPO patent data from 1986 to 2006. By means of a network analysis, it identifies existing green ICT domains and examines the characteristics of innovative activity in these domains, focusing in particular on growth and technological pervasiveness, as well as on the variety of innovators. Results indicate that the innovative activity in green ICT domains is characterised by high growth and high levels of technological pervasiveness, considerable entry of new innovators and a variety of actors – with a prevalence of large ICT firms and universities. However, the analysis highlights the existence of three different clusters – emerging fields, established fields and mature fields – that are defined by different structures of innovative activities and by different technological opportunities. 相似文献

创新网络技术多元化知识基础与企业创新绩效 《科学学研究》2022,40(9):1698-1709
在新一轮科技革命浪潮下,企业组建创新联合体成为大势所趋。合作创新网络中的多元化技术已经成为企业创新的关键外部资源,但关于创新网络技术多元化如何影响企业创新绩效的研究仍然缺乏,且现有研究往往忽略企业内外部资源的不同组合对企业创新绩效可能产生的差异性影响。文章融合社会网络理论、知识基础理论与动态能力理论,依据信息技术产业上市公司联合申请专利数据构建合作创新网络,采用面板数据随机效应负二项回归法,从个体网络视角分析创新网络技术多元化影响企业创新绩效的权变因素与内在机制,检验了一个被中介的调节效应模型。研究结果表明：创新网络技术多元化正向影响企业创新绩效;企业知识基础深度正向调节创新网络技术多元化与企业创新绩效的关系,而企业知识基础宽度的调节效应并不显著;企业知识基础深度对创新网络技术多元化与企业创新绩效关系的调节通过吸收能力的中介实现。研究结论对企业技术创新具有重要的理论及现实指导意义。 相似文献

This paper investigates whether board directors interlocked with or employed by innovative firms affect start-up firms’ propensity to be innovators themselves. Drawing upon a sample of more than 50,000 Swedish start-up firms, we find that board connections to incumbent innovators have a causal impact on the new firms’ probability to apply for patents. The results are robust when controlling for industry, geography, firm age, as well as spillovers through worker and managerial mobility, external knowledge sourcing through patent disclosure, access to venture capital and board attributes. 相似文献

Technological imitation may play a crucial role in motivating firms to innovate. However, theoretical predictions and empirical findings on the role of imitation have not yet reached a consensus. One major gap in the previous studies is that the empirical tests are based on samples consisting of only one industry over a short period of time. This study uses a novel measure of industry-level technological imitation proxied by quick citations by competitors to examine the relationship between imitation and innovation. Using US patent data for the period 1977–2005, we find that there are inverted U-shaped relationships between the degree of industry-level technological imitation and industry-level innovation activities and between the degree of industry-level technological imitation and the value of firm-level innovation. Our results suggest that positive externalities from the interactions among firms during the innovation process outweigh the negative effects of free-riding concerns on firms’ innovation activities and incentives to innovate up to a high degree of technological imitation, while free-riding concerns outweigh the positive externalities when the level of technological imitation is extremely high. The sector-by-sector analyses show that the relationship between technological imitation and the quantity and market value of innovation are not very different across Pavitt sectors. A comparative analysis on the role of imitation between agglomerated and non-agglomerated industries suggests that the positive effect of a moderate level of imitation and the negative effect of an excessive level of imitation are more pronounced for agglomerated industries. The results suggest that creating innovation clusters, such as Silicon Valley in the United States and Shenzhen City in China, and allowing different innovators to cooperate, imitate and compete with each other would be very effective in promoting corporate innovation. However, an excessively high level of technological imitation is more detrimental for firms in innovation clusters because it lowers those firms’ incentives to innovate more radically. 相似文献

The purpose of this paper is to research firms’ knowledge management practices within the context of networked innovation between multiple actors. The analysis is based on case research carried out with six companies. Based on earlier literature and the theoretical framework of the paper, two models of networked innovation can be distinguished according to knowledge management needs: networks focusing on the transaction of explicit knowledge and intellectual property, and networks focusing on the co-creation of new knowledge and business opportunities. The paper argues that a strategic approach to knowledge management is a key element of success within networked innovation, both in the theory and in the practices of firms. In that way, firms are able to manage knowledge within networked innovation when they understand their partners’ business models and strategic intents, for example their motivation to collaborate. 相似文献

Business cycles modify firms’ incentives to innovate and the direction of innovation. By introducing a new measure of patent unconventionality this paper explores the impact of the business cycle on firms’ technological search strategies. We find that during upturns firms generate inventions characterized by a higher level of technological unconventionality. We also find that financially resilient and diversified firms produce more unconventional patents. While patent unconventionality is associated with technological impact and market value, firms extract more value by investing in unconventional inventions in downturns. 相似文献

Barriers to innovation have mainly been studied in a single country context. This paper studies differences in the perception of innovation barriers between innovative and non-innovative firms for 18 EU countries. The countries are grouped by their distance to the technological frontier using Community Innovation Surveys for the years 2002–2004 and 2004–2006. The results show that knowledge barriers related to the availability of skilled labour, innovation partners and technological knowledge are more important for firms located in countries close to the frontier, while the opposite is true regarding the availability of external finance. Moreover, while the share of innovators decreases with the distance to the technological frontier, the share of firms not interested or in no need of innovation increases. This is consistent with the idea that as firms approach the technological frontier, they increasingly need to focus on the creation of own knowledge and the adoption of innovation-based growth strategies to stay competitive. 相似文献

The traditional closed business models (BMs) are widespread and continue to dominate the current business world. Today, more and more companies are using outside technologies and innovations to develop new products and actively look at business opportunities created through sharing knowledge, competencies, and technological resources. The next phase is to open the business model to reap the full benefits of open innovation (OI). As the driver of effective knowledge and technology flows (inside-out and outside-in), open innovation cannot capture value of these flows unless it is leveraged by key internal resources. Based on the resource-based view (RBV), we claim that such technological investments cannot make organizations more effective unless they are accompanied by organizational complementary assets. Thus, the theoretical model exposes Open Business Model (OBM) antecedents based on a Business Model Innovation (BMI) perspective. Moreover, the literature of the BM innovation values the link between BM and OI and asserts that network, structures and technological knowledge management infrastructure are required to capture the value created by these flows and drive companies to open their BM and thrive.The paper performs a structural model analysis with a sample of 134 respondents in the information and communication technologies (ICT) based sectors. The results show the positive impact of technological knowledge management infrastructure on inbound OI and the impact of relational capital on the two types of OI strategies and in leveraging open BM in ICT-based sectors. The paper provides insights to firms OI initiatives holders to establish effective networked BMs. 相似文献

On the basis of a knowledge management perspective, this paper expands the literature on new ventures’ capabilities by considering how these firms fill knowledge gaps and develop the technological, marketing, management, and ICT capabilities they need to compete. In particular, this paper investigates the role of networks in these dynamics. Although new technology-based firms have great potential to introduce innovative products into the market, they might suffer from more critical knowledge gaps and capability weaknesses than established firms. The results of a quantitative investigation of an original data set of more than 400 Italian new ventures specializing in high-tech industries show that these firms acquire knowledge to support their capability growth mainly through the management of intense relations with multiple external sources of knowledge. In addition, capability development is supported by the variety of founders’ industry experience and the presence of young graduates among the founding team. 相似文献

This paper argues that spatial proximity plays a role in determining the propensity of firms to engage in R&D alliances. Drawing from economic geography, network theory and innovation theory, we discuss how prior collocation can affect the propensity to engage in R&D alliances, arguing that alliances can act both as a substitute and as a complement to collocation. Using a novel dataset matching alliances and patent data for the European ICT industry, we show that alliances are complementary to prior collocation (at both national and sub-national regional level) of firm’s R&D labs. In such an intra-industry, oligopolistic scenario, firms strategically use R&D alliances as a means to limit knowledge flows and protect competences, rather than to promote knowledge flows. Furthermore, while a common institutional context is important to promote collaboration, because of the high level of R&D internationalisation as well as the complex social networks within an oligopolistic industry, national institutional contexts are less relevant. 相似文献

基于技术融合的IT业专利宽度研究 总被引：1，自引：0，他引：1
由于IT技术的易扩散性和强渗透性,IT产业的技术创新不仅会扩散到同类企业形成模仿,还会扩散到相关联的下游企业形成技术融合。鉴于此,本文从社会福利最大化角度出发,通过建立上、下游企业的环形城市模型,研究技术融合下IT产业的专利保护宽度的决定机制。本文认为技术创新产生的社会福利不仅包括上游企业创新和模仿产生的社会福利,还包括下游企业技术融合创造的社会福利。模型结果表明,技术融合下IT产业的最优宽度是创新程度、企业的吸收能力、消费者多样性偏好、环形城市总长度的减函数,是下游企业数、融合产品需求曲线斜率的增函数。 相似文献

The role of corporate technology strategy and patent portfolios in low-, medium- and high-technology firms 总被引：2，自引：0，他引：2
Ulrich Lichtenthaler 《Research Policy》2009,38(3):559-569
Previous research into technology strategies and patent portfolios has focused on high-technology firms, whereas low- and medium-technology companies have been relatively neglected. Therefore, we analyze how corporate technology strategy and the size and composition of patent portfolios affect the performance of low-, medium- and high-technology firms. Data from 136 European companies are used to examine four hypotheses relating financial performance to technological diversification, technological aggressiveness, patent portfolio size, and patent portfolio quality. The cross-industry sample allows analyzing the different consequences of these strategic parameters in low-, medium- and high-technology firms by considering technological intensity as a moderator. Our first finding is that the positive impact of technological aggressiveness is limited in low- and medium-technology companies. Secondly, technological diversification has a positive effect in high-technology firms and a negative effect in low-technology firms. Thirdly, patent portfolio size has a positive effect only in high-technology firms. Finally, patent portfolio quality has an equally positive influence on all firms’ performance. In part, these results conflict with the findings of previous research into high-technology companies, and they call for rethinking the role of technology strategies and intellectual property portfolios in firms across industries. 相似文献
