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

Using patent data for a panel sample of European companies between 1995 and 2016 we explore whether the inventive success in Artificial Intelligence (AI) is related to earlier firms’ innovation in the area of Information and Communication Technology (ICT), and identify which company characteristics and external factors shape this performance. We show that AI innovation presents strong dynamic returns (learning effects) and benefits from complementaries with knowledge earlier developed in the area of network and communication technologies, high-speed computing and data analysis, and more recently cognition and imaging. AI patent productivity increases with the scale of firm innovation, and is lower for companies with narrow technological competences. There is evidence of knowledge spillovers from ICT innovators to AI innovators, but this effect is confined to the frontier firms of the new technological field. Our findings suggest that, with the take-off of the new technology, the technological lead of top AI innovators has increased due to the accumulation of internal competences and the expanding knowledge base. These trends help explain the concentration process of the world’s data market. 相似文献

Strategic alliances are important channels for interfirm learning, especially for small firms that are resource constrained. Of the several alliance attributes, technological distance between partners (measured as the distance between partners’ innovative outcomes) is shown to have a significant influence on the learning benefits from strategic alliances. Drawing upon the theory of recombination, our study argues that the influence of technological distance on learning is best understood by not only measuring the distance between innovative outcomes, but by also taking into consideration the knowledge elements underlying the innovative outcomes. We develop a concept of knowledge base homogeneity that captures the extent to which the innovative outcomes of partnering firms draw upon similar sets of knowledge elements. Using patent and alliance data from 201 small biotechnology firms during the period 1996–2010, we confirm that the technological distance has an inverted u-shaped relationship on interfirm learning. We further demonstrate that this u-shaped relationship is moderated by the knowledge base homogeneity between partners, such that benefits of technological distance are enhanced and the costs of technological distance are mitigated when the knowledge base homogeneity between alliance partners is high. The results have important implications for interfirm learning, especially in the context of small firms that are limited in their knowledge stocks. 相似文献

Knowledge-relatedness in firm technological diversification 总被引：4，自引：0，他引：4
This paper claims that knowledge-relatedness is a key factor in affecting firms’ technological diversification. The hypothesis is tested that firms extend the range of their innovative activities in a non-random way. Specifically, we test the extent to which firms diversify their innovative activities across related technological fields, i.e. fields that share a common knowledge base and rely upon common heuristics and scientific principles. The paper proposes an original measure of knowledge-relatedness, using co-classification codes contained in patent documents, and examines the patterns of technological diversification of the whole population of firms from the United States, Italy, France, UK, Germany, and Japan patenting to the European Patent Office from 1982 to 1993. Robust evidence is found that knowledge-relatedness is a major feature of firms’ innovative activities. 相似文献

We investigate how outside directors on supervisory boards influence innovative activities of the firms they advise and monitor. Based on panel data on the largest German companies, the econometric analysis shows a positive influence of external executives on innovative firm performance, measured by patent applications. Differentiating between outside directors from innovative and non-innovative companies reveals that only outside directors from innovative firms increase patenting activities at the firms they advise and monitor. This effect increases with the technological proximity between the appointing firm and the outsider's home firm. Outside directors from non-innovative firms are negatively associated with the appointing firm's innovativeness. The results indicate that external executives with an appropriate professional background can provide valuable specific knowledge and expertise to the board. 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

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

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

基于开放式创新的过程管理思想,考虑一个由知识源、知识转移中介、信息服务机构组成的闭环知识链系统,通过构建知识源领导(SL)、知识转移中介领导(OL)与信息服务机构领导(TL)等博弈模型,分析了权力结构对知识供给、转换、反馈等环节的创新绩效的影响。研究表明,掌握领导权可提高组织的知识产出、知识定价与创新利润;在创新绩效表现上,SL模式是分散决策时的最优权力结构;OL与SL模式具有同等的知识创造效率,但OL模式系统利润偏低并存在组织间的利益冲突风险;市场机遇、合作伙伴的创新能力与组织的知识创造效率正相关,弥补知识链成员创新能力的短板是提高系统创新绩效的关键。 相似文献

This paper investigates how technological diversification influences the rate and specific types of innovative competence. We test a set of hypotheses in a longitudinal study of a sample of biotechnology firms. Our findings provide strong support for the premise that a diversified technology base positively affects innovative competence. Furthermore, technological diversification is found to have a stronger effect on exploratory than on exploitative innovative capability. This empirical evidence suggests that technological diversity may mitigate core rigidities and path dependencies by enhancing novel solutions that accelerate the rate of invention, especially that which departs from a firm's past activities. 相似文献

In the era of “alliance capitalism”, the increasing number of strategic technological partnerships (STPs) has been mainly recorded in the science-based fields, of which information and communications technology (ICT) is a leading sector. The establishment of STPs has also characterised the European ICT industry. The growing technological interrelatedness and the need to acquire capabilities in related fields have been identified in the literature as major explanations for the increase in corporate technological co-operation. This paper investigates the role of corporate technological specialisation factors in the conclusion of STPs in the European ICT industry by carrying out a dynamic analysis. Accordingly, the patterns followed by corporate technological partnerships in the industry in question are investigated since the late 1970s. Based on US patent data granted to the world's largest firms as well as STPs data, the results of the econometric analysis are consistent with the view that the more similar partners' technological portfolios are with one another, the easier it is to absorb each other's capabilities. 相似文献

This paper presents data from Brazilian Patent Office (Instituto Nacional de Propriedade Industrial, INPI) and compares them with data from the United States Patent Office (USPTO). Developing countries have technological activities that are important locally but not significant at international level (imitation, local learning, adaptation of foreign innovations). These activities might be patentable only at national level. Therefore, the study of domestic patents of developing countries provides a broader picture than USPTO patents. This paper compares 8309 INPI patents with 475 USPTO patents (between 1980 and 1995). Domestic patent data show peculiarities in the Brazilian case, possibly shared with other countries in similar technological level: (a) high share of individual patents; (b) foreign-owned firms with important activities; (c) low firm involvement in R&D activities. Some characteristics are shared with developed countries: (a) domestic firms as the major patentees; (b) according to firm size, there is a U-shaped distribution of patents; (c) evidences of multi-technology large firms; (d) a relatively small share of firms have more than one patent in the whole period. The contrast between USPTO and national patenting statistics shows different rankings according to ownership structure, leading firms, industrial sectors, and international patent classification. These differences highlight sources of international competitiveness and point to weaknesses in Brazilian innovative activities. This paper concludes evaluating the contributions (and weaknesses) of this database for the evaluation of the Brazilian National System of Innovation. 相似文献

Building on Lee and Malerba’s (2017) framework, we explore how leading firms in Brazil’s forestry and pulp industry responded to windows of opportunity, in learning terms, shaping an early entry into path-creation technological catch-up, shifting that industry into a globally leading position. Drawing on an in-depth inductive study based on 50 years of evidence, a 10-year fieldwork in large firms, and on a novel approach to micro-level external and internal absorptive capacity (AC), as empirically observable external and internal learning mechanisms (LMs) underlying firms’ innovative capability accumulation (technological catch-up), we find that: (1) firms responded to changing windows of opportunity by developing dual AC through the intensity and the manner of use of multiple LMs across the emergence, gradual catch-up, and forging-ahead phases of the path-creation process; (2) however, there were variations within and across firms in the effectiveness with which they developed their dual AC over these phases, leading to a non-homogenous technological catch-up: while some firms reached a world-leading capability level, others became fast-followers. We contribute to deepening and refining the understanding of technological catch-up through robust empirical insights on how the dynamic interplay between windows of opportunity and variation in the micro-level dual AC development’s effectiveness helps to explain the nature and extent of firms’ technological catch-up. We also provide a basis to further the analysis of technological catch-up and its learning processes, particularly in natural resources-rich industries in resource-rich developing countries. 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

Better understanding of, and policies towards, technical change, requires better measurement of technical change. No single measure is perfect. Taken together, statistics on R&D and on patenting activities give important clues about the rate and direction of innovative activities, and also show the dangers of too hasty interpretation based on one measure. They both show a neavy concentration of innovative activities in chemicals and engineering (electrical, electronic and non-electrical) sectors; relatively rapid growth of innovative activities in drugs, scientific instruments and food products, and slow growth in aerospace and electrical products, in the USA between 1963 and 1974. They both show relatively high levels of innovative activities in Germany, Sweden and Switzerland, and relatively rapid rates of increase in Japan and Sweden between 1967 and 1975. They also show the strong association in the chemicals and engineering industries between the levels of innovative activities and of export competitiveness.On the other hand, taken together they suggest that patent statistics underestimate innovative activities in large firms, and that R&D statistics do so in small firms. This casts doubt on widely held assumptions about diminishing rates of innovative activity in very large firms, and about the non-electrical machinery and fabricated metal products sectors as “traditional” and “non-innovative” industries. Four factors are put forward to explain differences in what is shown by the patent and by the R&D measures: First, competitive behaviour, with smaller firms making a relatively greater use of patents, and bigger firms of R&D activities; second, different degress of specialisation and formalisation of innovative activities in and around R&D departments; third, variation across sectors in the degree to which patents measure an increment of technical improvement; fourth, institutional factors in aerospace and other defence-related sectors, and in motor vehicles, where patenting is low and the proportion of routine testing in R&D comparatively high. 相似文献

Mergers and acquisitions: Their effect on the innovative performance of companies in high-tech industries 总被引：6，自引：0，他引：6
This study examines the post-M&A innovative performance of acquiring firms in four major high-tech sectors. Non-technological M&As appear to have a negative impact on the acquiring firm's post-M&A innovative performance. With respect to technological M&As, a large relative size of the acquired knowledge base reduces the innovative performance of the acquiring firm. The absolute size of the acquired knowledge base only has a positive effect during the first couple of years after which the effect turns around and we see a negative effect on the innovative performance of the acquiring firm. The relatedness between the acquired and acquiring firms’ knowledge bases has a curvilinear impact on the acquiring firm's innovative performance. This indicates that companies should target M&A ‘partners’ that are neither too unrelated nor too similar in terms of their knowledge base. 相似文献
