The principle of relatedness allows us to explore the likelihood that territories diversify their current technological portfolios based on the global co-occurrence patterns of technologies. Countries that excel at developing semiconductors should develop mobile phones because both technologies require similar endogenous capacities, including scientific knowledge. However, thus far, studies have been mostly limited to the knowledge common base assumption and have not questioned enough whether different scientific endogenous capacities may be behind similar diversification performances. To address this question, we introduce the concept of scientific and technological cross-density, which we define as the average proximity of a new potential technology to a country's scientific and technological portfolio. To conceptualize and measure the effect that scientific and technological cross-density may have on technological diversification, we applied a two-stage methodology to a sample of 182 countries during the 1988–2014 period. First, we build a network, the science and technology cross-space, (sci-tech cross-space), which relates knowledge and technologies based on co-occurrence values. Second, we estimate the effect of scientific-technological cross-density and technological density on technological diversification at the country level. We find that the more a new technology is related to a country's scientific portfolio, the greater its entry probability; additionally, the effect of technological density on technological diversification is greater than the effect of scientific and technological density.  相似文献

Innovative public procurement is increasingly considered as a form of public support for private innovation activities by both innovation scholars and policymakers. Economic historians have suggested an even more fundamental role of public procurement in setting the pace of technological change, reporting how defense-related procurement has had a major impact on the emergence and diffusion of many general purpose technologies developed in the United States in the 20th century. In this paper, I suggest that procurement might represent one of the most important elements in creating the right soil to ‘cultivate’ a technology that may have the potential to reach high levels of pervasiveness. To test this hypothesis, I make use of patent data and patent citations. I design a quasi-experiment to compare the changes in the level of generality level over time, between a group of treated and a group of control patents. A patent is assigned to the treatment group if it receives a citation from a patent related to public procurement. Results suggest a positive and significant impact of innovative public procurement on the generality of a patent.  相似文献

The theoretical literature on technological changes distinguishes between paradigmatic changes and changes in trajectories. Recently several scholars have performed empirical studies on the way technological trajectories evolve in specific industries, often by predominantly looking at the artifacts. Much less - if any - empirical work has been done on paradigmatic changes, even though these have a much more profound impact on today's industry. It follows from the theory that such studies would need to focus more on the knowledge level than on the artifact level, raising questions on how to operationalize such phenomena. This study aims to fill this gap by applying network-based methodologies to knowledge networks, represented here by patents and patent citations. The rich technological history of telecommunications switches shows how engineers in the post-war period were confronted with huge challenges to meet drastically changing demands. This historical background is a starting point for an in-depth analysis of patents, in search of information about technological direction, technical bottlenecks, and engineering heuristics. We aim to identify when such changes took place over the seven different generations of technological advances this industry has seen. In this way we can easily recognize genuine paradigmatic changes compared to more regular changes in trajectory.  相似文献

Under what conditions does digital technology adoption increase cross location knowledge flows within firms? We investigate this question by studying the impact of adopting basic Internet access on cross-location knowledge flows within the same firm. We construct a large data set of Internet adoption and patent citations among dyadic pairs of firm-locations between 1992–1998. We find that when both locations in the pair adopt basic Internet there is an increase in the likelihood of a citation between the citing and (potential) cited location. In contrast, we find no significant effect of Internet adoption at only the citing location. We further study how this effect varies according to the proximity of the research activities between the source and recipient of knowledge and specialization of the research activities within the recipient. We find that the likelihood of a citation increases more after dyadic Internet adoption when the pair is working in similar research areas and when the research areas in the citing location are less specialized. These results, which are robust to a range of robustness analyses, suggest that digital technologies such as Internet connectivity are able to facilitate knowledge flows between locations only when they share a common knowledge base.  相似文献

In this paper, we develop themes from complexity and chaos theory that help to explain the technological change process. We apply two quantifiers, correlation dimensions and Lyapunov exponents, to examine the signs and degrees of chaotic technological dynamics. To illustrate our ideas, we study the development of electronic displays from 1976 to 2010, using patent data. The results of the chaos model are matched against the profiles of patent citations. Our analysis contributes to the development of a chaotic model of technological change.  相似文献

This article critically assesses the utility of both personal blog and mass media (on-line newspaper)’s coverage of future technology in forecasting the prospect of industrial technology. By analyzing the statistical pattern of the South Korean media salience in 13 novel industrial technologies in 2015, the study argues that the mass media is more biased than aggregated blogs in depicting promising new technology. In doing so, the authors present a methodical pathway to address the bias with acceleration and skewness index. The article also applies semantic network analysis for the collected textual data of blogs to represent and interpret people's perspective of industrial technologies. By extracting key concepts from PBS index and merging semantic networks of the 13 technologies, the study derives a key insight that nurturing expertise in the coming era of artificial intelligence and robot would become crucial to integrate key technological competence.  相似文献

A frequently made claim in the innovation literature is that important inventions involve the transfer of new knowledge from one technological domain to another. This study uses U.S. patents granted from 1976 to 2006 to identify the role of knowledge acquired from outside each patent's technological domain. Our results do not seem to support the claim above. Increasing citations to external prior art is a significantly less important predictor of forward citation frequency than citing prior art that is technologically closer. This result is robust across several model specifications and ways of defining whether each flow of knowledge is external. The result is even stronger in the most highly cited technology categories. We discuss possible explanations for this apparently negative impact of external knowledge—including both measurement issues and challenges associated with assimilating disparate knowledge.  相似文献

Patent data have been widely used in research to characterize firms’ locations in technological or knowledge space, as well as the proximities among firms. Researchers have measured firms’ technological or knowledge proximities with a variety of measures based on patent data, including Euclidean distances (using the technological classifications listed on patents), and overlap in cited patents. Often research has employed only the first listed patent classification in measures of proximities. We explore the effects of using the first listed patent class as well as other methods to measure proximities. We point out that measures of proximity based on small numbers of patents are imprecisely measured random variables. Measures computed on samples with few patents or a single patent class generate both biased and imprecise measures of proximity. We discuss the implications of this for typical research questions employing measures of proximity, and explore the effects of larger sample sizes and coarser patent class breakdowns in mitigating these problems. Where possible, we suggest that researchers increase their sample sizes by aggregating years or using all of the listed patent classes on a patent, rather than just the first.  相似文献

This study investigates whether country-level technological disparities influence individual scientists’ choice of research agenda and, if so, how the effect of country-level technological disparities on individuals’ research activities differs before and after technology commercialization. To address these research questions, we use research proceedings published from the International Electric Vehicle Symposium (EVS) from 1990 to 2009. We find that a country’s technological capabilities tend to prevent its scientists from studying electric vehicles (defined as a disruptive technology) but encourage them to study hybrid vehicles (defined as a sustaining technology) before electric and hybrid vehicles are launched in the automobile market. We also find that a country’s technological capabilities do not subsequently help its scientists shift their research activities to the technologies that have received positive initial feedback from automobile markets.  相似文献

Does the presence of specialist technological expertise, diversity across industries and the intensity of competition among existing firms in a location affect the rate at which new firms are attracted to an agglomeration? We construct three measures of these explanators including a novel measure of competitive dynamics and estimate a region-industry panel fixed-effects model using data on a national census of firms over a 15-year period. This extensive panel dataset of firms and regions, enables us to move beyond the comparative static analysis which has dominated the agglomeration literature for so long. We find local competitive intensity has a large positive effect on firm creation. Competition attracts, not repels. Technological specialisation is a moderate attractee, but diversity may merely lead to local congestion.  相似文献

Do scientific capabilities in regions translate into technological leadership? This is one of the most pressing questions in academic and policy circles. This paper analyzes the matching of scientific and technological capabilities of 285 European regions. We build on patent and publication records to identify regions that lie both at the scientific and technological frontiers (strongholds), that are pure scientific leaders, pure technological leaders, or just followers in 18 domains. Our regional diversification model shows that local scientific capabilities in a domain are a strong predictor of the development of new technologies in that domain in regions. This finding is particularly relevant for the Smart Specialization policy because it implies that the analysis of domain-specific scientific knowledge can be a powerful tool to identify new diversification opportunities in regions.  相似文献

This paper addresses the question of how firms accomplish the strategic task of adapting their entire set of IORs (interorganizational relationships) to changing environmental conditions. To study this, we move beyond the focus on collaboration with individual partners (the dyadic perspective) that has been the dominant emphasis in the literature until now. Instead, we view the firms’ portfolios through the lens of the different modes of IOR engaged in (licensing agreements, non-equity alliances, venture capital investments, minority investments, joint ventures, and mergers & and acquisitions). We study the role of environmental change within the high-tech setting of the bio-pharmaceutical industry and distinguish between industry technological change and firm-specific technological change. In doing so, we rely on prospect theory to theorize how firms’ perceptions of environmental change in terms of a looming loss or a potential gain affect their risk-bearing, how this leads them to adjust their IOR portfolio diversity, and how these adjustments get implemented at the mode level. Whereas most of our hypotheses were confirmed by the study, a key unexpected finding was that firms respond to both types of technological change through stronger forms of adaptation than theoretically anticipated. Firms adapt to industry technological change through an increase in the diversity of their portfolio of IORs and by churning it up, which leads to a loosening of control at the individual mode level but greater adaptivity at the portfolio level. When facing firm-specific change instead, they adapt by reducing portfolio diversity, while cutting back on collaboration across five out of the six modes. Our findings both contribute to the literature on organizational adaptation, interfirm collaboration, and IOR portfolios and provide a greater behavioral understanding of network change.  相似文献

This paper extends the resource-based theory of the firm to examine the contingencies that either intensify or reduce the relationship between firm-specific innovation and value appropriation. Based on a large-scale analysis of a sample of US manufacturing firms, we found that greater innovation rents appropriation is associated with an increase in firm specificity of its innovative knowledge. But the positive relationship between firm-specific innovations and firm value appropriation tends to decrease when the product or technology market is highly dynamic. Further, under high environmental dynamism, firms should increase the diversity in their knowledge composition in order to mitigate the risk of value erosion associated with firm-specific innovations.  相似文献

As technical standards are an important part of China's industrial transformation towards an innovation-driven economy, Chinese organizations have started to deploy substantial resources in recent years to take on a leading role in international ICT standardization. However, many Chinese organizations experience, similar to other latecomers to standardization, limited success when contributing to standardization processes, a phenomenon also referred to as the standardization gap. The literature on standardization to date has paid little attention to how Chinese latecomers enter and influence international standardization processes that have traditionally been shaped by organizations from industrialized countries. We therefore analyze the country-of-origin effect as well as factors such as experience and collaboration for successful contributions of Chinese organizations to standards. Using data from the Third Generation Partnership Project (3GPP) and binary logistic regression analysis, we are able to show that, in our sample, contributions from Chinese latecomers are significantly less likely to be accepted than those from more established actors from industrialized economies. Moreover, our findings indicate that experience is closely associated with success in international ICT standardization, but not moderated by national origin. Therefore, Chinese latecomers might not be able to catch up if they move at the same pace as established competitors. They need to find a way to leapfrog extensive development steps, narrow the standardization capability gap, and thus strengthen their participation and influence. One way to do so might be through strategic collaboration, as our results suggest that Chinese organizations benefit more from collaborating with organizations from more established regions than vice versa, on which we call for further research to establish the causal mechanisms.  相似文献

Scientific and technological innovation policies play a critical role in the innovative development of high-technology industrial parks. However, it remains unclear how scientific and technological innovation policies impact the innovation efficiency of high-technology industrial parks and what the impact pathways are. An in-depth investigation of this topic can give an insight into the inherent relation between the scientific and technological innovation policies and technological innovation. By conducting a theoretical analysis, this study empirically analyzed the impact of scientific and technological innovation policies on the innovation efficiency of high-technology industrial parks. The main research methods applied in this study were linear regression and qualitative comparative analysis (QCA). The results showed that the policy targets drove innovation efficiency in a relatively minor way. Among all policy tools, the demand-based policy tools had the most significant influence on innovation efficiency. The supply-based and environment-based policy tools had notable positive impacts during the lag periods of policies. The policy mix pathways for scientific and technological innovation policies that impact innovation efficiency come in four forms, namely, the targets-directed, demand-driven, supply-dominated environment optimization, and environment-dominated comprehensive pathways. Therefore, this study put forward proposals on classifying and refining the scientific and technological innovation policies and optimizing the policy mix-driven models.  相似文献

Despite a substantial body of research investigating the market significance of inventions by independent inventors, relatively little attention has been devoted to understanding their technological significance. A recent study conducted by [Dahlin, K., Taylor, M., Fichman, M., 2004. Today's Edisons or weekend hobbyists: technical impact and success of inventions by independent inventors. Res. Policy 33, 1167-1183] on the tennis racket industry shows that independent inventors are a heterogeneous group which includes both “heroes” who contribute substantially to technological progress and “hobbyists” who make only a marginal contribution. What is not asked - and therefore not explained - is why this distinction arises. In this paper, we focus on the type of prior technological knowledge (in terms of technological specialization and diversity) applied by independent inventors and their corporate counterparts as a factor explaining differences in technological impact. Our empirical setting is the field of medical equipment technology. We find that independent inventors are more sensitive to the negative effects of technological diversity than their corporate counterparts. Furthermore, our study reveals that technological specialization pays off more for independent inventors than for their corporate counterparts. Therefore, those independent inventors who apply low degrees of diversity and high degrees of specialization are capable of reaching the same level as or even outperforming their corporate counterparts, thus becoming “heroes”. Based on our findings, we discuss implications for research and corporate practice.  相似文献
