Appropriability and the retrieval of knowledge after spillovers

Research summary: Firms create and capture value through innovation. In technology‐driven firms, there has been an explicit emphasis on appropriability through imitation deterrence and cumulative inventions that build on prior firm innovation. We introduce systematic empirical evidence for a third mechanism of appropriability namely, knowledge retrieval, which is defined as the re‐absorption of previously spilled knowledge. We extend previous studies which consider technological complexity and organizational coupling as predictors of appropriability by examining their impact on knowledge retrieval. We find that technological complexity has a curvilinear relationship with retrieval while organizational coupling has a negative relationship. We discuss the implications of these findings for theories of absorptive capacity, organizational design and appropriability of innovation. Managerial summary: It is a widely held assumption that knowledge should be protected and held tightly within the firm to ensure value creation and value capture. The implicit recognition is that knowledge spillovers, or knowledge leakage, is detrimental to performance. By examining the patterns of citations among patents of 142 semiconductor firms, we study how organizational structure and technological complexity play a role. We find that moderate technological complexity improves appropriability. If imitation deterrence is paramount, then the optimal structure would be a tightly‐coupled organization. In other instances, loosely‐coupled organizations may be superior because they foster internal cumulative innovations and, if spillovers were to occur, they also maximize knowledge retrieval. Our findings suggest that all is not lost when spillovers occur and that firms can continue to benefit in downstream innovations. Copyright © 2015 John Wiley & Sons, Ltd.     

制度环境、技术复杂度与空间溢出的产业间非均衡性

制度环境作为约束区际互动的因素对于经济空间关联具有不可忽视的影响。本文系统地构建了空间溢出影响产业演化的路径体系,探索制度环境导致空间溢出产业间非均衡性的作用机制,以剖析制度影响区际经济关联的微观基础。基于中国地级地区4位数制造业的实证研究表明,地区间会通过“水平关联”“技术关联”与“投入产出关联”三条路径实现空间溢出,但受到制度环境的调节,较差的制度环境会削弱溢出效应。制度环境通过信任机制影响区际互动,对于不同溢出路径具有差异性的调节作用。技术关联和投入产出关联溢出依赖于企业间的密切互动,显著受到制度环境的调节;水平关联溢出并不一定依赖于企业间互动,受制度环境的调节作用较弱。高技术复杂度产业的发展更加依赖于具有密切技术相关性和投入产出关系的企业间协同机制,因而要求优越的制度环境支持,由此,在制度环境影响下,空间溢出在不同技术复杂度的产业间表现出非均衡性。本文结论暗含“产业促进政策悖论”:致力于促进本地发展的政策很可能因为扭曲制度环境反而成为制约发展的因素。中国推进转型发展与区域协同创新需要降低区际经济互动的交易成本,设计和建设规则透明、信息畅通、政策公平的正式制度是重点之一。     

The value of knowledge spillovers in the U.S. semiconductor industry

This paper aims at quantifying the economic value of knowledge spillovers by exploring information contained in patent citations. We estimate a market valuation equation of the U.S. semiconductor firms during the 1980s and 1990s, and find an average value of $0.6 to 1.2 million “R&D-equivalent” dollars for knowledge spillovers embodied in one patent citation. For an average semiconductor firm, such an estimate implies that the total value of knowledge spillovers the firm received during the sample period can be as high as half of its actual total R&D expenditures in the same period. This provides a direct measure of the economic value of social returns or externalities of relevant technological innovations. We also find that the value of knowledge spillovers declines as the size of firm's patent portfolio increases, and that self citations are more valuable than external citations, indicating a significant amount of tacit knowledge or know-how spillovers that occur within the firm.     

Experience and scale and scope economies: trade‐offs and performance in development

This paper examines how knowledge created by firm experience (learning economies) and scale and scope economies affect performance in firms' development activities. The empirical results suggest that each factor has a significant effect on development performance. Moreover, knowledge that results from greater experience within a particular technological area, when combined with knowledge spillovers from greater scope in other technological areas, significantly improves development performance. The results suggest that experience shapes and facilitates firms' abilities to absorb knowledge spillovers. Our empirical findings thus provide a more nuanced examination of the drivers of performance and have implications for the management of firms' development activities.

The impact of innovation intensity,scope, and spillovers on sales growth in Chinese firms

We investigate the relationship between innovation and sales growth of firms in China. Innovation theories suggest firms create the technological knowledge needed to have market impact with their products and drive sales growth in different ways. These include: (1) through firms’ overall innovation intensity, (2) through decisions on innovation scope (depth vs. diversity), and (3) through knowledge spillovers from technological neighbors. Little research exists on how effective these approaches are for emerging market firms in pursuit of growth. To address this, we integrate and test the effects of these different knowledge creation mechanisms using data from Chinese firms over a five-year period. Findings show that innovation intensity and knowledge spillovers positively impact sales growth. We also develop and test a model capturing the non-linear impact of innovation scope. As predicted, we find a U-shaped relationship for depth of innovation and an inverted U-shaped relationship for diversity of innovation.     

Spillovers and the growth of local industries

In this paper we investigate the nature and directions of inter-industry dynamic linkages across Italian manufacturing sectors. We perform a very disaggregated analysis in order to identify, for each 3-digit industry, which composition of industrial activity is more conducive to growth. We find that diversity matters for growth, but each industry needs its own diversity. We provide some evidence of clustering of industries based on dynamic externalities. We find that many spillovers occur within input-output relationships. They often originate in downstream sectors favouring the growth of upstream industries. Lastly, the importance of spillovers does not depend on the technological intensity of the industry.     

Visible parts,invisible whole: Swedish technology student teachers’ conceptions about technological systems

Technological systems are included as a component of national technology curricula and standards for primary and secondary education as well as corresponding teacher education around the world. Little is known, however, of how pupils, students, and teachers conceive of technological systems. In this article we report on a study investigating Swedish technology student teachers’ conceptions of technological systems. The following research question is posed: How do Swedish technology student teachers conceive of technological systems? Data was collected through in-depth qualitative surveys with 26 Swedish technology student teachers. The data was analysed using a hermeneutic method, aided by a theoretical synthesis of established system theories (system significants). The main results of the study are that the technology student teachers expressed diverse conceptions of technological systems, but that on average almost half of them provided answers that were considered as undefined. The parts of the systems that the students understood were mostly the visible parts, either components, devices, or products such as buttons, power lines, hydroelectric plants, or the interface with the software inside a mobile phone. However, the ‘invisible’ or abstract aspects of the technological systems, such as flows of information, energy or matter, or control operations were difficult to understand for the majority of the students. The flow of information was particularly challenging in this regard. The students could identify the input and often the output of the systems, that is, what systems or components do, but the processes that take place within the systems were elusive. Comparing between technological systems also proved difficult for many students. The role of humans was considered important but it was mostly humans as users not as actors on a more systemic level, for example, as system owners, innovators, or politicians. This study confirms previous research in that the students had a basic understanding of structure, input and output of a technological system. Thus, the adult students in this study did not seem to have better understanding of technological systems than school pupils and teachers in previous studies, although this is in line with previous investigations on the general system thinking capabilities of children and adults. The most important implication of this study is that students need to be trained in systems thinking, particularly regarding how components work and connect to each other, flows (especially of information), system dependency, and the human role in technological systems.     

Effects of R & D Spillovers on the Profitability of Firms

This cross-section study of a sample of 278 firms from the COMPUSTAT II database explores the relationship between a firm's profitability and other variables, notably its own R & D capital, knowledge and market spillovers and appropriability. The proxy for knowledge spillovers is based on technological distance. Market spillovers are based on a patent input-output matrix. Both spillover proxies combine information on R & D expenditures and patent counts.The results do not reject the hypothesis that R & D has a direct, positive effect on profitability, especially in industries with effective patent protection. Information spillovers affect profits negatively, market spillovers positively.     

Where Do Breakthroughs Come From? Characteristics of High‐Potential Inventions

Breakthrough technological inventions create the foundation for many innovative opportunities. Through novel scientific fundamentals and unique combinations of knowledge, they form a new basis for technology development and innovation, shifting their industry's mindset about what is feasible and valuable. Prior research has, to date, characteristically taken an organizational‐level perspective on technology breakthroughs, seeking to explain the occurrence of breakthroughs as a function of firm‐level characteristics and processes. This tells us less, however, about the underlying knowledge structures of the technologies themselves. This research is based on the assumption that an examination of the knowledge foundations of high‐potential inventions can enrich our understanding about the underlying features of innovations that transform industries and advance societies. In this manner, we can clarify how certain technologies are advanced and extended, providing the basis for future discoveries. Our analysis focuses on high‐potential patents: those having the highest number of forward citations in a given class. We conduct this analysis on a sample of 298 breakthrough patents and two comparison nonbreakthrough groups in drug and semiconductor classes. Our results show that breakthrough technologies, compared with nonbreakthroughs, are more likely to build on: (1) the past technological developments of others, by backward citing and embodying knowledge from prior discoveries (earlier patents), but not one's own previous developments; (2) the latest technologies, by backward citing recent patents; (3) geographic proximity, evidenced by the fact that the focal patents backward cite patents from one's own country; and (4) greater technological breadth, evidenced by the fact that knowledge captured in the patents encompasses a larger number of technical fields. Based on these results, we frame the occurrence of breakthroughs as involving a process where these significant developments happen early in the progress of a technology, but after some relevant knowledge has accumulated. This reinforces the concept that a learning effect needs to occur before breakthroughs can happen. In addition, our findings suggest that the knowledge underlying breakthroughs is likely to come from other organizations or individuals, rather than the developing entity. They also incorporate broader insights from technological diversity but do not exhibit geographic diversity. Instead, they are associated with geographic proximity, which may better enable knowledge sharing and integration given the reliance on other entities and diverse knowledge.     

The Impact of Local Demand on Innovation in a Global Industry

Localization of knowledge flows has been extensively examined in the literature on innovation. However, almost all previous research has focused on technological knowledge. This study examines why knowledge of demand can also be tacit and localized. We provide a detailed empirical study of the global pharmaceutical industry and find not only that demand is as important as technological knowledge in determining the pattern of innovation in this industry but also that innovation is a locally determined phenomenon. These findings contribute to research regarding determinants of innovations and provide an explanation for geographic patterns of innovation that is distinct from technological knowledge spillovers.

Why firms make unilateral investments specific to other firms: the case of OEM suppliers

This study examines why and under what conditions firms will make unilateral relationship‐specific investments to their transaction partners. We propose that firms are more likely to make such investments when the investment yields positive economic spillover values for other transactions with the same exchange partners as well as for third‐party transactions. We also model two types of positive inter‐project spillover effects that a transaction may generate: knowledge spillovers and reputation spillovers. We find empirical support for our developed theory in the context of Taiwanese suppliers of original equipment manufacturers. Copyright © 2008 John Wiley & Sons, Ltd.     

Organizing for Inbound Open Innovation: How External Consultants and a Dedicated R&D Unit Influence Product Innovation Performance

Firms increasingly acquire technological knowledge from external sources to improve their innovation performance. This strategic approach is known as inbound open innovation. The existing empirical evidence regarding the impact of inbound open innovation on performance, however, is ambiguous. The equivocal results are due to moderating factors that influence a firm's ability to acquire technological knowledge from external sources and to transform it into innovation outputs. This paper focuses on a relevant yet overlooked category of moderating factors: organization of research and development (R&D). It explores two organizational mechanisms: one informal and external‐oriented (involvement of external consultants in R&D activities) and one formalized and internal‐oriented (existence of a dedicated R&D unit), in the acquisition of technological knowledge through R&D outsourcing, a particular contractual form for inbound open innovation. Drawing on a capabilities perspective and using a longitudinal dataset of 841 Spanish manufacturing firms observed over the period 1999–2007, this paper provides a fine‐grained analysis of the moderating effects of the two organizational mechanisms. The involvement of external consultants in R&D activities strengthens the impact of inbound open innovation on innovation performance by increasing marginal benefits of acquiring external technological knowledge through R&D outsourcing. Moreover, it reduces the level of inbound open innovation to which the highest innovation performance corresponds. Instead, the existence of a dedicated R&D unit makes the firm less sensitive to changes in the level of inbound open innovation, by reducing marginal benefits of acquiring external technological knowledge through R&D outsourcing, and increases the level of inbound open innovation to which the highest innovation performance corresponds. The results regarding the role of informal and formalized R&D organizational mechanisms contribute to research on open innovation and absorptive capacity, and also inform managers as to what organizational mechanism is recommended to acquire external technological knowledge, depending on the objectives that the firm pursues.     

How technology teachers understand technological knowledge

Swedish technology teachers’ views of technological knowledge are examined through a written survey and a series of interviews. The study indicates that technology teachers’ understandings of what constitutes technological knowledge and how it is justified vary considerably. The philosophical discussions on the topic are unknown to them. This lack of a proper framework for what constitutes technological knowledge and how it is justified might affect both how curricula are interpreted and how pupils’ knowledge is assessed.     

The role of institutional arbitrage in the search for product innovation: Firm level evidence from Norway

Evolutionary theorizing conceptualizes the discovery of new products as a successful outcome from searching for innovation in which firms combine new and old knowledge and resources. Prior research has shown that the propensity for discovering new products is greatest when firms cross a technological and/or organizational boundary in the search for new knowledge. In this paper, we add a new dimension to this literature: we examine whether, and to what extent, crossing a national boundary, as when firms use knowledge from network partners in foreign countries, influences the likelihood that firms will introduce new products into the market. Drawing on theorizing on institutional arbitrage in the literature on national innovation systems (NIS) and varieties of capitalism (VOC), we propose that companies that cross a national boundary in searching for innovation are significantly more likely to introduce new products. Detailed survey data on firms; data on their network partners, including their location; and regression analysis show that the use of knowledge from actors in foreign NIS has a positive influence on product innovation.

Recent Research in Learning Technological Concepts and Processes

This paper examines recent research in student learning of technological concepts and processes. To explore this area three inter-related aspects are considered; existing concepts of technology, technological knowledge and processes. Different views of technology and technology education are reflected in both research outcomes and curriculum documents. Teacher and student perceptions of technology impact on the way in which technology is undertaken in the classroom. Teacher's perceptions of technology influence what they perceive as being important in learning of technology. student's perceptions of technology and technology education influence what knowledge and skills they operationalise in a technological task and hence affect student technological capability. Technological concepts and processes are often defined in different ways by particular groups. Subject subcultures are strongly held by both teachers and students. The influence of subject subcultures and communities of practice will be discussed in terms of defining and operationalising technological concepts and processes. Technological concepts are not consistently defined in the literature. For students to undertake technological activities, knowledge and processes cannot be divorced. Recent research highlights the problems when processes are emphasised over knowledge. This paper will examine different technological concepts in an attempt to create a critical balance between knowledge and process. Much of the literature in technology education has rightly emphasised definitions, curriculum issues, implementation and teacher training. This paper argues that it is now time to place a great emphasis on in-depth research on student understanding of technological concepts and processes and ways in which these can be enhanced.     

Discerning technological systems related to everyday objects: mapping the variation in pupils’ experience

Understanding technology today implies more than being able to use the technological objects present in our everyday lives. Our society is increasingly integrated with technological systems, of which technological objects, and their function, form a part. Technological literacy in that context implies understanding how knowledge is constituted in technology, and in particular how concrete (objects) and abstract levels (systems) are linked. This article has an educational focus concerning systems in technology education. Using a phenomenographic approach, the study explores pupils’ experiences of technological systems as embedded in four everyday objects. We identify five qualitatively different ways of understanding systems, ranging from a focus on using the particular objects, over-focussing on the function of objects, seeing objects as part of a process, and seeing objects as system components, to understanding objects as embedded in systems. As a conclusion, we suggest an educational strategy for teaching about systems in technology education.     

Knowledge and Values in Technology Education

This paper addresses two closely interrelated issues in Technology Education: knowledge and values. The starting point for the discussion is analysis of the nature of knowledge in technology education. Approaches for theorising knowledge will be analysed in this paper as well as problems associated with them. Three major types of problems are identified: problems with finding an appropriate approach for the analysis of technological knowledge; problems with a technocratic interpretation of technological knowledge for the purpose of its classification; and problems with establishing a consistent approach to distinguish common features of technological knowledge. A model that represents knowledge in technology education and the place of values in it is presented as a way of overcoming the problems specified. The claim is made that understanding of knowledge/values relationships can improve theoretical understanding of how technology education can be constructed.     

R&D networks and innovation: decentralised product development in multinational enterprises

This paper documents the ways in which overseas R&D in MNEs now plays roles in what are innovative new approaches to innovation itself. Networks of laboratories are seen as supporting both the short-term and long-term competitive evolution of the MNE group's globally-effective product innovation.
In terms of the immediate commercial application of new products for global markets it is argued that product development labs work within creative overseas subsidiaries in MNEs. These aim to derive variants of the new product that fully meet the distinctive needs of each key regional market.
Another separate network of decentralised MNE labs carry out precompetitive (basic or applied) research, embodying particular areas of technological comparative advantage of their host countries. This network of labs therefore provides inputs into a centrally-articulated programme whose objective is to provide the basis of the longer-term technological evolution of the MNE, by upgrading the core knowledge from which future generations of innovative products can emerge.     

Research among copycats: R&D,spillovers, and feedback strategies

We study a stochastic dynamic game of process innovation in which firms can initiate and terminate R&D efforts and production at different times. We discern the impact of knowledge spillovers on the investments in existing markets, as well as on the likely structure of newly forming markets, for all possible asymmetries in production costs between firms. While an increase in spillovers may improve the likelihood of a competitive market, it may at the same time reduce the level to which a technology is developed. We show that the effects of spillovers on investments and surpluses crucially depend on the stage of technology development considered. In particular, we show that high spillovers are not necessarily pro-competitive as they can make it harder for the laggard to catch up with the technology leader.
