企业技术知识基础多元度对独立创新与合作创新平衡互补效应的影响

整合独立创新与合作创新的协同作用对企业生存和发展具有重要意义。基于知识基础理论，构建技术知识基础相关与非相关多元度、知识整合能力对企业独立创新和合作创新协同性（互补性与平衡性两个维度）的影响效应模型，利用2009—2018年中国生物制药行业80家企业发明专利数据进行实证检验。结果表明，技术知识基础相关多元度对企业独立创新与合作创新互补性具有正向影响，对两类创新活动平衡性具有负向影响；技术知识基础非相关多元度对独立与合作创新互补性具有倒U型影响，对两类创新活动平衡性具有负向影响。企业知识整合能力负向调节技术知识基础相关多元度对独立创新和合作创新互补性的正向影响，削弱技术知识基础相关多元度与独立创新和合作创新平衡性之间的负向关系。同时，企业知识整合能力在技术知识基础非相关多元度与独立创新和合作创新互补性间起负向调节作用。     

Capitalism, profits and innovation in the new techno-economic paradigm

Innovative profits (of the kind conceptualized by Schumpeter) are today being increasingly created through international corporate networks for technological development. Such profits through innovation are encouraged by newer more flexible organizational forms, and further encouraged (unlike in the conventional perspective on profits and on the incentive to innovate) by knowledge flows between firms. Our empirical evidence, based on US patent data, shows that multinational companies are currently more likely to develop abroad technologies which are less science-based, and less dependent upon tacit knowledge. However, within the science-based industries firms may generate abroad some technologies which are heavily dependent on tacit knowledge, but normally in fields that lie outside their own core technological competencies. We find some evidence of a convergence in corporate technological diversification across large firms, facilitated by the now common spread in the use of information and communication technologies (ICT) as an integrator of formerly separate technological systems. This has led smaller firms to diversify, but giant firms to consolidate activity around those technologies that have become most interrelated.     

The Role of Multinational Corporations and National States in the Globalization of Innovatory Capacity: The European Perspective

The recent ability of multinational corporations (MNCs) to develop integrated technological networks, increasingly motivated within Europe by the further progress of economic integration, is argued to affect and be affected by national technological competitiveness. This paper examines the precise geographical dispersion of technological activity in Europe by the largest MNCs, and the potential impact of those MNCs on the level and structure of the technological capacity of European home and host countries, using data on patents granted to the world largest firms in the US. Since the late 1980s, the majority of the technological activity conducted in foreign-owned research facilities located in Europe, has taken place in affiliates of European-owned companies. This paper examines whether the much higher degree of internationalization of corporate technology in European MNCs than in their US or Japanese counterparts is attributable to cross-border activity within Europe, or extends to European-owned research facilities in the US and Japan. While intra-European activity matters more for Dutch, Belgian and Swedish MNCs (and in the electrical equipment and computing industries), whose strategies are substantially based on corporate European integration, investments in the US are of greater significance for French and Swiss companies, and of the greatest importance for German and British firms (and in the chemical and pharmaceutical industries), representing a more widely 'globalized' technological strategy.

Firms as the source of innovation and growth: the evolution of technological competence

It is argued that the firm is the principal source of innovation and growth, a device for the establishment of technological competence, and for its continued development over time. Markets, products and background knowledge may change quite dramatically over time. Yet as a result of the cumulative nature of learning in the production processes of firms, the profile of corporate technological competence will tend to persist over quite long periods, provided there is institutional continuity. Within the same firm, competence may evolve into related areas, but the firm's technological origins will remain identifiable in its subsequent trajectories. However, if the institution itself changes more dramatically, this technological persistence may be disrupted. Supporting evidence is provided from data on the patenting of 30 large US and European companies, which have been continuously active since the interwar period. The science and the knowledge base, and the composition of products and markets may shift quite radically, but the firm's productive and technological system itself is potentially more stable. The firm provides a vehicle for potential institutional continuity and a device for managing transitions within the economic system.     

Role of home and host country innovation systems in r&d internationalisation: a patent citation analysis

This paper has three novelties. First, we argue that any given R&D facility’s capacity to exploit and/or augment technological competences is a function not just of its own resources, but the efficiency with which it can utilise complementary resources associated with the relevant local innovation system. Just as asset-augmenting activities require proximity to the economic units (and thus the innovation system) from which they seek to learn, asset-exploiting activities draw from the parent’s technological resources as well as from the other assets of the home location’s innovation system. Furthermore, we argue that most firms tend to undertake both asset exploiting and augmenting activities simultaneously. Second, we use patent citation data from the European Patent Office to quantify the relative asset augmenting vs. exploiting character of foreign-located R&D. Third, we do so for European MNEs located in the US, as well as US MNEs located in Europe. Our results indicate that both EU (US) affiliates in the US (EU) rely extensively on home region knowledge sources, although they appear to exploit the host country knowledge base as well.     

Identifying the structure of knowledge networks in the US mobile ecosystems: patent citation analysis

With the emergence of smartphones, the paradigm of the mobile ecosystem has changed rapidly. In particular, global mobile firms focus on technological competition when jostling for market position in recognition of the strategic need to secure a strong mobile platform. In this paper, we analyse the network structure of technological knowledge flows in mobile ecosystems using US patent citation information. We find that two subsectors, platform providers and application and software providers, are at the centre of knowledge exchange activity and play a brokerage role as the key knowledge mediator. Then, we categorise mobile firms into five different groups based on the patterns of their network centrality: knowledge keystone players, knowledge-distributing mediators, knowledge-absorbing mediators, catch-up players, and pure knowledge receivers. The categorisation of firms demonstrates that knowledge flows in the mobile industry converge towards a few leading firms, and such patterns are shaping the mobile ecosystem with respect to technological knowledge. The firms categorised as catch-up players have played a brokerage role within their group, while the firms categorised as knowledge keystone players play a brokerage role across different groups.     

Inter-Firm Technological Cooperation: Effects Of Absorptive Capacity,Firm-Size And Specialization

This paper aims to add evidence on the role played by firms' technological competencies in the determination of their intensity of cooperation with other firms. Using a database composed by patents jointly filcd by two or more firms in the European Patent Office, the paper confronts the hypotheses of complementary or substitutive character of technological cooperation in relation to intra-mural R&D. The results suggest that more technologically and productive specialized firms are more likely to cooperate and find no support for the hypothesis that greater level of R&D expenditure will induce greater reliance on technological cooperation. It is also suggested that firms cooperate with partners that hold cotilplenientary competencies.     

Sectoral Patterns of Interactive Learning: An Empirical Exploration of a Case in a Dutch Region

This paper pursues the development of a theoretical framework that explains interactive learning between innovator firms and external actors in both the knowledge infrastructure and the production chain. The research question is: What kinds of factors explain the interactive learning of innovator firms with distinct external actors? Our theoretical framework extends the resource-based perspective, which is predominant in network theory, with both an activity-based and a structural account of interactive learning. We contend basically that higher technological dynamics induce more complex innovative activities. But, more complex innovative activities increase the probability of internal resource deficits/shortages in the innovator firms. The lower the alignment of the innovative activities with the quality of the internal resource base, the higher the resource deficits/shortages and the more likely the search for complementary resources externally, which increases the likeliness of external relationships. In order to test the generality of our theoretical claims we analyse our models in four sectors with distinct technological dynamics as distinguished by Pavitt. For each sector we explore five models of the level of interactive learning of innovator firms with: (1) the public knowledge infrastructure (difficult to access, demands high internal competencies to utilize scientific knowledge), (2) the production chain (easy to access), (3) their users, (4) their suppliers, (5) their competitors. These analyses allow for a comparison between interactive learning with different external actors and give deeper insights into the differentiated interaction patterns involving innovation. Our findings show that patterns of interactive learning between sectors differ. Some are more resource based and others are more affected by the complexity of innovative activities. Particularly the patterns of interactive learning between, on the one hand, firms and the knowledge infrastructure, and on the other hand of firms with the production chain show important differences.     

International,intra-national and inter-firm knowledge diffusion and technological catch-up: the USA,Japan, Korea and Taiwan in the memory chip industry

Using data on US patent citations, this paper investigates the pattern of international, intranational and interfirm knowledge diffusion in the process of technological catch-up by Japanese, Korean and Taiwanese firms in the memory chip industry. First, regarding international diffusion, this paper finds that the ordering of citations is exactly the same as the order of entry into the industry: Taiwanese firms tend to cite Korean firms, Korean firms tend to cite Japanese firms and Japanese firms tend to cite US firms. Second, the degree of intranational knowledge diffusion is proportional to the level of technological capability or order of entry, although it is also affected by organisational differences among the firms. Third, the difference in patterns of interfirm knowledge reflects difference across organisations, such that big Korean group firms are less oriented toward interfirm knowledge diffusion compared with their Taiwanese small and medium enterprise (SME) counterparts. To explain such difference, the role of government research institutions has been highlighted, especially since the Industrial Technology Research Institute (ITRI) accounts for the lion's share of Taiwanese-held patents and in the spin-offs of many firms in the industry.

Technological districts localized spillovers and productivity growth. The Italian evidence on technological externalities in the core regions

Technological R&D externalities are the effects on the technological capacity of each firm stemming from the complementary and interrelated activities of R&D activities of other firms that operate both in the same industry and in other industries. R&D technological externalities are specially influential at the regional level. Regional proximity enhances the circulation of information, the opportunities for external learning; the scope for capitalizing on potential complementarities among the variety of firms and the different R&D activities being carried out by each firm, and the opportunity for technological networking. The empirical evidence on core regions in Italy in the 1980s confirms that regional clustering of complementary and interrelated R&D activities facilitated the emergence of technological districts. Firms located within technological districts benefited enormously from the R&D technological externalities spilling out from the complementary and interrelated R&D activities of other firms localized in the same area. Consequently, firms localized within technological districts had fast rates of introduction of technological innovations which, in turn, made it possible for total factor productivity levels to be raised with comparatively low levels of intra-muros R&D expenses.     

Properties of knowledge base and firm survival: Evidence from a sample of French manufacturing firms

The paper analyzes the effects of the properties of firms' knowledge base on the survival likelihood of firms. Drawing upon the analysis of the patterns of co-occurrence of technological classes in patent applications, we derive the coherence, variety and cognitive distance indexes, accounting respectively for technological complementarity, differentiation and dissimilarity in the firms' patent portfolios. The results of our analysis are in line with the previous literature, showing that innovation enhances the survival likelihood of firms. In addition, we show that the search strategies at work in the development of firms' knowledge base matter in reducing the likelihood of a failure event. Knowledge coherence and variety appear to be positively related to firms' survival, while cognitive distance exerts a negative effect. We conclude that firms able to exploit the accumulated technological competences have more chances to be successful in competing durably in the market arena, and derive some policy implications concerning the role of public intervention in the orientation of search efforts in local contexts.     

Firms' Technological Trajectories and the Creation of Foreign Subsidiaries

Multinational firms are traditionally considered as firms possessing some technological lead and which are exploiting this proprietary advantage in international markets, but a growing literature has been arguing that multinational firms set up foreign subsidiaries not only as a means to exploit their own technology but also to enrich it. This paper provides some empirical evidence for this. The aim of the paper is to assess the effects of the creation of foreign subsidiaries on firms' technological trajectories.The idea is that by setting up subsidiaries in foreign countries, multinational firms can achieve some form of reverse technology transfer that can be expected to affect their technological trajectories.The empirical investigation uses data from 1992 to 1996 for a sample of 2185 Italian manufacturing firms. Results support the view that the creation of manufacturing subsidiaries has a positive impact on firms' productivity trajectories and this positive impact is greater when subsidiaries are created in regions where knowledge spillovers are expected to be relatively higher, such as the US.     

Appropriation Of Returns From Technological Assets And The Values Of Patents And R&D In Japanese High-Tech Firms †

This paper investigates the extent that technological assets contribute to the value of the firm, using the sample of 90 Japanese firms in pharmaceutical, chemical, and electrical equipment industries. We use the firm's R&D expenditures and the number of patents (in stock) as the measures of its technological assets and show that the relative usefulness of these two measures varies across industries. Particularly, Tobin's q is positively related to the technological assets most strongly in the pharmaceutical industry. It is also most sensitive in this industry to the level of patent stock, coinciding with the view that drug patents are more effective than other patents as a means of appropriating returns from innovation. The communications equipment industry is also characterized by its q's dependence on patent stock. In addition, this industry's q is particularly sensitive to the level of net R&D investment in the most recent year, presumably because of the rapid technological progress in this industry.     

The relationship between a firm's patent quality and its market value — The case of US pharmaceutical industry

This study examined the relationships between corporate market value and four patent quality indicators - relative patent position (RPP), revealed technology advantage (RTA), Herfindahl-Hirschman Index of patents (HHI of patents), and patent citations - in the US pharmaceutical industry. The results showed that RPP and patent citations were positively associated with corporate market value, but HHI of patents was negatively associated with it, while RTA was not significantly related to it. Thus, if pharmaceutical companies want to enhance their market value, they should increase their leading positions in their most important technological fields, cultivate more diversity of technological capabilities, and raise innovative value of their patents. In addition, this study found that market value of pharmaceutical companies with high patent counts was higher than that of pharmaceutical companies with low patent counts, and suggested that pharmaceutical companies with low patent counts should increase RPP in their most technological fields, decrease HHI of patents, or raise patent citations to further enhance their market value. Furthermore, this study developed a classification for the pharmaceutical companies to divide them into four types, and provided some suggestions to them.     

The evolution of the industrial organisation of the production of knowledge

This work elaborates the notion of localised technological knowledge,based upon the distinction between information, competence andknowledge, and analyses the emergence of the new knowledge industry.The evolution of the organisation of knowledge production isanalysed through four stylised modes: scientific entrepreneurship,institutional variety, vertical integration and technologicalcooperation. The new trends towards the growth of knowledge-intensivebusiness service industries are detected and underlined. Theyare considered as the outcome of the institutional formationof a market for knowledge based upon a process of increasingappropriability of localised knowledge based on: the blendingof generic scientific information and competence and growingscope of applicability via computer-communication systems; deverticalisationof research activities from the boundaries of corporations;the specification of a demand for technological competence;and the specialising of independent firms in the productionof technological competence and knowledge.     

R&D,TECHNOLOGY SPILLOVERS AND STOCK PRICES†

Abstract. Theories of endogenous growth suggest that technological progress is driven by firms’ own R&D effort and knowledge spillovers. Using panel data for US firms over the period from 1990 to 1999 this paper tests the influence on stock prices of technological spillovers through firms’ purchase of intermediate products from other firms. The empirical results show that stock prices are significantly positively affected by knowledge spillovers through the input of intermediate products.     

Technology flows between sectors and their impact on large-scale firms

In this article we highlight the importance of technology flows between sectors and their impact on the labour productivity of large-scale corporations. Based on theoretical considerations, we explore technological spillovers between the sectors of an economy. Large-scale corporations usually focus on certain sectors but make use of a wide range of technological knowledge from other sectors. Thereby, technological knowledge built up in sectors by continuous R&D activities does not spill over without bounds but is directed by firms’ absorptive capacities. We use firms’ patent portfolio to empirically calculate the sector affiliation and therewith the firms’ absorptive capacities in order to estimate the impact of technology diffusion on labour productivity. Fortune 500 firms serve as data base.
