Based on the critical case of ABB, this paper questions the relevance of using patents with multiple inventors from different countries (“cross-country patents”) as an indicator of international R&D collaboration. The study shows that less than half of ABB's cross-country patents are the result of international R&D collaboration as described by one of the more inclusive definitions found in previous literature. Only a third of the patents are the result of joint R&D activities between different MNC subsidiaries or firms. We also discuss the implications of our study for the assignment of patents to countries based on inventor addresses. 相似文献

This paper presents a data envelopment analysis (DEA)/Malmquist index methodology for measuring the change in R&D efficiency at both firm and industry levels. Letting each of ten firms in each year be a separate decision-making unit, and employing one input and three outputs in a DEA case of R&D activity input-output lag, we measure “total factor R&D efficiency” change of Japanese pharmaceutical firms for decade 1983-1992 as defined by the period of R&D input. Decomposing Malmquist index into catch-up and frontier shift components and using “cumulative indices” proposed in this study, we evaluate R&D efficiency change for each firm and empirically show that R&D efficiency of Japanese pharmaceutical industry has almost monotonically gotten worse throughout the study decade. 相似文献

In recent decades, with the rapid development of the knowledge economy and science, countries have embraced technical innovation and have gradually increased investment in research and development (R&D). A vast literature indicates that the relationship between R&D and firm performance is highly complex. The evidence suggests that R&D positively influences firm performance, yet findings on the process by which this happens are mixed. Rigorous analyses are required on how R&D investments affect energy consumption. This study explores the impact of R&D investment on the performance and energy consumption of 476 firms in Ethiopia by employing a combination of fixed-effect, propensity score matching, and endogenous treatment effect estimation methods. The empirical results reveal that investment in R&D positively influences both innovation and long-term financial performance but negatively impacts short-term financial performance and energy consumption. The results also show that the impacts of R&D activities vary significantly across different categories of firms, confirming that heterogeneity may be an issue among the firms considered. The results also indicate that the availability of credit is a more important moderating factor in the relationship between R&D investment and firm performance than the legal system is. These results have important implications for firms with growing R&D operations, especially those in developing countries such as Ethiopia. Ethiopian firms should invest more in R&D activities, such as in fundamental and applied research, to improve performance and enhance competitiveness. 相似文献

This paper examines the relationship between university research and development (R&D) activities and the Bayh-Dole Act. This act made it much easier for universities to obtain patents from research funded by the federal government and may have provided universities with an incentive to alter their R&D activities. The Act may provide an incentive to reduce basic research (which does not generate licensing fees) and increase applied research (which does generate patents and licensing fees). In addition, industry might be more willing to fund university R&D projects since the results would now be easier to patent. This paper differs from the existing literature which uses patent data (a measure of research output) by using research and development data (a measure of inventive input) to examine the effect of the Act. 相似文献

This paper presents findings of a study that discloses key features of the Dutch R&D network in the area of catalysis, a sub-domain of industrial-relevant chemistry. The input comprises empirical data on collaborative research publications, informal network ties, and formal R&D linkages. The study aimed at identifying all public and private sector research organisations involved in the network, characterising their R&D output in terms of international scientific papers and patents, and describing and analysing relational and positional dimensions of their interorganisational network. The results provide an overview of Dutch activity within the worldwide cognitive landscape of catalysis R&D — from both a scientific and technological perspective. The interorganisational relationships reveal a strong and integrated network comprising many universities, public research labs, and private enterprises. The results of a mail survey held among academic and industrial researchers who are active within the network not only corroborate these empirical findings, but also elicited relevant criticisms concerning the efficiency and effectiveness of the network, and provided useful suggestions for its improvement. The paper concludes by looking at the benefits of this methodology, which links external quantitative information and qualitative expert opinions, as an analytical tool for government S&T policy and R&D management purposes. 相似文献

We analyse 446 location decisions of R&D activities by multinational firms incorporated in the European Union over 1999–2006. Our results suggest that on average, the location probability of a representative R&D foreign affiliate increased with agglomeration economies from foreign R&D activities, human capital, proximity to centres of research excellence and the research and innovation capacity of the region. Further, our evidence suggests that in comparison to European multinational firms, the effects of patents intensity and proximity to centres of research excellence were stronger in the case of North American multinational firms. While government R&D expenditure intensity increased the probability of location of R&D activities by European multinational firms in the region, it did not have a significant effect on the probability of location of R&D activities by North American multinational firms. 相似文献

This paper addresses the question of national differences as regard the number of triadic patents applied for by inventors from several OECD countries. The key idea is to determine whether such differences should be attributed to differences in R&D expenditures or rather to some other reasons, mainly institutional or behavioural ones. With this aim in view, both a macro-economic analysis, based on aggregate data for triadic patent counts and R&D expenditures and a micro-economic analysis based on firms’ data from three selected sectors are performed. In both cases, the methodological focus is made on the introduction, the definition and the estimation of a national index of relative efficiency in standard count data models. The main empirical findings are that there is a strong heterogeneity in terms of performance among European countries and a strong intra-country heterogeneity among sectors. This suggests that, in the field of innovation policies, there is a need for “tailored” solutions reflecting the specificities of each innovation system. Moreover, we show that European countries over-perform the United States in some high-tech sectors where the leadership of American firms is traditionally alleged, whereas European firms fail to keep up in more traditional sectors. 相似文献

This paper aims to analyse the risk of intellectual property (IP) infringements by competitors from abroad and in particular to consider whether this risk is higher for international innovating firms. We distinguish three different types of IP infringements from abroad: the usage of firms’ technical inventions, product piracy, and copying of corporate names and designs. Our analysis rests on the German data from the Europe-wide Community Innovation Survey (CIS). We use a unique data set of about 900 observations, which are retrieved from two survey waves. While the earlier wave contains information about international and domestic innovation activities, the later wave reports IP infringements. In a second analysis, the likelihood of infringements from innovation host countries and no-innovation host countries abroad is examined. Before the empirical analysis, an exploratory study was carried out in China with interviews of German firms with innovation activities in China and with a legal advisor for small and medium-sized German enterprises. The results show that firms with international R&D activities are increasing their chances of losing technological knowledge to their local competitors abroad. R&D activities in countries with weak intellectual property rights increase the risk for all types of IP infringements compared to domestic R&D activities. Infringements by competitors from the host country are driven by the production of new produces in this country. Export intensity is the major driver of infringements from no-innovation host countries. R&D activities in China and North America also increase the risk of an infringement. However, firms that innovate only in their home country experience significantly more product piracy cases than international innovating firms. 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

The scope of this paper is to report new empirical evidence on the determinants of R&D co-operation. Indeed, the literature on the capabilities of firms emphasises the role of knowledge in the performance and evolution of firms who use knowledge developed in others to build their own knowledge capital. R&D co-operation between firms is one of the many strategies by which this knowledge may be transmitted. Several theoretical models have stressed that R&D co-operation is more likely when the level of spillovers is high. While this supposition is used in many theoretical models, it has rarely been tested before. Our results do not lend strong support to this intuition. Indeed, our spillover variables (national pure spillovers, national rent spillovers and imports of machine tools), which were supposed to match the theoretical notion of spillovers used in these theoretical models have a positive but not a significant role when explaining R&D co-operation. The R&D co-operation increases with size and with R&D intensity, but not with market share. It also increases with the budget spent on paying license fees and on acquiring patents and labour from foreign firms. In this study, we also analyse the determinants of innovation. In more precise terms, we compare the effects of R&D co-operation to those played by traditional internal factors and those exerted by external, pure and rent spillovers on the innovation capacity of the firms. Our results show that the commercial success of innovations of French firms depends mainly on size, market share, R&D intensity and human capital. Inward FDI from industrialised countries exerts a positive and significant effect. The finding highlights the important role of the absorptive capacity of firms. Spillover measurements, such as the acquisition of machine tools, foreign patents, licenses, and technological opportunities have a positive impact on innovation. 相似文献

This paper presents a new communication-economic network model to predict the allocation of R&D activities in MNCs. While traditional models examine the influencing factors of R&D internationalization separately for each country and come to a one-dimensional result, this multi-dimensional approach integrates the influencing factors in a way that allows to identify an efficient configuration of the entire R&D subsystem in many countries at a time. It captures the information flows and employs a genetic algorithm to find a dispersion of R&D activities in which the problems of international communication have the least negative impact. The model is tested with data from seven MNCs covering a range of 48 countries as potential R&D locations. 相似文献

In the 1980s, Canadian industrial R&D abroad has grown substantially. In 1995, R&D expenditures by Canadian affiliates, only in the United States, represented some US$1.4 billion and employed some 6300 persons. Nearly 60 Canadian-owned and -controlled corporations conduct overseas R&D, mostly in the US, Western Europe, Japan, and Australia. Canadian corporations are performing commercial R&D abroad in order to support their manufacturing subsidiaries and to come closer to customers and markets. A secondary motivation is to hire skilled personnel, monitor foreign technological development and increase the inflow of new ideas into the corporation. They also chose friendly socio-political environments from a regulatory point of view. Technology transfer and adaptation to local markets is also an important mission of the foreign R&D establishment. Foreign R&D activities of Canadian firms are fairly decentralized and autonomous. Most of the foreign subsidiaries undertook R&D abroad before they were acquired by the Canadian corporation; also the number of Canadian managers was reduced and the R&D projects were usually decided in the affiliate. Three main types of expatriate R&D were found: a majority of the subsidiaries were producing goods in the same or related industries as in Canada (such as machines, transportation equipment or housing equipment). A second group of firms were vertically integrated firms, that conducted process research in Canada and advanced materials and final products research abroad, closer to the markets for this type of goods; they were active in the chemical and metal industries. Only one truly global corporation was found, with an international division of labor among its many foreign laboratories. The degree of autonomy varied across the three types of expatriate R&D units. In the last 10 years, the internationalization of industrial research and development has increased very rapidly. Foreign-affiliated corporations operating in the United States represented some 9.3% of all company-funded R&D in that country in 1987, and close to 18% in 1995 (Dalton and Serapio, in this issue). Similarly, foreign R&D expenditures by US-affiliated companies abroad have more than tripled. Canadian industrial R&D abroad has grown at a similar pace. It now includes over 100 research facilities owned by some 60 Canadian corporations, with subsidiaries in the United States, western Europe, Japan, Australia, and several developing countries (China, Brazil, India, Mexico, and Turkey). However, little is known about the characteristics of this foreign R&D: missions, managerial practices, budgets or innovative activity. This study is the first to present original data from a survey of these facilities, complemented by secondary material from annual reports and the financial and technical press. It follows a previous study of Canadian patents abroad, which concluded that diversification into related activities was the overseas strategy of Canadian multinational corporations (MNCs) with foreign R&D activities [Niosi, J., 1997. The globalization of Canadian R&D, Management International Review 37 (4) (in print).]. The first section of this paper presents (1) a short summary of some relevant literature on the management of foreign R&D, (2) the design of the study, (3) the results, and (4) a comparison of theories with Canadian data. It offers conclusions about the existence of three distinctive types of internationalization in Canadian R&D, each with different strategies and outcomes. 相似文献

Stronger protection of patent rights is thought to spur innovation through securing returns to R&D investments. Those investments must be financed, however, suggesting that the responsiveness of R&D to patent reforms varies with financial development levels. We examine the joint impact of domestic and international financial-market development and patent protection on R&D intensities in 22 manufacturing industries in 20 OECD countries for the period 1990-2009. We show that stronger patent rights increase R&D intensities in patent-intensive industries, accounting for the need for external financing and the amount of tangible assets. The primary impact varies across types of financial development: patent protection raises R&D in high-patent industries where countries have more limited equity and credit markets. In contrast, in countries with more developed bond markets industry R&D is more sensitive to patent rights. Interestingly, patent rights in countries that are more exposed to foreign direct investment increase R&D intensities at all levels of financial development. 相似文献

This paper analyses market valuations of UK companies using a new data set of their R&D and IP activities (1989-2002). In contrast to previous studies, the analysis is conducted at the sectoral-level, where the sectors are based on the technological classification originating from Pavitt [Pavitt, K., 1984. Sectoral patterns of technical change. Research Policy 13, 343-373]. The first main result is that the valuation of R&D varies substantially across these sectors. Another important result is that, on average, firms that receive only UK patents tend to have no significant market premium. In direct contrast, patenting through the European Patent Office does raise market value, as does the registration of trade marks in the UK for most sectors. To explore these variations the paper links competitive conditions with the market valuation of innovation. Using profit persistence as a measure of competitive pressure, we find that the sectors that are the most competitive have the lowest market valuation of R&D. Furthermore, within the most competitive sector (‘science based’ manufacturing), firms with larger market shares (an inverse indicator of competitive pressure) also have higher R&D valuations, as well as some positive return to UK patents. We conclude that this evidence supports Schumpeter by finding higher returns to innovation in less than fully competitive markets and contradicts Arrow [Arrow, K., 1962. Economic welfare and the allocation of resources for invention. In: Nelson, R. (Ed.), The Rate and Direction of Inventive Activity. Princeton University Press, Princeton], who argued that, with the existence of IP rights, competitive market structure provides higher incentives to innovate. 相似文献

Research and development (R&D) investment activity plays a crucial role in developing high-tech industries. In recent decades, China has made sustained investments in its domestic high-tech industries, with the goal of increasing their productivity. This paper investigates the effect of this investment on relative R&D efficiency across China's high-tech sectors. Data Envelopment Analysis (DEA) was used to generate quantitative indices for sector comparisons. The analysis of this study indicates that overall R&D investment efficiency did not increase from 1998 to 2009, despite R&D expenditure increasing by 2188%. Over the same period, most sectors suffered from decreasing returns to scale (DRS), presumably also reflecting the inefficient R&D investment. Most of the sectors showed significant fluctuation on R&D investment efficiency. This research result indicates that the problem of China's high-tech industry may be from the inefficiency of its technology commercialization processes, and therefore represents a critical parameter for policy makers and managers. 相似文献

Research and development (R&D) is often essential for firms’ profitability and growth. At the same time, R&D is long-term and risky. We show that innovation activities lead to information ambiguity about the future value of firms’ assets. This effect appears to be more pronounced for small and less reputed firms. Information ambiguity further lowers firms’ market value and, in particular, the market value of innovative assets. We further show that high quality patents mitigate the negative effect of information ambiguity to some extent. 相似文献

This paper purports to study the contribution of R&D at home and abroad to the firm’s inventive activity, using a sample of 137 Japanese multinationals. The empirical analysis relates the number of inventions in Japan and that in the US, as measured by the number of patents issued by the USPTO, to the parent’s R&D, the US subsidiaries’ R&D, the presence of R&D in Europe, the firm’s experience in the US, entry mode, and industry dummies. In addition, to study the subsidiary’s role in sourcing local technological knowledge, we construct indices of local technological strength of the state in which the subsidiary is located. The results, most importantly, indicate that these indices positively contribute to inventions at home and in the US among Type R firms, whose R&D subsidiaries mainly aim to research, suggesting that knowledge sourcing is an important function of these subsidiaries and locational choice is important for this purpose. These results do not hold among Type S firms, whose R&D subsidiaries mainly aim to support local manufacturing and sales activities. 相似文献

The standard empirical framework for analysing the R&D-patents relationship is widened both by examining the different role of in-house and contracted R&D in the innovative performance of firms, and by considering patents and utility models counts as measures of innovation output. Patents and utility models are considered to approximate for significant and incremental innovations, respectively. Applying count data econometrics to a panel data set of Spanish manufacturing firms surveyed in the period 1990-1996, a transcendental production function is estimated, which allows for non-constant elasticities of the R&D inputs. The results indicate that significant innovations are mainly gestated in-house, whereas contracted R&D seems more orientated towards innovations of incremental nature. 相似文献
