Selecting balanced portfolios of R&D projects with interdependencies: A Cross-Entropy based methodology

The intensive growth of technology makes firms rely on research and development (R&D) activities in order to adapt to technology changes in an ever-changing and uncertain environment. Due to R&D budget constraints and limited resources, firms are often forced to select a subset of all candidate projects by means of project portfolio selection techniques mitigating the corresponding risks and enhancing the overall value of portfolio. Projects' interdependencies and types were rarely considered in existing models of R&D portfolio selection that may result in selecting wrong projects. This flaw hinders the projects alignment with corporate objectives and strategy and leads to excessive risk and missing the promised values. In this paper, a balanced set of R&D project evaluation criteria was proposed. Next, to construct R&D project portfolio, a 0–1 nonlinear mathematical programming method for balancing portfolio values and risks was proposed, in which research projects' interdependencies, types and other constraints were all considered. Finally, a Cross-Entropy algorithm was developed to solve the proposed model and results were reported. The algorithm proved to be very effective in terms of solution quality and computational time. The proposed algorithm especially suits large scale instances while exact approaches are doomed to fail.     

Are systems of innovation in Eastern Europe efficient?

This paper explores the determinants of productivity in the countries of Eastern Europe (EE) through the perspective of ‘narrow’ and ‘broad’ national systems of innovation (NSI). Based on panel econometrics, it examines the extent to which systems in EE could be considered ‘(in)efficient’. Our results suggest that the EE countries have lower levels of productivity than might be expected given their research and development (R&D), innovation and production capabilities. The inefficiencies of ‘broad’ NSI are compounded by the inefficiencies of ‘narrow’ NSI in terms of generating numbers of science and technology publications and resident patents relative to R&D employment compared to the rest of the world. Our results point to an important distinction between technology and production capability as the drivers of productivity improvements and provide some policy implications.     

Issues in Assessing the Effect of Interindustry R&D Spillovers

This paper aims to clarify three issues concerning the weighting methodol ogy generally used to evaluate interindustry R&D spillovers. These issues concern the likely nature of the spillovers estimated through different types of supporting matrices; the similarity between input–output (IO), technology flows and technological proximity matrices; and the relevance of the assumption that a single matrix can be used for different countries. Data analyses of weighting components show that technology flows matrices are in an intermediate position between IO matrices and technological proximity matrices, but closer to the former. The various IO matrices, as well as the three technological proximity matrices, are very similar to each other. The panel data estimates of the effect of different types of interindustry R&D spillovers on industrial productivity growth in the G7 countries reject the hypotheses that a technology flows matrix can be approximated by an IO matrix and that a single IO matrix can be usedfor different countries. By transitivity, the procedure that comprises using a single technology flow for several countries is not reliable. The international comparison shows that each country benefits from different types of R&D externality. In Japan and, to a lesser extent, in the US, the rate of return to direct R&D is very high and is likely to compensate for relatively weak interindustry R&D spillover effects. In the five other industrialized countries, the reverse observation is true: strong social rates of return to R&D counterbal ance the poor performances of direct R&D.     

Myth or reality? Assessing the moderating role of CEO compensation on the momentum of innovation in R&D

This study researches the influences of CEO compensation on firm behavior to examine the interactive relationship between the behavioral momentum of innovation in R&D and CEO compensation. The models presented in this study are based on evolutionary, institutional, and agency theories to test hypotheses using data from 107 companies in the high-technology sectors in the United States. The results indicate that the pre-succession innovative behavior of these high-technology firms on R&D can positively affect these firms' post-succession innovative behavior towards R&D. That is, positive momentum in R&D innovation prevails in a firm across a change of the CEO. However, for the role of CEO compensation, short- and long-term compensation does not positively moderate this behavioral momentum in R&D. Hence, the moderating impact of short- and long-term CEO compensation to enhance the momentum of innovation in R&D can be romanticized. These findings provide boards of directors with evidence as to how a CEO succession matters to a firm's behavioral momentum in R&D, and whether CEO compensation can be strategized to change a firm's innovation and momentous behavior.     

Technological innovation and industrial organization in the Danish wind industry *

The origin of this article is the paradox that heavy US R&D funding to hi-tech aerospace industry in the seventies and eighties was not able to provide an appropriate industrial technology base in wind technology that could match the wind turbines from the much more low-tech Danish machine industry (agricultural sector), which received very limited public R&D funding. Nevertheless, the Danish manufacturers took the lion's share of the world market in the eighties, in casu the California home market for the American producers. A bottom-up learning based development strategy almost completely outperformed a science based top down development strategy for this re-introduced energy technology (top down failures were also seen in the UK, Denmark, W. Germany). The top-down and bottom-up strategies reflect two very different types of de facto entrepreneurial behaviour and industrial organization.     

R&D,Interindustry and International Technology Spillovers and the Total Factor Productivity Growth of Manufacturing Industries in Canada, 1974-1989

The paper presents new econometric evidence on the relationship between total factor productivity growth and the R&D expenditures of Canadian manufacturing industries in the presence of interindustry and international spillovers of technology. In contrast to studies that presume that international spillovers are incorporated in imports of intermediate and/or capital equipment goods, the present paper assumes that the principal channel of transmission of new technology is foreign direct investment. Three original proxies for international spillovers use information on patenting, the size and the origin of foreign ownership in the host country and the R&D expenditures in the country of origin. The results suggest that the nexus between industry's own R&D expenditures and the TFP growth is significant and positive, especially for the process-related R&D. Domestic interindustry spillovers of new technology have a larger effect on TFP than industry's own R&D expenditures. All three proxies for international technology spillovers are associated positively and significantly with TFP growth. However, international spillovers contribute to TFP growth less than domestic interindustry spillovers and less than own process-related R&D.     

Globalisation,industrial diversification and productivity growth in large European R&D companies

This paper aims to assess the impact of both geographic and industrial diversification of economic activities on the productivity performance of large European R&D Multinational Enterprises (MNEs). Based on the worldwide subsidiaries of these firms, we measure the performance of the firms according to their level of industrial diversification and globalisation that we proxy with the presence and importance of subsidiaries in the EU, North America and Asia–Pacific regions. The sample consists of large R&D firms that represent about 80 % of total European R&D. In general, the results indicate a positive impact from globalisation on firms’ R&D productivity, especially in the US, while a negative impact for industrial diversification is found.     

Input/output ranges and performance: an examination of US machine tool producers

Despite the establishment of high-tech multinational enterprises (MNEs) in Ireland since the late 1950s, the country did not succeed in closing the technological gap with most of its EU counterparts. The weak National System of Innovation (NSI), and in particular low business and government R&D levels, combined with a lack of research and technology linkages between MNEs and indigenous firms, explain these poor results. However, the Shannon region in the West of the country presents some specific institutional characteristics that could theoretically make the region a strong technological enclave. The various actors in the region - i.e. the administrative, financial, political and research institutions, as well as the business organizations - have indeed infused a new type of economic development. After a brief review of the available concepts and models articulated around these actors and their interrelationships, the paper analyses whether the Shannon region, taken as an illustrative example, mirrors a specific economic and technological localized setting. The study is based on a survey of indigenous and foreign firms.     

R&D performance assessment of industrial enterprises in China: A two-stage DEA approach

With the growing expenditure on the R&D activities of industrial enterprises above designated size (IEDSs) in China, it is important to evaluate the R&D efficiency of the Chinese IEDSs. However, few studies about R&D efficiency measurement of Chinese IEDSs have considered the internal structure of the R&D production process. To fill this gap, this paper investigates the R&D performance of IEDSs of 30 sample provinces on China's mainland from 2009 to 2014, based on a two-stage data envelopment analysis (DEA) model. The major findings from the empirical results are shown as follows: (i) serious imbalance exists in the R&D resources among Chinese IEDSs of 30 provinces; (ii) there is a decline in the average overall efficiencies after 2012; (iii) there are great differences regarding the performances of R&D activities among the Chinese IEDSs of 30 provinces; (iv) high attention to the R&D activities or strong scientific research atmosphere may promote the R&D efficiency of Chinese IEDSs; and (v) the IEDSs with the relatively high profitability or high government support in terms of R&D activities have relatively poor performance. Based on these findings, several policy suggestions are proposed for the R&D activities of Chinese IEDSs.     

The R&D location decision of the firm and “creative” regions—a survey

In the flurry of recent concern about and research on high technology firms and economic development, there is relatively little attention paid to the perspective of firms and their location decisions. This paper surveys the literature on the location of R&D facilities and on attempts to establish regions based on innovation and creativity. The locations of R&D facilities are constrained by the labor market for scientists and engineers. The locational needs of the firm revolve around ensuring both that professional labor will be able to be attracted to its R&D locations, and that communication (especially face-to-face communication) will be facilitated. Given these twin concerns, R&D is likely to locate primarily in large urban regions. The corresponding success of regions which hope to become major areas of spin-off and creativity is likewise constrained by the joint preferences of R&D workers, venture capital investors, and high-tech employers.     

What motivates R&D professionals? Evidence from decentralized laboratories in Greece

The challenge for research and development (R&D) professionals management is to meet the corporate objectives for effectiveness, productivity and profitability with the needs of technical employees for motivation, reward and satisfaction. Despite the continuous upgrading of the strategic importance of knowledge and technology, human resource management paid little attention to the distinctive characteristics of those highly educated knowledge workers, especially in an international perspective. Based on a large-scale survey of multinational enterprises' (MNEs') decentralized R&D laboratories in Greece, this paper offers insights on the perceived impact of intrinsic and extrinsic compensation on performance. Focused on three distinctive types of research implemented by MNEs, results record the existence of a multifaceted context of researchers' needs and satisfaction determinants, which is differentiated among the different roles of R&D laboratories. Our findings witness that in an EU peripheral economy, R&D professionals are motivated by extrinsic rewards and mainly by economic compensation.     

How to optimize the allocation of research resources? An empirical study based on output and substitution elasticities of universities in Chinese provincial level

Although significant progress has been made in China's basic research in recent years, there remains a wide gap between research in China and that from developed countries. How to optimize the allocative efficiency of research resources is of great importance for increasing research output. In this paper, using the fixed effect stochastic frontier model based on the translog production function, we estimate output and substitution elasticities of research and development (R&D) inputs at universities in China's provincial level during 2009–2016. We find that the R&D technical efficiency of China's universities, after a rapid growth, has tended to become relatively stable. Improvements of internationalization degree and exogenous R&D capabilities are conducive to promoting R&D technical efficiency, whereas expenditures from government grants inhibit the promotion of R&D technical efficiency; the effects of R&D capital deepening and internet penetration are not evident. The output elasticity of R&D capital is much higher than that of R&D personnel, suggesting that R&D capital is the main driving force of research output. The substitution elasticity between R&D capital and personnel has experienced a change from substitution to complementary since 2014. To realize sustained growth of research output, we should increase R&D input with positive output elasticity or reduce R&D input with negative output elasticity, making the necessary trade-offs according to the substitution relationship between the two R&D inputs.     

Interindustry Technology Flows and Productivity in Finnish Manufacturing

The paper examines the importance of interindustry technology flows in finnish manufacturing in the 1980s and early 1990s. An attempt is made to distinguish between embodied technology flows and spillovers, so clarifying the spillover concept.Embodied technology covers intermediate goods and capital equipment. The embodied technology data that have been used are partly based on input—output analysis, while the spillover estimates presented are based on measures of technological distance based on the industry-specific distributions of R&D expenditures. Econometric analysis of the effects of the various technology inputs on total factor productivity implies that technology embodied in foreign machinery, domestic spillovers and, to some extent, the firms' own R&D have been the most important technology sources on average.     

Imputed Interindustry Technology Flows - A Comparative SMFA Analysis

This paper shows how the pattern of an interindustry R&D flow system can be detected using a Subsystem-MFA (SMFA). The standard subsystem analysis shows the innovation spillovers of the relevant innovative sectors of a country, which are then turned into graphical form so that the sector clustering into this system can be displayed like a 'molecule' of sectors. The analysis uses the recently published input-output tables of the OECD for Germany, Japan and the United States for the beginning, the middle and the end of the 1980s. The analysis uses R&D-expenditures as an innovation-indicatorvector, published also by the OECD. The results show that there are specific patterns of interindustry imputed R&D flows that differ to some extent between the given countries. These differences can be interpreted as being due to the specific economic history of these countries.     

Collaboration in Multi-Partner R&D Projects: The Impact of Partnering Scale and Scope

How can firms design collaboration structures for effective performance in R&D projects that involve multiple partners? To address this question, we examine the theoretical underpinnings of collaboration structures in multi-partner R&D projects—i.e., the scale and the scope of partnering efforts. Partnering scale captures the extent of resource interdependencies between a firm and its partners; partnering scope captures both the breadth and depth of the interdependencies between a firm and its partners. Using primary data from 147 multi-partner R&D projects, we develop and test hypotheses that examine the impact of partnering scale and scope decisions on partnering performance. Results indicate that partnering scale has a curvilinear relationship with partnering performance. That is, intermediate levels of partnering scale are associated with higher partnering performance, compared to low or high levels of partnering scale. However, we also find that the nature of this relationship is moderated by the sub-dimensions of partnering scope. Specifically, increase in partnering breadth appears to magnify the negative effect of partnering scale on performance. In contrast, increase in partnering depth appears to overcome this negative effect, allowing firms to operate at higher levels of partnering scale. Taken together, these results highlight the importance of adopting a comprehensive approach to designing collaboration structures for multi-partner R&D projects.     

Adoption,diffusion, and public R&D

This paper studies the impact of public RD&D (Research, Development, and Demonstrations) on the market penetration of a new government-sponsored technology. First, the technology adoption behavior of a firm under uncertainty is reviewed. Secondly, the diffusion of the new technology in a competitive industry that benefits from learning-by-doing is analyzed. Numerical simulations are conducted to determine the effect that variations in government R&D policies have on the rate and level of market penetration. Productive R&D investments affect thelevel of diffusion and R&D demonstrations therate of diffusion.     

Economic conditions for innovation: Private vs. public sector

The Hicks induced innovation hypothesis states that a price increase of a production factor is a spur to invention. We propose an alternative hypothesis restating that a spur to invention requires not only an increase of one factor but also a decrease of at least one other factor to offset the companies’ cost. We illustrate the need for our alternative hypothesis in a historical example of the industrial revolution in the United Kingdom. Furthermore, we econometrically evaluate both hypotheses in a case study of research and development (R&D) in 29 OECD countries from 2003 to 2017. Specifically, we investigate the dependence of investments to R&D on the economic environment represented by average wages and oil prices using panel regression. We find that our alternative hypothesis is supported for R&D funded and/or performed by business enterprises while the original Hicks hypothesis holds for R&D funded by the government and R&D performed by universities. Our results reflect that the business sector is significantly influenced by market conditions, unlike the government and higher education sectors.     

Determinants of industrial innovation in China: Evidence from its recent economic census

This study examines the sources of technological innovation in Chinese industries using the 2004 economic census data. On the one hand, it analyzes the relationships between patent grants and new product sales. On the other hand, it analyzes the relationships among in-house R&D, technology transfer from foreign and Chinese domestic technology markets, spillover effects of foreign investment, as well as export. The study reveals that in-house R&D has become the most important source for industrial innovation in China. In-house technological efforts are critical for developing original innovations as well as for absorbing the technologies transferred from external agencies. However, neither technologies transferred from foreign countries nor those from the domestic technology market are playing significant roles in China’s industrial innovation. The spillover effect of foreign investment on patent grants is strong and significant, though its impact on new product sales is insignificant. Export shows negative, though insignificant, impact on patent grants, but positive, strong, and significant effects on new product development. Overall, the results of this study demonstrate the critical role of in-house R&D in China’s industrial innovation.     

Assessing the technological innovation efficiency of China's high-tech industries with a two-stage network DEA approach

As significant strategic players in China's economy, high-tech industries need to evaluate and analyze the technological innovation activities from a system point of view to understand and improve their technological innovation efficiency and, thereby, promote their development. Different high-tech industries have different characteristics and thus benefit from different industrial development policies. However, few studies to date have discussed this issue from a systematic perspective. In this study, technological innovation activities are divided into a research and development (R&D) stage and a commercialization stage. A high-tech industrial evaluation framework of technological innovation efficiency based on two-stage network data envelopment analysis (DEA) is constructed with shared inputs, additional intermediate inputs, and free intermediate outputs. Our empirical results indicate that the overall efficiency of most industries is relatively low and the differences between the five high-tech industries (i.e., sub-sectors) we examined are large. The Spearman correlation shows that overall efficiency and R&D efficiency are more correlated than overall efficiency and commercialization efficiency. Additionally, R&D has better average efficiency. The sub-sector with the highest average efficiency is computers and office equipment, and the one with the lowest average efficiency is medicines. These findings indicate the inadequacy but potential for breakthroughs in the evolution of high-tech industries in China. The analysis proves that it is necessary to create different industrial policies to encourage effective progress in certain high-tech industries, and some guidelines for doing so are provided.     

A micro-econometric analysis of the role of R&D spillovers using a nonlinear translog specification

This paper assesses the impact of Research and Development (R&D) spillovers on production for a panel of 1,203 Italian manufacturing firms over the period 1998–2003.The estimations are based on a nonlinear translog production function augmented by a measure of R&D spillovers which combines the geographical distance between firms, the technological similarity within each pair of firms and the technical efficiency of each firm. The estimation method takes into account the endogeneity of regressors and the potential sample selection issue regarding the decision by firms to invest in R&D. Results show that the translog production function is more suitable than the Cobb-Douglas for modelling firm behaviour and that returns to scale are increasing. Moreover, the internal and external stocks of technology exert a significant impact on firms’ production. Finally, it emerges that, for Italian manufacturing firms, R&D capital and R&D spillovers are highly substitutes.
