The UNFCCC has stated that energy policies and measures to address climate change should be cost-effective to ensure global benefits at the lowest possible cost. To mitigate the bulk of carbon emission from the electricity sector, a large market penetration of renewable energy technologies with as low cost as possible is a key research topic. The energy-related R&D policy in Japan aims to achieve a green economy. In our study, based on this context, we demonstrated how to optimize the timing of public R&D investment within the framework of a bottom-up partial equilibrium model. The developed optimization model represents the Japanese electricity sector and minimizes the total system cost subject to an accumulated carbon emission constraint. Our main research focus is the role of R&D activity, especially in the innovation stage of renewable technologies. We employ a two-factor learning curve and quantify the impact of the learning effect on the dynamic diffusion of major renewable technologies. The study shows a dynamic technology transition in the Japanese electricity sector and the optimized R&D investment schedule for each renewable technology. With the first-best energy policy, an R&D budget of more than 2000 million USD would be allocated to PV in 2050, which corresponds to 45% of the energy-related Japanese R&D budget in 2050. Because some have criticized the uncertainty problems with dynamic simulations and learning models, supplemental sensitivity analyses are included.  相似文献

This paper investigates the impact of firm R&D policies supporting R&D investment and collaboration on company innovation performance. Individual and cooperative R&D investments are considered as intermediate outcomes (input and behavioural additionality, respectively) contributing to the final outcome (probability of product innovation). We use a treatment random coefficient model to estimate the policy additionality on a panel data-set merging the third and the fourth wave of the Italian Community Innovation Survey. Results show a significant and positive policy impact on company propensity to product innovation only for the input additionality and for the interaction between the input and the cooperative additionality. This occurs when company cooperation scores overcome a given threshold, in accordance with the assumption that cooperation entails benefits but also coordination costs.  相似文献

This article evaluates the propensity of firms to apply for R&D public grants, their capacity for obtaining subsides and how these relate to the firm age. This analysis is particularly relevant in understanding why young firms may be more or less successful in their application for public subsidies. Using data from an extensive database of 19,236 firms in Catalonia, we estimate a maximum likelihood probit model with sample selection. Our results show that firm age does not exert a significant direct impact on the application propensity in R&D public call, but younger firms tend to show a larger propensity to receive an R&D subsidy. They also show that firm age exerts a moderating role through different internal resources. They highlight the need to design R&D public policies that explicitly favour applications by young firms to help overcome their obstacles to innovation.  相似文献

In this paper, we examine the differential impact of cooperation with heterogeneous partners on firms' innovation capabilities. We use the number of joint patent applications of Chinese manufacturing firms from 2008 to 2018 to measure cooperation with different types of partners and the number of corporate patents to measure the innovation capability of firms. The results indicate that R&D cooperation with other enterprises, universities, and research institutions all have a significantly positive impact on the innovation capability of enterprises. However, R&D cooperation with universities or research institutions has a higher positive impact on innovation capability than that with other firms. Different internal and external factors moderate the relationship between heterogeneous partners and the innovation capability of firms. Specifically, firms with higher absorptive capacity will benefit more from R&D cooperation with corporate partners. In contrast, in industries with higher market concentration or where firms are at the technological frontier, cooperation with universities will positively impact their innovation capabilities. Further research demonstrates that absorptive capacity has a more positive moderating effect when the cooperation is between firms in the same industry, compared to R&D cooperation between firms in different industries.  相似文献

The paper contributes to an emerging literature that critically questions the degree to which R&D, at the centre of national and transnational innovation policies, results in firm growth. The differences in how innovation affects firm growth is explored for small and large publicly quoted US pharmaceutical firms between 1950 and 2008. We observe that the positive impact of R&D on firm growth is highly conditional upon a combination of firm-specific characteristics such as firm size, patenting and persistence in patenting. For small firms, R&D boosts growth for only a subset of firms: namely, those that patent persistently for a minimum of five years. For large pharmaceutical firms, on the other hand, R&D may have a negative impact on growth; potentially resulting from the low R&D productivity these firms have suffered from since the mid-1990s. These results raise important issues around the R&D and firm growth relationship for small and large firms as well the role of persistence in innovation for boosting firm performance.  相似文献

Abstract

Two distinct risks cast a shadow over the sustainability of the existing energy mix. One is security of supply. The diversification of energy sources – both geographical and technological – could mitigate those risks. The second is environmental. Climate change in particular has raised questions about the sustainability of the current fossil fuel emission-intensive mix.

The government is currently investigating whether current R&D priorities and programmes are adequately focused and resourced to bring on-stream the energy technologies of the future. The future energy scenarios explored in the National Energy Strategy will help deliver a view of where some of the potentials and roadblocks currently lie in respect of new energy technologies. This in turn will guide the development of a roadmap of energy research priorities.

Equally important is gaining a better understanding about the actual distribution of research effort on the energy-related technologies and market deployment of different technologies.

While science, research and innovation in a global and highly competitive marketplace coupled with consumer preferences will be a decisive influence, timely access to new technologies and energy resources is of significant national interest.  相似文献

Government regulations can guide the technological progress, investment in research and development (R&D), and institutional organization of a specific sector. In this context, using patent data, this study aimed to analyze the effectiveness of three laws that pertain to R&D in Brazilian pharmaceutical market for vaccines. The results reveal an increasing international interest in the Brazilian market since the promulgation of the Industrial Property Law. Despite its limitations, this study reveals significant efforts and promising results in Brazil with respect to ensuring that technological and industrial policies and strategies incorporate innovation in vaccine R&D and change the economy's competitive circumstances.  相似文献

Abstract

Each year, the United States invests approximately $495 billion in research and development (R&D) – about a quarter of the total global investment. While the private sector accounts for about 67% of U.S. investment, the Federal government plays a critical role in funding R&D, particularly in areas that address societal needs in which the private sector does not yet have sufficient clear or strong incentive to make the required investments. The Federal government invests approximately $150 billion each year in R&D conducted at Federal laboratories, universities and other research organizations. As Federal R&D investments wind down or are completed, additional work is often still needed to translate the knowledge accrued from that R&D into products and services that will improve lives and provide economic growth. Technology transfer is the process by which existing knowledge, facilities or capabilities developed through R&D are utilised to fulfill public and private need. The transfer of technology from federally-funded R&D to the private sector is crucial to realising the taxpayer’s return on investment in the Federal R&D ecosystem. However, moving innovations from the lab to the market is more than inventing products for people to buy. Technology transfer is about creating jobs and growing the economy; ensuring a strong, secure, and resilient Nation; and improving Americans’ health and environment, fostering the conditions for America to maintain leadership in global innovation.  相似文献

In this study, we attempted to fill a gap that literature has yet to investigate: the impact of global innovation network on industry performance. Based on 3D printing patent data, this paper builds a cooperative innovation network of 34 economies for six years. It represents the network characteristics of each economy through 204 network attribute indicators. The panel data model is used to study the relationship between global innovation network characteristics and the R&D efficiency and the income of the main business of the 3D printing industry. The input and output data for the R&D efficiency of the 3D printing industry is derived from the Wohlers Report. R&D efficiency indicator values are measured by the Malmquist Productivity Index model based on DEA. The research results show that the global innovation network centrality indicators, structural hole indicators and clustering coefficient indicators have significant correlation with industrial performance. The research conclusions will provide theoretical support for various economies to formulate global innovation strategies and policies of 3D printing industry.

Defence R&D continues to account for a very substantial share of many countries' research effort, often retaining or even increasing its role within the national innovation systems. Yet the quantitative analysis of defence research efforts and their impact is impaired by difficulties in defining defence R&D. The article studies these difficulties and focuses on the issue of identifying what constitutes, does not constitute, defence R&D. It finds that the OECD approach of defining defence R&D on the basis of the primary goals of the research is inadequate, particularly in the present context of the growing emphasis on dual-use technologies and research. It then analyses alternative approaches that could provide a more solid grounding for any systematic effort to collect international defence R&D data  相似文献

it is very important to encourage the incubation of new companies for innovative economic growth. Many countries in the world are encouraging “innovation orchards” in the form of government-industry-academia partnership to facilitate the incubation of new technology enterprises. The research focuses on the impact of this partnership between the government, industry, and academia in establishing new R&D institutions on business incubation. Specifically, the research aims to investigate what is the separate effect of the government, enterprises, universities, and public institutions in the establishment of new R&D institutions on enterprise incubation, and the role of cooperation between government-enterprise-academia in the enterprise incubation of new R&D institutions. In empirical tests using data from the 2020 official survey of the Ministry of Science and Technology of China, the results show that for each single cooperator, participation in the establishment of governments, academia has a positive impact on start-ups, while the participation of enterprises has no significant impact. In terms of cooperation, the co-established new R&D institutions are better in business incubation than the single establishment of new R&D institutions. The cooperation between government and academia in the establishment of new R&D institutions has a positive effect on business incubation, and other types of cooperation between government-industry, industry-academia, and government-industry-academia have no significant impact on business incubation. The research conclusion can provide a policy reference for optimizing the holding mode of new R&D institutions.  相似文献

Empirical studies at the individual firm level often find a positive impact of external R&D on innovation. However, external R&D sourcing might produce an impoverishment of the local knowledge base and thus damage innovation production at the regional level. To address this possible fallacy of composition, we first review the various forms of ‘external’ R&D. We then use the French R&D survey to assess the impact of four different ways of transacting or collaborating on R&D: onshore affiliate external R&D, offshore affiliate external R&D, onshore non-affiliate and offshore non-affiliate external R&D. We then estimate knowledge production functions on the 94 metropolitan French NUTS3 regions observed between 1997 and 2008, differentiating internal R&D and these categories of external R&D. We obtain that the impact of onshore non-affiliate external R&D is significantly negative. The other external R&D categories are non-significant and we do not detect any complementarity between internal and external R&D.  相似文献

While the semiconductor industry is still dominated by large vertically integrated firms, fabless firms, which outsource their manufacturing, are gaining market share. Fabless firms are considered to have an advantage in product innovation, as they can focus their innovation efforts on chip design and can benefit from investments in process innovation made by their manufacturing partners. However, there is little empirical evidence of the performance of fabless firms compared to vertically integrated firms. This research empirically examines the relationship between R&D and the financial performance of fabless and vertically integrated firms from 2000 to 2010. Our results show that fabless firms maintain higher gross and net margins, earn a higher return on assets (ROA) and have greater intangible value (Tobin’s q) than vertically integrated firms when controlling for size, capital intensity and R&D ratio (R&D/sales). This supports the argument that fabless firms achieve greater performance by focusing on one part of the innovation process. The relationship of R&D ratio to net margin is negative for the whole sample, suggesting that the industry may be overinvesting in R&D. Notably, the negative relationship is greater for fabless firms, which spend a higher amount of their sales on R&D. The relationship of R&D ratio to ROA and Tobin’s q is negative, and there is no significant difference between fabless and integrated firms. We conclude that fabless firms outperform integrated firms overall, but are somewhat worse in terms of increasing profits and creating value from their R&D investments.  相似文献

Replacing traditional energy sources with renewable energy sources is an effective way to achieve emission reduction targets. Focusing on OECD countries from 1990 to 2018, this study examines the determinants of renewable energy innovation by applying a negative binomial model. There are four main findings: (1) Renewable energy patents show an inverted U-shaped curve, peaking in 2010; solar energy accounts for the largest share of patents; and the US is the largest renewable energy innovator, followed by South Korea and Germany. (2) Renewable electricity installed capacity, share of expenditure on research and development (R&D) of GDP, and implementation of the Kyoto Protocol are all found to promote innovation; by comparison, the proportion of renewable energy power generation of the total electricity generating capacity shows a negative effect. The price of crude oil shows no significant effect due to the offset effect between the European and non-European country groups. (3) Share of R&D expenditure of GDP is confirmed to be the force driving technological progress in the solar, geothermal, and marine sectors, and it plays a more important role in Japan than in the US or Europe. Implementation of the Kyoto Protocol has no significant effect on innovation in European countries. (4) Three institutional factors—namely, the legal system and property rights; regulations; and freedom to trade internationally—are confirmed to be the driving forces, whereas this is not the case for the growth and free circulation of money. Policy implications for the optimization of the renewable energy sector's structure, the enhancement of renewable energy capacity, and the improvement of R&D investment and the institutional environment are proposed. Future research should shed light on a broader sample, using micro-level and socio-technical analysis.  相似文献

The effect of firm size on diverse compositions of R&D expenditures is analysed in detail using firm-level data on the Korean manufacturing sector. On the grounds that each type of R&D activity differs in terms of salability in disembodied form and growth potential due to innovation, a distinction between product vs. process, and new vs. incremental R&D is made. Empirical tests show that the firm size is significantly associated with both the new and incremental R&D. Moreover, firm size is found to be significantly associated with other types of R&D compositions such as the share of R&D devoted to incremental innovation and multidimensional combinations of product, process, new and incremental R&D. These findings support the idea that large firms possess innovative advantages over smaller firms and firm size is an important determinant for firms’ heterogeneous R&D activities. We also discuss the limitations and the implications of the findings.  相似文献

This paper analyses German manufacturing structure in comparison with other EU member states. The paper analyses trends in R&D expenditure and export market shares in the OECD countries, discussing how differences between national institutional frameworks may impact on the innovation strategies that domestic firms follow. It has recently been argued that there is an ‘innovation crisis’ within Germany. The available evidence shows that although Germany is maintaining an overall comparative advantage in R&D intensive industries, this is no longer the case in very high-technology industries.  相似文献

This paper analyses the determinants of R&D offshoring of Spanish firms using information from the Panel of Technological Innovation. We find that being an exporter, international technological cooperation, continuous R&D engagement, applying for patents, being a foreign subsidiary, and firm size are factors that positively affect the decision to offshore R&D. In addition, we find that a lack of financing is an obstacle relatively more important for independent firms than for firms that belong to business groups. For these latter, we also obtain that the factors that influence the decision to offshore R&D differ depending on whether the firm purchases the R&D services within the group or through the market: a higher degree of importance assigned to internal sources of information for innovation as compared to market sources increases (decreases) the probability of R&D offshoring only through the group (market).  相似文献

Despite dependence on foreign oil that keeps countries like the US embroiled in the Middle East, and amid fears of global warming, research and development (R&D) funding for energy technologies has declined significantly during the last two decades throughout the industrial world. Investments in energy technology R&D, and in associated human and institutional capacity, are fundamental to our ability to respond to changing economic, energy, and environmental needs.Although there has been a recent wave of interest in R&D policy in general, and energy R&D in particular, this has not been translated into the needed increases in funding. In most OECD (Organization for Economic Co-operation and Development) member countries, government energy technology R&D budgets have been declining significantly in real terms since the early 1980s. The trends are particularly troubling given the pressing need to develop and utilize the clean energy and low carbon fossil-fuel energy technologies that will be critical in meeting our future energy needs, while addressing the local and global environmental problems we are facing.  相似文献

Future political priorities for science and technology (S&T) policy formulation usually rest on a rather simplistic interpretation of past events. This can lead to serious errors and distortions and can negatively affect the innovation system. In this article we try to highlight the riskiness involved in policy making based on traditional R&D indicators and trends. We would emphasise that this approach does not take account of structural aspects crucial for the analysis of the innovation system. We examine the implications for science, technical and human resources policies of the political challenge of R&D convergence in a peripheral EU region. Three scenarios are developed based on application of the same criteria to the trends observed in traditional R&D input indicators.  相似文献

This paper studies how large State-owned enterprises (SOEs) in China are approaching the technological innovation frontier and contributes to the literature on technological catching up and leapfrogging by identifying three models or strategies of approaching the innovation frontier. In addition to the well-recognised technology transfer based strategy, pursuing emerging technologies and reinventing mature technology could also be effective, with reinventing mature technology as the most important strategy. The paper also finds that strong internal R&D capability, rather than manufacturing capability as suggested by the extant literature, is the basis of all three models. This also implies that making big organisational transformations such as changing a technology transfer centred R&D function to a proprietary technology development centred R&D function, changing a manufacturing centred culture to an innovation centred culture, and reshaping the innovation network, is an important precondition to approach the innovation frontier.  相似文献
