We introduce and explore a general equilibrium model with R&D-driven endogenous growth, whose antecedents are the models of Romer (1990) [Romer, P.M., 1990. Endogenous technological change. Journal of Political Economy, 98, S71-102] and Grossman and Helpman (1991) [Grossman, G.M., Helpman E., 1991. Innovation and Growth in the Global Economy, The MIT Press, Cambridge]. Utilizing evidence from recent econometric studies on sources of growth, the model also accounts explicitly for cross-border technological spillovers. The model is specified and calibrated to data from Japan, and is solved to obtain both the transitional and the steady-state equilibria. We explore the effects of selective trade and R&D promotion policies on long-run growth and social welfare. The model results suggest that while a strategic trade policy has little effect on re-allocating resources into domestic R&D activities, it can significantly affect the cross-border spillovers of technological knowledge, which, in turn, stimulates growth. We find that trade liberalization may cause the growth rate to fall and lead to a loss of social welfare in the long-run, although it improves welfare in the short-run. R&D promotion policies stimulate growth by inducing private agents to allocate more resources to domestic R&D, as well as to take greater advantage of global R&D spillovers. Here, we find significantly high growth effects together with sizable gains in social welfare at low incidence to tax payers.  相似文献

Following Jones and Williams [Jones, C.I., Williams, J., 2000. Too much of a good thing? The economics of investment in R&D. Journal of Economic Growth vol. 5 (no. 1), 65–85], we assume that R&D is simultaneously subject to positive and to negative external effects (e.g., the non-rival nature of technology conflicts with congestion externalities). This observation allows to conceive an economy where two R&D sectors evolve without departing significantly from each other in terms of their productive results (society tends to penalize imbalances in technical progress, making negative external effects to appear associated to a sector when this outstands relatively to the other sector; the second sector, in turn, will be subject to positive externalities that reflect a catching up effect). The proposed framework, when associated to a growth setup, is able to replicate the existence of endogenous fluctuations and, therefore, it intends to be a contribution to the literature on endogenous business cycles.  相似文献

In this article we examine how R&D networking affects an organization's innovative output. Using empirical data on 419 research organizations in transgene plant research over a 20-year period, we test several hypotheses relating their sociometric position in an R&D network to their innovative output. Attention is paid to the relative importance of in-house versus collaborative research. Least squares dummy variable models are used to analyze cross-sectional data across different time periods. The results show that (1) an organization's “network embeddedness” positively influences its innovative output; whereas (2) involvement in collaborative R&D has a curvilinear effect on innovative performance.  相似文献

This paper develops an extended version of the quality-adder model by allowing for heterogeneous markets. Based on this model, it presents an empirical analysis of innovation-based growth at the market level using a technometric measurement concept. It can be shown that a growth-promoting effect due to technological progress in a particular single year is observed after between 2 and up to 7 years. This is true not only for highly innovative markets but also for those in which fewer R&D resources are invested.  相似文献

This paper compares the positive and normative implications of two alternative measures to promote R&D-based growth: R&D subsidies to firms and publicly provided education targeted to the development of science and engineering (S&E) skills. The model accounts for the specificity of S&E skills, where individuals with heterogeneous ability choose their type of education. Although intertemporal knowledge spillovers are the only R&D externality, the analysis suggests that R&D subsidies may be detrimental to both productivity growth and welfare. Moreover, they raise earnings inequality. In contrast to R&D subsidies, publicly provided education targeted to S&E skills are found to be unambiguously growth-promoting and neutral with respect to the earnings distribution.  相似文献

The aim of this article is to analyze the interaction between regional R&D productivity and the investment strategies of multinational enterprises. The discussion is based on the hypothesis that R&D investments cause a reduction in the production costs and an increase in firms’ market share; furthermore, R&D costs may be affected by national industrial policies. Supposing the existence of asymmetries in local research productivity, necessary and sufficient conditions for a geographical diversification of resources have been found. Suggestions with respect to the optimal allocation of R&D investment are finally derived.  相似文献

We explore how innovation incentives in a small, open economy should be designed in order to achieve the highest welfare and growth. The computable general equilibrium model we develop for the purpose allows for research and development (R&D)-driven endogenous technological change embodied in varieties of capital. We study policy alternatives targeted towards R&D, capital varieties formation, and domestic investments in capital varieties. Subsidising domestic investments, thereby excluding stimuli to world market deliveries, generates less R&D, capital formation, economic growth, and welfare than do the other alternatives, reflecting that the domestic market for capital varieties is limited. In spite of breeding stronger economic growth, a higher number of patents, and a higher share of R&D in total production, direct R&D support generates slightly less welfare than subsidising formation of capital varieties. The costs in terms of welfare relates to a lower production within each variety firm, which in presence of mark-up pricing results in efficiency losses.  相似文献

This paper investigates the link between trade and environment by exploring the effects of green tariffs on innovation, location of production and the environment. It shows that tariffs levied on polluting goods could result in less world pollution than global harmonization of environmental standards by inducing more pollution-abatement R&D effort and generating lower unit emissions from production. Specifically, green tariffs reduce pollution by (1) shifting production to the region where environmental standards are respected, (2) inducing the firm in the clean country to engage in more abatement R&D by granting it a higher market power/share in its home market, (3) instigating green R&D investment by deterring delocation. When these outweigh the R&D-creating effect of environmental harmonization in the dirty country, green tariffs bring about a cleaner environment.  相似文献

In this paper we investigate the comovements between the R&D intensity of private investment and GDP growth in different European Union (EU) areas over the period 1999–2014. Our empirical analysis shows that only core countries display a common countercyclical mechanism leading to an increased intensity of R&D over prolonged downturns. The lack of an effective countercyclical pattern of R&D intensity over the evolution of GDP growth in periphery countries makes this area highly vulnerable to persistent recessions, with potentially harmful consequences for long‐term growth. For recent EU members the evidence of acyclicality should be evaluated in the light of the catching‐up process still at work in this area. Our analysis suggests that any successful EU innovation policy should not disregard the potential divergence in R&D performance due to the dispersion of the countercyclical properties of the investment intensity in productivity enhancing activities in the different EU areas.  相似文献

The aim of this paper is to investigate the relationship between R&D expenditure and investment in machinery and equipment in order to test for causality. New growth theory emphasises the role of R&D in creating blueprints needed to produce new capital goods implicitly assuming causality running from R&D to investment. Other recent studies using firm level data have investigated the relationship between innovative activity and investment in fixed capital. In this paper we use aggregate data from the US economy on R&D expenditure in the industrial sector and aggregate investment in machinery and equipment. Standard Granger causality tests, together with the Hsiao version, are then performed, showing that causality runs from R&D to investment. In addition we perform a cointegration analysis allowing a test of possible long-run feedbacks. This dynamic representation shows that any feedback between investment and R&D is only significant in the long run.  相似文献

This paper presents evidence about how research and development (R&D) expenditures affect corporate cash holdings in European country groups that differ in their innovation capacity. In theory, one can expect intangible investments such as R&D to result in higher cash stocks than fixed investments, particularly because intangible capital is less suitable as collateral for obtaining external funds. The relationship can be expected to be particularly strong in innovative countries. These countries carry out a relatively high proportion of cutting-edge R&D, which tends to be particularly risky and may be associated with substantial gestation lags before becoming productive. These features tend to increase firms' precautionary cash holdings. To investigate this issue in a European context, we examine different groups of countries that are clustered based on differences in their innovative capacity. Our estimation results confirm a positive relation between changes in R&D investment and changes in cash holdings, whereas changes in fixed investment do not appear to be related to changes in cash positions. The impact of changes in R&D on cash tends to be higher for country groups characterized by a high level of innovative capacity than for countries with moderate levels of innovative capacity. However, the differences across country groups are less pronounced than expected.  相似文献

We introduce an external effect of existing technologies in human capital accumulation in an endogenous growth model and describe its steady-state and transition. We numerically solve the model to compare the quantitative effects of R&D policy with the quantitative effects of human capital policy in wealth and welfare. Although R&D subsidies have now an overall positive effect on growth, wealth and welfare, the calibration exercise shows that for plausible values for the parameters, human capital policy is simultaneously the most income and welfare-improving and the less expensive to the government.  相似文献

The paper addresses the issue as to whether the Italian scientific and technological system can achieve the Barcelona targets set by the heads of state and government (3% of GDP devoted to R&D by the year 2010) and by the R&D guidelines set by the Italian Ministry for Education, University, and Research (MIUR) (to achieve the level of 1.75% of the ratio in the year 2006).The projections built in the paper show that such objectives are well beyond Italy's potential, and that according to a “natura non facit saltus” (NNFS) projection, the country will be able to raise the ratio from 1.04% in 2002 to 1.55% in 2010. Such projection rests on rather optimistic assumptions: higher priority attached to R&D in the government budget, an increasing propensity of firms to invest their value added in R&D, and an increase of researchers' salaries.The difficulty to achieve the objectives set at the European and national level is due to the low starting point, to the lack of additional investment from 2001 to 2003, and to structural factors such as insufficient supply of qualified human resources, the small size of high-tech industry, and constraints imposed by the reduction of public spending.The attainment of R&D policy objectives is more and more dependent on education, industrial, and public budget policies; the issue of a thorough review of the governance of the whole S&T system at the national level is therefore raised. The situation is accentuated by the fact that decisions taken at national level are conditioned by the European union (through the Framework Program, the regulations regarding state aid to firms, etc.) by multinational enterprises, which operate on a global scale, and by regions in the framework of their autonomy.  相似文献

This paper addresses the question of how technology assessment (TA) can be best integrated in the managment of R&D both at the laboratory and the policy level. The main objective is to present a conceptual framework to situate and evaluate the actual and possible TA infrastructure in Europe. The paper consists of three distinct sections. In section one, the concept and practice of TA are briefly introduced with an emphasis on their actual institutionalizations in Europe. Section two presents a conceptual framework of R&D managment at four levels: the R&D environment, the R&D institution, the R&D process, and the R&D project. The relationship between TA and R&D management is explored for each of the four levels. Finally, in section three the concept of and motives for TA integrated within the laboratory work of scientists and engineers are presented. The basic argument of this paper is that by promoting the integration of TA in R&D managment practices, a significant contribution can be made to (1) increasing the cost-efficiency of research and (2) increase the social responsiblity of scientists. The authors therefore draw up a conceptual framework for the development of R&D-integrated TA practices called Integrated Technology Assessment (ITA).  相似文献

It has been shown under the assumption of linear R&D technology that a government subsidy to imitative (innovative) R&D decreases (increases) imitative effort but increases (decreases) innovative effort, and that strengthening the enforcement of patent laws leads to a decrease in innovative R&D but to an increase in imitative R&D. By replacing the linear R&D technology with a sufficiently convex R&D technology, we have shown that the counter-intuitive results are reversed. In the case of linear R&D technology, the socially optimal R&D policies and activities are indeterminate, but with convex R&D technology, optimal innovation and imitation subsidies would induce the market to generate socially 'balanced' innovative and imitative activities.  相似文献

Joint R&D projects have emerged as a significant model for the development of research and technological activities. Our study examines, through an exploratory analysis, the typology of joint R&D projects and the characteristics of R&D networks in which the projects are developed. In addition, the interrelation between the R&D projects in the context of European Technology Policy is analysed. Findings from survey data collected on joint R&D projects carried out in the context of European Framework Programmes indicate that three groups of R&D projects can be identified (invention, innovation and diffusion projects), and that each of these projects is managed inside the R&D network with a different degree of structuring and external opening. The analysis of interrelations between R&D projects also shows a low, non-linear and non-progressive interrelation. This conclusion is an important question to bear in mind in the design of scientific and technological policies.  相似文献

现阶段我国仍属于新兴市场经济国家,市场机制并不完善,中小企业的生存环境不容乐观.为提升中小企业市场竞争力,各级政府加大对其创新研发的资金和政策扶持力度对帮助其持续稳定发展有着十分重要的意义.本文从深市中小板上市企业中筛选出了471家企业在2014—2018年间的面板数据,利用回归模型进行实证检验,以探究政府资助政策对中小企业创新研发的影响.结果显示:政府的资助政策在整体上对科技研发投入产生了积极的作用,但对创新研发的产出没有直接影响;只有对科技研发人员进行投入才能给创新产出带来积极影响.因而,政府资助应该着重加强对科技人员的投入.  相似文献

This paper extends a two‐period overlapping generations model of endogenous growth where the interactions between public infrastructure and human capital with research and development (R&D) activities and growth are studied. The paper makes two important contributions. First, it accounts for the spillover effect of the stock of ideas on learning, which in turn promotes the production of innovative technologies. In doing so, it brings to the fore a two‐way interaction between human capital and innovation. The paper then applies various econometric methods which confirm the above theoretical thesis. Second, the solutions of the model emphasize the important role public spending on infrastructure, human capital and R&D can play in promoting economic growth. However, the findings also show that trade‐offs in the allocation of public spending may inevitably emerge. In particular, investment in public infrastructure at the expense of spending on R&D is less likely to succeed in promoting economic growth, whereas it may be more effective to foster growth through an offsetting cut in another productive component, namely, education. In light of these potential trade‐offs, governments in low‐income countries need to use their limited budgets as part of holistic measures in order to achieve efficient outcomes.  相似文献

This paper examines research and development (R&D) investment spillovers across different market structures. In particular, we extend the recent work in Matsumura et al. (2013) to incorporate R&D investment spillovers. When the market is a duopoly, noncooperative (cooperative) R&D investment is preferred for small (large) spillovers of less (more) than half. We show that as a market structure becomes more competitive, noncooperative R&D investment is more likely to be preferred. Moreover, noncooperative R&D is not always decreasing with the intensity of competition, even though it is ultimately zero with perfect competition. Our theoretical results fit well with existing empirical findings.  相似文献

Using French firm-level panel data, this study investigates R&D spillovers from inward foreign direct investment (FDI) with respect to both horizontal and vertical linkages (backward and forward). Using a Crepon, Duguet and Mairesse (CDM) model, we estimate an R&D-augmented Cobb–Douglas production function to assess the impact of R&D spillovers on firm performance. The results emphasize that international spillovers (from foreign affiliates to local firms) have a greater effect on firm performance than reverse spillovers (from local firms to foreign affiliates) and are more likely to be backward than forward. Moreover, the effect of backward spillovers depends on a firm’s absorptive capacity and is amplified in the case of outsourcing relationships.  相似文献
