We investigate financing constraints for R&D in China. We find that Chinese private firms are financially constrained for R&D, while state-owned enterprises are not. Mature private firms encounter more severe financing constraints for R&D than young private firms. Moreover, the expansion of external financing supply does not relax the financing constraints for R&D faced by private firms.  相似文献

This papcr uses a new firm panel data set to explore the relationship between R&D and productivity in German manufacturing firms for the period from 1979 to 1989. The results confirm the view that K&D is an important determinant of productivity growth. In the cross-section, the elasticity of sales with respect to R&D capital is on the order of 14 per cent. Using fixed-effects estimators yields R&D elasticities of about 8 per cent. Assuming different depreciation rates for R&D capital has virtually no effect on these results. Differencing estimates improve considerably when growth rates are computed over longer time periods, suggesting that the divergence between time-series and cross-sectional estimates is driven by random measurement errors. The paper also considers differences between high technology and other firms. Cross-section and panel elasticity estimates of the R&D effect diverge considerably for the two groups, while the corresponding rate of return estimators display far less variation. There is some evidence that the R&D elasticity increased during the early 1980s, and that it fell sharply back to its 1979 value during the period from 1985 to 1989.  相似文献

We decompose the recent patent increase into components representing (1) an increase in resources made available to research and development, (2) an across-the-board rise in the patent yield of an R&D dollar, and (3) changes in the patent yield in individual industries. Two high tech fields, computer hardware and pharmaceuticals, account for 22 percent of the patent increase. While these two industries had the fastest R&D growth among the industries we study, the pharmaceutical industry experienced a decline in its patent yield, limiting its patent growth. We show that increased R&D spending accounts for 70 percent of the patent increase. We discuss our results in the context of alternative hypotheses of the patent surge. We also compare our results to the anecdotal evidence of firm R&D performance at the industry level.  相似文献

Shareholding structure, depoliticization and firm performance   总被引:2,自引:0,他引:2  
In this study we use a dataset that provides information on Chinese Communist Party grassroots organizations’ political control over decision‐making in China's listed firms. Specifically, we examine how different types of shareholders affect (1) the party's level of decision‐making power and (2) the implications of party control for firm performance. We obtain two major results. First, we find that the proportion of shares held by domestic individual shareholders is negatively related to the party's level of decision‐making power. Second, we find that the existence of large institutional investors is associated with a reduced negative performance effect of party control. Our results suggest that both the exit and the voice channels may offer mechanisms for depoliticizing China's listed firms and improving their performance. This study both addresses an important corporate governance issue relevant to China's listed firms and offers interesting information in terms of comparative studies of corporate governance and reform strategies in transitional economies.  相似文献

Although the econometric evaluation of R&D has attracted wide interest in many countries, it has not attracted much in the UK. The main objective of this paper is to fill this void, i.e., to estimate the impact of R&D on productivity growth of the UK manufacturing sector. However, there are some additional objectives. Firstly, we estimate the impact of R&D on productivity growth of large and small firms and we discuss a number of theoretical arguments regarding the role of firm size. Secondly, given that the technological infrastructure influences the innovative capacity of a firm, we compare the impact of R&D on productivity growth of high-tech firms with the corresponding impact on productivity growth of low-tech firms. Thirdly, we investigate whether the contribution of R&D to productivity growth has changed over time.

Based on firm-level data (78 firms, 1989–2002), we find that the contribution of R&D is approximately 0.04. Although the R&D-elasticity of large firms (0.044) is higher than the corresponding elasticity of small firms (0.035), the difference is small. In contrast, the R&D-elasticity is considerably high for high-tech sectors (0.11), but statistically insignificant for low-tech sectors. Finally, the investigation of the elasticity of R&D over time revealed an interesting discontinuity showing that although until 1995 the R&D-elasticity was approximately zero, after 1995 it increased dramatically to 0.09. We investigate the potential causes of such non-linearity and we suggest a number of possible explanations.  相似文献

R&;D: A Small Contribution to Productivity Growth   总被引:3,自引:1,他引:3  
In this article I evaluate the contribution of R&D investments to productivity growth. The basis for the analysis are the free entry condition and the fact that most R&D innovations are embodied. Free entry yields a relationship between the resources devoted to R&D and the growth rate of technology. Since innovators are small, this relationship is not directly affected by the size of R&D externalities, or the presence of aggregate diminishing returns in R&D after controlling for the growth rate of output and the interest rate. The embodiment of R&D-driven innovations bounds the size of the production externalities. The resulting contribution of R&D to productivity growth in the US is smaller than 3–5 tenths of 1% point. This constitutes an upper bound for the case where innovators internalize the consequences of their R&D investments on the cost of conducting future innovations. From a normative perspective, this analysis implies that, if the innovation technology takes the form assumed in the literature, the actual US R&D intensity may be the socially optimal.  相似文献

Business cycles might affect firms'?ability and incentive to perform R&;D. Firms finance most R&;D activities out of cash flow so when cash flow decreases the funds available for R&;D also decreases. This limits the ability of firms to perform R&;D, potentially leading to reduced R&;D expenditures during recessions. However, business cycles also influence the incentive to perform R&;D. The opportunity cost of funds devoted to R&;D falls during recessions since the return on production will likely be lower than during an expansion. During recessions, this provides firms with an incentive to redistribute an existing pool of funds away from production and towards R&;D projects. This paper tests whether the business cycle influences the incentive and ability of firms to engage in R&;D activities, in particular examining whether the response is symmetric across the business cycle.  相似文献

This paper uses a comprehensive firm level data set for the manufacturing sector in Italy to investigate the effect of government support on privately financed R&D expenditure. Estimates from a non‐parametric matching procedure suggest that public assistance has a positive effect on private R&D investment in the sense that the recipient firms achieve more private R&D than they would have without public support. This indicates that the possibility of perfect crowding out between private and public funds can be rejected. Furthermore, in this sample of Italian firms, tax incentives appear to be more effective than direct grants. The paper also examines whether public funding affects the financial sources available for R&D and finds that grants encourage the use of internal sources. The results also show some evidence of positive effects on credit financing for R&D.  相似文献

A considerable share of R&D investment is due to multinational firms that simultaneously operate R&D bases at home and abroad. We develop a simple model of foreign and domestic R&D investment and test the model's predictions on a sample of 146 Japanese multinational firms’ R&D investments in Japan and the United States in 1996. The empirical results confirm that the foreign to domestic R&D ratio depends on relative technological opportunities and relative demand conditions, with foreign research expenditures responding to technological opportunity and foreign development expenditures responding to demand.  相似文献

ABSTRACT

We use Office for National Statistics' micro data for large UK establishments in the production industries in the period 1997–2008 to study the relationship between their productivity and the presence of substantial R&D activities, either at the production unit itself, or at other UK reporting units owned by the same enterprise group. We estimate that total factor (revenue) productivity is on average about 14% higher at the establishments which have substantial R&D themselves, compared to those with no R&D. Among the establishments with no R&D themselves, we estimate that productivity is on average about 9% higher at those which belong to enterprise groups which do have substantial R&D elsewhere in the UK in the same sub-sector. For the establishments with substantial R&D themselves, we also estimate a significant positive relationship between current productivity and past R&D expenditure using dynamic specifications which allow for both establishment-specific ‘fixed effects’ and a serially correlated error component.  相似文献

ABSTRACT

This study aims to investigate dynamic relationships between research and development (R&D) expenditure, climate change (measured by annual rainfall and temperature variations), human capital (proxied by literacy) and total factor productivity (TFP) growth in Bangladesh agriculture. Pesaran’s Pooled Mean Group (PMG) estimator is used to a unique panel data of 17 regions of Bangladesh covering a 61-year period (1948–2008). In addition, the panel vector autoregression (PVAR) model is also applied to trace the responsiveness of TFP from a shock to R&D, extension services, and literacy rate. Results reveal that R&D has an insignificant impact on TFP in the short-run, while it has a significant positive impact in the long-run. The contributions of climate variables (i.e., rainfall and temperature variations) are highly significant and negative in the long run. The literacy rate is found to have a significant positive impact on TFP as expected. These results suggest that agricultural R&D investment and human capital could play an important role to ameliorate the adverse effects of climate change in the agricultural sector of Bangladesh.  相似文献

Europe's innovation gap relative to the USA is often attributed to its industrial structure in which new firms do not play a significant role, especially in high-tech sectors. This view of a structural European Union (EU) innovation deficit is popular in European innovation policy discussions, but has received little or no thorough empirical investigation. This article aims to address this ‘evidence gap’. Using industrial R&D Scoreboard data from leading world innovators, we find that compared to the USA, the EU has fewer young firms among its leading innovators. Using a decomposition analysis, we show that having fewer young firms accounts for about one-third of the EU–US differential in R&D intensity, while 55% of the differential is due to the fact that young leading innovators in the EU are less R&D intensive than their US counterparts. Further analysis shows that this is almost entirely due to a different sectoral composition. We thus confirm that the EU–US private R&D gap is indeed mostly a structural issue.  相似文献

We analyze the influence of endogenous productivity asymmetries between firms, in terms of competitiveness and size, on multinational activity. In the model, productivity depends on cost-reducing R&D (research and development). We show that when firms differ on commitment power in R&D, the R&D leader, independently of being a multinational or a domestic firm, tends to invest more in R&D than the R&D follower. Because of these productivity advantages, the R&D leader can more easily become multinational. Therefore, in addition to the proximity-concentration trade-off, we identify another FDI (foreign direct investment) determinant: technological competition.  相似文献

This paper analyses strategic R&D policy in a third-country trade model where multiproduct firms with different production technologies compete in a vertically differentiated market. I show that the optimal R&D policies for both countries are subsidies when the product market is under price competition.  相似文献

This article proposes a generalized productivity decomposition approach to evaluate the contribution of firm innovation to aggregate productivity growth (APG) of China’s manufacturing industry. Results indicate that APG is mainly driven by firm-level productivity improvements, while across-firm resource misallocations lead to sizable productivity losses. The weak contribution of firm innovation to APG is found to be mainly caused by resource misallocations within innovating firms. The results suggest that firm innovation has not yet taken a dominant driving force for APG.  相似文献

Research and Development (R&D) service firms make significant contributions to innovation in other businesses. The extant literature considers these firms a homogenous sub-group of Knowledge Intensive Business Service firms (KIBS). The objective of this study is to investigate how R&D service firms innovate and the variety of innovation practices within these firms. Employing data from semi-structured interviews with senior managers from 32 UK-based R&D service firms, we suggest that there are two different modes of innovation: in the first mode, R&D service firms innovate similarly to KIBS whose innovation is ad-hoc in nature and driven by customers’ requests; another group of R&D service firms innovate like New Technology-based Firms (NTBFs) relying more on structured in-house R&D activities.  相似文献

This paper analyzes how firms’ R&D investment decisions are affected by asymmetries in knowledge transmission, considering different sources of asymmetry such as unequal know-how management capabilities and spillovers localization within an international oligopoly. We show that a better ability to manage knowledge flows incentivizes the firm to invest more in R&D. By introducing geographically bounded spillovers, we also find that one-way foreign direct investment (FDI) stimulates the multinational enterprise to raise its own R&D and that an FDI equilibrium is more likely to occur. Finally, spillovers localization leading to two-way FDI is welfare improving when compared with non-localized spillovers.  相似文献

This paper studies the firm’s decisions on in-house R&D and its procurement from outside through commissioned R&D, joint R&D, and technology acquisitions (i.e., licensing-in). Using the data about 14,000 manufacturing firms in Japan, we estimate a modified double-hurdle model in which the first hurdle determines whether the firm should perform any R&D at all and the second hurdle determines whether (and how much) it should perform each mode of procured R&D. The results generally support the two major theories—the transaction cost theory and the capability theory. The estimated positive effects of firm size, in-house R&D intensity, diversification, and vertical integration support the hypothesis that capability is needed for procured R&D, while the estimated positive effect of the index of appropriability by patents supports the hypothesis that this appropriability reduces transaction costs. In addition, we found that information flow from scientific sources and that from transaction-based sources affect the three modes of procured R&D differently.  相似文献

This article proposes a theoretical knowledge-driven horizontal research and development (R&D) endogenous-growth model to explain, for 10 innovative countries, the co-movement of the respective R&D intensity, economic growth and firm-size growth, by exploring short-medium-run and long-run growth effects. Bearing in mind some recent literature, we improve the R&D technology, by considering that R&D is more labour intensive through time as complexity increases, that the diffusion of designs is affected by coordination, organizational and transportation costs, and that a potential entrant will come up with the right idea is reduced because of the presence of a larger number of entrants. We show that when the economy is not initially in a steady state, it can take a saddle path towards the unique and locally saddle-path stable interior steady state. Both transitional-dynamics and steady-state behaviours of our theoretical model are then consistent with, respectively, the time-series and the cross-sectional evidence.  相似文献

This study examined the moderating effects of two kinds of internal R&D (parent R&D and subsidiary R&D) on the relationship between local R&D outsourcing and subsidiary productivity as internal R&D challenges the collaborative relationships in the local environment. Due to the specific feature of a subsidiary mandate, we further investigate whether two distinct kinds of internal R&D have different moderating effects between exploitation-oriented subsidiaries and exploration-oriented subsidiaries, based on a sample of longitudinal data set of 263 Taiwan-based manufacturing subsidiaries over the period 2006–2009. The empirical results show that for exploitation-oriented subsidiaries parent R&D plays a significant and negative moderating role on the impact of local R&D outsourcing based on local collaboration, while a positive moderating role is observed with parent R&D and subsidiary R&D for exploration-oriented subsidiaries.  相似文献
