The Influence of Diversification and Market Structure on the R&D Intensity of Large Australian Firms
Mark Rogers 《The Australian economic review》2002,35(2):155-172
This article empirically investigates the determinants of R&D intensity for large Australian firms (1994–1997). The results indicate that more focused firms have higher R&D intensities and that lower levels of industry competition are associated with lower R&D intensities. 相似文献

This paper uses statistical data from the annual R&D survey of financial flows received or spent by the firm for R&D activities. To describe R&D networks, attention is focused on the construction of four synthetic proxies from empirical literature on social networks: variety of partners, intensity, regularity of links, and centrality in networks. On the bases of the two available innovation surveys, we explore, through a cross section study, the impact of these different variables on technological performance of firms. 相似文献

A significant relationship is found between the market value of the firm and its ‘intangible’ capital, proxied by past R&D expenditures and the number of patents, based on a time-series cross-section analysis of data for large U.S. firms. 相似文献

We construct an industry-equilibrium model in which it is costly for consumers who have previously purchased from one firm to switch to competitors. This gives firms a certain degree of market power over their established customers. The equilibria we identify under these conditions have the following properties: (1) there is a nontrivial size distribution of firms, although firms are intrinsically identical, (2) larger firms make higher profits, (3) larger firms spend more on R&D, (4) larger firms charge (on average) lower prices, and (5) profits are positively correlated over time. These properties match empirical regularities concerning the manufacturing and retail sectors in the U.S. economy. 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

R&D subsidies are a common tool of technology policy, but little is known about the effects they have on the behavior of firms. This paper presents evidence on the effects that R&D subsidies have on the R&D effort of recipients, and on the probability that a firm will participate in a program granting R&D subsidies. The empirical model consists of a system of equations: a participation equation; and an R&D effort equation. Endogeneity of public funding is controlled for. Estimates are obtained with a cross-section sample of Spanish firms. The main findings are that: 1) small firms are more likely to obtain a subsidy than large firms, probably reflecting one of the public agency's goals; 2) overall, public funding induces more private effort, but for some firms (30% of participants) full crowding out effects cannot be ruled out, and 3) firm size remains related to effort, whether or not a firm gets public funding. 相似文献

This paper uses data on patent-to-patent citations and patent-to-science-literature citations to study the spillover network of companies and research institutes around Philips Electronics. The theoretical section of the paper surveys the literature on innovation regimes and regional systems of innovation, and uses this to derive a number of testable hypotheses on the Philips network. The main findings of the paper are that the importance of local firms in the technology network around Philips is small, but the impact of local (semi-)public institutes is larger. Also, it is found that large firms generate a large part of the scientific literature that is referred to in Philips patents. 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

以2011—2016年中国沪深两市家族企业为样本,采用二手数据Tobit回归方法,研究了家族企业控制目标和盈利目标的实现与否对研发投入的影响。结果显示:供应商对家族企业的威胁越大,家族企业管理者为了实现控制目标越倾向于增加研发投入;家族企业管理者对盈利目标和控制目标的重视遵循注意力顺序理论,即当盈利目标未实现时,家族企业管理者更关注盈利状况,较少关注控制威胁,因此会减少研发投入;当盈利目标实现后,家族企业管理者才关注控制威胁、增加研发投入;家族企业的资源禀赋优势有助于控制目标的实现。 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

This paper studies vertical R&D spillovers between upstream and downstream firms. The model incorporates two vertically related industries, with horizontal spillovers within each industry and vertical spillovers between the two industries. Four types of R&D cooperation are studied: no cooperation, horizontal cooperation, vertical cooperation, and simultaneous horizontal and vertical cooperation. Vertical spillovers always increase R&D and welfare, while horizontal spillovers may increase or decrease them. The comparison of cooperative settings in terms of R&D shows that no setting uniformly dominates the others. Which type of cooperation yields more R&D depends on horizontal and vertical spillovers, and market structure. The ranking of cooperative structures hinges on the signs and magnitudes of three "competitive externalities" (vertical, horizontal, and diagonal) which capture the effect of the R&D of a firm on the profits of other firms. One of the basic results of the strategic investment literature is that cooperation between competitors decreases R&D when horizontal spillovers are low; the model shows that this result does not necessarily hold when vertical spillovers are sufficiently high, and/or when horizontal cooperation is combined with vertical cooperation. 相似文献

Following the recent literature on institutions and economic growth, we examine the effects of property rights protection on corporate R&D. Using a unique 2003 World Bank survey of over 2400 firms in 18 Chinese cities, we obtain the following findings: (1) property rights protection is positively and significantly related to corporate R&D activity (for both process and product R&D); (2) government services and helping hand are conducive to corporate R&D, while informal payments to government officials are not; and (3) government ownership of firms and direct appointment of CEOs are negatively associated with corporate R&D activities. We also find that corporate R&D is positively related to firm size, and access to finance, but negatively related to product market competition and firm age. 相似文献

This study presents a model capturing sources of Australian aggregate labour productivity using annual time series data from 1970 to 2001. Labour productivity, or real output per hour worked, in this model is determined by real net capital stock in information technology and telecommunications (ITT), real net capital stock in the non-ITT sector, trade openness, human capital, the wage rate, international competitiveness, and the union membership rate. Given the lack of long and consistent time series data, multivariate cointegration techniques are inappropriate as the cointegration results will be sensitive to the lag length, the inclusion or exclusion of the intercept term or a trend in the cointegration equation and/or the vector autoregression (VAR) specification. Therefore, the Engle-Granger representation theorem and the Hausman weak exogeneity test have been employed to determine the short and long-term drivers of Australian productivity. Empirical estimates indicate that, in the long-term, policies aimed at promoting various types of investment, trade openness, international competitiveness, and the use of wage as a stimulant in a decentralised wage negotiation system, will improve labour productivity. In the short term, all the above variables except for human capital and labour reforms, which both need more time to evolve, determine productivity performance. 相似文献
