Although a large amount of past research has studied the measurement of institutional research and development (R&D) efficiency, there has been limited dynamic empirical investigation of this topic. This study differs from previous studies in its consideration of R&D capital stock, which is defined as a carry-over activity between two consecutive periods. To further test high-tech institutes’ R&D performance in the pre-reform and post-reform periods, we evaluate a panel of 29 high-tech institutes of the Chinese Academy of Sciences (CAS) for 2011–2017 with a dynamic slacks-based measure. (a) The empirical value of the average overall efficiency is 0.5559, and the clustering analysis shows that institutes operating above the average overall efficiency level follow an increasing and then decreasing trend, while those operating below the average overall efficiency level follow a decreasing and then increasing trend. (b) The efficiency of low-performing institutes has increased from 0.2259 in the pre-reform period to 0.2727 in the post-reform period, which does not reflect the efficiency improvements of high-performing institutes. (c) High-tech institutes selected as pilot institutes have an average efficiency level of 0.6524, which is higher than that of non-pilot institutes (0.4765), indicating the benchmarking effect of pilots. (d) The types of pilot institutes can be ordered as follows: feature institutes > centres of excellence > innovative academies. (e) The total-factor input efficiency level has decreased in the post-reform period. Only the total-factor efficiency of high-quality papers has increased in the post-reform period (by 0.0094).  相似文献

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.  相似文献

We investigate the relation between abnormal research and development (R&D) investments change and expected stock returns. We provide evidence that firms that abnormally increase their R&D investments (RDI) earn higher returns in comparison to the market portfolio. Specifically, our findings document an economically significant annual positive abnormal RDI returns that ranges from 3.2% to 11.5%. These findings are robust to well-established risk factors in the literature and suggest that the abnormal increases in RDI impacts stock returns.  相似文献

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.  相似文献

本文利用要素市场扭曲指数及中国高技术产业1997~2009年省际面板数据,考察了要素市场扭曲对R&D投入的影响及区域差异。结果表明,要素市场扭曲对R&D资本投入和R&D人力投入有着不同的影响,抑制了R&D资本投入增长,促进了R&D人力投入;而且其对两者的影响都存在着显著的区域差异。在此基础上,运用门槛检验方法对这种区域差异的影响因素进行了探讨,研究发现,在区域经济发展水平、人力资本水平、财政收入、产权结构和对外开放程度等因素的不同门槛值区间,要素市场扭曲对高技术产业R&D投入的影响程度和方向都存在着明显的差异。  相似文献

We analyze how research and development (R&D) outsourcing influences product innovation. We propose a separation between learning from R&D outsourcing, whereby the firm improves its ability to innovate by using outsourced R&D directly in new products, from learning by R&D outsourcing, whereby the firm indirectly uses outsourced R&D by integrating it with internal R&D to create new products. Building on the knowledge-based view, we argue that learning from R&D outsourcing is likely to have an inverse U-shaped relationship with product innovation, because the initial benefits of using outsourced component R&D knowledge to innovate products is eventually outweighed by the hollowing out of the firm's ability to innovate. In contrast, we propose that learning by R&D outsourcing is likely to have a U-shaped relationship with product innovation, because the initial challenges of integrating internal and external R&D are eventually overcome, resulting in more innovations. Finally, we distinguish between domestic and foreign R&D outsourcing and propose a liability of foreignness in R&D outsourcing as it has a lower impact on new products than domestic R&D outsourcing. The empirical analysis shows that outsourced R&D has an inverted U-shaped relationship with the number of new products, while the interaction between outsourced R&D and internal R&D has a U-shaped relationship with the number of new products. It also shows that domestic outsourced R&D has a higher positive impact on the number of new products than foreign outsourced R&D.  相似文献

本文克服高技术产业研发过程非合意产出难以度量的问题,以未达标专利数量作为非合意产出,对各地区高技术产业的研发效率进行系统测度。研究发现:(1)随着创新要素的大量投入,中国高技术产业的总体研发效率水平却在逐年降低。造成这种现象的根本原因在于投入无效率与合意产出无效率,也即投入要素的大量增加并未有效推动创新产出的增加。(2)近年来中国东、中、西部地区高技术产业研发效率均呈现下降趋势,但东部地区技术落差比较高,其技术水平始终处于领先地位。(3)京津冀、长三角、珠三角等地区高技术产业研发效率呈现L型趋势。  相似文献

基于经济区域视角,本文运用中国创业板和中小板上市公司2011—2015年的面板数据,实证检验以研发相关的政府补贴和所得税优惠为主的财税政策对企业研发强度的作用效果,并验证区域创新能力对财税政策与研发强度关系的调节作用。研究发现:(1)相比东部地区,中西部地区的政府补贴对研发强度促进效果更加显著;相比长三角和珠三角地区,京津冀地区的政府补贴对研发强度促进效果更加显著。(2)相比中西部地区,东部地区的税收优惠对研发强度促进效果更加显著;相比京津冀和长三角地区,珠三角地区的税收优惠对研发强度促进效果更加显著。(3)区域创新能力对政府补贴与企业研发强度的关系有反向调节作用,而对税收优惠与企业研发强度的关系的调节作用不明显。与以往从宏观角度研究区域创新能力不同,本文从会计的视角研究了区域创新能力对财税政策与企业研发强度关系的影响,是一个有益的尝试。  相似文献

Process industries often have features that differ from other businesses, such as round‐the‐clock production and costly and specialized production processes—features that have not been dealt with in the project management literature. We highlight and identify the complexity of R&D projects in the Swedish process industry and its interrelated process development and product development activities based on results from interviews and a case study. The different competence areas in which a project manager must integrate and manage R&D projects is illustrated. We conclude that a project manager needs both production and product‐related competence, including customers' processes.  相似文献

We examine the theoretical implications of corporate income tax for a risky portfolio in a aggregate-endowment economy. In this model, corporate income tax affects the portfolio risk associated with the rebalancing motive during market clearance. An asset is defined as a portfolio of stocks and bonds whose portfolio weights are similar to financial leverage. Corporate tax can decrease after-tax consumption from dividends (increase leverage) and increase the tax shield that increases dividends (decrease leverage). Changes in dividends are responsible for the correlation between expected dividend growth and consumption growth and, thus, affect stock pricing and returns. Overall, the model is characterized by tax-induced portfolio risk associated with financial leverage.  相似文献

研发投资是企业的重大决策之一,董事会结构对研发决策过程和结果有重要影响。以2007—2019年A股上市公司为样本,采用研发支出粘性刻画研发持续性,从董事会断裂带这一结构特征探索影响企业研发持续性的组织因素。研究发现,董事会断裂带的存在降低了企业研发投入的持续性,即提高董事会团队的同质性有助于提升研发投入持续性。机制检验表明,董事会断裂带通过影响董事会的监督效能、目标决策导向与风险偏好三条路径影响研发持续性。异质性分析发现,董事会断裂带的深层特征会加剧其对研发持续性的抑制作用,而企业购买董事高管责任险能够缓解董事会断裂带对研发持续性的负向影响。区分研发支出变动类型后发现,董事会断裂带主要抑制“升多-降少”型研发支出粘性。研究结论为董事会结构的决策效应研究提供了新的证据,拓展了研发支出粘性影响因素的相关研究,也为我国企业加强董事会建设以提升研发连续性提供了理论指导与政策启示。  相似文献

本文研究五类代表性的投资组合模型:方差,绝对偏差,LPM模型,极大极小模型,以及最大绝对偏差模型,讨论不同的风险度量模型是否真的会造成资产配置的效果不同。区别于传统的从风险与收益的角度进行比较,我们研究5个风险模型得到的最优策略结构,通过权重和重叠的资产数目来探讨不同模型间的相似程度。我们的实证结果发现,不同的风险度量模型会对投资组合的构成造成非常显著的影响。这些结果对投资者或者基金经理进行投资实践具有非常重要的意义,因为传统的看法普遍认为模型的选择取决于投资者对风险的态度而不是从模型本身的理论或者实践价值来选择模型。  相似文献

ABSTRACT

This paper looks at the relation between the R&D knowledge base of city-agglomerations and knowledge sourcing in product innovative small and medium-sized enterprises (SMEs). The small open Belgian economy is used as a test case. The characteristics of the city-agglomeration’s R&D knowledge are posited to be instrumental for SMEs’ reliance on particular sources of information for innovation. The R&D knowledge base is studied as a multidimensional concept consisting of R&D capacity, R&D specialization and R&D diversification. A representative sample of product innovative SMEs drawn from two waves of the Community Innovation Survey between 2008 and 2012 reveals that a strong R&D capacity at city-agglomeration level favours private external information sources for innovation, but has no influence on the likelihood to rely on public sources for innovation. Accordance between specialization of the private R&D knowledge base and the SME’s activities positively influences the use of clients as information sources for innovation, whereas under these circumstances supplier responsiveness turns out to be less frequently solicited for. A more diversified private R&D environment reduces the reliance on universities and public research organizations as information sources for innovation. A public R&D knowledge base specialized in natural sciences or engineering favours information sources from universities.  相似文献

This research investigates the degree of emphasis placed by the Australian manufacturing industry on Research and Development (R&D) strategy as well as on other organisational strategies such as marketing, HRs (HR), technology, and operations at the functional level. The research extends further to investigate whether the emphasis on R&D strategy differs with contextual factors such as firm size, firm’s generic strategy, type of market, firm’s life cycle stage, etc. A mail survey was carried out to collect information from manufacturing firms across Australia. This was followed by an on-site interview of some of the senior managers of manufacturing firms from three Australian states: South Australia, Victoria and New South Wales.The study found that although the emphasis on R&D strategy has received a high priority in the past few years, it has not been as effective as the operations strategy and the technology strategy. The operations strategy has been accorded the highest importance in the past few years and this will continue in the future. The study also indicated that firms, which adopt a differentiation generic strategy, put more emphasis on R&D than the firms, which adopt cost leadership and focus generic strategies. The results did not indicate any evidence of a relationship between firm size and the R&D strategy although large firms are found to put more emphasis on operations and marketing strategies. Relatively higher emphasis was placed on the R&D strategy by businesses: at the growth stage; involved in the manufacture of consumer goods as opposed to industrial goods; involved in exports with a higher sales growth in export markets; and having a higher growth rate relative to their industry.  相似文献
