This paper presents microeconometric evidence on financing constraints for research and development activities in German small‐ and medium‐sized firms (SME). Special attention is paid to the role of public research and development (R&D) subsidies. For this purpose SMEs in West and East Germany are compared because these regions are very different in their supply of public R&D funding. The empirical evidence suggests that West German SMEs are financially constrained in their R&D activities by both internal and external resources. In East Germany, firms are not sensitive to external constraints, possibly due to high public R&D subsidies. The results show that R&D in East Germany is to a large extent driven by public subsidies and that the usual financial market mechanisms are dysfunctional with respect to R&D in this region.  相似文献

ABSTRACT

This paper integrates innovation input and output effects of R&D subsidies into a modified Crépon–Duguet–Mairesse (CDM) model. Our results largely confirm insights of the input additionality literature, i.e. public subsidies complement private R&D investment. In addition, results point to positive output effects of both purely privately funded and subsidy-induced R&D. Furthermore, we do not find evidence of a premium or discount of subsidy-induced R&D in terms of its marginal contribution on new product sales when compared to purely privately financed R&D.  相似文献

This article analyses the effects of public R&D subsidies on R&D input and output of German firms. We distinguish between the direct impact of subsidies on R&D investment and the indirect effect on innovation output measured by patent applications. We disentangle the productivity of purely privately financed R&D and additional R&D investment induced by the public incentive scheme. For this, a treatment-effect analysis is conducted in a first step. The results are implemented into the estimation of a patent production function in a second step. It turns out that both purely privately financed R&D and publicly induced R&D show a positive effect on patent outcome.  相似文献

ABSTRACT

The objective of this paper is to analyse the impact of public funds for innovation on firm’s capabilities, innovative dynamics and economic performance. A large stream of literature about the evaluation of public funds is focused on testing the existence of additionality effects on investments and results. This paper aims to provide evidence about other dimensions of the firm that public policy can alter, with focus on the time window between the treatment and the impact, and the role of the Matthew effect (recurrence) in this process. The empirical exercise is based on a dynamic panel data made of 1465 firms (3337 observations) that applied to the Argentinean Technological Fund (FONTAR), which is the main public fund for innovation in Argentina, between 2007 and 2016. Results show short-term effects of accessing to FONTAR on firms’ capabilities, medium-term effects on innovation efforts and long-term effects on productivity. Even though the effect on productivity is larger among recurrent firms, the differences among recurrent and non-recurrent firms are not conclusive in case of capabilities and innovation efforts. All in all, this research provides evidence about the ‘when’ of public policy and the need to look beyond input additionality effects when analysing its impact.  相似文献

We analyse the impact of public subsidies on private sector research and development (R&D) activity for a sample of East German firms. Using propensity score matching, our empirical results indicate that subsidized firms indeed show a higher level of R&D intensity (R&D expenditures relative to total turnover) and a higher probability for patent application compared with non‐subsidized firms. We find that, on average, the R&D intensity increases from 1.5% to 3.9%. The probability of patent application rises from 20% to 40%. These results closely match earlier empirical findings for East Germany. Given the fact that the East German innovation system is particularly driven by small‐ and medium‐sized enterprises (SMEs), we draw special attention to the effectiveness of R&D subsidies for this latter subgroup. Here, no specific empirical evidence is available so far. Our findings indicate that policy effectiveness also holds for private R&D activity of SMEs, with the highest increase in terms of R&D intensity being estimated for microbusinesses with up to ten employees.  相似文献

Generating the greatest benefit from public research programmes is a major aim for industry managers and policy administrators alike. However, how to measure whether benefit has occurred createsf a considerable dilemma for managers and policy-makers. One approach centres upon the concept of ‘additionality’ or ‘what difference the policy has made’. Traditional ‘input additionality’ measures of subsequent research and development activity, for example, neither incorporate all impacts nor give adequate signals about adequate signals about aspects of ‘output additionality’, such as the impact on increased competitiveness at the level of the firm, or national competitiveness, the ultimate goal for the majority of research policies. An intermediate form of impact, ‘behavioural additionality’, centred upon changes in a firm's subsequent managerial behaviour, is considered to provide an alternative, yet compelling perspective on the impact of public support on the conduct of research. This study outlines empirical eveidence found for the various forms of additionality in a New Zealand collaborative research programme. It discusses how managers and policy administrators can exploit the occrrence of behavioural additionality to maximize the impact of a research policy, on the basis that modified behaviour is likely to strengthen a policy' latent abilityto influence the creation of output additionality. In such circumstances, the study suggests that managers and policy-makers should be identifying those interventions that lead to sustained improvements in mangerial practice, and in competitiveness, and should be managing their diffusion within firms and throughout industries.  相似文献

Whereas the provision of R&D subsidies has been central to public policy for many years, governments have recently become increasingly involved in stimulating cooperation for innovation and R&D. In many countries, financial support for technology intermediaries has become one of the key measures of indirect public support. However, little research has assessed the impact of indirect policy measures. In this paper, we shed light on the conditions under which technology intermediaries contribute to knowledge and networking outcomes generated by the firms that call upon them. We hereby focus on firm network and competence additionality as measures for cognitive capacity additionality and study the impact of technology intermediaries on firms. In doing so, we distinguish between R&D and R&D related activity technology intermediaries engage in. The results indicate that absorptive capacity of the technology intermediary does not affect cognitive capacity additionality generated by firms in R&D activities, while the results for R&D related activities are mixed and depending on the type of cognitive capacity additionality studied. The absorptive capacity of firms does not directly affect cognitive capacity additionality, but the results of mediation analysis show that firms with higher levels of absorptive capacity use the services of the technology intermediary more intensively, and subsequently generate higher levels of cognitive capacity additionality.  相似文献

This paper is one of the first attempts in the literature to evaluate the effectiveness of R&D policies in Europe during the great crisis of the late 2000s. Using homogenous firm-level data for the largest EU Member States over the period 2007–2009, we test whether manufacturing firms receiving public subsidies spent more on R&D. The analysis is performed using both non-parametric techniques and parametric estimation methods accounting for the possible endogenous selectivity of R&D subsidies. The hypothesis of full crowding-out is rejected in all countries under exam as firms did not replace their own resources with public grants. However, these firms did not allocate additional funds to research and hence, differently from earlier works, we do not find evidence for additionality effects of R&D subsidies. Our estimates indicate that, albeit not expansive, public subsidies to R&D thwarted the reduction of firm R&D efforts in the aftermath of economic crisis.  相似文献

文章以中国上市公司微观数据为样本,运用能克服样本自选择性的计量方法估计R&D税收激励的专利效应,并以知识生产函数分析其作用机制.结果表明,与没有获得R&D税收激励的厂商相比,获得R&D税收激励的厂商并不具有更高的专利产出.从作用机制上看,尽管R&D税收激励产生了显著的额外研发支出效应,但该效应并未直接增加企业的专利产出,中国的R&D税收激励面临类似"欧洲悖论"的困境.仅在知识产权保护的调节下,R&D税收激励引致的额外研发支出能间接增加专利产出,知识产权保护缓解了R&D税收激励政策失灵的风险.前述结论通过了稳健性检验.未来,为改善我国R&D税收激励的创新效应,走出"欧洲悖论"困境,需要优化R&D税收激励政策设计和强化知识产权保护的激励功效.  相似文献

选取2011—2017年中国新能源行业122家上市公司面板数据,建立面板向量自回归模型(PVAR),通过研究政府环境研发补贴、企业研发投入和环境绩效之间的动态交互关系,考察政府补贴对企业创新的激励效应以及补贴的配置合理性问题。结果表明:一方面,环境研发补贴对企业研发投入和环境绩效均存在滞后1~4年的影响。政府补贴促进企业研发投入,非国企比国企显著;政府补贴对环境绩效的影响在不同产权性质企业中存在较大差异,补贴显著抑制了国企环境绩效,但有效促进了非国企环境绩效。另一方面,企业研发投入与环境绩效对于后续政府补贴投入分别具有滞后1~4年和1~2年的正向反馈作用。针对国企,政府补贴决策是结果导向的,即更关注其环境绩效;对于非国企,政府补贴决策偏好过程导向,即更多地考察企业对研发活动的投入情况。研究结论可为完善中国新能源企业环境补贴政策,提高新能源企业环境研发水平和环境绩效提供参考。  相似文献
