基于状态空间模型的政产学研资协同创新四螺旋影响因素实证研究 总被引:1,自引:0,他引:1
在三螺旋理论框架下,搭建政府、产业、大学、研究机构和资本部门四螺旋模型,运用文献归纳法选取多元主体协同创新6类影响因素,以主体间协同程度测度结果为因变量基础,利用状态空间模型动态分析这些因素影响方向、大小和趋势。实证结果表明,中国经济因素表现为促进作用持续提升;中国技术市场规模和创新产业规模表现为先抑制后促进,且促进作用不断提升;中国产品市场需求和创新投入表现为抑制作用持续提升;中国创新产出在时间上表现为促进作用先提升后下降并最终稳定的状态。最后,提出不同政策建议,以促进中国政产学研资协同创新体系后续发展。 相似文献

This study has two related goals – one very specific and one more general. The specific goal is to constructively engage with Lodhia (2017) on the issue of whether and to what extent ‘qualitative cousins’ are well served by Faff's (2015) original pitching research (PR) template. Using this ‘cousins’ focus as a primer, the more general goal is to update the agenda created by Faff (2015) and in so doing, explore the ‘extended family’ of PR work/resources now available. 相似文献

We study the characteristics of all published papers in the top three finance journals (JF, JFE and RFS), and how these paper characteristics affect the number of citations in Google Scholar and the Web of Science database. First, we find the characteristics in the universalist perspective remain constant while the characteristics in the constructivist and presentation perspectives increase over time. Second, some characteristics are significantly different between the high-impact and the low-impact papers. Third, paper quality, research method, journal placement and paper age are the most important drivers. Last, different drivers play different roles in different journals. 相似文献

Denigration of academic experts and expertise, amid a resurgence of political populism, poses a challenge to the legitimacy of academic research. Addressing this challenge requires us to continually demonstrate the importance of basing policy interventions on reliable evidence, rather than unevidenced assertions that gain traction through communication echo chambers. However, unconscious confirmation biases in collection and analysis of evidence can impair the reliability of our research insights. A key source of such confirmation biases are unchallenged ideologies and other taken-for-granted assumptions underlying any research (sub)field. This essay argues that informal and formal peer review processes at many stages of research need to highlight and challenge both conscious selectivity bias and unconscious confirmation bias. However, they are unlikely to do so where researchers only take on board feedback from peers in the same (sub)field who share ideological commitments and taken-for-granted assumptions. In such circumstances, self-referential peer review echo chambers can develop that entrench rather than challenge weaknesses in a research (sub)field. This can be a major risk to the effectiveness and reputation of any academic research (sub)field; a risk we need to confront. 相似文献

Innovation clusters combining public and private effort to develop breakthrough technologies promise greater technological advances to slow down climate change. We use a multi-country model with an emission trading system to examine whether and how international climate policy can incentivize countries to create such innovation clusters. We find that a minimal carbon price is needed to attract applied research firms, but countries may nevertheless fail to invest in complementary research infrastructure. We construct a mechanism that leads to innovation clusters when emissions targets are set before uncertainty surrounding technological developments is resolved. It is a combination of low permit endowments for the country with the lowest costs to build the needed infrastructure, compensation for this country by profits from permit trade, and maximal possible permit endowments for the remaining countries. We outline how the EU-ETS can be further refined according to this mechanism. 相似文献

数字经济是新时代引领中国经济高质量发展的关键抓手。然而现阶段数字经济普惠性发展尚未实现,掣肘着其对国内全要素生产率的提升力度。文章在理论分析的基础上,基于熵权TOPSIS法测算了2012-2018年中国数字经济发展水平指数,探讨了中国数字经济对全要素生产率的影响机理。研究发现:数字经济的发展显著提升了中国全要素生产率水平,但区域层面上,东部地区的数字经济发展明显领先于中西部地区,引领着中国全要素生产率快速增长。从全要素生产率的分解指标来看,数字经济推动了技术效率提升,但现阶段国内关键核心技术环节薄弱以及数字产业化带来的人才和资金的虹吸效应导致数字经济对技术进步产生了阻碍作用。此外,当前数字经济对不同产业的渗透度存在明显的不均衡性,筑高了创新资源的流动壁垒,影响产业间协调创新及合理化布局,进而抑制了对全要素生产率的提升力度。进一步的机制检验表明在创新环境的支持下,人才集聚及金融规模强化了数字经济对全要素生产率的提升力度。 相似文献

In this paper, we focus on the question to what extent machine learning (ML) tools can be used to support systematic literature reviews. We apply a ML approach for topic detection to analyze emerging topics in the literature—our context is accounting and finance research in the Asia–Pacific region. To evaluate the robustness of the approach, we compare findings from the automated ML approach with the results from a manual analysis of the literature. The automated approach uses a keyword algorithm detection mechanism whereby the manual analysis uses common techniques for qualitative data analysis, that is, triangulation between researchers (expert judgement). From our paper, we conclude that both methods have strengths and weaknesses. The automated analysis works well for large corpora of text and provides a very standardized and non-biased way of analyzing the literature. However, the human researcher is potentially better equipped to evaluate current issues and future trends in the literature. Overall, the best results might be achieved when a variety of tools are used together. 相似文献

The aim of this paper is to investigate the impact of internal and external research collaborations on the scientific performance of academic institutions. The data are derived from the international SCOPUS database. We consider both quantity (the number of publications) and quality indicators (the field-weighted citation impact and the share of publications in the 10% most-cited articles) to evaluate universities' performance in some European countries (Germany, France, Italy, the UK and Russia). To this end, we develop a non-overlapping generations model to evidence the theoretical idea of research externalities between academic institutions. Moreover, we implement an empirical model to determine the extent to which the impact of internal and external collaborations on universities' performance is sensitive to the geographical dimension of the data. 相似文献
