AbstractConcepts like regional innovation systems, innovative milieu and learning regions emphasise the positive contribution of intra-regional cooperation to firms’ innovation performance. This claim is, however, primarily backed by qualitative evidence, as few studies test this issue with quantitative approaches. Using data on co-application and co-invention of patents for 270 German labour market regions, this study shows that cooperation intensity and regions’ innovation efficiency are empirically associated in a negative way. This particularly concerns missing or very extensive inter-regional cooperation. In contrast, medium intensities of regional cooperation have rather positive effects. 相似文献

基于中国1985—2009年的时间序列数据,将能源作为一种生产要素引入D-S形式的总量生产函数,利用扩展了的内生增长模型,实证检验不同专利活动对能源及劳动产出弹性的影响差异。结果发现专利活动特别是发明专利对劳动力的产出弹性发挥了明显的促进作用,专利活动对我国能源产出弹性的整体贡献较小,专利活动对能源产出弹性的影响主要体现在实用新型专利上,发明专利和外观设计专利对能源产出弹性的提升没有发挥显著促进作用。 相似文献

区域经济的发展离不开创新,离不开研究与开发活动(R&D),研究区域R&D活动的投入与产出关系,对探明区域经济的发展动力,提升区域创新能力有重要的理论和现实意义。利用计量经济学模型,以河北省R&D活动的投入与专利产出的关系为研究对象,以河北省R&D资源投入、工程师和科学家数量为投入指标,以专利为产出指标,对区域R&D资源与专利产出的关系进行定量研究,发现河北省的R&D投入产出弹性较高,专利对科研资金的产出弹性为0.43,专利对科学家和工程师的产出弹性为1.46,高于同期的全国平均水平,最后结合实际进行了原因和对策分析。 相似文献

Using Chinese data, this paper reveals that climate disaster events have a positive impact on the granting of green invention patents. The occurrence of climate disasters leads the patent-granting officials to overestimate the likelihood of disaster recurrence, strengthens their perception of environmental protection as urgent, and consequently increases the number of patents that they grant. Salience bias, the tendency to overestimate probabilities due to the occurrence of salient events, is widely studied in psychology and behavioral finance. This paper extends this research by examining the influence of salience bias on people's behavior in processing green invention patents, with a specific focus on climate disaster events in Beijing, the headquarters of China's patent examination authority. In addition to the overall positive impact on granted patent numbers, the paper finds that (i) the influence of salience bias is temporary, with a more pronounced effect on energy-saving patents than on other categories of patents, and (ii) the primary effect is on green invention patents filed by firms in Beijing, with the effect of salience bias rapidly diminishing as the distance of the application city from Beijing increases. 相似文献

Patent applications by male New Zealand inventors sharply increased in the early 1880s after initial official fees were reduced, and the requirement to advertise applications in newspapers abolished. Increasingly, however, applications lapsed, while applications by unskilled workers remained low. Non-fee costs were crucially important, with the 1870 reduction in fees failing to increase patenting, as hoped, because the doubling of mandatory advertising costs negated the fees reduction. Patenting by overseas inventors was less affected by fees, and steadily grew. Only one application was by an indigenous Māori person, while even in 1899 women made just 2.5% of applications. 相似文献
