是否获得溢出效应是评价东道国引进外资实绩、调整东道国外资政策的重要依据.利用1991-2002年的省际资料,本文测度了外商直接投资对我国科技创新的外溢效应,分析了影响外溢效应的主要因素.研究发现,通过提高国内科技资本投入的产出效率,外资对我国的科技进步产生了积极的促进作用.从总体上来看,随着时间的推移,外资对我国科技创新的边际溢出效应不断提高.但外溢效应存在着地区差异,这主要源于各地区在宏观和微观吸收环境上的差异. 相似文献

基于“技术锁定”和转型升级的考虑,本文首先探讨了全球价值链下逆向技术外溢的微观机理和实际效果,并运用1985-2010年间相关数据测算我国OFDI渠道吸收的主要国家研发资本存量,采用国际R&D外溢回归方法实证分析了OFDI逆向技术外溢对我国技术进步的影响.结论显示:逆向技术外溢正效应凸显,但其作用远小于国内研发资本的积极作用:流向发达国家的投资产生的逆向技术外溢强于发展中国家的投瓷回报. 相似文献

三重知识溢出与新兴经济体创新升级 《科学学研究》2021,39(6):1130-1143
综合考究本土外资知识溢出、逆向知识溢出和本土内资知识溢出对新兴经济体的系统性影响,有助于深度认识知识溢出体系在国内创新升级中所扮演角色,发现创新拐点。文中通过构建理论模型论证了三重知识溢出的整体关联性,并在异质性样本条件下实证了该整体与我国创新升级之间的内在关联。结果显示：整体视角下,三重知识溢出对国内创新升级的总效应、直接效应和间接效应均表现为正向促进作用;分视角下,源于一带一路沿线国家的外资知识溢出和本土内资知识溢出组合在总效应方面正向促进国内创新升级,但本土外资知识溢出的直接效应以及逆向知识溢出发挥的间接效应与国内创新升级表现为负相关;来自非沿线国家的三重知识溢出总效应对国内创新升级同样表现出正向促进作用,但逆向知识溢出的直接效应表现为抑制作用;此外,所有样本检验结果均表明知识溢出方和知识接收方之间技术差距有益于促进国内创新升级,但双方的人力资本差距与国内创新升级负相关。 相似文献

知识溢出是企业集群发展、提高创新能力、获得持续竞争优势的驱动因素之一,但其过程仍是一个"黑箱"。应用系统动力学模型分析在高技术产业集群内组织间的知识溢出过程中,知识的难度系数、自然溢出度、接收者的创新能力、溢出者和接收者的初始知识势差对组织知识存量和组织间知识势差的影响,得到的结论是,知识的难度系数、知识势差一定程度上阻碍知识溢出,而自然溢出度和接收者的原始创新能力则加速知识溢出。 相似文献

The scope of this paper is to report new empirical evidence on the determinants of R&D co-operation. Indeed, the literature on the capabilities of firms emphasises the role of knowledge in the performance and evolution of firms who use knowledge developed in others to build their own knowledge capital. R&D co-operation between firms is one of the many strategies by which this knowledge may be transmitted. Several theoretical models have stressed that R&D co-operation is more likely when the level of spillovers is high. While this supposition is used in many theoretical models, it has rarely been tested before. Our results do not lend strong support to this intuition. Indeed, our spillover variables (national pure spillovers, national rent spillovers and imports of machine tools), which were supposed to match the theoretical notion of spillovers used in these theoretical models have a positive but not a significant role when explaining R&D co-operation. The R&D co-operation increases with size and with R&D intensity, but not with market share. It also increases with the budget spent on paying license fees and on acquiring patents and labour from foreign firms. In this study, we also analyse the determinants of innovation. In more precise terms, we compare the effects of R&D co-operation to those played by traditional internal factors and those exerted by external, pure and rent spillovers on the innovation capacity of the firms. Our results show that the commercial success of innovations of French firms depends mainly on size, market share, R&D intensity and human capital. Inward FDI from industrialised countries exerts a positive and significant effect. The finding highlights the important role of the absorptive capacity of firms. Spillover measurements, such as the acquisition of machine tools, foreign patents, licenses, and technological opportunities have a positive impact on innovation. 相似文献

Prior research has extensively studied FDI spillovers on broadly defined technological innovation but offered inconclusive evidence. Relatively little is known about how the knowledge characteristics of local technological development are shaped by FDI and the innovation context where this development takes place. We therefore study the influence of FDI presence on host country firms' technological progress with a focus on two factors: the underlying technological characteristic, complexity, which reflects the difficulties in recombining diverse knowledge combination for innovation, and an under-studied contextual contingency: the local clustering of returnees (skilled returned migrants) that creates different interactive environments for incorporating foreign knowledge. Using a unique sample of 35,376 firms over an 11-year period in China's equivalent of Silicon Valley, Zhongguancun, we reveal that FDI exerts a curvilinear spillover effect on local firms' technological complexity. Furthermore, we find returnees' clustering in related sectors heightens the effect of FDI spillovers on local technological complexity, whereas unrelated sectoral clustering flattens this U-shaped relationship, reducing FDI spillovers. We add to the debate on FDI knowledge externalities by highlighting the importance of considering knowledge characteristics and the contextual setting of returnee clustering in understanding FDI spillover effects on local technological progress. Theoretical and practical implications are discussed. 相似文献

Knowledge spillovers across economic agents are central to the process of technological innovation. Yet, the mechanisms by which spillovers travel and manifest as innovation are poorly understood. To fill that gap, we study how knowledge spillovers emanating from other cities (knowledge pools) diffuse and get absorbed. We refine the notion of connectedness by comparing three mechanisms through which knowledge spillovers occur between cities (geographically, technologically, and socially via social media links). We also examine how local psychological openness facilitates this diffusion and absorption process. Using 360 U.S. cities as our empirical context, we find geographically mediated and socially mediated (but not technologically mediated) knowledge spillovers to show positive relationships with the rate of patenting. Moreover, results confirm a positive moderation effect of psychological openness on the relationship between socially mediated knowledge spillovers and the rate of patenting. By providing a more comprehensive test of knowledge spillover mechanisms, our study indicates that the often-quoted physical proximity to knowledge pools remains a robust driver. However, a city's virtual connection to knowledge pools (e.g., via social media links between people) also matter, particularly if that city is psychologically more open. This catalyst of local openness might occur because open populations better absorb inflowing knowledge and utilize it more effectively via key innovators. We discuss implications for research and policy with a particular focus on virtual human (vs. geographically bounded) connectedness and psychological openness as intertwined key areas of a new human geography of innovation. 相似文献

用创新知识产出和创新经济产出分别衡量区域创新绩效,运用空间计量模型实证考察创新资源流动对区域创新绩效的影响以及金融集聚在其中的调节作用。结果表明,创新资源流动对区域创新绩效具有显著促进作用并能产生正向的空间溢出效应;金融集聚正向调节创新资源流动与本地区创新知识产出的关系,但对创新资源流动与邻近地区创新知识产出的关系具有消极作用;当用创新经济产出衡量创新绩效时,金融集聚对创新资源流动与本地区创新经济产出关系的调节作用不显著,对创新资源流动与邻近地区创新经济产出的关系表现出显著的负向调节作用。 相似文献

本文利用我国1985-2005年省际面板数据,构建门槛模型实证分析外商直接投资(FDI)技术溢出及其区域创新能力“门槛效应”。研究表明：FDI技术溢出在我国存在显著的创新能力“双门槛效应”;1987年以来,我国大部分省份已进入中等创新能力区域,FDI的流入对这些省份都存在显著的正溢出效应,但由于还未进入高创新能力区域,这些省份对溢出效应的吸收还不够充分。这为我国坚持实施“以市场换技术”战略,努力提高区域创新能力以充分发挥FDI对技术的促进作用提供了实证支持。 相似文献
