The article analyses how a technical knowledge field ('antenna technology') is developed and exploited in a region (West Sweden). To identify regional actors, the paper outlines a way of delineating a technical knowledge field and its changes over time. Drawing on this, an historical account is given of the international and the regional development, focusing on the changing and expanding nature of industries and markets (from military to civilian applications) and technologies. The paper emphasizes the long regional history, providing experience, which together with a number of diversifications, has given regional actors a platform from which to exploit the growing economic utility of the technical knowledge. It is also shown why some applications have not been exploited in the region.  相似文献

Based on the empirical findings achieved through comparative research involving 40 innovation policy instruments from 11 European regions, this paper proposes a shift in rationale and in the broad orientations of innovation policy to focus on addressing SMEs in their regional context. The main role for innovation policy, which aims to increase the capacity of a region and the capabilities of its SMEs to innovate, is to foster interactive learning within the firms and within the region. This calls for an interactive mode of policy intervention. The paper deals also with the question of how to build a coherent portfolio of policy instruments, taking into account both regional situations and specific SMEs needs in terms of innovation. The key message is that there is no 'one-size-fits-all' policy portfolio. Regional differences in innovation capabilities call for a tailored mix of policy instruments. One salient element of the conclusion is the need for more 'policy intelligence' in this complex field.  相似文献

Interactive approaches to technology development provide opportunities for the development of innovative technologies which clearly connect with social practices and address the positive and negative effects as perceived by relevant actors. The challenge is to start an interactive approach early in the development of new technologies, when many options are still open for exploration and there are good possibilities for steering. Early involvement of societal actors is, however, challenged by the absence of concrete applications on which they can develop their own visions from the perspective of their own needs, interests, norms and values. Integrating Constructive Technology Assessment (CTA) with vision assessment is proposed as an approach to overcome this dilemma in the field of ecological genomics and bridge the knowledge gap between parties closely involved with ecogenomics research and other relevant actors. We present, evaluate and discuss the process of identifying guiding visions of the technology developers as a first step in this approach and end with some suggestions on how desirable futures for ecogenomics can subsequently be assessed from the perspectives of different actors.  相似文献

The creation of new knowledge is a case in which agents' behaviour can affect the performance of other actors positively, given that new knowledge creates positive externalities in the market. In this context, we investigate the existence of performance spillovers associated with innovation activities by quantifying the innovation produced in surrounding firms and controlling for the fact that a firm is itself an innovation producer. We use data from the Third Community Innovation Survey (CIS III) that measures innovation in a broad way, not reducing it to R&D and patents, which departs from previous literature on spillovers. Furthermore, to tackle the endogeneity of the innovation variables on the firm production decision, we resort to the firm intellectual property protection methods as an instrument. We found a positive spillover of innovation on firm value added. The results also show that process innovation spillovers are more prevalent than product innovation spillovers.  相似文献

中国区域知识复杂性测度及其对创新的影响   总被引:2,自引:0,他引:2  
十九大报告明确提出,创新是引领发展的第一动力,是建设现代化经济体系的战略支撑。知识作为创新的核心驱动力,其重要性受到众多学者的关注。基于伊达尔戈等的HH反射方法,利用15 988 864件中国专利数据,测度中国内地31个省市区知识复杂程度,并检验其对创新产出的影响。结果发现:①虽然东部地区的稀缺技术掌握能力高于中、西部,但中、西部地区落后境况不断改善,正逐渐进入新的技术领域;②知识复杂性对创新高效区域(东部)的影响更大,但低效地区(中、西部)具有更高的稀缺知识边际增益。以上发现的政策含义是,区域不应仅谋求单一领域内的竞争优势,应以兼顾聚集多样化和高质量知识为最终政策目标。  相似文献

Recent analysis on New Regionalism has, for Björn Hettne, raised important ontological questions over ‘what we study when we study regionalism’. The paper contributes to this debate by focusing on the shared beliefs, norms and rituals that hold a region together. Working between the New Regionalism literature and thinking on international regimes, this paper – to paraphrase Friedrich Kratochwil and John Ruggie – outlines the ‘inescapable inter-subjective quality’ of a region. This focus on inter-subjectivity seeks to improve on existing approaches that consider shared social structures as already fixed, and/or as autonomous constructs operating over and above regional actors. In order to appreciate how inter-subjective structures and regional agents interact with each other, the paper explores the social construction of Latin America. Specifically, it examines the politics of regionness – understood here in relation to identity, space and agents – to demonstrate how various regional actors operate within, and reconstruct, shared meaning. In so doing, it interrogates the practices that govern and continually produce the region.  相似文献

基于空间网络视角,利用联合专利数据刻画我国产学研协同创新网络演化特征。研究发现,随着产学研主体不断增加,创新网络逐渐覆盖全国,但区域创新联系呈现出创新中心区与非中心区非均衡性。由于空间网络关系的路径依赖越来越明显,技术知识传递的非对称性分布加剧,协同创新活动呈现创新中心区位锁定,导致网络协同创新效应难以形成,整体上协同创新网络重心呈“单核”向“三核”分布格局演化,国家创新系统长期依赖少数中心区域,中心区域技术知识辐射的局部效应与区域平衡发展的矛盾不断凸现。因此,应合理配置创新资源,优化协同创新网络空间形态,推进国家创新系统向均衡创新生态系统演化。  相似文献

This paper uses household-level datasets called Chinese Household Income Project (CHIP) surveys to investigate the regional technical efficiency, technology gap, and their determinants in rural China. A metafrontier production function approach is employed to fit the values of the technical efficiency and the technology gap ratio of rural households in six regions of China. The findings indicate that the technical efficiency improved remarkably from 1988 to 2002, but the technology gap ratio among regions changed slightly in the same period. The findings also show a negative relationship between the technology gap ratio and the regional technical efficiency for all regions except the northwest that has the lowest value of both the technical efficiency and the technology gap ratio. Next, the Tobit model is employed to discern the sources of efficiency and technology gaps. The results show that quality of agricultural labor, agricultural infrastructure, natural conditions, and farmer's political status have significant effects on farms' technical efficiency and technology gap ratio.  相似文献

If cumulativeness is one feature of knowledge as economic good [Foray, D. 2006. The Economics of Knowledge. Cambridge, MA: The MIT Press], one may wonder why knowledge produced in a given sector does not result in several applications thorough the whole economy. Therefore it is important to understand the dynamics of knowledge that helps a given piece of knowledge to overcome sectorial silos and become more transversal. Here, focusing on Drones, patents analysis reveals how different technical systems use or do not use the same knowledge to solve identical issues or needs. This paper offers three major advantages. First, it allows distinguishing between component knowledge linked with technological bricks and architectural knowledge linked with system integration. Second, it opens new possibilities to measure the transversality of knowledge or its duality (beyond the debates in defense economics). And finally, it offers the opportunity to empirically analyse duality using patent databases.  相似文献

在知识经济条件下,贸易自由化能否对一个国家的产出水平产生影响,能否为国际经济带来收敛,这是一个重要问题。文章通过假设国家之间构成一个知识网络,贸易中存在非线性的知识溢出,模拟了单边或多边关税下调对一个国际经济增长的收敛行为。研究结果表明,进入WTO体系后关税下调并不总意味着收敛的出现,收敛性依各经济体的初始状态和学习能力的大小而出现复杂行为,在知识网络体系单元取向上,网络的溢出参数——学习能力是决定性因素。多区域系统一旦出现收敛,则不会以牺牲富国利益为代价,即收敛是以低水平稳态向高水平稳态转移的形式出现的。  相似文献

The aim of this paper is to compare different environmental policies for cost-effective habitat conservation on agricultural lands, when the desired spatial pattern of reserves is a random mosaic. We use a spatially explicit mathematical programming model which studies the farmers' behavior as profit maximizers under technical and administrative constraints. Facing different policy measures, each farmer chooses the land-use on each field, which determines the landscape at the regional level. A spatial pattern index (Ripley L function) is then associated to the obtained landscape, indicating on the degree of dispersion of the reserve. We compare a subsidy per hectare of reserve with an auction scheme and an agglomeration malus. We find that the auction is superior to the uniform subsidy for cost-efficiency. The agglomeration malus does better than the auction for the spatial pattern but is more costly.  相似文献

This paper examines the relation between industrial mix, trade, and regional productivity growth. For this purpose, a dynamic model of the open economy with diversified sectoral knowledge formation and incomplete interregional knowledge diffusion is constructed. The theoretical framework is first used to show the consequences of increasing globalization on regional growth. It is then applied to German regional data in order to investigate whether there is evidence of generally specified patterns of knowledge formation. It emerges that some causal relationships are robust for the case of German regions but cannot be exploited by economic policy in general.  相似文献
