基于随机前沿生产函数构建的区域知识溢出模型,实证分析了中国省区层面的外资R&D空间溢出效应及其差异。结果显示,我国外资R&D活动不仅对本省存在溢出影响,对邻省亦有重要贡献;东部省区同时受益于其东、中部邻省的外资R&D溢出效应,但中西部省区均只从同一区域且邻近省份的外资R&D活动获益。研究还发现,我国三大区域内部均已结成紧密的省际空间联系,外资R&D双向溢出显著;但东部与中部省区的空间关联度不强,外资R&D呈单向溢出格局;而中部与西部之间目前仍存在明显的空间分割特征,造成彼此之间互无溢出。 相似文献

运用偏最小二乘法（PLS）构建结构方程模型,将多维邻近整合到统一的研究框架,分析地理邻近对跨区域产学研协同创新绩效的影响。结果显示：地理邻近是多维邻近的第一维,其他邻近都是在地理邻近的影响下作用于产学研协同创新绩效;社会邻近虽然正向作用于技术邻近和关系邻近,但是不能间接通过技术邻近和关系邻近正向影响产学研协同创新绩效;制度邻近和关系邻近对产学研协同创新的影响很显著。为了实现科技资源优化聚集,有必要加快制度、市场和基础设施的一体化建设。 相似文献

中国东部地区向中国内陆及周边国家的产业转移方兴未艾,很有可能发展成为全球第四次产业转移浪潮,而制造业的区域转移是该过程的主体。本文对中国制造业不同尺度的份额变化及其影响因素进行讨论并对二者关系进行计量分析,得出以下结论:第一,制造业重心基本空间格局未发生变化,但已发生明显的份额变化;第二,制造业份额变化涉及多个空间层面,并遵循随经济发展水平增长而降低的梯度原则;第三,根据2001年和2009年中国地市级尺度制造业份额变化及其影响要素间关系的理论分析和计量研究结果,中国区域制造业份额与经济发展水平呈现倒U型关系,且仍对低成本劳动力具有一定的依赖性,而交通设施改善对于制造业份额的增长具有显著的正向效应。 相似文献

探究不同尺度下知识密集型制造业的集聚特征及其形成机制。结果显示：①计算机行业的集聚强度最高,京津冀各行业集聚强度高于长三角和珠三角地区;②城市群尺度各行业多集中在100 km范围内,京津冀呈现“核心—边缘”结构,长三角为“扇形”结构,珠三角具有“多核心”特点;③城市尺度大部分行业集中在40 km范围内,少数行业在边缘区集聚,京津冀表现为“蔓延型”集聚,长三角为“局部型”和“多中心型”,珠三角为“多中心型”;④城市群尺度上的集聚特征依据地区资源禀赋和比较优势,城市尺度上的集聚特征则依生产成本上的空间差异、产业政策和地方保护主义等因素二有所不同。 相似文献

我国制造业的空间重构不仅表现为整体格局和职能强度的变化,更体现在内部构成要素的分化上。我国从事制造业的正规与非正规从业人员比例由2000年的41.7:58.3转变为2010年的29.3:70.7。两者的空间结构差异明显,非正规就业密度由沿海向内陆逐步递减,而正规就业在内陆省会城市存在明显高地。本文分析了制造业重构过程中的六类城市及其分布变化。研究表明,全球化进程和就业门槛显著促进了非正规就业增长;非正规就业也与经济发展存在共生关系,但与制度环境并无显著关联;此外廉价劳动力、市场可达性与规模经济对制造业的区位选择具有显著影响。 相似文献

在知识获取途径极其多样和便捷的今天,美术馆、博物馆的知识生产和文化传播使命对策展提出明显的新要求。美术馆和综合性博物馆的绘画展在朝各自擅长的领域进发并担任不同方向公共教育责任的同时,也在一个大的社会环境中经受检验后向彼此学习。这类绘画展在保持自己独有气质的同时,发挥美育功能,并有意识地开拓文化挖掘和文化传播功能,形成\"强策展\"趋势。\"强策展\"理念对于当今绘画展策展的意义重大,也对策展人提出更高的艺术专业素养要求。他们须同时是合格的艺术批评家、具有创新思想的创作者、艺术传播专家等。未来展览界将出现深具历史眼光和前瞻性的\"展览的展览\"以及专业中立、理性辩证的\"展览批评\"。 相似文献

Covering the knowledge economy scenario, this article attempts to illustrate the analysis of the employment of knowledge transmission channels in the EuroClusTex, cross-border textile and clothing cluster between northern Portugal and Galicia. Therefore, an exploratory research was conducted. Primary data were obtained through participation in events, from interviews with key informants (entrepreneurs, leaders of cluster support institutions and government representatives). The secondary data were provided by the cluster support institutions, international organizations and the literature review. The results showed that EuroClusTex contributes to the competitiveness of regions, boosting trade relations between Galicia and northern Portugal. The most effective knowledge transmission channels in EuroClusTex were identified as: imitation, relationship with suppliers, public policy and human resources training. Experiences similar to EuroClusTex can be considered and served as examples for the development of clustering policies in other countries. 相似文献

Innovation is increasingly considered a prerequisite for regional development and it is commonly understood that certain regions are more conducive to innovation than others. Regions that do not possess the required institutional and cultural contexts are often encouraged to work on creating them. However, there is increasing evidence that innovation is also a spatial phenomenon: the propensity of establishments to innovate also varies with their location relative to major and minor metropolitan areas, independent of local context. This article investigates whether the geography of innovation is similar for three different types of manufacturing sectors ( high-tech (HT), medium-tech, first and second transformation) and across two different types of innovation (product, process). It is shown that, in Québec, to the extent that geography and innovation are connected, it is principally distance from a metropolitan area that plays a role. Our results lend support to McCann's (2007) recent spatial model of innovation and are also compatible with Duranton and Puga's (2003) theory of nursery cities. Our results also show that HT innovators behave differently from other manufacturers, with a tendency to internalize their innovation behaviour (perhaps out of necessity or for reasons of secrecy) in more distant locations. 相似文献

Fostering place-based innovation and internationalization – the new turn in German technology policy
Since the mid-1990s German technology policy has experienced a paradigmatic shift from standard grant schemes towards a region-oriented and competition-based R&D policy. Currently, a new policy experiment, the InterClust contest, is under way, trying to simultaneously foster place-based innovation, R&D internationalization and the internationalization of innovative places. The current paper analyses the new policy, relating it to the recent literatures on heterogeneous firms and on cluster-life cycles, and presents results from a firm survey performed in 21 winner regions of InterClust. Findings show that the new funding scheme takes insights from recent theoretical developments into account and addresses important impediments to firm and cluster internationalization. Although it is too early for an overall assessment, it is argued that the long-term impact will critically depend on the inflow of heterogeneous knowledge and the strength of intra-regional mobilization effects. 相似文献

We test whether there is a link between the performance of universities, measured through a concept of efficiency, and the economic development of the regions in which they operate. Indicators of teaching, research, and third mission are considered as outputs. To handle endogeneity problems between the efficiency of universities and economic development, a system generalized method of moments and then an instrumental variable approach are used. Our findings reveal that the presence of efficient universities fosters local economic development. Knowledge spillovers occur to areas that are in close geographical proximity to efficient universities. Results are robust to different estimation strategies. 相似文献

Enhanced transportation infrastructure improves the frequency of travel and facilitates face-to-face communication. Will the resulting reduction in travel cost mitigate the geographical concentration of knowledge spillovers? Our empirical strategy exploits China's mass expansion of its intercity high-speed railway network as a natural experiment. Using patent citations as the proxy for knowledge spillovers, we find inventors increasingly rely on more distant knowledge after rail connection and newly connect cities' innovation performance improves substantially. 相似文献

Knowledge intensive services (KIS) have grown rapidly across Europe in recent years and are often regarded as critical to economic growth and knowledge diffusion. This paper focuses on the factors determining spatial variations in the growth of these services. Combining insights from the regional innovation systems approach and modern growth theory, it is argued that local economic diversity may be beneficial to the growth of KIS. An empirical study of Great Britain over the period 1991–2002 reveals significant regional variations, with rapid growth occurring in a central cluster and major urban areas. The results of an empirical model provide support for the positive impact of diversity on employment growth but no evidence of a positive effect of sector specialisation. From a policy perspective, the analysis suggests that greater attention needs to be devoted to enhancing economic diversity and understanding sector specific effects. 相似文献
