IMPACT ON FIRMS OF THE USE OF KNOWLEDGE EXTERNAL SOURCES: A SYSTEMATIC REVIEW OF THE LITERATURE

This study summarizes the main conclusions from a systematic review of the empirical literature regarding the impact on firms of the use of knowledge external sources (universities, research institutes and knowledge intensive business services). With the aim to organize the literature, we classify the different works according to the research question addressed: (i) which firms use knowledge external sources?; (ii) Do firms using knowledge external sources achieve better results?; And (iii) which firms benefit the most from using knowledge external sources? Stylized facts are that larger, more R&D intensive and high tech firms are more likely to use knowledge external sources and that use of knowledge external sources is associated to firms higher technical results. Less attention has been paid to the third question and evidence is not conclusive. Several recommendations for future research emerge. First, to take in greater consideration methodological issues so that potential biases in the results caused by sample selection and endogeneity are handled properly. Second, to pay more attention to heterogeneous outcomes. Third, to use continuous indicators of depth and breadth of links allowing for non‐linear relationships and fourth, to extend evidence for developing countries and service industries.     

城市用地结构与产业结构关联的实证研究——以重庆市为例

城市用地结构与产业结构的有机耦合是提高城市用地效益,促进产业结构高级化和城市整体功能提升的前提和保障。文章利用比例变化指数和Granger因果法对重庆市城市用地结构和产业结构耦合关系的实证研究显示:重庆市城市产业结构变化滞后于城市用地结构变化,城市用地结构变化与产业结构变化的差距呈现先上升后下降的趋势,即重庆市城市用地结构与产业结构的有机耦合在经历了非同步变化后逐渐步入同步变化的轨迹;短期内,城市用地结构变化推动产业结构的优化,随之,产业结构又反作用于城市用地结构;城市用地结构和产业结构同步变化轨迹还没有出现,这说明城市用地结构与产业结构互为因果的关系应在长期的调整、协调中才能得以实现。     

旧城改造开发项目的容积率问题研究

随着我国城市化进程的加速推进,不断增长的城市人口与持续升级的功能需求,对现代城市的建设与发展提出了新的要求。旧城改造是提升城市形象和改善人民生活的有效手段。本文在阐述容积率相关概念的基础上,根据投入产出理论,提出了旧城改造容积率测算模型,分析了容积率与利润率之间的具体关系。旧城改造实施人员可据此提出适宜的旧城改造方案。最后,本文以重庆市某旧城改造地块为例,对其容积率进行了重新测算,提出相关规划改造方案。     

基于分形理论的特大城市新型产业空间发展演变研究——以广州商务办公空间为例

本文借助分形理论和集中指数测算,从街道和均一分析单元两种空间尺度对广州办公业空间集中与分散的演变趋势进行了定量研究。研究结果表明,无论是在街道还是在均一分析单元层面,广州商务办公空间的空间分维值呈逐渐上升趋势,广州商务办公空间的集中程度逐年降低,办公空间的空间垄断性已不明显,空间分散化趋势得到了确立。但集中指数仍然处于较高的水平,表明广州商务办公空间虽然出现了分散的态势,但总体上仍然处于集中阶段。     

住房保障对象划分研究

住房保障对象划分是住房保障体系建立的一个重要环节,通过借鉴国际经验,结合我国实际,依据住房消费收入比、房价收入比等指标,采用统计分组法与倒推法相结合的方法来划分识别城镇住房保障对象,得出我国现阶段城镇住房保障对象应涵盖城镇居民中的最低收入户、低收入户和中等偏下收入户,保障住房覆盖率为40%.对最低收入家庭和低收入家庭,应采用租金补贴方式;对中等偏下收入家庭,可采用租金补贴也可采用购房补贴方式,具体可由被保障对象自由选择.     

Knowlege networks for innovation in small Scottish software firms

This paper examines the emergence of small indigenous software companies in Scotland, focusing on the strengths and weaknesses of the region's socio-economic infrastructure as a foundation for innovative new business ventures. Following a brief review of some of the accepted wisdom on high-tech start-ups and regional economic development the paper provides some background information on the Scottish region, comparing new firms in the software industry with the foreign multinationals that dominate the local IT industry. A framework - the ‘sociotechnical constituencies’ approach - is then proposed that allows the author to examine networks of specialist knowledge that underlie new business development. Agglomeration effects and the influence of ‘clusters’ of complementary types of knowledge, expertise and innovative competencies at the regional level are at the heart of the analysis. The framework is applied to a sample of local firms, looking at how ‘learning’ via sociotechnical networks underlies their evolution. Policy-makers' attempts to boost the region's new business birth rate and promote the hoped-for ‘silicon glen’ effect are viewed in the light of the study's findings.     

A quintessential immigrant niche? The non-case of immigrants in the Dutch construction industry

Students of immigrant entrepreneurship show a distinct preference for ethnic concentrations. They focus on small entrepreneurship in sectors with large concentrations of immigrant businesses or on ethnic commercial precincts. This preference stems from practical and theoretical considerations. It seems that the study of such concentrations, or niches, is essential to the theoretical understanding of the structural determinants of small entrepreneurship and the processes of economic incorporation of immigrants. This paper challenges this orthodoxy. It argues that it is important to assess the factors and processes that positively and negatively affect the formation of niches. This argument is corroborated by an analysis of the construction industry in the Netherlands. According to Waldinger (1995: 577), ‘construction represents the quintessential ethnic niche’, but immigrants in the Netherlands did not carve out a niche. This exceptional situation can be attributed to a sector-specific configuration of social, economic and institutional processes.     

跨国快餐产业采用成组产品战略对于消费者购买意愿影响之研究

本文针对跨国快餐产业中的成组产品进行分析,区分主要产品与次要产品的搭配模式与价格折扣方式,并透过统计分析与假设检定进行实证检验,以了解搭配模式与折扣方式对消费者购买意愿所造成的影响。实证结果显示:主次产品种类的搭配与价格折扣方式对于消费者购买意愿的影响是显著的,并且两个变量之间存在交互作用效果。此结论为垮国快餐产业在中国市场进行营销时采用成组产品战略提供了支持。
