We consider a three-location duopoly model such that (i) firms choose production and innovation locations before (Bertrand) competition takes place and (ii) there are internal and external knowledge spillovers. We show: (1) agglomerations where firms earn negative profits may exist when there are both external and internal knowledge spillovers; (2) greater external spillovers do not necessarily favor agglomeration; (3) decreasing communication costs tend to favor agglomeration; (4) there are exactly two types of agglomeration equilibria: either both firms innovate in the agglomeration, or there is an innovator and an imitator; and (5) if there is a location where both firms produce, then innovation must take place in this location.  相似文献

We present a dynamic model of factor demands based on expected discounted costs minimization. While making only very mild assumptions on expectations and technology, we are able to establish a duality relationship between contemporary factor demands and the technology, and we provide formula for easily recovering marginal products, returns to scale, and technological change from estimated factor demands. Parametrization and implementation are illustrated in a detailed example.  相似文献

中欧贸易与欧盟技术性贸易壁垒   总被引:1,自引:0,他引:1  
近年来,技术性贸易壁垒(TBT)已成为发达国家实施贸易保护主义更为隐蔽、更为有效的手段.作为中国第三大贸易伙伴的欧盟,其实施的各种TBT措施对中国的出口产品产生了严重的影响.因此,必须建立欧盟技术性贸易壁垒预警机制,时时监控其新动向;坚持"以质取胜"的原则,大搞技术创新和产品创新,以更高的产品质量标准和专利注册超越其贸易壁垒.  相似文献

随着人民币国际化进程的逐步推进,SDR货币篮子中人民币的国际化定位引人瞩目。本文基于非线性MSBIARCH模型,实时甄别人民币市场与美元市场、英镑市场、日元市场、欧元市场之间的波动传染关系,以及波动传染作用下汇率市场的波动聚类态势,进而识别SDR货币篮子中人民币的国际化定位,旨在为及时防范并规避人民币市场的波动风险提供参考。研究发现,汇率市场经由"经济基本面""市场情绪"以及"市场预期"对外发挥波动传染作用,人民币市场与美元市场之间存在双向波动传染关系,与英镑市场、欧元市场以及日元市场之间存在单向波动传染关系。不同汇率市场之间的波动传染关系表现出时间区制转移特征,汇率市场的波动聚类态势也呈现时变特征。汇率市场发挥波动传染作用的时间与汇率市场呈现波动聚类态势的时间相匹配,均集中在极端经济事件期、不规则事件期以及政策颁布事件期。国际汇率市场的波动传染作用导致了人民币市场的波动聚类态势,而人民币市场的波动传染作用仅强化了国际汇率市场的波动聚类态势,SDR货币篮子中人民币的国际化程度有待进一步提高。  相似文献

The past decade has witnessed dramatic social and political changes on the African continent. The present article argues that these political and social changes may spill over in the workplace in the form of a quest for justice and empowerment. Based on the organizational justice literature, the article develops a conceptual framework that advocates the integration of justice concepts in managing African organizations. It also explains how African managers can anticipate this trend by developing and implementing fair organizational practices.  相似文献

This paper analyses the relationship between OECD countries'business sector total factor productivity and domestic and foreignR&D efforts during the period 1961-1991. A sensitivity analysisis performed by making use of alternate estimations of specificationsin growth terms and in level terms. The results are shown tobe robust. They show that the influence of international technologicaldiffusion is, on average, substantially stronger than that ofdomestic R&D. In the case of the large economies, however,the latter influence is found to be more important. A structuralstability analysis provides evidence of a decrease in the estimatesin the mid-1970s, without significant recovery afterwards. Variouslong-run supply effects appear to have contributed. The discontinuousnature of the reduction does indicate, however, that these werereinforced by macroeconomic disturbances at the demand side.  相似文献

Innovative profits (of the kind conceptualized by Schumpeter) are today being increasingly created through international corporate networks for technological development. Such profits through innovation are encouraged by newer more flexible organizational forms, and further encouraged (unlike in the conventional perspective on profits and on the incentive to innovate) by knowledge flows between firms. Our empirical evidence, based on US patent data, shows that multinational companies are currently more likely to develop abroad technologies which are less science-based, and less dependent upon tacit knowledge. However, within the science-based industries firms may generate abroad some technologies which are heavily dependent on tacit knowledge, but normally in fields that lie outside their own core technological competencies. We find some evidence of a convergence in corporate technological diversification across large firms, facilitated by the now common spread in the use of information and communication technologies (ICT) as an integrator of formerly separate technological systems. This has led smaller firms to diversify, but giant firms to consolidate activity around those technologies that have become most interrelated.  相似文献

提高高新技术企业技术创新能力的对策研究   总被引:1,自引:0,他引:1  
高新技术企业是属于知识聚集和技术密集的企业,提高企业自身技术创新能力是高新技术企业赢得竞争优势的关键,更是推动高新技术企业走向快速发展的必然途径。本文系统的分析了技术创新对高新技术企业的重要意义,从外部大环境和企业内部自身环境所存在的不足而导致高新技术企业技术创新过程所存在的问题进行了客观的分析,列举了外部环境和内部环境在高新技术企业中所出现的具体问题,同时针对不同的问题提出了相应的解决对策并作出了有益的探讨,为高新技术企业技术创新的研究提供一定的理论研究,为高新技术企业走向高级化发展提供了借鉴经验。  相似文献

Whereas new product development (NPD) speed and product innovativeness are two critical strategic determinants of firm performance, previous studies show inconclusive findings about their effects. Drawing on institutional and contingency perspectives, this study elucidates value appropriation issues in NPD and examines how the effects of NPD speed and technological radicalness are contingent on institutional frameworks and market conditions. Results from 244 high-tech companies in China show that dysfunctional competition enhances the effect of NPD speed, but legal inadequacy hinders the impact of technological radicalness on firm performance. Market growth strengthens the performance effect of NPD speed but restrains the effect of technological radicalness. In addition, technological radicalness demonstrates stronger effects on firm performance when demand uncertainty is high.  相似文献
