[目的/意义]深入理解技术知识流特征将对提升企业创新绩效和重塑产业竞争格局意义重大。然而,传统的研究方法不能表示技术知识流的方向、难以分析由方向性带来的非对称矩阵。[方法/过程]通过区分专利主、副分类号的差异,将共类矩阵转化... [目的/意义]深入理解技术知识流特征将对提升企业创新绩效和重塑产业竞争格局意义重大。然而,传统的研究方法不能表示技术知识流的方向、难以分析由方向性带来的非对称矩阵。[方法/过程]通过区分专利主、副分类号的差异,将共类矩阵转化为表征知识创造和技术应用指向性的技术知识流(TKF)矩阵。在此基础上,提出了4项测度技术知识流特征的指标及应用途径:技术扩散(TD)、技术吸收(TA)、技术绝对影响(TAI)和技术相对影响(TRI)。[结果/结论]最后,基于德温特创新索引(DII)采集的4G专利,描述了4G产业技术知识流特征,并识别出知识生产者、技术应用者、活跃者和贡献者角4类角色。 展开更多

Based on patent cooperation data,this study used a range of city network analysis approaches in order to explore the structure of the Chinese city network which is driven by technological knowledge flows.The results revealed the spatial structure,composition structure,hierarchical structure,group structure,and control structure of Chinese city network,as well as its dynamic factors.The major findings are:1) the spatial pattern presents a diamond structure,in which Wuhan is the central city;2) although the invention patent knowledge network is the main part of the broader inter-city innovative cooperation network,it is weaker than the utility model patent;3) as the senior level cities,Beijing,Shanghai and the cities in the Zhujiang(Pearl) River Delta Region show a strong capability of both spreading and controlling technological knowledge;4) whilst a national technology alliance has preliminarily formed,regional alliances have not been adequately established;5) even though the cooperation level amongst weak connection cities is not high,such cities still play an important role in the network as a result of their location within ′structural holes′ in the network;and 6) the major driving forces facilitating inter-city technological cooperation are geographical proximity,hierarchical proximity and technological proximity. 展开更多

In the era of over communications and hyper concurrency, people are overloaded with the offer of information, ideas, products, and services. Information is easy and unbelievable prompt available all over the world. Customers, concurrency, and innovators have immediate access to each other changes in technology, especially those in informatics and technology of communication are transforming the era of informatics to the era of knowledge. The aim of this paper is to make an overview of the most up-to-date novelties in technology, especially those that were enabled by ICT, as well as to direct to some of the potential of the future evolution in business process that is open to the innovations. 展开更多

French was then recognized as the official language in administration. Iranian migration later took on another dimension after the 1953 Coup, a politicization that reached a peak with the arrival in Paris of Khomeini on August 2, 1978. In spite of this migratory tradition, about 4,000 persons before the revolution, the majority being from the political and financial elite, these migratory flows amplified in the middle of the 1980s, in such a way that at the end of December 2014, there were 31,000 Iranians in France. This new phase which included four waves, from a sociological point of view, can be called the diasporaisation of Iranian migration. The socio-economic profile goes from the urban elite: lawyers, officials, journalists, teachers, doctors, nurses, magistrates, military officials, company directors, political exiles, etc., to artisans such as shopkeepers, garage owners, building contractors.., and finally from the skilled labourer, on through to unskilled workers in building, restauration or removals, 展开更多

The knowledge accumulation through knowledge acquisition and technological learning is a necessary condition for enterprise upgrading in global chains.The knowledge flow obstacle caused by the knowledge barriers is the major reason for low-locked in the global value chain based on the analysis of knowledge flow,where standard is one of the most cmmonly used knowledge barriers.In this regard,a standard strategy based on similar technology development can be adopted to step over knowledge barriers and achieve upgrading. 展开更多
