【摘要】：科学研究是技术创新的基石。科研成果向产品技术转化的过程,也是知识扩散和吸收的过程。科技期刊文献和技术专利分别作为科学研究和技术创新的主要表现形式,已成为学者们进行知识扩散相关研究的有效工具。科技期刊文献到技术专利的知识扩散速度越快,企业在技术创新和知识产权方面的竞争优势越明显,对经济发展和社会进步越有利。揭示科技期刊文献到技术专利知识扩散的时间延时内在机理,挖掘知识扩散网络中的重要节点,对于完善知识扩散的研究理论,加快知识扩散的进程具有积极意义。本文从知识扩散的时间维度和空间维度出发,对科技期刊文献到技术专利的知识扩散展开研究。首先,提出技术专利的科技期刊文献引文的降噪处理方法,确保后续研究结果的准确性。首先通过分析专利引文的来源、引用目的及其作用,发现专利的科技期刊文献引文中存在和专利文献相似度较低引文数据,即引文噪声。因此,建立基于相似度计算方法的科技期刊文献引文降噪模型,然后收集多个领域的技术专利及其科技期刊文献引文信息,对专利及其引文信息进行相似度的计算,过滤掉相似度低的科技期刊文献,为后面章节的研究提供数据支持。其次,对科技期刊文献到技术专利知识扩散的延时过程进行计量研究。先对科技期刊文献到技术专利的知识扩散过程进行定性分析,并与科技期刊文献之间知识扩散的过程进行比较,揭示两者之间的相似性,提出利用科技期刊文献之间知识扩散的延时模型来描述科技期刊文献到技术专利的知识扩散延时过程的方法;进而用四种期刊引文分布模型对降噪后的专利引文时间分布数据进行拟合,找到最优模型,验证模型的适用性;通过对计算结果的分析,探讨了科技期刊文献到技术专利知识扩散的时间延时特点。然后在此基础上,考虑到从专利申请到授予是整个知识扩散过程中的重要阶段,本文继而对技术专利申请到授予的延时问题进行了定量研究,基于出版延时模型和威布尔分布建立专利授予过程的延时效应分析模型,以多个领域的专利数据为例进行计算和分析,找出制约专利授予延时的重要因素并提出相应的建议。再次,进行科技期刊文献到技术专利知识扩散关键节点挖掘的研究。从知识扩散的空间维度出发,通过技术专利对科技期刊文献的引用以及科研人员之间的合作关系,建立由技术专利的发明人和科技期刊文献的作者组成的知识扩散网络,对知识扩散网络中的重要节点进行挖掘和分析。构造基于Newman指标的广度中心度来挖掘对网络中子群之间知识扩散具有重要作用的节点。以合著网络为例,分析了该指标的优点。继而收集并整理了专利发明人及专利的科技期刊文献引文中的作者数据,建立发明人与学者之间的知识扩散网络,利用本文提出的新指标并结合比较常用的度指标来挖掘和分析对知识扩散有重要作用的节点,提出如何充分发挥关键节点桥梁纽带作用的建议,以保证知识扩散畅通无阻,促进科技期刊文献到技术专利的知识扩散。
[Abstract]:Scientific research is the foundation of technology innovation. The process of transformation of scientific research to product technology, is also the process of knowledge diffusion and absorption. Science and technology journals and patents respectively as the main form of scientific research and technological innovation, has become an effective tool for scholars of knowledge diffusion related research. Journal of Science and technology literature to technology patents the diffusion of knowledge faster, enterprises in technological innovation and intellectual property competitive advantage is more obvious, more favorable to economic development and social progress. Journal of science and technology literature to reveal the technology patent knowledge diffusion time delay mechanism, mining the knowledge diffusion of the important nodes in the network, for the study of theory of knowledge diffusion, has a positive speeding up the knowledge diffusion process. Based on the dimension of time and space from the knowledge diffusion, the science and technology journals to technology patents Knowledge diffusion is researched. Firstly, denoising method proposed technology patent citation technology, to ensure the accuracy of the results. The first through the analysis of sources of patent citation, reference purpose and function, found data in low similarity and patent literature citation literature Journal Citation of patent citation, namely noise. Therefore the establishment of scientific journals, citation denoising model calculation method based on similarity, and then collected a number of technology patents in the field of science and technology journals and citation information, the similarity calculation of patents and patent citation information, filter out low similarity to the science and technology journals, to provide data support for the research in the following chapters. Secondly, research the measurement of science and technology periodical literature to technology patent knowledge diffusion delay process. First to the science and technology journals to patent knowledge diffusion The process of qualitative analysis, comparison between literature and science journals and the process of knowledge diffusion, to reveal the similarities between the two, the time delay model of knowledge diffusion between scientific literature to describe the method of science and technology journals to patent knowledge diffusion delay process; and then use the four Journal Citation Distribution Model to fit the patent the citation time distribution of the denoised data, find the optimal model, verify the applicability of the model; the results of the analysis of the science and technology journals to patent knowledge diffusion time delay characteristics. Then on this basis, taking into account the grant from the patent application to the whole is an important stage in the process of knowledge diffusion, the the technology of patent application to delay awarded a quantitative study of the publication delay model and Weibull distribution, based on the establishment of patent granted Analysis of time delay effect of the process model, using patent data in many fields for example calculation and analysis, find out the important factors of restricting patent grant delay and put forward relevant suggestions. Thirdly, study of science and technology journals to patent knowledge diffusion of key nodes mining. Starting from the spatial dimension of the diffusion of knowledge, through the technology patent references to the literature journals and scientific research personnel relationship, to establish a network of knowledge diffusion consists of technical patent inventor and author of literature periodicals of science and technology, mining and Analysis on the knowledge diffusion of the important nodes in the network structure. The Newman index of mining center breadth of nodes on the network between the neutron group plays an important role in knowledge diffusion based on the co authorship network. As an example, analyzes the advantages of the index. Then collect and collate the patent inventor and patent technology The author in the journal citation data, the establishment of knowledge diffusion network between inventors and scholars, using the proposed index combined with the index commonly used to mining and analysis node on important knowledge diffusion, put forward how to give full play to the role of a bridge between the key nodes of suggestions, to ensure the knowledge diffusion smoothly, promote Journal of science and technology literature to patent knowledge diffusion.
