Decline of the center: The decentralizing process of knowledge transfer of Chinese universities from 1985 to 2004

University knowledge transfer, which contains both codified and non-codified knowledge, is an important source of industry innovativeness. The geographic constraint on university knowledge flows, which is commonly observed in Western countries, makes proximity with universities a big plus in creating learning regions. No systematic study has been conducted in China regarding such geographic constraint on knowledge transfer and its implications on China's nation and regional innovation systems. Taking advantage of the Chinese patent data, this paper examines the geographic variations in university-industry collaborations in China from 1985 to 2004 and shows a decentralizing/localizing trend in knowledge flows from university to industry. The blockmodel analysis further reveals the roles of different provinces and municipalities in the National Innovation System and how those had changed over time. Besides showing a vivid picture of the knowledge exchange patterns among Chinese provinces and municipalities, the results suggest that the geographic constraint on knowledge flows only becomes salient in China in recent years due to the administrative decentralization and the economic reform. As a result of these changes, less favored regions are further left behind not only due to their shortage of local university resources, but also because of the reduced extra-local knowledge support, which constitutes an important supplemental resource for regional development.     

First-mover advantage and the private value of public science

Technical progress increasingly relies on the use of scientific knowledge. But if much of this knowledge is in the public domain, can it be a source of private value? We find that average private returns to using public science are small, especially in crowded technical fields. This is consistent with the view that the expected profit from an input that competitors can easily access is low. However, private value is higher when a firm is the first to use science, partly because it can secure broader patents relative to later users. Corporate participation in scientific research is a strong predictor of first use, consistent with the view that participation in science raises familiarity with relevant scientific advances.     

论文被引频次离散系数对影响因子影响机制研究

[目的/意义]探讨期刊论文被引频次离散系数与影响因子的关系有利于深化文献计量研究,对于学术期刊评价也具有积极意义。[方法/过程]以CSSCI经济学期刊为例,基于中国知网的引文数据库,采用回归分析研究了两者之间的关系。[结果/结论]论文质量差异是期刊论文被引频次离散系数差异的原因;期刊论文被引频次离散系数与影响因子负相关;期刊论文被引频次离散系数与影响因子之间呈U型曲线;条件成熟时可以将期刊论文被引频次离散系数作为期刊评价指标;对于其他学科期刊论文被引频次离散系数与影响因子的关系有待进一步研究。     

基于专利分析的全球光纤激光器产业技术研究

揭示全球光纤激光器产业技术发展现状,为中国光纤激光器产业技术发展方向提供参考。基于近10年的专利数据,从专利申请态势、区域竞争力、研发机构实力、热点研究领域等角度揭示全球光纤激光器产业技术的研究进展。近10年中国光纤激光器专利技术高速发展,产业前景广阔,但研发机构整体缺乏海外布局意识;高功率光纤激光材料与器件、特种光纤、光纤耦合技术、光纤激光加工技术是当前光纤激光器技术研发热点,未来可重点关注超快激光光速合成、光纤激光非线性效应调控等技术领域的研发动向;产业上游核心元器件的研发能力不足,光纤介质、高功率泵浦源芯片、高功率光纤光栅等核心元器件技术壁垒有待突破。     

企业专利申请类型的影响因素探析——来自中国工业企业的实证研究

基于中国工业企业微观数据考察了企业专利申请类型的选择,在此基础上构建bi-probit模型,深入分析规模、产业竞争及研发投入对企业专利申请类型的影响,研究发现,企业规模和产业集中度促进了企业的发明专利和实用新型专利申请,且对发明专利的影响更大;研发强度促进发明专利的申请,但与实用新型专利申请负相关。在此基础上提出企业专利战略选择和我国专利制度改革的政策建议。
