采用专利跨国引用作为国际性技术外溢的代理变量,基于美国国家经济研究局专利引用数据库分析中国发明专利技术的现状和特征;依据该数据库中6大类36个专利的细分类别,计算1985年～1999年中国与11个创新型国家(地区)的技术相似度;运用技术知识存量替代技术知识流量,测算中国1985年～2004年的对外技术依存度,综合分析技术相似性、对外技术依存度、地理距离和语言等因素对中国通过专利引用获取国际性外溢技术的影响,利用负二项回归方法对影响中国专利引用的相关因素进行计量研究.研究结果表明,技术相似度与跨国专利引用之间不存在显著性正相关关系,对外技术依存度、语言差异均与跨国专利引用显著负相关,地理距离与跨国专利引用显著正相关.
採用專利跨國引用作為國際性技術外溢的代理變量,基于美國國傢經濟研究跼專利引用數據庫分析中國髮明專利技術的現狀和特徵;依據該數據庫中6大類36箇專利的細分類彆,計算1985年～1999年中國與11箇創新型國傢(地區)的技術相似度;運用技術知識存量替代技術知識流量,測算中國1985年～2004年的對外技術依存度,綜閤分析技術相似性、對外技術依存度、地理距離和語言等因素對中國通過專利引用穫取國際性外溢技術的影響,利用負二項迴歸方法對影響中國專利引用的相關因素進行計量研究.研究結果錶明,技術相似度與跨國專利引用之間不存在顯著性正相關關繫,對外技術依存度、語言差異均與跨國專利引用顯著負相關,地理距離與跨國專利引用顯著正相關.

This paper uses patent international citation as proxy for international technology spillover. Firstly, according to the pa-tent citation data base of National Bureau of Economic Research, this paper analyzes current situation and characteristic of inven-ting patent technology in China. Based on 36 patents of 6 major categories within the data base, this paper calculates the technol-ogy proximity between China and 11 innovation-type countries (regions) from 1985 to 1999. Secondly, this paper calculates for-eign dependence of technology of China from 1985 to 2004 by substituting technology knowledge stocks for technology knowledge flows; Moreover, this paper synthetically analyzes factors that influence technology proximity, such as technology proximity, for-eign dependence of technology, geographic distance, and language, etc. Finally, with the method of Negative Binomial Regres-sion, a quantative research is carried out to explore the relevant factors that affect patent citation of China. The results show that: there is no significant positive correlation as predicted between technology proximity and patent international citation; patent in-ternational citation is negatively related to both foreign dependence of technology and language differences, and these correlations are significant; patent international citation is positively related to geographic distance, and the correlation is significant.
