摘　　要：基于跨城市边界合作申请的发明专利数据,对中国(不包括港澳台地区)跨区域合作创新现状进行了分析,同时提出城市知识创新辐射距离的概念和计算方法,进一步研究具有辐射效应城市的8个合作方向以及不同行业的辐射距离。结果显示知识创新辐射距离随着地理距离增长呈递减趋势,且不一定与该城市信息流量成正比;北京、上海、深圳3个城市起到一定的技术创新"辐射和带动"作用;一些城市存在对某些方向地区"带动"作用的忽视;在不同的行业中,城市知识创新辐射距离体现出不同的特征。Based on the cross-city cooperation-patent application data,intensive research has been carried on the cross-region innovation cooperation in China（excluding Hong Kong,Marco and Taiwan）.A new concept,innovation radiation distance,is raised and the corresponding calculation method is also introduced and applied on the selected samples to find out the radiation distances for each city and each industry.The results show that the innovation radiation distance has a negative correlation relationship with the geographic distance and no apparent evidence of positive impact from the information flow amount can be identified either.Nevertheless,the radiation transmission is not universal to all directions and some areas on the radiation periphery feel feeble impact.Moreover,different industries cannot be described by an overall radiation distance rule.The outcomes can be summarized as below：1）The innovation radiation distance does not grow proportionally with the patent amount.For instance,some cities,like Shenzhen and Chongqing,tend to find partners far away,though their cooperation-patent is relatively small.However,some other candidates say Shanghai and Hangzhou,are vice versus.2） The innovation radiation distance cannot be determined by the information flow alone.Some cities show greater incentives of cross-city innovation cooperation through frequent exchange and propagation of technology and knowledge,while other cities display a prominent regional confinement in information communication,which implies a huge potential for further improvement.3） Through the study of innovation radiation distance and range in eight factors on the selected sample,the article find out that Beijing has a profound radiation effect over the whole country,which is unparalleled for other competitors,though the equality of radiation should be attached more attention by putting more weight to the western region.Three cities,Shanghai,Nanjing and Hangzhou,constrain themselves to the pan-Changjiang River delta region and show infinit
