[目的/意义]从科研合作机构空间引力测度模型来分析合作机构间的合作联结强度，为进一步探究科研 合作提供新的思路，为有关部门调配科研资源、促进科研高质量发展提供智力支持。[方法/过程]以点度中心性表 征科研机构的科研实力，两机构间公路里程表示地理距离，在综合考虑科研实力和地理距离因素的基础上构建科 研合作机构空间引力测度模型，基于2016—2020年间410条国家科技进步奖获奖项目数据，使用Gephi软件计算 国家科技进步奖获奖项目合作机构点度中心性，同时根据机构合作共现矩阵查询机构间公路里程，计算科研合作 机构间的空间引力，据此构建科研机构合作联结网络，揭示机构合作联结态势。[结果/结论]机构跨地域科研合作 倾向越来越强，但地理距离对合作联结强度的阻碍仍不可忽视。为推动产学研合作高质量发展，提出如下建议： 推动跨地域科研合作深入发展；设计科学合理的科研人员流动机制；合理调配科研资源。

[Purpose/significance] To analyze the cooperation connection strength between cooperative institutions from the spatial gravity measurement model of scientific research cooperative institutions, so as to provide new ideas for further exploring scientific research cooperation, and provide intellectual support for relevant departments to allocate scientific research resources and promote the high-quality development of scientific research. [Method/process] The scientific research strength of scientific research institutions is characterized by point degree centrality, and the high? way mileage between the two institutions represents the geographical distance. On the basis of comprehensively consid? ering the factors of scientific research strength and geographical distance, the spatial gravity measurement model of sci? entific research cooperation institutions is constructed, based on the data of 410 winning projects of national scientific and technological progress awards from 2016 to 2020, Gephi software is used to calculate the point degree centrality of the cooperation institutions of the award-winning projects of the national science and technology progress award. At the same time, according to the institutional cooperation co- occurrence matrix, query the institutional highway mileage, calculate the spatial gravity between scientific research cooperation institutions, build the scientific research institution cooperation connection network, and reveal the institutional cooperation connection situation. [Result/conclusion] The tendency of cross regional scientific research cooperation among institutions is becoming stronger and stronger, but the obstacle of geographical distance to the strength of cooperation connection can’t be ignored. In order to promote the high-quality development of industry university research cooperation, the following suggestions are put forward: pro? mote the in-depth development of cross regional scientific research cooperation; design scientific and reasonable scien? tific research personnel flow mechanism; rational allocation of scientific research resources; firmly promote the transfor? mation of scientific.
