Abstract: Abstract: the purpose of this paper is to research the driving factors of technical cooperation and to explore its influence factors at the national level. Assume the influence of technological proximity on the existence of international technical cooperation, using proximity analysis method, considering the moderator variables of social proximity and geographic distance, with patent cooperation data between the belt and road countries, using social network analysis of quadratic assignment problem (QAP) method. Research has shown that technological proximity with the international technology cooperation between the belt and road countries is inverted u-shaped relationship, social proximity and geographic distance adjust the impact. Result means too high or too low technology combination of homogeneity was unfavorable to increase technical cooperation performance, at the same time national geographic distance slow effect of technical proximity to the international technology cooperation. This study provides reference for the planning of international technical cooperation.

摘要： 摘要：本文旨在研究技术合作驱动原因，并在探索其在国家层面上的影响因素。提出技术接近性对国际技术合作的影响假设，运用接近性分析方法，考虑社会接近性和地理距离等其他因素，以“一带一路”合作专利数据为研究对象，运用社会网络分析中的二次指派程序（QAP）方法。研究表明：国家之间技术接近性与技术合作呈倒U型关系，社会接近性与地理距离对合作具有调节作用。意味着过高或过低的技术领域组合的同质化都不利于提高技术合作绩效，同时国家间地理距离减缓了技术接近性对国际技术合作效应的影响。本研究对国际技术合作开展与筹划提供参考。
