技术创新网络多维邻近性演化研究

研究技术创新网络多维邻近性是否伴随创新网络生命周期不同发展阶段而呈现出不同演化特征，对创新网络内部伙伴选择、关系治理和创新绩效发展具有重要意义。基于IBM专利合作网络数据，运用Feature Selection方法，从地理邻近、社会邻近、技术邻近、组织邻近和制度邻近5个维度分析技术创新网络多维邻近性演化特征。结果表明：①生命周期视角下，在创新网络创生阶段，企业选择合作伙伴时主要考虑技术邻近性和组织邻近性，成长阶段主要考虑地理邻近性，成熟和衰退阶段主要考虑社会邻近性；②演化视角下，地理邻近性与技术邻近性曲线呈倒U型关系，地理邻近性在成长期达到最高点，技术邻近性在成熟期达到最高点；制度邻近性与组织邻近性呈U型关系，制度邻近性在成长期达到最低点，组织邻近性在成熟期达到最低点;社会邻近性则随着创新网络生命周期发展一直呈上升态势。

Multidimensional Proximities' Evolution of Technological Innovation Network

The study of the multidimensional proximities of technological innovation network shows different characteristics of evolution with the development of innovation network life cycle, has very important significance for partner selection, the relationship management and innovation performance in the innovation network. Based on the IBM patent cooperation network data, this paper analyzes the evolution of the multidimensional proximities of the technological innovation network by using the Feature Selection method in the five dimensions of geographical proximity, social proximity, technological proximity, organizational proximity and institutional proximity. The results show that:①In the life cycle perspective, mainly considering technological proximity and organizational proximity of partner selection in the innovation network creation stage, growth stage mainly consider geographical proximity, mature and decline stage mainly consider social proximity;②In the perspective of evolution, geographic proximity and technological proximity curve takes an inverted U type, geographic proximity reached the highest point in the growth stage and technology proximity reached the highest point in the mature stage; institutional proximity and organizational proximity curve takes an U type, institutional proximity reached the lowest point in the growth stage and organizational proximity reached the lowest point in the mature stage; social proximity has been the upward trend with the development of innovation network life cycle.
