并购企业关键研发者合作网络变化及影响因素研究

在区分关键研发者和一般研发人员基础上，利用24家涉及技术并购的高新技术企业1998-2017年全部发明和实用新型专利数据，从动态角度分两个步骤研究了技术并购对224名并购企业关键研发者合作网络的影响。社会网络与多元线性回归分析结果表明，随着技术并购发生，并购企业关键研发者度中心性、中间中心性、接近中心性整体均有所降低，结构洞有所增多；并购企业关键研发者与目标企业技术相似性、度中心性、中间中心性有显著负向关系，而与接近中心性关系不显著，与其结构洞有显著正向关系。结论从理论上拓展了技术并购对并购企业影响研究的视角，同时对并购企业管理者进行并购选择以及留住自身关键研发者并保持较高的创新绩效具有一定现实意义。

Research on the Change and Influencing Factors of Key Inventors Cooperation Network of Merger and Acquisition Enterprises

On the basis of distinguishing between key inventors and general inventors,based on the data of all inventions and utility model patents of 24 high tech enterprises that have undergone technological M&Afrom 1998 to 2017,the technological M&Awere studied in two steps from a dynamic perspective.The impact of a collaboration network of key inventors inM&A.Based on social network and multiple linear regression analysis,the results show that with the occurrence of technological M&A,the key inventors of the M&A enterprises have reduced degree centrality,betweenness centrality and closeness centrality,and the structural holes have increased.At the same time,the key inventors and target enterprises of technological M&A enterprises.The technical similarity has a significant negative relationship with its degree centrality and betweenness centrality,and its relationship with the closenesscentrality is not significant,but has a significant positive relationship with its structural holes.This research theoretically enriches the research perspective of the impact of technological M&A on M&A enterprises,and it has certain practical significance for M&A managers to choose M&A and retain their key inventors and maintain their high innovation performance.
