联盟创新网络中的局部集聚性是企业间“拉帮结派”的重要体现,这一结构对企业创新的影响已引起人们的关注。文章基于2000-2013年中国高端装备制造产业的企业间联盟数据,通过联盟关系构建创新网络,运用负二项回归模型分析派系和核心度对企业创新的影响进行分析。研究表明,联盟创新网络中派系数越多,嵌入企业的创新能力越强,且此影响具有明显的滞后性;企业的核心度对企业创新能力的影响呈现倒U形关系,即当核心度小于某一特定值时,企业的创新能力随着核心度的增加而增强;当核心度大于这一特定值时,企业的创新能力随着核心度的增加而下降。简言之,“拉帮结派”能够促进企业创新,但企业嵌入派系时要考虑适度规模的企业间关系以使自身创新收益的最大化。研究结论可为企业嵌入网络派系,相关政府部门制定联盟政策提供依据。
Local agglomeration in the network of alliances is an important manifestation of inter-firm “pull-gang”. The impact of this structure on enterprise innovation has drawn people’s attention. Based on the data of alliance between enterprises in China’s high-end equipment manufacturing industry from 2000 to 2013, the article builds an innovation network through alliances and analyzes the influence of factionalism and core degree on the innovation of enterprises by using negative binomial regression model. The research shows that the more coefficients in the innovation network, the stronger the innovation capability of embedded enterprises, and the obvious lagging effect. The influence of the enterprise’s core on the innovation ability of enterprises presents an inverse U-shaped relationship, that is, when the core is less than At a certain value, the innovation ability of enterprises increases with the increase of the core; when the core is greater than this specific value, the innovation ability of enterprises decreases with the increase of the core. In short, “pull-gang” can promote business innovation, but companies should consider the modest scale inter-firm relationship in order to maximize their innovation benefits when embedding the faction. The conclusion of the study can provide the basis for enterprises to embed network factions and relevant government departments to formulate alliance policies.
