公司之間與公司內部的合作網路：網路結構對於公司創新的影響

Abstract

本研究利用公司策略聯盟的合作網路以及發明者專利共同發明的合作網路來同時建立企業內部與外部的網路結構，並針對兩種網路結構來探討其網路大小、網路有效性兩個網路特性對於企業創新的影響為何，以及企業內部網路的網路大小和技術多樣性如何干擾企業外部網路，以分析企業內部網路和外部網路在企業專利創新上的角色為何。本研究收集資訊通訊科技產業與製藥產業的次級資料，採取社群網路分析的方式，並藉由負二項回歸法來驗證其假設。研究結果顯示企業內部網路與企業外部網路的網路大小與網路有效性，對於企業的創新皆具有正向的影響力，且企業內部的網路大小與技術多樣性，也會有效干擾企業外部網路大小、網路有效性與創新之間的關係。

This study constructs inter-firm collaboration network by strategic alliances and intra-firm collaboration network by patent co-invention simultaneously and investigates the impact of network size and network efficiency in these two networks on firm innovation. And we also examine how intra-firm network size and technological diversity influence the relationship between inter-firm network structure and innovation to explain the role of these variables on firm innovation. The study employs the secondary data analysis and social network analysis in information and communication technology and pharmaceutical industry, and the negative binomial regression is used to testing our hypotheses. The results indicate that both network size and network efficiency in inter-firm network and intra-firm network contribute to firm innovation. And the effects of inter-firm network structure on innovation are moderated by intra-firm network size and technological diversity.
