R&D Alliances and Firm Performance: The Impact of Technological Diversity and Alliance Organization on Innovation
研究了合作伙伴技术多样性和联盟组织形式对企业创新绩效的影响，发现中等技术多样性最有利于创新，且层级组织（如合资企业）在高技术多样性时效果更佳。
In this paper, I examine the impact of partner technological diversity and alliance organizational form on firm innovative performance. Using a sample of 463 R&D alliances in the telecommunications equipment industry, I find that alliances contribute far more to firm innovation when technological diversity is moderate, rather than low or high. Although this relationship holds irrespective of alliance organization, I find that hierarchical organization, such as an equity joint venture, improves firm benefits from alliances with high levels of technological diversity. Thus, alliance organizational form likely influences partner ability and incentives to share information, which affects performance.
