Abstract: Based on the perspective of multiple institutional logic and enterprise heterogeneity, an analytical framework is constructed to explore the formation mechanism of enterprise technology innovation strategies, with GAC Group and BYD as research objects. Research has found that (1) institutional complexity and corporate heterogeneity lead to heterogeneity in the technological innovation strategies of new energy vehicle enterprises, resulting in differences in the effectiveness of technological innovation strategies. (2) Under similar complex environments, heterogeneity of enterprises leads to differences in response willingness, thereby affecting the innovation of enterprise technology innovation strategies. (3) In the long run, the technological innovation strategy of new energy vehicle enterprises has achieved similar results, and the technological innovation strategy of heterogeneous enterprises has achieved similar results. The research conclusion of this article helps to deepen the understanding of the mechanism of technological innovation strategy for new energy vehicle enterprises in China and provides beneficial practical inspiration for the government and enterprises to accelerate the advancement of new energy vehicle technology breakthroughs.

摘要： 复杂技术的追赶已经成为我国技术追赶的关键。多重制度逻辑视角的外部环境的动态性、复杂性与交互性等特征，是解释后发企业复杂技术创新战略形成机理的重要理论基础。本研究通过广汽集团和比亚迪这两家新能源汽车行业的后发企业，探究后发企业在初始追赶阶段、追赶加速阶段、赶超追赶阶段，多重制度逻辑与企业资源能力的匹配影响企业技术创新战略的机理：（1）不同阶段中，面对多重制度逻辑的不同要求，企业根据自身资源能力选择性耦合，广汽集团形成跟随-并跑-继续并跑的技术追赶战略，比亚迪形成抢跑-继续抢跑-领跑的技术追赶战略。（2）多重制度逻辑与后发企业技术追赶战略共演，对多重制度逻辑的选择性耦合形成技术创新战略，并进一步推动多重制度逻辑演化与企业资源能力提升。本研究的结论有助于深化对我国后发企业复杂技术追赶战略的机理认知，为政府和企业加快推进复杂技术突破带来有益的实践启示。
