【摘要】 数字技术不仅影响企业创新内容，也影响企业创新模式。作为企业整合网络生态资源的重要方式，合作创新成为数字经济时代企业的重要创新模式。本文基于知识基础观理论，利用2007—2021年中国上市公司41.15万项合作申请的专利数据发现，数字技术应用显著提升了企业的合作创新水平，超级明星发明家会增强数字技术应用对企业合作创新水平提升的促进作用。作用机制方面，数字技术应用提高了企业对外部知识的搜寻能力和整合能力，从而促进企业合作创新。拓展性分析发现，企业将数字技术应用于生产流程中将更有利于提升合作创新水平；进一步区分企业合作创新的对象发现，数字技术应用对企业间以及企业与高校间的合作创新水平提升具有更强的促进作用。本文结论为我国企业抓住数字技术所带来的战略机遇，在合作创新中提升创新绩效提供了启发与参考。更多还原

【Abstract】 The essence of innovation is the mutual integration and comprehensive utilization of knowledge in different fields.However,the division of labor in the modern large market means that companies usually only have professional knowledge in a specific technical field.This is both a source of competitive advantage for companies and an obstacle to their further growth and innovation.With the rapid development of digital technology,it has had a disruptive impact on the technological level of companies.Companies need more abundant knowledge resources as a supplement in their innovation activities and actively communicate with the outside world to capture new innovation opportunities.Collaborative innovation has become a rational innovation model choice for firms.Collaborative innovation emphasizes that enterprises can improve their own innovation capabilities by supplementing external innovation resources.That is,the resources required for innovation are no longer limited to the ideas and knowledge within the enterprise itself,but can also come from universities,research institutions and even competitors.Although the research on the influencing factors of enterprise collaborative innovation has been very rich,the research on the influence of digital technology on enterprise collaborative innovation has just started. There are two characteristics in the current research on digital technology and corporate collaborative innovation:first,it is mainly based on the perspective of spatial and temporal distance,and rarely explores the impact mechanism of digital technology on corporate collaborative innovation from the perspective of knowledge; second,it only focuses on the overall effect of digital technology on corporate collaborative innovation,but does not distinguish the structural characteristics of corporate digital technology applications and the types of cooperation partners.Based on the theory of knowledge-based view,this paper makes use of the data of 426,500 cooperative patent applications of Chinese listed enterprises from 2007 to 2021,and finds that the application of digital technology significantly improves the cooperative innovation performance of enterprises. In terms of the underlying mechanisms,the adoption of digital technology improves firms’ ability to search for and integrate external knowledge,thereby facilitating collaborative innovation. Additionally,the presence of superstar inventors positively moderates the relationship between firms’ digital technology adoption and collaborative innovation.This research makes three main theoretical contributions to the literature:First,it enriches the literature on the impact of digital technology on corporate collaborative innovation.This paper innovatively divides the depth of digital technology application by enterprises into four links:“digital production”,“digital management”,“digital products” and “digital marketing”,and deeply analyzes the specific business links through which digital technology affects corporate collaborative innovation.In addition,this paper also divides the objects of corporate collaborative innovation into four types:“enterpriseenterprise”,“enterprise-university”,“enterprise-research institute” and “enterprise-other”,so as to deeply examine the impact of digital technology application on different types of corporate collaborative innovation. Second,it expands the relevant research on knowledge-based theory.The knowledge-based theory believes that knowledge is the key resource that determines the innovation performance of enterprises. Especially in the digital economy era,digital technology has effectively reduced the cost of enterprises to obtain information and knowledge from the outside. This paper reveals the internal mechanism of digital technology affecting enterprise cooperative innovation from the two perspectives of knowledge search and knowledge integration,and expands the application boundary of the knowledge-based theory. Third,it supplements the research on the impact of human capital on corporate innovation. Superstar inventors are the most important human capital in the enterprise innovation process.Existing literature has found that inventors have an impact on the quantity and quality of patents of enterprises,but the role of inventors as a carrier of internal knowledge accumulation on enterprise cooperative innovation has been ignored.This paper finds that superstar inventors have a significant positive moderating effect on the application of digital technology to improve the level of enterprise cooperative innovation,which provides empirical evidence for enterprises to vigorously train and accumulate superstar inventors.更多还原
