With the vigorous development of the global scientific and technological revolution, the technological innovation in the form of team is becoming an important core force of economic development. Due to the uncertainty and high risk in the process of innovation, innovation failure becomes more common. The economic, social, physiological and psychological problems brought about by the failure have hit the enthusiasm and confidence of innovators, making the members of the innovation team in a slump. However, the existing research also realizes the value of innovation failure, and believes that previous failure experience is conducive to the occurrence of subsequent innovation behavior, and can provide opportunities for innovators to reflect and self-study. As a high-level learning method, failure recovery plays a key role in the subsequent restart of innovation. However, how does the innovation failure come out of the failure to achieve the state of recovery, what is the process of recovery, and whether innovation failure recovery is an effective path linking technological innovation failure to continuous innovation behavior? In addition, the emotional role of the psychological level can not be ignored. What role does the innovation passion of team members play in the recovery of failure? These are the urgent problems faced by team innovation members. However, the related research is slightly weak. This paper is based on these weaknesses for the technical innovation team of science and engineering theory and practice guidance.

This paper mainly focuses on the following aspects:(1) this paper systematically reviews the current research status; (2) from the characterization of technological innovation failure, it divides technological innovation failure into failure frequency and failure Chengdu; the recovery of innovation failure is divided into problem response and emotional response; the team innovation passion is divided into collective identity and common positive emotion, and team technology innovation failure is constructed the relationship model of innovation failure recovery and continuous innovation behavior and puts forward the corresponding research hypotheses; and (3) this paper conducts empirical analysis on 346 valid samples collected from 62 teams, verifies and discusses the proposed hypothesis and model, and obtains the corresponding theoretical and practical enlightenment.

It is found that there is an inverted U-shaped relationship between the number and degree of technological innovation failure and continuous innovation behavior. Innovation failure recovery can be divided into two dimensions: problem coping and emotional coping, which plays a partial mediating role between technological innovation failure and continuous innovation behavior. Technological innovation failure affects the recovery of innovation failure through the inverted U-shaped curve effect, and then affects the continuous innovation behavior. The effect of failure recovery is directly related to whether the failure can restart innovation and achieve innovation success. Team innovation passion moderates the relationship between innovation failure recovery and continuous innovation behavior. 

Based on the above conclusions, this paper integrates the process framework of "technological innovation failure, innovation failure recovery, continuous innovation behavior". This research puts forward the countermeasures and suggestions from four aspects: innovation team formation and management, innovation failure management, team emotion management, and policy support, in order to provide theoretical and practical guidance for the failure of the innovation team. This paper enriches the theory of failure recovery, makes up for the lack of theoretical research on innovation passion, and broadens the relevant theoretical research on the influence of emotion on innovation process.
