Abstract:Based on the theory of individual-team fit and social exchange differentiation, this paper constructs four team variables such as differentiated employee mindfulness(DM), differentiated trust in leader(DT), differentiated harmonious passion and differentiated obsessive passion,and then collects leader-subordinate matching questionnaire data of 272 teams. By using polynomial regression and response surface analysis, this study finds that the fitting of DM and DT is an important factor that leads to the differentiation of employee dualistic work passion. It can have a complicated impact on team innovation performance through differentiated dualistic work passion. In particular: (1) the congruence between DM and DT is negatively related to team innovation performance. (2) In the case of the congruence of DM and DT, the team innovation performance is higher when "low DM-low DT" than "high DM-high DT"; Compared with "low DM-low DT", "high DM-high DT" leads to higher differentiated harmonious passion and differentiated obsessive passion. (3) In the case of mismatch between DM and DT, team innovation performance is higher when "high DM-low DT" than "low DM- high DT"; Compared with "high DM- low DT", both the differentiated harmonious passion and differentiated obsessive passion when "low DM- high MT" are lower. (4) Both differentiated harmonious passion and differentiated obsessive passion can mediate the interaction of DM and DT on team innovation. Therefore, in order to stimulate the passion of employees and enhance team innovation, managers should pay more attention to the differentiation within the team, apply well-established monitoring systems, employee mindfulness training, employee motivation and other methods in practice, and make management decisions more scientifically and reasonably.
