The Effect of Regulatory Adaptation and Cultural Training on Project Success: Mediating Role of Communication Efficiency in Yunnan Construction and Investment Holding Group

Introduction: This study explores the impact of transformational leadership on employee deviant innovation behaviour, focussing on the mediating roles of work missions and innovative self-efficacy while also examining the influence of regulatory adaptation, cultural training, and communication efficiency on project success. Objective: Leadership style is an important factor that influences employee behaviour. Based on trait elicitation theory, self-efficacy theory, and social information processing theory, this article selects transformational leadership and employee deviant innovation behaviour as research objects and selects work mission and innovative self-efficacy as mediating variables to explore the mechanism of transformational leadership on employee deviant innovation behaviour. Methods: SPSS was used to analyse 188 valid survey questionnaires; multiple linear regression models were used for analysis. Results: Regulatory adaptation and cultural training have a significant positive impact on project success, and they also have a significant positive impact on communication efficiency. In terms of the impact on project success, communication efficiency partially mediates the relationship between regulatory adaptation and project success, while communication efficiency partially mediates the relationship between cultural training and project success. Conclusion: This study provides practical insights for international project managers, emphasising the importance of regulatory adaptation, cultural training, and effective communication in achieving project success. This study highlights the critical role of transformational leadership in influencing employee deviant innovation behaviour, with work mission and innovative self-efficacy acting as key mediators. Additionally, regulatory adaptation and cultural training significantly enhance project success, with communication efficiency serving as a partial mediator in these relationships. These findings offer valuable insights for international project managers, emphasising the need for effective leadership, regulatory adaptation, cultural training, and strong communication to drive successful project outcomes.
