Abstract： ［Purpose/Significance］In order to promote the compliance management of trading places in the era of digital intelligence and create a safe and credible circulation environment, it is particularly important to design the system around the security obligations of operators of data trading platforms.［Method/Process］As a new business place, the data trading platform’s operators’ security obligations can be justified by the theories of profit reward, control power and trust protection.［Result/Conclusion］From traditional business premises, e-commerce platform to data trading platform, due to the differences in risk control power of operators and other factors, the three show a type sequence of increasing security obligations and civil liability levels. The security obligations of data trading platform operators should include pre-, mid-and post-transaction obligations such as qualification examination, providing a safe and reliable trading environment and recording trading traces. When other infringers are involved, the determination of the liability form of the data trading platform should be standardized and continued through part of joint liability, so as to reasonably determine the civil liability of the operators of the data trading platform.

Abstract： In the era of digital economy, digital transformation has emerged as a critical factor in driving high-quality enterprise development. However, many companies encounter internal challenges, such as a lack of employee support and passive cooperation during the process of digital transformation. Current research on enterprise digital transformation primarily concentrates on the macro-strategic level, while the impact of digital transformation on employees has not been sufficiently explored. Therefore, our study takes a micro-level perspective within the organization and employs the Process Theories of Occupational Stress. We view digital transformation as a “stressor” and aim to investigate the different responses of employees to it and the underlying mechanisms. First, we investigate the “stressor” by utilizing Grounded Theory to uncover how employees perceive and identify stressors during digital transformation. Second, we explore the “stress outcome” by examining the impact of digital transformation on employees’ work performance and its dynamic changes over time based on the Transition Processes framework. Third, we investigate the “stress experience” from both cognitive and emotional perspectives. We explore the mechanisms, boundary conditions, and subsequent consequences of employees’ different responses (support or resistance) to digital transformation. This paper not only expands the scope and content of research in the field of human resource management, but also provides practical insights for companies to systematically drive digital transformation and improve employee support throughout the process.

Abstract： With a further deepening of globalization, an increasing number of business leaders now have multicultural experiences. Multicultural experiences refer to an individual's direct or indirect experiences of encountering or interacting with elements of foreign cultures and/or foreigners. In recent years, as the business practice is placing higher emphasis on the multicultural experiences of leaders, researchers are beginning to investigate the role of leaders' multicultural experiences in organizational management. Based on the current research findings and latest research progress, this study aims to explore the impact of multicultural experiences on leaders' capabilities and development from two levels—leader development and leadership development. First, we investigate the impact of multicultural experiences on leader development (including the individual-level, relational-level and collective-level capabilities) and the underlying mechanisms. In Research Module 1, based on the theory of integrative complexity, we explore the effects of leaders' multicultural experiences on their capabilities at the individual level (including innovation, problem-solving, and self-regulation capabilities) and relational level (interpersonal communication), the mediating role of integrative complexity, and the moderating role of leaders' engagement in multicultural experiences and intercultural distance. In Research Module 2, we investigate the effects of leaders' multicultural experiences on their collective-level capability (ethical decision-making) and the underlying mechanisms. We also discuss the differentiated effects of the breadth and depth of multicultural experiences on leaders' ethical decision-making. Second, we investigate the effects of multicultural experiences on leadership development (including leadership emergence, leadership selection, and leadership effectiveness) and the underlying mechanisms. To be more specific, in Research Module 3, we investigate the impact of different types of multicultural experiences on leadership emergence, leadership selection, and leadership effectiveness, the mediating role of perceived resource availability, in-group similarity and interpersonal effectiveness, as well as the moderating role of leader-team fit. The theoretical contributions of this paper are mainly threefold. First, our study explores the relationship between multicultural experiences and leadership against the backdrop of globalization and expands the research scope of multicultural experiences into organizational management settings. Second, our study introduces multicultural experiences into leadership research and explores the impact of global changes on leadership, providing new context and insights into leadership research. Third, the study takes the perspective of integrative complexity theory to reveal the mechanisms behind the effects of multicultural experiences on leaders' capabilities development through the lens of individual cognition and experiential learning. Moreover, the study provides implications for global management and international talent fostering practices.
