This study systematically summarizes the digital economy's impact on corporate innovation based on four influencing mechanisms, namely enterprise digitalization levels, research and development (R&D) efficiency, R&D cooperation, and human capital. It empirically analyzes this impact from the perspectives of effects, mechanisms, and heterogeneity by matching the Chinese provincial-level digital economy evaluation index with the A-share listed companies' patent data. The results show that if the digital economy-level increases by 1% in a province, enterprises' number of invention patent applications will increase by about 3.70 on average. Additionally, its development has significantly improved the digitalization level of enterprises and promoted their R&D efficiency, which in turn fosters enterprise innovation. Finally, the digital economy's impact on enterprise innovation exhibits heterogeneity, showing a more significant innovation effect on low marketization, high industry technology intensity, and private enterprises. Overall, the findings have important theoretical and policy implications for understanding how the digital economy is deeply integrated into the real economy, thereby promoting enterprise innovation.

To systematically study how trendy toy brands trigger and promote consumers' impulsive purchasing behavior, this research takes the phenomenal IP—LABUBU as a case, adopts a cross-platform and multi-source qualitative data collection method, and deeply analyzes consumers' psychological motivations and behavioral performances under multiple dimensions such as emotion, social interaction, and collection. By sorting out user comments, graphic sharing, and media reports on platforms including Xiaohongshu, Zhihu, Douyin, Weibo, and news websites, combined with existing literature theories, this study constructs a comprehensive analytical framework. The research finds that the influencing mechanisms of impulsive consumption induced by trendy toy brands can be mainly summarized into three categories: Design Preference and Emotional Value; Playability and Social Attributes; Collectibility and Global Popularity. Each category of mechanism is supported by specific cases and real consumer feedback. This study not only theoretically reveals the formation path of irrational decision-making in trendy toy consumption behavior and makes up for the lack of empirical research in this field, but also practically provides consumers with reference dimensions to identify and reflect on their own impulsive consumption tendencies, and offers enlightenment for brand owners' marketing strategies and market management. Future research can further extend to the perspectives of corporate marketing strategies and regulatory policies to form a more comprehensive understanding.
