This paper evaluates how purchases of wealth management products (WMPs) influence the performance of Chinese non-financial listed companies. Our main finding is that purchasing WMPs enhances firm performance, but the relationship shows an inverted U-shape: when WMP investment exceeds 62.57% of total assets, its positive effects diminish and ultimately harm performance. Heterogeneity analysis reveals that the performance gains are concentrated among non-state-owned enterprises (non-SOEs), while state-owned enterprises (SOEs) experience no significant benefits or even negative effects. Furthermore, the positive impact of WMPs is more pronounced in firms with higher leverage, abundant cash holdings or lower top-shareholder concentration.

In order to clarify the effect and mechanism of servitization level and digital transformation on the performance of listed sporting goods manufacturing enterprises in China, the index of the degree of digital transformation is constructed based on the data of 31 sporting goods manufacturing enterprises listed on Shanghai and Shenzhen A shares and the New OTC Market in China, taking the proportion of service business income in enterprise operating income as the index of servitization level, by analyzing the semantic expression of national policy related to digital economy and collecting "digital" category keywords in enterprise annual report with the help of crawler technology, then, the influence of servitization level and digital transformation on enterprise performance is discussed, and whether digital transformation plays a moderating effect between servitization and enterprise performance is tested. The results show that the servitization level suppresses the performance of listed sporting goods manufacturing enterprises, and there is a "Servitization Paradox" phenomenon. The degree of digital transformation has a positive U-shaped impact on enterprise performance, and at the same time, digital transformation has a weak positive moderating effect on servitization level and enterprise performance.
