Collecting and mining customer consumption data are crucial to assess customer value and predict customer consumption behaviors. This paper proposes a new procedure, based on an improved Random Forest Model by: adding a new indicator, joining the RFMS-based method to a K-means algorithm with the Entropy Weight Method applied in computing the customer value index, classifying customers to different categories, and then constructing a consumption forecasting model whose RMSE is the smallest in all kinds of data mining models. The results show that identifying customers by this improved RMF model and customer value index facilitates customer profiling, and forecasting customer consumption enables the development of more precise marketing strategies.

Drawing on the conservation of resources (COR) theory, the authors investigate whether and how social support impacts the emotional labor of live streamers through professional identity. They also explore the boundary conditions by focusing on the moderation effect of emotional intelligence. Based on a sample of 331 live streamers in the content industry, the results show that social support weakens (enhances) live streamers' surface acting (deep acting) by enhancing their professional identity. Emotional intelligence significantly moderates the professional identity-emotional labor relationship. In addition, they find that emotional intelligence strengthens the negative indirect effect of social support on surface acting through professional identity but weakens the positive indirect effect of social support and deep acting through professional identity. They also discuss theoretical contribution in emotional labor literature and practical implications for live commerce.

Along with the rapid development of digital information technology, e-government is of great potential because it is a new form of conducting public administration and a way of demonstrating governmental innovation. The literature suggests that foreign direct investment (FDI) is increasingly associated with the continuing development of e-government in China. Using the Annual Census of Industrial Enterprises and e-government scores of government portals, this study examines the effects of e-government on FDI and how government subsidies mediate relationships between e-government and FDI. Our results show that e-government positively affects FDI, and government subsidies have a positive effect on foreign enterprises' investment efficiency by playing a mediating role between e-government efficiency and FDI. The findings make both theoretical and practical implications related to the role, provision and acquisition of government subsidies; e-government systems and FDI; e-government scores and government efficiency; and firms maintaining focus on areas that are government priorities.
