The metaverse concept constructs a virtual world parallel to the real world. The social economic dynamics model establishes a systematic model for social economic dynamics simulation that integrates macroeconomy and microeconomy based on modeling mechanism of the new theory of value by analogy with Newtonian mechanics and the modeling approach of Agent-based computational economics. This article describes the SED model’s modeling mechanisms, modeling rules, and behavior equations. At the same time, this article introduces the methods, testing standards, and some typical cases about using the SED model to generate the economic digital twin systems. By doing so, we hope to demonstrate that the method of computer simulation experiment based on the SED model is a scientific empirical method, which has more advantages than the existing empirical research methods in economics. The SED model, which can be fully used to form an economic engine and construct a virtual economic system by digital twin method, can be integrated with the extant physical engine in the metaverse concept to build a virtual world consisting of physics, economy, culture, and politics that is close to and coexists with reality.

This study was designed to estimate the associations between self-efficacy and professional identity. A total of 1,051 freshmen nursing students from the Be Resilient to Nursing Career program were recruited from four universities between September and November 2020. A latent profile and moderated meditation analysis were performed. Four profiles of self-efficacy were identified and named as Lowest, Med-low, Med-high, and Highest. The mediating role of resilience and the moderating effect of role models were also identified. Therefore, self-efficacy, resilience, and role models may be three important factors to professional identity in FNSs and these relationships should be further validated in longitudinal or interventional studies.

This study integrates the resource dependence perspective and the stakeholder perspective to analyze local Chinese suppliers’ environment strategies in response to environmental requirements of different types of customers. With a sample of 1,215 local Chinese manufacturing suppliers, we examine the impact of export intensity and environmental requirements of multinational enterprises on local Chinese suppliers’ environment strategies. The results show that local Chinese suppliers with high levels of export intensity are more likely to adopt positive environment strategies to reduce environmental risks. In addition, local Chinese suppliers respond actively to environmental requirements of MNE customers but not to those of local customers. The linkage between MNE customers’ environmental requirements and local Chinese suppliers’ environment strategies remains significant, even after we control for the impact of export intensity. Implications of the findings conclude the article.
