In order to explore the enabling mechanism, as well as the mechanism of government classification regulation on smart platforms and pharmaceutical enterprises' CSR strategies, a tripartite evolutionary game model for the government, smart platforms, and pharmaceutical enterprise is constructed. Through the analysis of the critical condition, stability and evolution path of the evolution of the tripartite strategy, it reveals the action mechanism of each factor and the evolution law of the tripartite game, and analyzes the influence of key factors such as the equilibrium state of system evolution and regulatory policies based on Anylogic simulation. The research shows that: Government classification regulations significantly affect the CSR performance decision and intelligent supply chain construction of pharmaceutical enterprises and intelligent platform, and the regulatory effect is affected by the sensitivity of the policies of both parties; Increased intelligence can strengthen the risk flexibility and autonomy of intelligent platform and pharmaceutical enterprises, but there are limitations in the space and time for pharmaceutical enterprises to implement strategies; When the reward coefficient is moderate, the evolution speed of smart platforms and pharmaceutical enterprise is significantly positively correlated with the reward coefficient. Based on this, it proposes measures to improve the efficiency of government CSR governance and solve the dilemma of CSR implementation in the pharmaceutical industry.

In order to explore the impact of network structure and knowledge base on enterprise innovation performance, the cooperative innovation network of industry-university-research institute is constructed from the perspective of social network, and the negative binomial regression model is used for empirical analysis. The results show that the industry-university-research innovation network centrality has a significant positive impact on enterprise innovation performance, network structure hole does not show a significant inverted U-shaped relationship with enterprise innovation performance, knowledge base has a significant positive impact on enterprise innovation performance, and the interaction between knowledge base and network centrality has a significant negative impact on enterprise innovation performance, the interaction between knowledge base and structure hole has a positive effect on enterprise innovation performance, but it is not significant.

Cooperative behavior is widespread, and how to promote the emergence of cooperative behavior has been a hot issue of systems science. Combining the traditional complex network model with the game theory model, this paper proposes a grouping selection rule for individual interaction and investigates the joint influence of the parameter dividing the groups, the individual's memory length, and the network clustering coefficient on cooperative behavior. Through simulation experiments, it is found that the grouping selection can effectively promote not only the emergence of cooperative behaviors in adjustable clustering networks, but also the individuals' cooperation in lattice and small-world networks, indicating that the rule has certain universality and repeatability. It provides a new approach to improve the overall level of cooperation in large-scale groups, enabling us to gain a deeper understanding of real-world cooperation phenomena and opening up a new avenue for exploring the reasons behind individuals' cooperative behavior.

To study the controllability of a class of directed signed multi-agent systems based on directed paths, the Laplacian matrix and graph theory are used to analyze. Firstly, it is proved that adding or removing a specific class of edges in the network does not change the system's controllability. Secondly, the controllability of the directed paths is studied, and then we check the system's controllability after adding reverse or forward edges in the directed paths. The results show that increasing the reverse edges in directed paths has no influences on its original controllability, However, the system's controllability needs to be analyzed according to the specific situations while increasing the forward ones by taking advantage of the almost equitable partitons. Finally, combined with the results above, a method of constructing directed complex network topologies is given.

Novel coronavirus is a new type of virus, and its transmission characteristics are different from previous virus. Infected people not only have an incubation period, but also a large number of asymptomatic infections. Based on the classic model SEIR, this study redefines the latent state as close contact state, introduces an asymptomatic state of infection, and the influence of time on the state transition parameters in the model is considered, proposed a new transmission model which includes five types of states: susceptible state, close contact state, asymptomatic infection state, infected state, and removed state. The model uses the actual epidemic data of Hubei Province to conduct experiments, and uses RMSE and MAPE as evaluation indicators to compare the experimental results. The results show that the fitting accuracy of the SCUIR model has been significantly improved. Compared with the traditional model, the fitting error is reduced by 8.3%~47.6%, and hidden data that is difficult to count in the epidemic can be calculated, which further characterizes the mechanism of epidemic transmission.

The subsidy of innovation voucher policy for low-carbon technological innovation of manufacturing enterprises has the feature of post-subsidy. This paper constructs a game model of government regulation and manufacturing enterprises to carry out low-carbon technology innovation under the policy of innovative vouchers subsidy. The results show that, first, when government supervision is more than a certain threshold, it can offset the insufficient of innovation motivation in the manufacturing enterprises. Second, government should choose different guidance method according to the innovation risk level: in high-risk situations, the impact of increasing punishment on the evolution speed of enterprises is more significant, thus, the government should promote the evolution of manufacturing enterprises to low-carbon technology innovation strategies through punishment mechanisms; in low-risk situations, the effect of punishment on the evolution speed of manufacturing enterprises tends to be steady, and the increase of subsidy coefficient can speed up their evolution. At this time, the government should take the subsidy mechanism as the mainstay and the penalty mechanism as the supplement to guide manufacturing enterprises to carry out low-carbon technological innovation.

In order to study the relevant policies under the evolution of scrap copper trade, this paper analyzes the evolution characteristics of scrap copper trade based on complex network theory, and analyzes its correlation with coal index, global copper reserves, global copper output and copper futures price. The results show that there is a positive and negative correlation between coal index, copper futures price and network statistical characteristics in the same period or the previous period. Global copper production, reserves and network statistical characteristics show positive and negative correlation in the same period. Based on the above results, this paper puts forward the corresponding response strategies from the aspects of import structure, energy price adjustment and import policy.
