It elaborated causes for these problems from the perspective of practice. Finally,it came up with recommendations for optimizing farmers' specialized cooperatives: building democratic decision making mechanism with coordination of cooperative members and able personnel,establishing supervision mechanism suitable for self demands,improving internal incentive mechanism,establishing talent introduction and cultivation mechanism in proper time,and strengthening internal member management of cooperatives.展开更多

Using the tail-event driven network(TENET)method, this study constructed a tail-risk spillover network(TRSN) of IEM and simulated the dynamic spillover tail-risk process through the cascading failure mechanism. The study found that renewable energy markets contributed more to systemic risk during the Paris Agreement and the COVID-19pandemic, while fossil energy markets played a larger role during the Russia-Ukraine conflict. This study identifies systemically important markets(SM) and critical tail-risk spillover paths as potential sources of systemic risk. The research confirms that cutting off the IEM risk spillover path can greatly reduce systemic risk and the influence of SM. This study offers insights into the management of systemic risk in IEM and provides policy recommendations to reduce the impact of shock events.展开更多

The paper defines the meaning of enterprise's post monetization management mechanism, which includes benefit, supply, demand, competition and incentive mechanism, and specifically explains the meaning and function of each subsystem in order to profoundly crystallize and grasp the importance of enterprise's post monetization management in the aspect of raising business management level.展开更多
