RISK TRANSMISSION AND CONTROL OF PORT-HINTERLAND SERVICE NETWORK: FROM THE PERSPECTIVE OF PREVENTIVE INVESTMENT AND GOVERNMENT SUBSIDIES

The increase in risk prevention investments the port-hinterland service network (PHSN) effectively enhances network’s ability to resist risks and improve sustainability stability of ocean transportation. Based on construction PHSN investment utility model, equilibrium strategy, related characteristics each participant complementary networks complete are analyzed. Similarly, subsidy policy government under maximization whole is studied. We further propose new types strategies based key nodes groups given resources available efficiency constraints imposed, while also validating advantages this method a case analysis. results indicate that (1) closely Katz-Bonacich centrality, interaction intensity, cost unit competition intensity; (2) an undifferentiated strategy cannot effectiveness network; (3) improves efficiency; (4) superior nodes. Accordingly, study provide reference for participants managers when making decisions.
