Since the Ice Silk Road (ISR) was put forward, its development prospect has become the focus of academic circles. To study the influence mechanism of 'fairness preference' on the trade cooperation of countries along the ISR, this paper constructs the trade cooperation network based on the bilateral trade data of countries along the ISR, establishes the theoretical model of network game based on Rabin model, and uses the simulation method to test the model. The results show that: (1) the sense of national cognitive fairness does have an impact on the trade cooperation of the ISR; (2) the 'eye for an eye, tooth for a tooth' strategy is not an advantage strategy in the trade cooperation of the ISR; (3) the most significant factor affecting the trade cooperation of countries along the ISR is the neighbor node in the trade network and the social public opinion pressure of cooperation in the network.

The Yangtze River Delta multi-port system (YMPS) receives increasing attention due to its relevance in world trade and excellent competitiveness in the container traffic market. To insight into the development pattern of YMPS, this paper proposes a method that combines the Hierarchical Clustering with compositional data (CoDa) exploratory tools (i.e., biplot and dendrogram) to explore the temporal and spatial evolution of the YMPS from 1992 to 2019. CoDa describes parts of some whole (i.e., frequency and percentage), conveying relative information in the ratios between its components. Container traffic share in a multi-port region is typical CoDa. Traditional statistical approaches to CoDa could lead to spurious correlations and erroneous conclusions. However, using suitable CoDa techniques, such as the centered log-ratio (clr) transformation, can effectively avoid these misinterpretations. The novel method can simultaneously find the temporal and spatial characteristics. The findings indicate that the development of the YMPS has gone through four stages and the evolution of the YMPS is characterized by a tendency towards a 'multi-core development' and faces a differentiated pattern of 'peripheral port challenges'. The analysis further improves the port system's evolutionary model and explains the underlying reason for the YMPS development. CoDa techniques also provide a new perspective for the temporal and spatial evolution of the transport discipline. [ABSTRACT FROM AUTHOR]
