This paper constructs a dual-channel value chain composed of one altruistic manufacturer and one altruistic retailer, where the manufacturer makes green innovation input for green products and sells its green products to its customers through both the direct channel and the traditional channel, the retailer provides channel service for customers and sells green products through the traditional channel. We consider two scenarios in which the manufacturer and the retailer make decentralized and centralized decisions, respectively. We develop two dynamic game models for the two scenarios and analyze the dynamic behaviors of the two dynamic game models using bifurcation diagram, LLE (largest Lyapunov exponent) and attraction of basin, etc. We find that the stability region in decentralized decision model is greater than that of centralized decision, and narrow with increase of service value, green innovation input. In the decentralized decision model, the stability of the system decreases with the altruistic behavior increasing. With the price adjustment speed increasing, the dual-channel green value chain system enters into chaotic state through flip bifurcation or N-S bifurcation. In the stable state, the manufacturer and the retailer can obtain the maximum utility with the appropriate value of green innovation input. In the chaotic state, the utilities of the manufacturer and retailer are greatly affected and significantly reduced. This study will provide good guidance for sustainable development decision-making of dual-channel green value chain.

This paper summarizes the relevant literature through the content analysis method and combines expert advice. The company built a four-level indicator including traffic knowledge and skills, and 13 pilot-level traffic literacy evaluation indicators system including traffic rules and mechanical common sense. The Analytic Hierarchy Process (AHP) analysis method is used to determine the weight of each indicator of urban driver traffic literacy evaluation, and conduct pilot survey and evaluation of motor vehicle drivers in Zhengzhou. The results show that the evaluation value of motor vehicle driver traffic literacy in Zhengzhou is 72.07, including a traffic knowledge score of 77.09, traffic awareness score of 73.95, traffic skill score of 78.12, and traffic behavior score of up to 84.3. It shows that the respondents have relatively more active and responsible traffic behaviors and have a certain degree of understanding of traffic skills and traffic knowledge. However, they are relatively low in traffic awareness.
