Abstract: Chinese economy is stepping forward from the stage of high-speed growth to the stage of high-quality development, and green development has become the indispensable requirement of high-quality development. With the proposal of the national goal of ‘carbon neutrality’ and ‘emission peak’, the green development of enterprises is facing unprecedented opportunities. Green supply chain has become an important source of competitive advantage. How to promote the green development of supply chain has become an important issue to be solved by industry and academia. Due to the great uncertainty of market demand, supply chain members show risk aversion preference, which affects the level of green technology investment and pricing decisions. In the current research about dual channel supply chain，however，there are few studies on this phenomenon this study effectively makes up for the lack of this research.
