For the green emission reduction and price decision issue between two adjacent ports(one green port and one ordinary port)in a region,the Stackelberg game theory is used to establish the decision-making models under the green port as the market leader mode(GL mode),the ordinary port as the market leader mode(OL mode)and no market leader mode(NL mode),respectively,and the influence of various market competition environments on green emission reduction and price decision is investigated.The results indicate that the service price of the green port is positively correlated with the emission reduction rate,while the service price of the ordinary port is negatively correlated with it.Various market competition environments have different effects on the emission reduction rate of ports:the green emission reduction rate under the GL mode is the highest,followed by the NL mode,and the green emission reduction rate under the OL mode is the lowest.The emission reduction rate is negatively correlated with the difficulty coefficient of the green technology innovation,and positively correlated with the price subsidy coefficient of government for the green port.The government price subsidy for the green port can effectively share the investment risk of the green technology innovation in the early stage of green emission reduction.When the green preference degree of shipping enterprises is higher enough,the emission reduction rate is consistent under every market-dominated mode.The government needs to advocate the green consumption behaviors when subsidizing green ports,so as to enable more market players to participate in the green consumption.
