Abstract: While promoting global economic and trade, ports have brought serious pollution to the global oceans and the atmosphere, and in the meantime a new technological and industrial revolutions are being pushed to their zenith. To this end, the port is facing green reform and smart reform. In the process of port reform, government support is undoubtedly very important, but the importance of government support and the evolutionary path in port reform still need us to explore. In addition, the strength of government support needs to be studied. Based on the dual perspectives of the government and the port, considering the cost of green smart port construction and the influence of government regulation, evolutionary game analysis is performed on the decision-making behavior of both sides of the government and the port, and the evolutionary path of green smart port construction is explored under the government regulation. The main driving factors of green smart port construction are also excavated, and the mutual restriction and coexistence relationship between the government and the port are depicted in the transformation of green smart port. Furthermore, Lotka Volterra model is used for reference to measure the diffusion trend of green smart port, the diffusion situation change of green smart port and ordinary port is depicted by simulating the government’s regulation and control, and the evolution demand of green smart port is reflected, and the limitations of green smart port under the non-government regulation and control are revealed, and the role of government regulation is confirmed in promoting the development of green smart port.
