The optimization of foreign trade and economic growth in the field of port planning are the core of foreign trade planning and management. There is a significant positive correlation between foreign trade and economic growth in the field of port planning. In order to reduce the cost of port foreign trade, at the same time, an equilibrium quality model between foreign trade and economic growth in port planning based on closeness decision-making is proposed to improve the foreign trade in the field of enterprise port planning. The constraint objective function of foreign trade and economic growth in the field of port planning is established from the perspective of balanced quality, and the parametric model affecting the management of foreign trade and economic growth in the field of port planning is analyzed. According to the contribution weight of economic growth parameter and risk level, the optimal decision-making equilibrium quality model of port planning is designed, and the decision-making model of closeness degree is established based on the distribution of foreign trade capital structure and the index of economic growth as the core explanatory variables. To realize the self-adaptive optimal decision-making equilibrium quality control between foreign trade and regional development of port economy in the field of port planning. The statistical analysis of cost-benefit is carried out by using the Hausman test rule. The empirical results show that the model can reduce the cost of port foreign trade and improve the core competitiveness of port regional economy, and the model can be used for foreign trade planning and management, and the management benefits are optimized.
