摘要
建立了基于联立方程的大连港吞吐量预测模型,利用二阶段最小二乘法和三阶段最小二乘法进行求解,从定量角度研究港城互动发展关系,实例证明此模型与实际情况符合较好,具有实际应用价值。
The paper establishes a model of Dalian port throughput forecast based on the simultaneous equations,which is solved by two-stage least squares and three-stage least squares,and the relation of this interactive development is researched quantitatively.The model agrees well with the practical situation,so it is of great practical value.
