港口经济贡献的投入产出乘数模型

The Multiplier Model for Port Economic Contribution Analysis

准确估计港口对区域经济的贡献是明确其在港口城市中心地位的关键。针对港口的业务广泛性、公共产品性和区域独占性等特性,引入里昂惕夫逆矩阵和凯恩斯乘数,建立一种改进的港口经济贡献投入产出乘数模型。通过上海港的实证分析,表明了港口对区域经济具有乘数增长效应,验证了模型的可操作性和实用性。

Accurately measuring the economic contributions of a port to regional economy is the key to justify the core position of the port in a city.According to port business comprehensiveness,attribute of public goods and regional monopoly characteristics,an improved input-output multiplier model for port economic contribution analysis is presented by introducing Leontief inverse matrix and Keynesian Multiplier.Through a case study of Shanghai port,the paper demonstrates that port growth can lead to multiply growth of regional economy.The model is suitable for analyzing contributions of port to regional economy.
