摘要：The development of port logistics and regional economy presents a linkage relationship. This paper resorted to the commonly used econometric software, namely Eviews, to undergo some empirical analysis. One of its applications, known as the Granger Causality Test, is to provide evidence about the direction of causality in economic relationships. The competitiveness of port city logistics evaluation index system was set up based on the Diamond Model, which took cargo throughput, total freight, length of transportation routes and total retail sales of social consumer goods into consideration. It set on the example of 22 cities in the Yangtze River Delta of China. Based on the accumulated statistics, it went through the methods of Unit Root Test, Co-integration Test and Granger Causality Test, and eventually proved the linkage relationship between port logistics and economy of the cities. At last, the results proved that the Eviews is applicable and effective in causality analysis between variables of port logistics and regional economy.
