Research on the correlation of port logistics and regional economic growth base on gray relational analysis method

摘要

Costal Port, as modern transport hub and logistics nodes linking airlines, railways, highways, andother transport means, plays an important role in driving regional economic growth, while theregional growth in Port inter-lands offer substantial support and guarantee for the port logistics.The correlation between port logistics and regional economic growth, therefore, may serve theentry point of research on the sustainable development of both Shenzhen and its port, given thepositive interplay of the port logistics with regional economy, will gain a better strategic positionin the Belt-and-Road Initiative and the Guangdong-Hong Kong-Macao Greater Bay Area. Graycorrelation analysis and decision tree algorithm are both employed in the light of the status quoof ShenzhenPort to closely examine relevancy between the port logistics and regional economicdevelopment. The relevancy among gross industrial output value, total investment in fixed assetsand gross import and export value reads 0.69:0.682:0.643, respectively, in contrast to the leastrelevancy of the construction industry; the gross industrial output value as well import and exportvalue, according to the decision tree algorithms, exert decisive influences on the port logistics.
