Research On The Interactive Relationship Between Port Logistics Industry Cluster And Regional Economic Growth In Yangtze River Economic Zone

As an important channel for connecting regional logistics,capital flow,and information flow,the port changes from a single transport transfer station to a modern logistics service center.Benefited from the scale effect,knowledge spillovers,and brand effects,etc.Port logistics industry clusters have been gradually formed,which has created a new growth point for the regional economy.In September 2014,the State Council issued the Guiding Opinions on Relying on the Golden Waterway to Promote the Development of the Yangtze River Economic Zone(hereinafter referred to as “Opinions”),pointing out that it is necessary to upgrade the functions of the golden waterway of the Yangtze River and optimize the layout of the port functions.The issuance of the "Opinions" shows that improving the functions of the port of the Yangtze River Economic Zone has become an important task at the national level.In order to take advantage of the advantageous port conditions of the port and drive regional economic development,many provinces(cities)actively promote the development strategy of “Developing cities with ports” and “The joint prosperity of the port and the city”.On the one hand,port logistics industry clusters can promote technological innovation within the cluster,drive the development of related industries,and attract labor force to agglomerate,which leads to regional economic growth;On the other hand,regional economic growth expands trade scale,promotes improvement of infrastructure,and provides essential factor resources and policies for the development of port logistics industry clusters.This article first discusses the theory related to industrial clusters and regional economic growth,and sorts out the literature on industrial clusters,port logistics industrial clusters,the Interaction between Port Logistics Industrial Cluster and Regional Economy;secondly,it begins with basic conditions of port and port logistics needs.Analyze the development status of port logistics industry in the Yangtze River economic zone,and then measure the level of the port logistics industry cluster in the Yangtze River Economic Zone by using the location quotient and the spatial Gini coefficient;again,this article construct the interaction mechanism between the port logistics industry cluster and the regional economic growth.Based on the analysis,a simultaneous equation model was constructed and the three-stage least square method(3SLS)was used to empirically test the interaction between port logistics industry clusters and regional economic growth in the Yangtze River Economic Zone;finally,corresponding countermeasures were proposed.The research shows that:(1)There are regional differences in the level of port logistics industry clusters in the Yangtze River Economic Zone.From the perspective of provinces and cities,the level of clusters gradually decreases from east to west;from the perspective of urban groups,the Yangtze River Delta Urban agglomerations have the highest level of clustering,but they have shown a downward trend in recent years.In contrast,the middle and middle reaches of the city and the Sichuan-Chongqing urban agglomeration have a low level of clustering,but they maintain a rising trend.(2)There is a significant positive interaction between the port logistics industry clusters in the Yangtze River Economic Belt and regional economic growth,among which the regional economic growth has a more pronounced role in promoting the port logistics industry clusters.From the perspective of the factors affecting the port logistics industry cluster in the Yangtze River Economic Zone,the industrial structure,port infrastructure,market openness,port labor force,and market size all have a positive effect,while the transportation infrastructure may have a negative effect on the port logistics industry cluster because of the limited competitiveness of the port.From the perspective of the factors affecting regional economic growth,the capital factor,labor force scale,human capital,and technical factors have a significant role in promoting regional economic growth.Although urban infrastructure and government investment can also promote regional economic growth,but the effect is not significant.
