The Yangtze River Delta region includes the Shanghai Municipality, the southern part of the Jiangsu Province, the northern part of the Zhejiang Province, and the neighboring seas. Covering an area of about 99,600 square kilometers, with a population of about 75 million, the Yangtze River Delta region has formed an industrial economic zone in the middle and south of Jiangsu Province and the north-east of Zhejiang Province with Shanghai as the leading city, and has established the development framework of "one body and two wings", i.e., the above seaport as the center, and the ports of Ningbo and Suzhou as the center of the development of the same port ****. The Yangtze River Delta port group is the port group with the densest port distribution and the largest throughput among the five port groups along the coast of China. In the process of economic globalization, the Yangtze River Delta region has become the region with the fastest economic growth in China. The growth of economy and trade has generated a large number of cargo sources, making the throughput and container throughput of ports in the region grow year after year. And the rapid development of port logistics,

makes the Yangtze River Delta region's rapid economic development.

Two, the Yangtze River Delta port logistics and the development of regional economic relations

The Yangtze River Delta region is currently China's fastest growing, the largest economic aggregate size, the most development potential of the economic plate. All along, the Yangtze River Delta has been closely linked with the outside world, the international market and the world economy. The Yangtze River Delta in the port logistics and the coordinated development of the regional economy there are greater advantages.

First of all, from an overall perspective, the Yangtze River Delta ports have formed a complementary advantage between each other, so that their hinterland economy generates an engine effect. Yangshan Port's advantage lies in the Shanghai port's more complete software service system and its comprehensive strength; and Ningbo - Zhoushan Port has Yangshan Port does not have more excellent natural conditions and water-water transshipment as well as large-tonnage bulk cargoes, the national strategic materials storage and transportation capacity. The opening of Yangshan Port means new development opportunities for Ningbo Port, the two ports can compete on the wrong side, complement each other's strengths, interdependence, to do *** with the development of the Yangtze River Delta from the overall enhancement of the port's gold content. The port itself is one of the important parts of the economy of the region, the production and operation of the port and the development of the regional economy can create direct output, national income, employment opportunities and taxes, and directly contribute to the development of the economic region.

Secondly, from the infrastructure point of view, the Yangtze River Delta within the completion of three major key projects to provide transportation support. Shanghai has established the Cross-Sea Bridge - East China Sea Bridge, an important supporting project for the deep-water port project of the Shanghai International Shipping Center. Zhejiang's Hangzhou Bay Bridge is currently the world's longest cross-sea bridge, which was built to greatly shorten the distance between cities in the Yangtze River Delta region, forming a 2-hour "Golden Triangle" traffic circle between Shanghai, Hangzhou and Ningbo, thus improving the "tightness" between these cities. This will increase the "tightness" between these cities and further form a synergy that will play a positive role in the regional economy. Hangzhou-Ningbo Canal renovation project connects the Qiantang River, Cao'e River, Ningbo River, three major waterways, and connected to the Beijing-Hangzhou Grand Canal, communicating with the eastern Zhejiang waterway network, the northern Zhejiang waterway network and the national waterway network, is conducive to perfecting the inland waterway network in Zhejiang, to enhance the collection and transportation capacity of the port of Ningbo - Zhoushan and to cultivate the advanced manufacturing base around Hangzhou Bay.

Once again, from the viewpoint of industrial structure, the ports have produced an optimization effect among themselves to achieve regional integration. The Yangtze River Delta port group can allocate resources and adjust the industrial structure within the region. Economic development can not be separated from a variety of resources, and there is an imbalance in the spatial distribution of resources, which needs to be regulated by transportation. The Yangtze River Delta port cluster enables various resources to be concentrated in the region and its surrounding areas, prompting more related companies, suppliers and related industries to concentrate accordingly, forming related industrial chains, promoting industrial upgrading of the regional economy, further expanding the opening up of the coastal area to the outside world, prompting the aggregation effect of regional and inland areas' economic and trade development, promoting the reasonable distribution of productive forces as well as adjusting and optimizing the industrial structure, and achieving the coordinated development of ports and logistics and the regional economy. Logistics and the coordinated development of the regional economy.

It can be seen that the Yangtze River Delta port logistics and regional economic development of the mutual promotion of the existence of greater advantages, but whether within the port or between the port, there are certain problems. These problems constrain the coordinated development of port logistics and regional economy, mainly in five aspects.

1, internal ports based on their own interests, the formation of competition. These ports in a small area to form a combination of dynamics at the same time, in the entire Yangtze River Delta range "self-contained system, the division of resistance," the willingness to increase. Based on local interests, local governments use administrative means to intervene in regional economic development, compete for cargo sources and seize the hinterland, leading to disorderly competition among ports.

2, government departments thinking concept misalignment, inadequate planning layout. The competent authorities of the Yangtze River Delta port group positioning is not clear, and there is no clear positioning of Shanghai, Zhejiang, Jiangsu, the two provinces and one city. At the same time, the role of the port of Shanghai, Ningbo port, Suzhou port division of labor is vague, difficult to coordinate the development.

3, the comprehensive transportation system is relatively imperfect. The internal and external transportation system of the Yangtze River Delta port group is still not perfect, and the scale is slightly insufficient. The construction of highway system lacks long-term planning and scientific management, and there is a lack of articulation and coordination between various places.

4, dock construction has a tendency to overheat, cargo competition is still playing the price war. At present, the Yangtze River Delta ports of the long-term planning throughput capacity of the total is close to 36 million TEU. And with China's economic development, the container increment may have a downward trend. Some ports are facing the problems of insufficient cargo sources and low port utilization. Various ports are constantly lowering port utilization fees and handling rates, leading to serious price competition. Price competition not only reduces port logistics revenue and inhibits regional economic development, but also leads to disorderly competition among ports.

Three, the Yangtze River Delta port logistics and the coordinated development of the regional economy countermeasures and recommendations

With the strong rise of the port economy, port competition has shifted from the cost differences in the competition to the quality of the competition, and then shifted to the competition for services. And in the service-centered competition, logistics service is the most important part of it. In the port logistics service, the optimal allocation of port resources is very important, the port needs to continuously expand its value-added service functions, through value-added services to achieve a reasonable allocation of resources, which can play a leading role in promoting regional economic development. At the same time, through the reorganization of logistics parks, the realization of regional port linkage and integration and the improvement of government regulatory efficiency, etc., to improve the port environment and enhance the value of port services. In order to further seize the development opportunities of port logistics and improve the competitiveness of the Yangtze River Delta regional economy, this paper puts forward the following suggestions.

1. Establish a leading organization to strengthen the integration of port group resources. The Yangtze River Delta port group belongs to Shanghai, Zhejiang and Jiangsu three different administrative regions, each government mostly for their own interests. Therefore, in accordance with the principle of optimal overall economic efficiency, the integration of port resources within the existing group needs to be involved in each region **** with. It is suggested that the state should set up a regional delimitation and industrial coordination committee according to the actual situation, and give it the corresponding power and resources to make it legalized and institutionalized. Then Ningbo-Zhoushan Port as the center, Shanghai Port and Suzhou Port coordinated development, to ensure the integration of resources within the port group, optimization and improvement, to achieve the purpose of "port city", and promote the Yangtze River Delta region's economic takeoff.

2, the development of port industry, fully relying on the advantages of port resources. The development of port industry is the best choice for developed countries and regions to utilize international resources and domestic resources. The development of large-entry, large-exit port-related industries and industrial belts in the Yangtze River Delta region can reduce the transportation costs of its intermediate links and improve the international competitiveness of its products. To comprehensively enhance the development of port-related industries, we should attach great importance to the development of port-related industries on the basis of the existing planning, take the ports in the cluster as a basis, promote industrial clustering, optimize the industrial layout, upgrade the industrial level, and work hard to build various industrial parks in the Yangtze River Delta. At the same time, the transformation and upgrading of ports will be strengthened, port equipment will be improved, port management level will be raised, service efficiency will be enhanced, service competitiveness will be strengthened, port environment will be governed, and structural contradictions within ports will be solved, so as to further strengthen the systematic construction of ports, improve the quality of services in the port area, and reduce the cost of logistics, so as to make the ports adapt to the needs of internationalization, marketization, and modernization.

3, expand the port logistics function, the establishment of modern logistics base. The ports should be organized to develop the logistics chain as the main task of its production and operation. According to the port cargo varieties, sites, machinery and equipment advantages, to attract upstream and downstream processing, transportation, warehousing and other logistics-related projects transferred to the port operation. To construct the logistics chain with shipping, highway and railroad enterprises *** with the material flow chain, to provide a full range of logistics services. To combine with the production enterprises and consumer market logistics, to carry out self-managed trade business and agency business, to develop the logistics market, the establishment of port trading market. The existing logistics parks, logistics centers and distribution centers should be combined organically to build a multi-functional and large-scale logistics base. Provide a solid foundation for port logistics, and provide enterprises with more comprehensive,
