With the progress of social civilization and technological development.

The role of transportation is extremely important in today's society and even in many fields around the world, covering a very wide range and use, more advanced transportation is also emerging.

But today is to say that the transportation hub rather than transportation, but now the status has been among the world's forefront.

The influence of many countries can not be compared, this hub is the port.

Port is an important transportation hub connecting land and water, as early as 2700 years in Crete, Greece, there is the world's earliest and most primitive port site.

China established an early large port for foreign trade in the Han Dynasty: the port of Guangzhou.

Since then, more ports have been established for commercial purposes, but the development of modern ports has only emerged since the introduction of the steam engine in the 19th century.

And the construction of ports has connected the world together, which can be credited with the development of all countries and the progress of world civilization.

Ports have always played an important role in the economic development of a country.

Transport links the world together, and ports are an important part of that transport.

The world's developed countries generally have their own coastlines and more functional ports.

The functions of ports can be summarized in the following four aspects.

1. Logistics service function.

The port should first provide comprehensive logistics services for ships, cars, trains, aircraft, cargo, containers, such as transit, loading and unloading and warehousing, especially to improve the logistics services of multimodal transport and distribution processing.

2. Information service function.

Modern ports should not only provide users with information and consultation on market decisions.

But also build a value-added service network of electronic data interchange (EDI) systems to provide customers with order management, supply chain control, and other logistics services.

3. Commercial function.

The existence of the port is both the premise of commodity exchange and the existence of domestic and foreign trade and promotes their development.

Modern ports should provide users with convenient transportation, commerce, and financial services, such as agency, insurance, financing, freight forwarding, shipping agency, customs clearance, etc.

4. Industrial function.

The establishment of modern logistics needs a platform with the function of integrating productivity factors.

As the interface point between the domestic market and the international market.

The port has realized a comprehensive large circulation from the traditional cargo flow to the flow of people, goods, commerce, capital, technology, and information, and is the gathering point of goods, capital, technology, talents, and information.

International freight is being accelerated from isolated practitioners of piecemeal to modern logistics systems to better meet the individual needs of different customers.

Therefore, the port is required to play a more active role in the modern logistics system.

Traditional port activities have only transit and product distribution functions.

With the development of international multimodal transport and the increase in complexity of the integrated transport chain.

The functions of ports as nodes of the globally integrated transport network will also be more extensive.

Modern port functions are constantly expanding inland with the port as the center, providing convenient transportation, and commercial and financial services for customers.

And its functions are also developing toward providing a full range of value-added services.

The expansion of port functions is not only the requirement of modern logistics development but also the embodiment of the port's role in promoting the development of modern logistics.
