The port is a vital infrastructure that provides facilities and conditions for water and land transport, serving as a safe entry and exit point for ships. It acts as a natural interface connecting the inland hinterland and international logistics, making it a critical node in the global transportation network.

Port facilities comprise wharves, port equipment, cargo storage facilities, and means of transport, among others. A dock, which is typically a concrete or steel structure extending into the water, is used for loading and unloading ships and cargo.

Port equipment includes various cranes, loading and unloading machines, and transportation equipment. Cargo storage facilities consist of warehouses, storage yards, and tank farms. Means of transportation include boats, trucks, and trains.

Ports are categorized into inland and coastal ports, container, and oil and gas ports based on usage and cargo type.

Ports have played a crucial role in the economic development of countries by serving as a key link in transportation. Developed nations typically have their coastlines and well-functioning ports. Maritime transport is a critical mode of international commodity exchange, accounting for more than 80% of all international cargo transportation.

As an intersection of land and sea, the port acts as a gateway to the world and a hub for regional economic growth. The port's ability to radiate and drive the hinterland primarily depends on the transportation sector's internal and external aspects.

The more foreign-related routes and frequent port transportation, the more the regional economy's outward development can be promoted. The port's ability to radiate and drive the hinterland is strengthened by smoother, more convenient, and more complete channels between the port and the hinterland.

In addition to being the main transit points for goods, ports contribute to local and global economies by creating jobs and generating economic gains. They also play a crucial strategic role in trade and politics, and they can serve as a key component of national security as well as symbols of political and economic influence.

There are specific conditions that must be met for port construction. First, the development of port construction requires specific natural conditions, including an excellent geographical location, vast waters, necessary berth water depth, and good weather.

These are necessary guarantees for the long-term vitality of modern terminals. Additionally, a developed economic hinterland is required to provide a stable supply of goods for the port.

Second, a modern port must have a perfect and smooth collection and distribution system to become an essential water and land transportation hub in the comprehensive transportation network.

Finally, port construction requires significant capital investment due to the large investment scale and long construction period characteristic of transportation infrastructure. Therefore, entrants into port construction must have strong financial strength.

Ports play a critical role in facilitating international trade and economic development. They are essential components of transportation infrastructure, contributing to local and global economies, national security, and political and economic influence.

The development of ports requires specific natural conditions and a developed economic hinterland, and significant capital investment is necessary.
