Agriculture plays an important role in Iran's national economy.

Iran is rich in agricultural resources. The country's arable land area exceeds 52 million hectares, accounting for more than 30% of its land area. The cultivated area is 18 million hectares, of which 8.3 million hectares are irrigable land and 9.4 million hectares of dry land.

The agricultural population accounts for 43% of the total population, and the average cultivated land per farmer is 5.1 hectares.

The degree of agricultural mechanization is low, and the number of integrated harvesters and tractors is 13,000 and 360,000 respectively.

The Iraqi government attaches great importance to and vigorously develops agriculture, and has achieved 90% self-sufficiency in food production.

The main agricultural production areas are concentrated in the coastal plains of the Caspian Sea and the Persian Gulf, and most areas are dry and short of water.

Since 2003, the Iranian government has increased its agricultural support year by year, focusing on supporting the construction of farmland infrastructure such as water conservancy and irrigation, as well as agricultural scientific research, credit and natural environment protection, in order to improve the farming environment, increase farmers’ enthusiasm for production, and strive to achieve the government’s fourth five-year plan.

The industry growth target of 13.5% is set in the annual socio-economic development plan.

Iran's main industry is oil extraction, and there are also oil refining, steel, electricity, textiles, automobile manufacturing, machinery manufacturing, food processing, building materials, carpets, household appliances, chemicals, metallurgy, papermaking, cement and sugar making, etc., but the foundation is relatively

Weak, most industrial raw materials and spare parts rely on imports.

As of 2001, there were 13 public and private automobile manufacturers in the country.

Two of them, Iran Khodro and Saipa***, account for 94% of local production.

Iran Khodro produces Iran's most popular brand Paykan, which was later replaced by Samand in 2005.

Iran Khodro still held the largest market share in the country in 2001, accounting for 61%, while Saipa accounted for 33%.

Other automobile manufacturers, such as Bahman Group, Kerman Motors, Kish Khodro, Raniran, Traktorsazi, Shahab Khodroh, etc., account for only the remaining 6%.

These car manufacturers manufacture many types of vehicles, including e-bikes, passenger cars (such as Saipa's Tiba), and various types of trucks, minibuses, buses and other heavy vehicles for domestic commercial and private use.

In 2010, Iran was the twelfth largest automobile producer in the world, with an output of 11.5 million vehicles.

Automobile production exceeded one million units in 2005, and auto exports are expected to reach US$1 billion in March 2009.

Since 1920, Iran began to gradually develop large-scale production machine rooms.

During the Iran-Iraq War, Iraq bombed Iran's petrochemical plants and the Abadan oil field, causing oil production to slow down.

Reconstruction of the refinery began in 1988, and normalcy began in 1993.

However, during the war, many small factories also appeared to produce military supplies for the army.

The country mainly produces petrochemical products, steel and copper products.

Other major products include automobiles, household appliances, communication equipment, cement, industrial machinery (Iran has the largest machinery industry in West Asia), paper, rubber products, agricultural products, processed foods, wool products, and pharmaceuticals.

The textile industry provides cotton and wool locally and employs 400,000 people, 2,000 of whom are in Tehran, Isfahan and the Caspian Sea coastal areas.

According to The Economist, Iran ranks 38th in the global industrial rankings, with a GDP of US$23 billion.

From 2008 to 2009, Iran's industrial production growth value jumped from 69th to 28th.

A 2003 report by the United Nations Industrial Development Organization pointed out that the obstacles to the development of small and medium-sized enterprises in Iran include lack of supervision, no effective banking system, lack of research and development, lack of management skills, corruption, poor tax system, cultural fear, educational restrictions, failure to internationalize,

Insufficient labor skills, lack of intellectual property rights, insufficient research centers, insufficient social learning, and traditional cultural influences.

However, recent research also indicates that Iran has experienced rapid development in various fields, including technology, medical care, aerospace, national defense and heavy industry.

Under the economic sanctions imposed by the United States, the country quickly became an industrialized country.

Affected by economic freedom and government spending, including the depletion of funds established by the government.

It is estimated that the service industry's revenue exceeds 25% of GDP. Expenditures mainly come from daily government expenditures, including military, salaries and social services.

Urbanization has stimulated the service industry.

Important service industries serve the public and include education, commerce, personal services and tourism.

Revenues from Iranian science amounted to US$900 million (2005), but there has been no significant growth over the past 15 years.

In the early 2000s, Iran adjusted its R&D GDP contribution to 0.4%, lagging behind the developed country average of 1.4%.

In 2009, it will account for 0.87% of the total national GDP and will reach 2.5%.

The total GDP of transportation and communications is expected to increase to US$46 billion in 2013, accounting for 6.8% of the country.

According to the International Labor Organization's 1996 recommendation, Iran employed 3.4 million people in transportation and communications, which increased to 20.5% of the labor force in 2008.

Iran has a history of civilization spanning thousands of years and is rich in natural geography and ancient civilization heritage.

Before the Islamic Revolution, millions of people visited Iraq every year.

After the Iran-Iraq war, the tourism industry was greatly damaged.
