Algeria

Ma Jianming

Algeria is located in northwest Africa, with a land area of 2.38 million square kilometers and a population of 33.2 million, most of whom are Arabs. Algeria ranks second in Africa, second only to Sudan, and third in economic scale, second only to South Africa and Egypt. Most of Algeria's population lives in the northern coastal area, and the rest is covered by the Sahara desert. Rich in oil and natural gas resources, it is known as "North Africa oil depot". The oil and gas industry is the backbone of Algeria's economy. Most oil and gas products are exported, and the export income of natural gas and oil accounts for more than 90% of the country's foreign exchange income.

In 2006, Algeria's GDP was about US$ 654.38+005 billion, per capita GDP was US$ 3,443, economic growth rate was 5.2%, foreign exchange reserves were US$ 77.78 billion, foreign debt was US$ 5 billion, and total import and export volume was US$ 73.8 billion. Thanks to the stable political situation, stable oil export and good financial situation, Algeria's economy has maintained a high-speed growth momentum.

Four. Mining policy

Algeria promulgated the investment law on 1993, encouraging private investment and giving many preferential policies, giving foreign investors national treatment and actively attracting foreign investment. The investment bill stipulates that: except for strategic sectors restricted by the state, a free investment policy shall be implemented; Foreign-funded enterprises and domestic-funded enterprises pay the same income tax at a rate of 42%. However, priority projects that meet Algeria's national economic development plan are exempt from tax for the first three years, and the tax is reduced by 50% and 25% in the fourth and fifth years respectively. Foreign-funded enterprises are exempt from land tax for five years. At present, the investment law has been continuously improved and implemented well.

The oil and gas industry is the most important industry in Algeria. According to the Algerian oil and gas law, the Algerian government levies 85% corporate profit tax on SONATRACH and foreign oil companies engaged in oil and gas exploration, development and refining in Algeria, which can be reduced to 75% or 65% depending on the implementation area. Algerian national oil and gas companies and foreign oil companies engaged in oil and gas pipeline transportation, natural gas liquefaction and oil and gas separation in Afghanistan are subject to 38% corporate profit tax, and the professional behavior tax and value-added tax of the above companies are exempted.

At present, investors in Algeria mainly include Egypt, the United States, France, Spain, Italy, Germany, Saudi Arabia, Jordan and other West Asian countries. In terms of oil and gas development, 1986, Algeria allowed foreign capital to set foot in the oil and gas field for the first time. So far, Algeria has signed more than 50 cooperation agreements with nearly 20 countries including the United States, Britain, France, Italy, Spain, Japan and China, and nearly 50 international oil companies have come to Algeria to participate in oil and gas exploration and development. Up to now, the total foreign investment attracted by the oil and gas sector in Afghanistan has exceeded 654.38+0 billion US dollars. Among many companies, American oil companies rank first, with an investment of over US$ 5 billion, accounting for 35%, followed by Italian, Australian, British, Canadian, French, Spanish and China.

Algeria has a controlled floating exchange rate system, and the central bank controls all foreign exchange resources.

As one of the world's largest export credit guarantee financial institutions and authoritative economic organizations, France Foreign Trade Insurance Company ranked Algeria as a B-level, that is, a small-risk investment country according to seven indicators in 2004, including political stability, foreign exchange reserves, repayment ability, currency depreciation risk, bank risk, economic situation and payment status.

Verb (abbreviation of verb) view

Because Algeria is close to Europe and rich in oil and gas resources, Algeria's oil and gas industry has always been the main sector to attract foreign investment. Algeria is a member of the Organization of Petroleum Exporting Countries, and its oil production is limited by the production quota of the Organization of Petroleum Exporting Countries. At present, the Algerian government plans to increase oil and gas production and increase oil and gas exports.

The Algerian government is actively expanding natural gas exports. At present, Algeria is connected with Europe through two natural gas pipelines. One is a trans-Mediterranean pipeline, with a length of 1.078km and a transportation capacity of 65.7 million m3/ day, which starts from Hasilumel gas field and finally reaches Italy via Tunisia. The other is the Maghreb European natural gas pipeline, with a length of 1.609km and a transmission capacity of 23.22 million m3/ d, connecting Hasi Rumaille gas field and Spain through Morocco.

Algeria also plans to build three new natural gas pipelines: Medgaz natural gas pipeline between Algeria and Europe, which is expected to be completed in 2008; The new pipeline between Algeria and Italy is expected to be put into use in 2008; A new 7 160km gas pipeline will be built between Wali gas field and Hasrumaille gas field.

With the growth of oil and gas production and export, Algeria has become an important supplier of international energy market.

Algeria is the second largest producer of lead and zinc in Africa, and has made great discoveries in recent years. With the rising price of lead and zinc in the international market, the exploration and development of lead and zinc may also provide important opportunities for the development of Algerian mining industry.
