It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial center. The constitution of France establishes the state as secular and democratic, with its sovereignty derived from the people.

France is among the world's largest economies. The country produces many items that other countries buy, including its most famous products: wine and cheese. Other exports include automobiles, electronics, and clothing. Tourism is also a huge industry in France. Some 75 million people visit the country every year, more than any other country. France actively supports companies to invest in R&D activities, mainly through the R&D tax credit. The R&D tax credit decreases the cost of R&D activities in France. According to several surveys, it reduces the cost of a researcher by one third, effectively placing the French researcher among the most efficient in the world. The R&D tax credit makes France one of the most competitive European countries.
France is also ranked 4th globally for the number of Nobel prizes (61).
