Under the doctrine of ''Dirigisme'', the government historically played a major role in the economy; policies such as indicative planning and nationalisation are credited for contributing to three decades of unprecedented postwar economic growth known as ''Trente Glorieuses''. At its peak in 1982, the public sector accounted for one-fifth of industrial employment and over four-fifths of the credit market. Beginning in the late 20th century, France loosened regulations and state involvement in the economy, with most leading companies now being privately owned; state ownership now dominates only transportation, defence and broadcasting. Policies aimed at promoting economic dynamism and privatisation have improved France's economic standing globally: it is among the world's 10 most innovative countries in the 2020 Bloomberg Innovation Index, and the 15th most competitive, according to the 2019 Global Competitiveness Report (up two places from 2018).
