Estonia is considered one of the most liberal economies in the world, ranking 13th in the Heritage Foundation's 2009 Economic Freedom Index. Estonia's liberal economic policies and macroeconomic stability have fostered exceptionally strong growth. Its efficient agricultural sector employs some 11% of the labor force and produces meat (largely pork), dairy products, potatoes, flax, and sugar beets. Estonias major industry includes mining, shipbuilding, information technology, and the manufacture of wood products, electronic and telecommunications equipment, textiles and clothing, and machinery. Fishing is also important. Peat, phosphorite, clays, limestone, sand, dolomite, marl, and timber are important natural resources. The economy of Estonia is greatly influenced by developments in Finland, Sweden, and Germany, its major trading partners.
