Between the years 1910 and 1920 Ponta Grossa became the second largest economy in the state. The relapse of the economy surfaced in 1940, even during the crisis of 1929 the city managed to remodel itself. In addition, much of the area was a victim of deforestation of native vegetation, as well as other areas of Paraná that were sold to Buenos Aires and London. Ahead the municipality saw the solution in mechanization, in the concentration of capital, the division of factors of production and tasks. The Industrial District of Ponta Grossa was to share with Curitiba the development project for eastern Paraná, but in fact it was to concentrate industries in the capital of Paraná and leave the factories related to agriculture inland. The Industrial District was created in 1971, near the Cará-Cará neighborhood in the south of the city. The city hall gives ownership to industries. In the late 1970s Ponta Grossa became known as one of the main agro-industrial processing centers for soybeans. Until 1987 it was called the Botuquara Industrial District, but from that year on it became the Industrial District Mayor Cyro Martins. In 1992 the planned community determined that much of the right bank of the BR-376 towards Curitiba was destined as Industrial Zone. Between 2001 and 2007 there was an increase of 54.43% of the area occupied by industries.
