up, and slowly the economy went down. The economy in Colombia around World War II was divided into two extensive periods: from 1930 to 1939, in which the country experienced a tremendous increase and a new social transformation. 1939–1945, the economy was stagnant, and at the same time, the social transformation was not progressing at all. Although some countries around the world had trouble coming back from the crisis, Colombia was one of the few that had a swift and sustainable recovery in order to develop its agricultural sector, coffee production, and oil exploitations. If we look at the economy from 1933 to 1939, we will see an extensive duplication in industrial production, growing by almost 11% annually; which no other country could accomplish. Although the increase was spectacular, we had to consider what the CEPAL organization said: “if we have a good growing rhythm, we need to think about the low initial level, which can cause future plans”. The investor ignored the organization's fundamental fact, which created new textile, shoes, and expanding food companies. By 1939 all of these developed a considerable increase in the domestic demand and nearly 2,805 manufacturing companies led to low import demand. Using these as a method wasn't as good as expected since other countries could see this as a closing trade action. Economy 1946–1958 Previous to 1946, there was a tremendous break down in the international and national economy due to World War II. The income per capita was lower than average, and export and import activities were more difficult than before. Colombia reacted with an “emergency economy” by intervening in the coffee industry by coordinating and controlling transportation by organizing external commerce and strengthening importation regulation system. Until 1946, Colombia didn't focus on creating more reforms but on recuperating from the War and boosting the economy. The fastest increase in economic activity was during 1946 through 1953, where the country changed its economic structure, and the international situation was healthier. Eventually, the investment amplified noticeably as a result of the best conditions of external payments. The industry structure was diversifying due to the accelerating industry and the fast process of urbanization, which created a tremendous internal demand in cooperation with the protectionist substitution of imports. Even though all the economic sectors were increasing their production rates, the industry had the most representing statistics of development and modernization. In eight years, the industry
