The objective of this paper is to verify the structural panorama, the dynamics of growth and the technological strategies used in sugar cane agro-industry in the State of Parana. It was implemented the shift-share model, to quantify the sources of agricultural production growth from 1981 to 1998. Besides sugar cane, was also analyzed the following cultures: cotton, coffee, soy and corn. It was made a questionnaire to get information from Parana; s sugar cane factories and distilleries, about the harvest of 1997/1998. It can be inferred that this agro-industry left the condition of a small importance to assume a national prominence position. In Parana, the sugar cane was the one that had the greater growth of production, which was achieved by the increase of the cultivated area. It was motivated by its high productivity and the influence of PROÁLCOOL. The sample of the searched units showed the good use of the sugar cane by-products and the use of agricultural and mechanical advanced technologies. This has been reflected in high agricultural and industrial productivity, corroborating the technological development which has passed the sugar cane agro-industry of Parana.
