MARQUEZ CONTRERAS, Trifina Elizabeth et al. Determinant factors in the technical efficiency of bean farms. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.spe11, pp.2067-2073. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v0i11.774.

The technical efficiency of 30 bean farms located in Portuguesa State, Venezuela was evaluated considering five inputs and one product that was related to socioeconomic and geospatial variables. The Data Envelopment Analysis (DEA) method was used, a product-oriented model. According to the results, on average, the overall technical efficiency (ETG) was 81.2%, broken down into pure technical efficiency (PTE) of 86% and scale efficiency (EE) of 95.1%. Inefficiencies caused by technology are higher than those generated by a suboptimal size or scale of production. According to the planning goals, we can increase the aggregate bean production by 23.1% without increasing the amount of current applied inputs. The socioeconomic and geospatial variables did not determined the levels of technical efficiency on the farms.
