Community Development Banks (BCD) are experiences that belong to the phenomenon of the solidarity economy. BDCs are currently present in peripheral and rural communities in 114 Brazilian municipalities. In 2010, the Public Call no 03/2010 carried out by the defunct National Secretariat for Solidarity Economy (SENAES, 2003 - 2016), within the Solidarity Economy in Development Program, promoted the implantation of BCD by several Brazilian regions as one of the objectives of promoting “Sustainable and supportive local development”. In the northeastern region, it implemented five Community Banks, one in an urban peripheral community and four in rural areas. Thus, the comparative premise emerges as a research question: is the development of a Community Bank in the rural context different from the urban one? Seeking an answer to this question, the general objective of this investigation is to compare a development perspective in which Community Banks are sustained, based on the following specific objectives: I) Categorize which communities are involved in these initiatives; II) Describe the activities that the BCD performs; III) Analyze the sustainability of its operations, and; IV) Compare how these experiences understand development for their communities. For that, we used as a cutout two experiences, the first located in the peripheral community of São Rafael in João Pessoa / PB and; the second present in the rural community of São Miguel do Gostoso/RN. In the research findings, the evidence in common and differences enables a comparative study oriented to the case of Ragin (1987), combined with the techniques of action research, descriptive and semi-structured research that will be carried out with the agents of these initiatives, following Mirian's guidelines Goldenberg (2004), with subsequent analysis of the content according to the structural deciphering of Bardin (2001) around the following axes of analysis: categorization of the community; favorable solidarity dimensions for the
sustainability of BCD, and; development perspective.
