An aspect of the organization and functioning of local government system, which appears more often in public speeches and research studies is inter-municipal cooperation. IMC is when two or more municipalities agree to work together on any of the tasks assigned to them in order to gain mutual benefits. IMC is not a concept emerged spontaneously. The emergence and development of the concept was preceded by administrative and economic processes carried out in 60-70 years last century in Western Europe, and a little bit later in CEE countries. Excessive administrative-territorial fragmentation, the minimum of local public services, which are expensive and of poor quality, high spatial development disparities, etc. are the main arguments for taking into account the European good practices of IMC and implementing them in Moldova.
