For the Romanian economy, in general, and for the rural area, in particular, the demographic evolution represents a significant component the dynamics and structure of which depend on the sustainable economic growth rate. The common East and West European problems are the following: population ageing, proportional (and often also absolute) decline of the labour force and the education. The deficits in Western countries are partially covered by the East-West migration flows for work, but these labour force movements generate similar problems on the labour markets in the origin countries, in East. All these changes have a direct influence on the national and regional economy, in origin or destination countries. The conclusions of the study show that, for rural area, the entrepreneurial sector development represents an important component whose dynamics and structure influence the sustainable economic growth rate. A successful private initiative depends not only upon the entrepreneurs’ innovating capacity but also upon the available teritorial labour force, whose characteristics (age, education and experience) influence the rate of innovation adoption at the level of firms.
