Bottom-Up or Top-Down： Which Is the Best Approach to Improve CSR and Sustainability in Local Contexts？ Reflections From Italian Experiences

This paper reflects on the theme of sustainability and territorial social responsibility, which, in this context, is defined as a pathway promoted by a plurality of public and private actors, for- and non-profit, who find that social cohesion and the relationships that are cultivated in the place from which these diverse ＂protagonists＂ come, are the drivers in the construction of shared territorial governance. The efficacy of such processes in the local context （communal, provincial, and regional） is predicated on the culture and on the values that the diverse, networked stakeholders-actors accumulate in their territory （meso level）. In developing this theme, the paper is divided into several parts. The first part describes the theoretical context, which is illustrated by an enumeration of experiences realized at the local level in Italy. We then focus our analysis on the experience of territorial govemance promoted in the Marches Region. This project was selected as a case study, because it is emblematic of the Italian context; the territory is characterized by the diffuse presence of small businesses in the soeio-economic fabric and by the proactive role of the local government. The case allows us to evaluate this paper＇s fundamental proposition, that the policies of the European Commission [EC] and the Government of Italy for promoting Corporate Social Responsibility and sustainability are not concretely effective when they are not fostered by regional authorities together with local private actors. Furthermore, public initiatives, to be effective, should take into consideration the influence of local culture, the social milieu, and economic factors shaping the environment in which public-private networks arise.
