La trasmissione dell’influenza nelle microfiliere del Friuli Venezia Giulia

Microchains influence transmission in Friuli Venezia Giulia region. The purpose of this paper is to verify the ability to transmit the influence, through the process of impulse/ response, in the traditional sectors compared to the corresponding quality food microchains. The technique used for this purposes is the graph of influence. Concerning the Italian agri-food system have used the data of the symmetric input-output tables (SIOT - 69 branches) made ISMEA. We then proceeded to collect the data budget and nonmonetary covering 30 quality microchains of Friuli Venezia Giulia chosen through a sample survey. Then we built SIOT tables to 69 branches. The next step was the implementation of a portable software (Visual Basic) for the determination of all the paths of influence (1, 2 and 3 arches) and cycles present in the ISMEA matrix of coefficients and in micro chains. Based on this analysis you can define a crosssectoral development policy capable of overcoming problems and to exploit the potential of food microchains.
