Globalization has brought about a sharp increase in the real and financial integration in the worldwide economy. In this closely knit context, the outsourcing of some of the productive and trade activities abroad has become the focal point of the policies followed by firms in order to face competition on international markets. The shift of manufacturers towards countries with lower labour costs was underlined by some experts at the beginning of the 1970s and especially involved countries with relatively high labour costs such as USA, Germany, Sweden, Denmark, U.K. (Adam, 1971; Finger 1976; 1977). Over the last decades the capacity of manufacturing firms to slice the production cycle without incurring high diseconomies has given large impetus to production globalisation and has driven firms in countries with salaries lower than those in the USA and North European countries, like Italy, to find lower production costs abroad. Additionally the participation of East European countries, Russia, and China to the international consumption market has provided an additional incentive to transfer the manufacturing processes abroad by locating outposts in areas close to markets with high sales potential.
To ‘measure’ the degree of internationalization of a firm is not an easy task: the usual measure is the value of the direct overseas investments made to set up a new company abroad or to purchase one already in existence. Italian overseas investments are modest, and Italian businesses seem to be lagging behind compared to other industrialised countries of a similar size and degree of development. Some scholars who have acquired information from the study of interindustrial trade flow (Schiattarella, 1999; Kaminski and Ng, 2001; Corò and Volpe, 2003) and from studies on individual companies have reached the conclusion that the process of internationalisation is much wider and detailed than what appears from data regarding direct investments. A conspicuous part offirms’ overseas activities is in fact based on intermediary procedures i.e. trade agreements and subcontracting, particularly important in the case of Italian SMEs (Bigarelli and Ginzburg, 2005). These forms of ‘light’ integration involve reduced capital flows and temporary commodity flows, as commodities are sent abroad in order to be processed and are subsequently re-imported. But intermediate commodity flows blend with the ‘normal’ transit of goods at Customs, they are not separately recorded, therefore they are difficult to identify. Because of this and not because ’light’ integration is unimportant, international trade experts have not really taken it into consideration (Bugamelli, Cipollone e Infante, 2000).
