Vitali G., Filippi M., Manello A., Working Paper Cnr-Ceris, N° 14/2012 Further important evidence about the specialization of ethnic groups in specific economic activities can be derived from Bates (1999), regarding Asian immigration in the US, but also from Sahin et al. (2011) in the case of Germany. Aguileira (2009) argues that an important issue could be the concept of ethnic enclave, defined by Portes and Jensen (1989) as a special network firm which is managed by ethnic minority groups. Finally, other geographical factor could influence the localization choice of ethnic entrepreneurs: Fairchild (2008) argues that racial discrimination is correlated with the presence of minority’s enterprises in urban areas, in US for the case of black and white antagonism. Major interactions between local context and a higher presence of ethic entrepreneurship are highlighted in recent contributions, in particular for what concerns US metropolitan areas (Wang and Li, 2007). 3. SELF-EMPLOYMENT RATE BY COUNTRY OF ORIGIN Table 1 shows the links between population and foreign entrepreneurships6: within the period 20042009 the foreign population7 growths by 80%, from 2.25 million to more than 4 millions. Some ethnic groups8 growth more than the others: Romanians and the other Eastern EU countries growth a lot, 6 Our study is based on the database ISTAT-ASIA (Archivio Statistico delle imprese Attive). ASIA collects all the Italian firms that produce a turnover at least six month per year, that have at least one employee or self-employee. Within the period 2004 – 2009 some events affect the statistical data: new provinces have been set up, there was a new classification of economic activities, the EU has been enlarged to Romania and other East-European countries. 7 The source of the population data at province level is ISTAT DEMO database, that provides population but not its age or gender. In our tables, the total of the foreign population considers all the foreign countries, except Western EU (12), USA and Canada, in order to be homogeneous with the non-EU immigrant characteristics. 8 We elaborate the characteristics of the foreign entrepreneur according to the information of its fiscal code, which reports the gender, the date of birth, the country of birth. Other information concerns the firm, such as its location (at municipality level and even ZIP postal code), its sector of activity (ATECO 2007 code), its turnover (by class size), the number of employees. more than 100%, thanks to the 2004 enlargement of the EU. In 2009 the Rumanian community is the strongest in Italy, with about 900 thousand of people they represent the 22% of total foreign population, followed by Albanians (11%) and Moroccans (11%). Within the period, Romanians growth by 257%, Polish by 108%, and Bangladesh population by 107%. On average, the dynamics of micro firms is lower than the dynamics of population, as the total number of micro firms growth by 40%, from 113,000 to 160,000. The strongest ethnic groups, as far as the number of micro firms is concerned, are the Chinese, that represent the 17% of total foreign micro firms, followed by Romanians (13%) and Albanians (12%). Within the different ethnic groups there are different dynamics, as Russian firms growth by 147% and Romanians by 130%. If we compare the dynamics of population and the dynamics of micro firms we find some countries that increase the firms more than population: micro firms from Albany increase by 80% and population by 47%, and from Russia the rates are 147% versus 107%. On the contrary, the population growths more than micro firms as far as Romania, Poland and Bangladesh are concerned. The distribution of the micro firms is affected by some variables at local level, such as unemployment rate, foreign population rate, and so on. These variables have a different geographical distribution in Italy, and therefore the foreign micro firms have not a homogeneous distribution in the Italian regions and provinces. First of all, the distribution of foreign population and foreign micro firms follows the level of the economic development, with a strong presence in the North of Italy: North-West represents the 35% of population and micro firms, and in North-East the rates are 27% and 25% accordingly. On the contrary, South of Italy collects only 13% of population and 14% of micro firms. 7
