Compare the growth of sectors/industries using the ADEPEF level 3 database, and the differences in rates for French and foreign companies (NATACT database). The study also focuses on the correlation between the variations of a company’s growth rate and its following characteristics: country of origin, legal form, size and proportion of shares held by foreign investors (PAYSTG, CJSIR, EFFDEF, EFFFRGR, ACPME and ACPMF databases). We will also see if industries develop as the number of parent companies rise.
