These factors are examined in this article with three Total Factor Productivity models that examine the Greek manufacturing by specialization, by region and by firm size. The results give original information on the subject and provide the opportunity for forecast models. The forecast carried out is useful for possible policy making in the areas of both employment and regional policy.
