The territorial economic specialization of the Santarém Region represents a prominent identity mark and is due, in large part, to the quality and variety of its natural resources, with an abundance of water resources, fertile soils and the proximity to raw materials, and the diversity and quality of endogenous products. In this context, it is important to carry out an analysis of the sectors with a high level of implementation on the Region and where exists a very high potential for subcontracting.

Taking into account the distribution of the turnover of companies in the Santarém Region, and suppressing the interference of large companies, the existence of five major groups of activities is highlighted, generating differentiating service products, with a very significant weight to the regional economy, namely: agri-food, tanneries, wood and paper, metalworking and natural stone.
