The fact that there are no large towns in Venetia has meant that factories are distributed all over the region allowing fairly uniform economical growth, with lower risks of water and atmospheric pollution. This cannot be said, however, of the Porto Marghera area which has a high concentration of industry. A relevant factor regards part-time farming by industrial workers. The quantity of livestock owned is considerable, especially for cattle and pig breeding. Fishing is important and Venetia occupies fifth place on the national scale, providing large quantities of fish and seafood.
Fish farming is an important new development in the lagoons and Po Delta area.
Industry is characterized by the presence of small and medium-sized firms and is traditionally strong in certain sectors. The Porto Marghera industrial complex represents one of the major concentrations of Italian industry with chemical and petrochemical plants, metallurgical and engineering works and thermoelectric stations. Commercial and financial activities are concentrated in the provincial capitals, especially Venice where there is a busy commercial port, and Verona , an important freight distribution centre on the communication routes to and from Central Europe. A characteristic of the banking sector is the presence of banks of Catholic administration. The communications network is well developed, due also to the fact that Venetian territory is mainly on the plain.
