• Agglomerations
• Lock-ins.
• Variety

This work does two things. On one hand, it verifies inter-sectoral differences in terms of agglomerative strengths and patterns; while, on the other, it examines the relation between agglomerative tendencies and regional industrial variety for some of the most agglomerated sectors. The analysis uses Italian data from four Census of Manufactures and Services (1971, 1981, 1991, 2001).
