One of the variables essential to understanding economic growth is the analysis of capital accumulation. The Ivie, in collaboration with other institutions, builds databases with information on different assets, tangible and intangible, that make up the capital stock in Spain. One of the databases with which the Ivie has the longest experience and has earned most recognition is El stock y los servicios de capital, developed since the mid-1990s. During the last decade, the analysis and construction of databases have included also intangible assets which are a key factor in the development of the knowledge economy.
The investment and capital stock series, both tangible and intangible, offer national and regional data covering long periods of time by asset type, industry and institution (public or private).
