Findings top

  • From 1993 to 2001, the number of academic publications remained fairly constant at 140,000–150,000 annually.

  • In 2001, academic researchers produced an average of 4.5 publications per $1 million academic R&D, compared with 7.3 in 1993. This partly reflects the effects of general price inflation but may also indicate rising academic research costs.

  • The value of this indicator decreased for all states between 1993 and 2001.

Description top

This indicator shows the relationship between the number of academic publications and the expenditure for academic research and development. A high value for this indicator means that a state's academic institutions have a high publications output relative to their R&D spending. This indicator is not an efficiency measure; it is affected by the highly variable costs of R&D and by publishing conventions in different fields and institutions and thus reflects variations in field emphasis among states and institutions.

Publication counts are based on the number of articles appearing in a set of journals listed in the Institute for Scientific Information's Science Citation Index and Social Sciences Citation Index. The number of journals was 4,601 in 1993, 5,029 in 1997, and 5,262 in 2001. Articles with authors in different institutions were counted fractionally. For a publication with N authors, each author's institution was credited with 1/N articles. In this indicator, Maryland data exclude expenditures by the Applied Physics Laboratory at the Johns Hopkins University.
