A high level of general and scientific education facilitates acceptance of innovations by society at large. Effective innovation systems require well-educated researchers, teachers, extension officers and business, and producers with a good general, technical and business education would generally be more willing and better skilled at adopting innovations. Between 2000 and 2011, the increase in public expenditures on education outpaced those in almost all OECD countries. Per student spending in primary and secondary education was more than doubled over this period, and was also increased for tertiary education but only slightly as expenditures were allocated across a nearly doubling of student numbers.
