It is discovered that there exists a quantitative relationship, which can be expressed as \(G=kF(lgP)N\), where G is per capita GDP, F gross expenditure on R & D as percentage of GDP, P patent applications, N Internet users per 10,000 inhabitants, and k a constant ranging from 0.4 to 1.2 in most countries.
