Of which:Marc Porat is with the macro-measure value of the information activities of GDP (GNP) or gross domestic product (GDP) ratio of the size, number of information workers, the proportion of total working population size and income information sector employed the proportion of national income to measure the size of the degree of social information.

Information Index is a method commonly used two algorithms: step arithmetic average method, first the index base year set the target of 100, respectively, measured in the same index value divided by the base year index value, obtained by the measured annual the index, then the index value index divided by the sum of the number of items, final information available index; two-step arithmetic average method, first calculate the average of four elements of the index, that index for each indicator values ??averaged, and then find the average arithmetic mean for this to get information technology index.
