Information and communications technology: The Role of ICT in the World Economy

Information and communications technology (ICT)refers to all technologies and devices used in managingand processing information systems. In contrastto the manufacturing industries such as shipbuilding,steel, automobiles, and textiles, whichcreate value directly, ICT in the form of computers,software, the Internet,multimedia, andmanagementof information services creates value indirectly. ICTincludes data for business use, voice communication,images, multimedia, and many types of technologiesfor the purpose of development and exchangeof information. The definition of the ICTsector differs among industrialized countries. TheU.S. and Organisation for Economic Co-operationand Development (OECD) definitions are presentedin table 1.

The introduction of increased processing powerof hardware alongwith complementary software andtelecommunications infrastructure have enhancedthe ability to store, retrieve, analyze, and communicatedata and information within and between organizationsand their partners and suppliers, andultimately to the consumer. In particular, ICT dealswith the use of electronics, computers, and computersoftware to convert, store, protect, process, transmit,and retrieve information. For that reason, computerprofessionals are often called information technology(IT) specialists or business process consultants, andthe division of a company or university that dealswith software technology is often called the IT department.Other names for the latter are informationservices, management information services, ormanaged service providers.

As a general rule, capital and labor as importantelements in the growth of an economy lead to decreasingreturns to scale. Therefore, even thoughthese factor inputs of production may increase, thegrowth of an economy over a certain level cannot beexpected. Information may produce increasing returnsto scale and become an important factor forsustainable growth, however. Thus, in recent years,ICT has been considered an input in the productionof goods and services and a factor affecting totalfactor productivity growth at both themicro- and themacro levels (see Shiu and Heshmati 2006).
