For this reason, a sbarp increase in the importance of the manufacturing sector was to have been expected during these 25 years a funceion of their develoPnent. Instead, measured by the changing proportions of output originating 1n the major economic sectors (see cable 50), this process of structural change oas sloid or non-existent in many developing countries. The share of manufacturing remained about the same ln 1980 as it was in 1960. and little increase in the tmportance of industry in general can be noted outside of the petroleum-expor ti ng econonies. l,breover, in many disadvantaged countries where the share of agrlculture did fall noticeably, it has been more a consequence of deteriorating agricultural performance than tbe successful development of industry and manufacturingt in stlu. other countries the service sector accounts for much of the perceived change in economtc structure, and the commodity-produc ing sectors achieved no positive atructural change in the form of inprovements to the organizatlon' techniques and basic facllities underlying the production of comnodity goods and basic servlces.Table 50.
