September2025 NationalAccountsStatisticsDepartmentBankofKorea 1.Overview □The 2023Input-OutputStatisticsare compiledat currentprices basedon the2020benchmark,usingmainly themodified RASmethod. □The 2023 Input-Output Statistics include the input-output tables,as well astheemploymenttables. 2.TotalSupplyandDemandfromtheInput-OutputTables □The total supply(total demand)of goods and services in 2023 amounted to6,802.7trillionwon(at producer’sprices). ―Domestic output accounted for 85.1%of this total supply,and importsfor14.9%.The share of domestic output was 1.1%p larger than the84.0%figure for2022. ―About 50.0%of the total supply was used as intermediate goods fordomesticproduction,while 35.3%was used to meet domestic finaldemandandtheremaining 14.7%wasexported. □The share of exports plus imports decreased by 1.9%p,from 31.5%in 2022to29.6%in 2023. ―This was due mainly to a decline in the prices of raw materialsincludingcrude oil and LNG,as well as to a decrease in export andimportvolumes. 3.IndustrialStructure □Services accounted for 48.1%of total domestic output and 65.4%of totalvalueadded,andmanufactured goodsfor 41.2%and 25.0%respectively. ―The ratios ofmanufactured goodsto totaloutput andto valueaddedfellby1.6%p and 1.2%p,respectively,compared to 2022,while theproportionsofservices roseby 1.3%p and0.3%p,respectively. □The composition of value added increased by 1.1%p in the electricity,gas,andwatersupply,waste managementcategory. ―The composition of value added increased in services,primarily drivenbyfood servicesandaccommodations 4.IntermediateInput □The intermediate input ratio fell from 59.9%in 2022 to 58.8%in 2023.Inaddition,the import dependency ratio decreased from 14.9%to 13.6%duringthisperiod. ―The intermediate input ratio of manufactured goods declined during theperioddue to falling prices of imported raw materials,such as crude oilandnatural gas. ―Accordingly,localization rates of intermediate inputs rose by 1.9%p from75.1%in 2022to77.0%in 2023. *Localization rate=[domestic intermediate inputs÷(domestic intermediate inputs+importedintermediate inputs)]×100 Unit:% 5.FinalDemand □Consumption made up 48.0%of total final demand,while investmentaccountedfor 22.6%andexports 29.4%. ―The shares of consumption(45.8%→48.0%)rose during the year from2022to 2023,while that ofexports(31.3%→29.4%)decreased. □Among private final consumption expenditures,the share of services rose(73.1%→74.0%)whilethatofnon-durablegoods(15.4%→14.8%)decreased. □The shareof constructioningrossfixedcapital formationincreased(40.6%→41.4%),while that of machinery and equipment(13.0%→12.1%)declined infacilitiesinvestment. 6.Exportsand Imports □Looking at exports of goods and services in 2023,those of manufacturedgoodsaccounted for 81.3%of the total,while exports of services made up18.5%. ―The composition of export products showed a mixed trend,with a0.5%pincrease in the proportion of manufactured goods and a 0.5%pdecreaseintheshare ofservices. □As tothe composition ofimports in 2023,manufactured goods imports heldashare of 61.2%of the total,followed by mined and quarried products(21.5%)andthenservices(15.6%). ―The change in the composition of imports between 2022 and 2023 wassignificantin mined and quarried products(25.0%→21.5%)and in services(12.7%→15.6%). Unit:% 7.Inter-IndustryEffects □The production requirement coefficient*increasedfrom 1.817 in 2022 to1.827in2023. *The production requirement coefficient for a certain product measures the amount ofproductioninduced,both directly and indirectly,by an additional unit of final demandforthat product. □The value added requirement coefficient increased from 0.729 in 2022 to0.752in2023,whiletheimport requirementcoefficient(0.271→0.248)fell. 8.Employment Structure □The number of employed persons(full-time equivalent)amounted to 25,989thousandsin2023,havingincreasedby2.2%from24,432thousandsin2022. ―The share accounted for by regular workers rose(59.6%→61.0%),whilethatof temporary or daily workers(15.4%→14.5%)and that ofself-employedorunpaid family workers(25.0%→24.5%)both declined. ―By commodity,the share of employment accounted for by services(71.1%→71.7%)washigherthanthatin2022,whilethoseofmanufacturedgoods(14.8%→14.5%)and of construction(7.4%→7.2%)werebothlower. (Unit:1,000persons,%) 9.Employment InducementEffects □The workerscoefficient*in2023was 4.5personsonaverage. *The number of total workers per billion wonof output. ―The coefficient of agricultural,forest,and fishery products(19.0 persons)wasthe highest,followed by services(6.7 persons)and then construction(5.5persons). □The workersrequirement coefficient*was8.2personsin2023. *The number of total extra workers created by an additional 1 billion won increase infinaldemand,which measures the direct and indirect impact of changes in finaldemandonemployment. ―The coefficient of services(10.0 persons)was almost twice as high asthatof manufacturedgoods(5.1 persons).
