Manufacturing

Overview

Manufacturing (Korean: 제조업; 製造業) is an industry that converts inputs such as raw materials and components into new products through physical and chemical processes. It sits between primary industries such as agriculture and mining and the service-centered tertiary industry, and is classified as a core foundational industry that determines a country's productivity, export competitiveness, and employment. In the modern economy, manufacturing is understood not merely as simple processing but as a complex value chain combining design, R&D, supply chain management, and after-sales service.

Key Details

Definition and Scope

In the Korean Standard Industrial Classification (KSIC), manufacturing is placed under Section C and subdivided into about 20 subcategories, including food products, textiles and apparel, wood and paper, petroleum and chemicals, pharmaceuticals, rubber and plastics, non-metallic minerals, primary metals, fabricated metal products, electronic components and computers, electrical equipment, machinery and equipment, motor vehicles and trailers, other transportation equipment (shipbuilding, aerospace, railway), furniture, other products, and repair of industrial equipment. Manufacturing includes not only the act of 'making' itself but also raw material procurement, quality control, packaging, and shipping, and is distinguished from construction and electricity, gas, and water supply.

Historical Development

  • First Industrial Revolution (late 18th century, Britain): Based on the steam engine and power loom, handicraft production shifted to factory-based machine industry.
  • Second Industrial Revolution (late 19th to early 20th century): Electricity, the internal combustion engine, and conveyor-belt mass production (Ford system) were established.
  • Third Industrial Revolution (late 20th century): Computers, PLCs, automation, and industrial robots were introduced, and lean production (TPS) and quality management spread.
  • Fourth Industrial Revolution (2010s–): Evolution into smart factories based on IoT sensors, cloud, big data, AI, and digital twins.

Production Methods and Value Chain

Production types are divided into make-to-order (MTO), make-to-stock (MTS), assemble-to-order (ATO), and engineer-to-order (ETO). Representative management techniques include JIT (just-in-time), kanban, Six Sigma, TPM, and lean manufacturing. The value chain runs in the order of R&D → design → procurement → processing/assembly → inspection → logistics → sales/after-sales service, and in recent years the ability to connect this entire process with data has become the core of competitiveness.

Economic Significance

Manufacturing creates a large amount of added value and has high forward and backward linkage effects (spillover effects), and serves as a channel through which technological innovation spreads to other industries. In advanced countries, its share of GDP has fallen to around 10–20%, but it remains important as a core axis of exports and productivity growth. On the other hand, it also has structural weaknesses such as energy consumption and carbon emissions, the burden of large-scale facility investment, and sensitivity to economic cycles.

Major Countries

China is the largest producer, accounting for about 30% of global manufacturing value added, followed by the United States, Japan, and Germany. Germany has formed a structure centered on precision machinery and its 'Industry 4.0' strategy, Japan on materials, components, and quality management, and Korea on an export-oriented manufacturing structure centered on semiconductors, automobiles, shipbuilding, steel, petrochemicals, and defense.

Latest Trends

  • Manufacturing AI transformation, including smart factories, digital twins, and AI vision inspection, is the biggest topic in 2024–2025.
  • Amid the U.S.-China technology hegemony competition and post-COVID-19 supply chain risks, reshoring, nearshoring, and friendshoring are spreading.
  • Industrial policies and trade regulations such as the U.S. IRA and CHIPS Act and the EU Carbon Border Adjustment Mechanism (CBAM) are reshaping production locations.
  • Under pressure for carbon neutrality, green manufacturing investments such as electric furnaces, hydrogen-reduction steelmaking, and renewable energy transition are expanding.
  • The introduction of 3D printing (additive manufacturing), collaborative robots, and autonomous mobile robots (AMRs) is increasing responsiveness to high-mix, low-volume production.
  • In response to population decline and skilled labor shortages, unmanned and automated operations and standardization of manufacturing data are accelerating.
  • Korea, amid strong performance in semiconductors, automobiles, shipbuilding, and defense, simultaneously faces the tasks of 'manufacturing AX (AI transformation)' and balanced regional development.
