What are Global Value Chains and why they matter for economic & regional development | LSE Research

Main Ideas and Concepts

• Value chains explain how everyday products are made

  • Social scientists use the value chain concept to describe the full process behind goods people use daily: design, production, and delivery, including the time and skills involved.
  • Example used: bicycles.

• The evolution of production and trade

  • Era 1: Trade in final goods
    • Historically, bicycle production was mostly handled within one firm and one location, with firms making the complete product themselves.
  • Era 2: Trade in intermediate goods
    • New technologies enabled fragmentation of production.
    • Instead of one firm making the whole bike, production occurs across multiple establishments, each specializing in specific components.
  • Global value chain definition
    • A global value chain covers all steps from:
      • Research, conception, and design
      • through production, sales, and aftercare
    • It spans multiple firms across different places worldwide.

• International specialization across regions

  • The bicycle example illustrates cross-country component sourcing:
    • Brakes mainly from Japan
    • Frames mainly from China and Vietnam
    • Saddles produced in Italy (as stated)

• How countries can participate and “move up” the chain

  • Countries trying to enter the bicycle industry do not need to produce the entire bike.
  • Instead, they can start by contributing a component or task that matches what they already do well locally.
  • From there, they can upgrade along the value chain—described as moving up the smile, where higher-value activities tend to be at the ends/top.

• Upgrading strategies: horizontal and vertical movement

  • Example company: Shimano
    • Began producing freewheels in Sakai City
      • Supported by a regional advantage in heavy industry.
    • Horizontal upgrading: moved into related parts such as speed changers.
    • Vertical upgrading: moved into new R&D activities.
  • Key claimed outcome: such changes can still create new jobs within the same regions.

• Policy and future challenges

  • Regions and cities planning economic development should:
    • Determine where they are in global value chains
    • Use strategies aimed at upgrading in those chains.
  • Potential unintended consequences:
    • Policymakers must ensure value is not only extracted, but also that:
      • Value is provided to regions
      • Value is diffused to local actors
  • Future context: with geopolitical fragmentation and climate-related shocks, economies need new tools and strategies to balance opportunities and threats.

Instructional / Step-Like Guidance

To enter global value chains (e.g., bicycle industry)

1. Identify a component or task you can already perform well locally.
2. Start with specialization in that part of the chain rather than producing the whole final product.
3. Use local resources and capabilities as a base for expansion into more sophisticated activities.

To upgrade within global value chains

• Horizontal upgrading: move into producing related components/parts.
• Vertical upgrading: move into higher-value activities, such as research and development.
• Align upgrading paths with regional strengths (e.g., existing industrial advantages).

For policymakers (ensuring benefits)

• Assess the region’s position in global value chains.
• Adopt policies that help ensure global value chains:
  • do not merely extract value, but also
  • generate and distribute value to local firms and actors.

For future resilience

• Develop new tools and strategies to manage:
  • geopolitical fragmentation
  • climate-related shocks
