Case Study: Sector Shift in the UK

  • The UK is in the post-industrial stage of the Clark-Fisher model

  • It was the first country to experience the Industrial Revolution

  • In the 1800s jobs in primary economic activities were rapidly declining reaching 15% in 1900

  • In 1900 most people (over 60%) worked in secondary economic activities and tertiary economic activities were also steadily increasing

  • In the 1950s tertiary economic activities overtook secondary economic activities as the main employment sector

  • In 2021 over 70% of people in the UK are employed in tertiary economic activities

  • These changes have both positive and negative impacts

Positive Impacts

  • Deindustrialisation has led to improvements in the environment and decreased levels of pollution

  • The UK has developed expertise in secondary and tertiary economic activities which are in demand around the world

  • London is the second most important financial centre in the world after New York

Negative Impacts

  • Deindustrialisation led to high numbers of job losses particularly in the north of the UK

  • Job losses in secondary industries led to large areas of deprivation, especially in inner cities such as Liverpool and Leeds

  • Increasing numbers of transnational corporations (TNCs) have moved their factories and offices to emerging and developing countries

Case Study: Sector Shift in China

  • China is in the industrial stage of the Clark-Fisher model

  • In 1950 over 80% of the population were employed in primary economic activities - mainly agriculture

  • In 1978 China opened up to trade with the rest of the world and invested heavily in manufacturing

  • By 2005 primary economic sector employment had dropped below 50% and most people were employed in secondary and tertiary economic activities

  • In 2020 tertiary economic activity employment was increasingly important

Positive Impacts

  • Improved incomes and higher standard of living

  • More investment in education and health services

  • Increased investment by transnational corporations (TNCs)

  • Investment in roads, airports, ports and other infrastructure

Negative Impacts

  • Increasing gap between regions as some area's economies grow more rapidly

  • Increased gap between rich and poor, particularly in the gap between wealthier urban residents and poorer rural residents

  • Air, water and noise pollution all increased 

  • Increased reliance on fossil fuels to supply energy which makes China one of the world's largest COemitters

Case Study: Sector Shift in Kenya

  • Kenya is in the pre-industrial stage of the Clark-Fisher model

  • Over 50% of the population are currently employed in agriculture, this has decreased from over 60% in 2010

  • There is very little secondary economic activity due to a lack of resources and infrastructure

  • Tertiary economic activities have rapidly increased  - much of this is related to tourism

Positive Impacts

  • Improved incomes and higher standard of living

  • More investment in education and health

  • Increased investment by transnational corporations (TNCs)

  • Investment in roads, airports, ports and other infrastructure

Negative Impacts

  • Increased rural-urban migration which leads to the development of informal settlements

  • Increased gap between rich and poor, particularly in gap between wealthier urban residents and poorer rural residents

  • Much of the profits from commercial farming and tourism go to TNCs rather than local people

  • Jobs in the tertiary economic sector are often low-paid jobs in tourism

  • Increased tourism can have negative impacts on the environment and animal habitats

Worked Example

Proportion of Indonesia's GDP by Economic Sector 2020

Suggest one factor which has influenced the proportions of Indonesia's GDP

(2 Marks)

  • Answer:

  • Tertiary is the largest sector (1) because they have a well-educated labour force (1)

  • 27% of manufacturing (secondary) is the highest (1) because Indonesia is developing its manufacturing economy as part of its industrialisation (1)

  • Globalisation has allowed the country to receive more foreign investment (1) causing the growth of the tertiary and quaternary sectors (1)

  • Tertiary is the largest sector (1) due to the growth of air travel and increase in tourism (1)
