What are the main two 2 reasons for the growing share of the service sector in all major economies of the world?

Major Economic Sectors

1. Primary Sector

The primary sector is composed of industries engaged in the business of gathering raw materials. It includes mining companies, lumber companies, and oil drilling companies – along with the agricultural and fishing industries.

2. Secondary Sector

The secondary sector includes all businesses involved in producing and selling goods – such as auto manufacturers, furniture stores, and clothing retailers.

3. Tertiary Sector

The tertiary sector is the service sector. It includes industries such as the financial services industry, internet technology (IT), and the healthcare and entertainment industries.

Some economists include a fourth sector – the quaternary sector in which they assign the areas of research, information technology, education, consulting, and various other elements of what has come to be known as the “knowledge-based economy.”

The knowledge-based economy is focused on utilizing information and communications (such as social media) to provide goods and services specifically tailored to the needs and wants of individual customers or clients.

An example of the knowledge-based economy in action is a retailer, such as Amazon or Walmart, sending you tailor-made ads for goods or services that your previous purchases or searches indicate that you are interested in.

Economists who do not use a fourth economic sector category assign the quaternary sector industries to the tertiary sector.

Economic Development

The tri-sector economic theory holds that the three economic sectors, in addition to delineating different areas of economic endeavor, also reflect how economies develop over time.

The most primitive economies consist primarily of economic activities related to raw materials, agricultural production, and fishing. As economies grow and develop, the manufacturing and marketing of finished goods account for the largest portion of economic activity.

Service industries are the last economic sector to experience significant growth and are the hallmark of developed nations and advanced economies.

The Primacy of the Service Sector

The fact that the service sector is designated as the tertiary sector should not be in any way taken to mean that it occupies third place in terms of economic importance.

Over the past century, the service sector has rapidly expanded. By the turn of the 21st century, it had eclipsed the manufacturing and retail goods sector as the largest sector of the economy in most developed nations.

Whereas in the early part of the 20th century, the United States became the dominant world economy, thanks to its massive manufacturing industry; by the early part of the 21st century, its worldwide economic dominance was based on its massive service sector.

In the U.S., between 1919 and 2019, the service sector grew from accounting for less than 50% of the country’s gross domestic product (GDP) to generating roughly 85% of the country’s GDP.

The explosion of the service sector has been made possible by the exponential increase in knowledge that has occurred over the past 50 to 70 years, the rapid growth of technology, and the development of instantaneous, worldwide communication through internet connections and cell phones.

Increased automation, which reduces the number of people required for manufacturing processes, is also a key element in the shift from a manufacturing-based economy to a service-based economy.

The massive expansion of government services in developed nations is another significant contributing factor to the increasing predominance of the service sector.

Examples of Service Industries

Many people do not realize the huge number of businesses and industries that combine to make up the service sector.

But if you stop and take some time to think about all the various service-related businesses, then it becomes very easy to see why the service sector is, by far, the largest sector of the economy in developed nations such as the US, the UK, Canada, Australia, Germany, and Japan.

The following are brief descriptions of just a few of the many businesses that comprise some of the major industries contained within the service sector.

1. Travel Industry

The travel industry goes way beyond just the offices of travel agents and major airlines. It also includes the rapidly growing operations of public transportation, such as subways and city buses. Uber, Lyft, and Airbnb – major businesses that didn’t even exist a mere 20 years ago – are part of the travel industry.

Additionally, the countless tourist attractions such as museums, recreation parks, national parks – such as Yellowstone and the Grand Canyon – concert halls, and art galleries, along with the tens of thousands of local tourist attractions spread throughout the country, are included in the travel industry.

Hotels, motels, and the entire hospitality industry are also considered part of the travel and tourism industry.

2. Information Technology Industry

The IT industry is composed of virtually anything and everything related to computers, information, communication technology, and software – except for the manufacturing of necessary hardware such as computers themselves.

The whole gamut of social media – from Facebook to Twitter to Instagram and YouTube – encompasses literally millions of individual businesses. Did you know that, as of 2019, more than 30 million YouTube channels were originating in the US?

Online education, one of the most rapidly growing industries worldwide, also falls under the broad umbrella of the information technology industry.

3. Media and Entertainment Industry

Technological inventions and advancements have also created a huge expansion of the media and entertainment industry. News used to be distributed by radio stations, print newspapers, and network television channels.

The rise of cable and satellite TV has given birth to an entertainment world that contains dozens of different news channels. For example, Fox, CNN, and NBC not only provide 24-hour news programs, but they even operate separate business news channels.

Online news and information websites are far too numerous to count. There are vastly more “made-for-television” movies produced every year than the number of films produced by all the major motion picture studios and production companies.

People can spend their entire day watching online entertainment provided by YouTube or Pinterest or playing video games on their Xbox or PlayStation. Among the lucrative newer occupations are those of video game and app developers, social media consultants, and graphic website designers.

The brief descriptions above, which are nowhere close to being exhaustive, give us just a small sense of how truly massive the service sector of our economy is – and we didn’t even mention the multi-billion dollar healthcare, sports, and financial services industries.

Fintech (financial technology) businesses – another economic entity that has only come into being since the turn of the century – alone are nearly a $150 billion industry as of 2018 and are expected to surpass $300 billion in market value by 2022.

Services, with their rising importance in the global economy alongside manufacturing, are becoming more vital in many countries’ economic growth.

It took centuries for the world’s economies to shift from agriculture to manufacturing, but the rise of the services sector is occurring more quickly. The world is in the midst of a radical shift, with the share of total output—world GDP—accounted for by services experiencing a sharp increase in almost all countries.1 Indeed, a few countries, such as India and Sri Lanka, have broken the historical convention by heading straight to services without developing a significant manufacturing sector at all.2 This growth in services has likely transformed not only the composition of the world’s economic production and employment, but potentially global trading patterns over the past few decades.

Services dominate in output, value added, and employment

The relationship between services growth and overall economic growth has become stronger in the past two decades as services’ average contribution to GDP and value added has increased. In 2015, services’ value added accounted for 74 percent of GDP in high-income countries, up from 69 percent in 1997. The contribution of services’ value added to GDP was higher in the United States than among its peer high-income nations. The increase in services’ share of GDP was even more prominent in low- and middle-income countries, where it jumped to 57 percent in 2015 from 48 percent in 1997 (figure 1). With services contributing more to output, the corresponding contributions of industry and agriculture to GDP declined; the share of manufacturing fell the most during this period.3

A country-wise analysis of services’ contribution to total value added yields similar findings. Except in a few major developing nations such as Indonesia, China, and India, the services sector contributed over 60 percent of total value added in 2017 in all major economies (figure 2). With the Asia Pacific Economic Cooperation (APEC) forum4 and the Association of South East Asian Nations (ASEAN)5 renewing their focus on the importance of a competitive services agenda to realize overall growth and development across their respective regions, the services sector in these economies too will likely join the 60-plus-percent club soon.

The growth of the services sector’s output has led to employment growth. In fact, for a majority of the world’s economies, the services sector is by far the biggest employer.6 In all Organisation for Economic Co-operation and Development (OECD) member countries, more than 70 percent of the employed labor force worked in the services sector in 2017; among high-income industrialized OECD member countries, except for Greece, this proportion exceeded 80 percent (figure 2).

In the United States, in 2017, value added in the services-producing industries accounted for 78.9 percent of total value added, amounting to US$13.1 trillion, and 86.3 percent of total private employment, representing 124 million employees.7 As shown in figure 3, the categories of service activities are wide-ranging, including everything from education and health care services to professional business services.*

With the rise of the services sector across economies, the world’s trade structure too has been changing.8 Services today comprise a growing proportion of nations’ trade baskets, with varying impacts on their current account balance. Considering the dollar value of exports, manufactured goods exports remain the largest category at US$11.6 trillion, but agricultural products and services have been the fastest-growing (5.3 percent and 5.1 percent per year, respectively) between 2006 and 2016 (figure 4). Manufacturing exports grew by only 3.2 percent per year over the same period. Due to lower fuel prices in the later part of the period—an average of US$43.29 per barrel in 2016 compared to US$66.05 per barrel in 2006—the dollar value of fuels and mining exports dropped between 2006 and 2016.9

The share of services exports in the world’s total goods and services exports increased from 17 percent in 1980 to more than 24 percent by 2016, while its share in world GDP increased from 3.7 percent to 6.5 percent during the same period (figure 5). A surplus in services trade is the reason that a few countries, such as Iceland, Lithuania, and New Zealand, have a current account surplus (New Zealand has a surplus in the current account net of primary income)—their services surplus is larger than their goods deficit.10 In other countries, such as the United States, the trade surplus in services helps partially offset the trade deficit in goods, even though the overall balance remains negative.11 Of course, not all countries are running a trade surplus in services. Singapore and Germany are examples of countries that have a negative trade in services balance, even as their trade in goods balance is positive.12

This transition toward trade in services may be reaching its maximum in high-income countries other than the United States, although it is continuing among emerging nations (figure 6). According to World Bank data, the globalization of services has been more significant for developing countries, where services exports are growing much faster than in developed countries; developing countries’ share in world services exports has increased from 12 percent in 1980 to 21 percent in 2016. China is a notable example—a manufacturing powerhouse that has transformed dramatically between 2005 and 2015 to move into services, which contributed over 50 percent of GDP in 2015, up from 40 percent in 2005.13

The composition of trade within the services sector has changed as well since the early 1980s.14 The share of travel and transport in services exports has come down over the past 35 years across countries in all income groups (figure 7). At the same time, high-income nations have been exporting more insurance and financial services, while low- and middle-income countries have focused more on exporting communications and computer services over time. High-income nations have continued to be the largest recipient of the world’s intellectual property (more than 98 percent), even as the marginal share of low- and middle-income countries has fallen since 1982.

The set of charts in figure 8, which gives country/area details on several major services categories, chronicles 14 years of substantial change, including the lessening of US dominance in several categories of services exports. For example, the share of IT services exports contributed by the United States fell from 45 percent in 1990 to 8 percent in 2014, with the United States now behind the Euro area, India, and Ireland in this category. China, not in the top 10 in any category in 1990, broke into the top tier of service exports in transport, travel, information technology, and the “other” category. France fell from being the top financial services exporter in 1990 to eighth place by 2014.

That services trade accounted for a quarter of total world exports on a gross basis understates the services sector’s importance to trade. In fact, when considered on a value-added basis, services trade made up 39.2 percent of world trade in 2011.15

To understand why services trade’s value-added share differs from its gross share in world trade, consider that many traded goods and services are created by combining intermediate inputs of component goods and services, some of which may be imported. As a simple example, a pharmaceutical product produced in country X is a manufactured good that may incorporate intellectual property from country Y (a service) and a plastic bottle from country Z (a good), in addition to the value added in country X itself. However, the standard international system of accounts tracks the flow of both intermediate and final goods and services each time they cross a national border, based on the characterization of the good or service at the time. Therefore, when a good or service crosses a national border for the last time, its total value is attributed to a single industry within that country’s goods or services sector, even though its “production” was a combination of domestic and imported intermediate inputs and a combination of goods and services inputs.

As shown in figure 9, the domestic content of manufactured exports is much lower than the domestic content of services exports. For example, the German value added to German manufacturing exports was 69.3 percent in 2011, while the German content of German services exports was 88.2 percent.

Increasingly, services are being delivered—that is, traded, both within borders and across borders—digitally. This trend will likely continue to increase as more people connect to the internet and trade digitally with the rest of the world. With their increasing tradability and rising importance as inputs to traded goods and services, services are poised to play an increasingly vital role in many countries’ economic growth. We do not minimize the importance of manufacturing to the overall health of the economy, but priorities should also recognize services’ essential role. A healthy services sector is no less necessary for a strong economy than a healthy manufacturing sector.
