2. Literature Review
Over the past almost 40 years, countries’ participation in GVC has been deeply studied.
Michael Porter’s fundamental work, “Competitive Advantage: Creating and Sustaining Superior Performance”, first published in 1985, can be considered as a reference point in the GVC study. According to Porter (1985) [
2,
3], the GVC ultimate goal is to gain a competitive advantage over competitors in the market.
Firstly, there is a lot of research devoted to the GVC participation indices. Koopman et al. (2010) introduced the GVC participation index, particularizing that it is necessary to differentiate between backward and forward participation [
4]. Johnson and Noguera (2012), and Stehrer et al. (2012) continued Koopman’s research and suggested the measures of GVC participation and GVC position [
5,
6]. Backward and forward GVC participation analysis, studies of the GVCs determinant and peculiarities, as well as an estimation of particular countries participation in GVCs were conducted in the research by Kowalski et al. (2015) [
7], Baldwin and Lopez-Gonzalez (2013) [
8], and Sidorova (2018) [
9]. In particular, Sidorova (2018) wrote that for successful integration of a country into the GVC, it is necessary to reconsider the priorities of state industrial and economic policy [
9].
Secondly, there are a lot of research papers concerning various factors influencing GVCs, especially economic integration and preferential trade agreements. Van der Marel (2015) has researched the variables that have an influence on GVC participation, systemizing them in three groups: structural forces and endowments (market size, GDP, GDP per capita, etc.); traditional trade and regulatory barriers (trading across borders, doing business, trade barriers, etc.); and new issue areas (FDI restrictions, innovation climate, etc.) [
10]. Van der Marel found the positive impact of GDP per capita and the negative impact of market size (population), FDI restrictions, and trading across borders on backward GVC participation [
10]. European Union integration and its GVCs particularities were studied by Amador, Cappariello, and Stehrer (2015) who found substantial heterogeneity between countries in the evolution of GVCs and made the conclusion that the high relevance of GVCs in the euro area is accompanied by their comparatively stronger resilience in the face of trade collapse [
11]. Continuing the above-mentioned research, Amador and Cabral (2016) summarized general drivers of GVC participation, such as lowering the trade and investments costs, trade and investment liberalization, regional trade blocs (integration), EU enlargement, and technological development [
12]. Another research paper for the EU-28 conducted by Kersan-Škabić (2019) showed that lack of GVC participation, GDP per capita, or GDP growth rate have a positive and significant impact on GVC participation; wages, and profit tax rates have a negative impact [
13]. According to Casella, Bolwijn, Moran, and Kanemoto (2019), the relevance of GVC data for the analysis of globalization patterns, particularly at the intersection between trade, investment, and development, is obvious [
14]. Some other research has discussed the relationship between preferential trade agreements and GVCs, in this case studies by Antras and Staiger (2012), Baldwin (2008, 2012) [
15,
16,
17] should be mentioned. They explained the development of supply-chain trade and found it very regionalized, supported by a combination of deep regional trade agreements (RTAs), bilateral investment treaties (BITs), and unilateral reforms by developing countries, mostly accomplished outside the World Trade Organization (hereinafter WTO). Continuing the study of the relationship between preferential trade agreement and participation in GVCs, Osnago, Rocha, and Ruta (2015) found that the coefficient of the interaction term between depth of preferential trade agreement and participation in GVCs is consistently positive and significant across specifications, using different variables of depth and provisions. They concluded that deep preferential trade agreements have a larger impact on GVC-intensive sectors [
18]. Moreover, Ruta (2017) introduced a trust dilemma that characterizes the relationship between preferential trade agreements and GVCs where countries can choose between four different strategies that go from a situation of no preferential trade agreement and no participation in GVCs (national production and no agreements) to GVCs and deep integration [
19]. Lastly, Ignatenko, Raei, and Mircheva (2019) found that GVC-related trade, rather than conventional trade, has a positive impact on income per capita and productivity; however, there is large heterogeneity and the gains appear more significant for upper-middle and high-income countries [
1].
Thirdly, several researches are focused on supply chain sustainability or resilience. At the international level, the standard ISO 28002:2011 “Security management systems for the supply chain—Development of resilience in the supply chain—Requirements with guidance for use” is accepted. In 2004, as a basis for the sustainability of supply chains, Lee proposed the Triple-A approach: Triple-A = Agility + Adaptability + Alignment. According to Lee (2004), the most successful, i.e., sustainable, are the companies whose supply chains have such characteristics as dynamism, adaptability, and alignment [
20] (pp. 102–112). It should be mentioned that in 2003, the sustainability of the supply chain was defined as the ability to respond to unexpected failures and restore the normal operation of the supply chain [
21] (pp. 22–30). Rice and Caniato (2003) considered that in today’s business environment, we need a supply network that has comprehensive security processes and procedures in place and is resilient enough to bounce back from any disruptions that do happen [
21] (pp. 22–30). Another approach to GBC sustainability was suggested by Ponomarov and Holcomb (2009) who described sustainability as the adaptive ability of supply chains to prepare for unexpected events, respond to failures, and recover from them, maintaining the continuity of operations at the desired level of connectivity and control over structure and functions. According to Ponomarov and Holcomb, supply chain disruptions have adverse effects on both revenue and costs. Resilient supply chains incorporate event readiness, are capable of providing an efficient response, and often are capable of recovering to their original state or even better, post the disruptive event [
22] (pp. 124–143). Day (2014) adheres to a similar interpretation, while including in it the need to predict risk and minimize its impact. A complex adaptive supply network (CASN) lens was also suggested, which is used to frame what existing literature has uncovered regarding disaster relief efforts, showing how relief organizations, their interactions, and their environmental context help determine the level of resilience that supply networks experience following disasters. This CASN characterization is leveraged to help explain why traditional supply chain management practices lead to varied results in disaster relief [
23] (pp. 1970–1988). Thus, due to Liao and Fan Ziyang (2020), supply chain visibility is crucial to understanding the impact of disruption [
24]. According to Miroudot (2020), in times of a pandemic, it may be premature to call for the end of GVCs or to conclude that shorter supply chains would be less vulnerable. Thereby, the relationship between GVCs and resilience or robustness in the supply of inputs is more complicated than it looks. Thus, policies in the future should support business efforts to build more robust and resilient supply chains, and not add to health and other dangers a policy risk built on misconceptions about GVCs [
25]. In our opinion, the concept of GVC resilience, or the strength of an economy or a regional grouping against systemic risks, introduced by Sangaraju and Bayhaqi (2020), is of particular importance. The GVC resilience is considered as the inverse value of risk: a range of factors determining the ability of an economy to respond to risks, limit their economic and social consequences, and restore the state of the value chain at the pre-crisis level [
26].
Fourthly, there are several research studies concerning the role of energy indicators in sustainability and sustainable development. The role of energy indicators for tracking sustainability in developing countries was examined Kemmler and Spreng (2007) [
27]. Furthermore, Taylor et al. (2017) particularized better energy indicators for sustainable development [
28], and Perea-Moreno and Hernandez-Escobedo (2021) conducted analysis of advances in renewable energy and energy saving systems for the sustainable city [
29]. Sustainability outlook of thermochemical-based second-generation biofuel production was presented by Meramo et al. (2021) [
30]. Two more pieces of researches should be mentioned in this case. Haddad et al. (2021) identified a framework for assessing urban energy sustainability [
31], and Aldhshan et al. (2021) discussed energy consumption and spatial assessment of renewable energy penetration and building energy efficiency [
32].
Finally, there is a lack of research on the relationship between countries’ energy indicators and their participation in GVCs. Nevertheless, several studies concerning energy sustainability and value chains are of particular interest. First of all, the Energy Trilemma Index suggested by Mastepanov and Chigarev (2020) is of great importance in assessing the sustainability of national energy policy and the development of safe, equally accessible, affordable, and environmentally sustainable energy [
33]. Another interesting study was conducted by Palekhov and Palekhova (2018) who clarified the specific features of the modern concept of energy efficiency, which is based on three core dimensions—energy security, energy equity, and environmental sustainability. This concept was considered as the basis for further development of GVCs, as an approach for assessing energy efficiency of their links, and for planning appropriate joint actions [
34]. Elemental concepts utilized in the Global Production Networks (GPNs) literature such as those used in global commodity chain, global value chain, and supply chain research were described by Van de Graaf et al. (2016). Three case studies related to energy and global production systems—solar photovoltaics, shale gas, and salmon aquaculture—were detailed [
35]. Continuing GVCs researches, Bamber, Guinn, and Gereffi (2014) made use of the global value chain framework to unpack the multiple issues and constraints facing Burundi’s electrical energy sector [
36]. A GVC analytic framework to analyze the wind energy value chain in South Africa and its impact on localization of goods and services was utilized by Morris, Robbins, Hansen, and Nygard (2021) [
37]. One more interesting model should be mentioned here. Sarkar Biswajit et al. (2021) suggested the multi-setup multi-delivery (MSMD) concept. The model’s goal is to show bioenergy’s effect to make a sustainable supply chain of biofuel and biogas [
38]. Thus, supply chain management aims to integrate environmental thinking with efficient energy consumption into supply chain management. It includes a flexible manufacturing process, more product delivery to customers, optimum energy consumption, and reduced waste. Vandana Singh et al. (2021) considered a two-echelon supply chain, particularizing a producer and supplier with two-level trade-credit policies (TLTCP) with the optimum consumption [
39]. A suitable way of smart production was proposed by Bhuniya Shaktipada et al. (2020). They concluded that selling price and energy consumption-dependent demand should be considered for producer and customer benefit [
40]. Another interesting model was proposed by Lim Byeongho et al. (2020). It is a quantitative approach using a computational general equilibrium (CGE) model to estimate the effects of the reverse GVC factors on the global economy, trade, and energy market [
41]. A robust analysis of the global supply chain and manufacturing costs for components of Organic Rankine Cycle (ORC) turboexpanders and steam turbines used in geothermal power plants undertaken by Akar et al. (2018) [
42] is of particular interest as well. Lastly, Wu et al. (2020) studied the causality between participation in GVCs and renewable energy consumption [
43].
In
Table 2 the contribution of different authors to the study of GVCs is given.
Table 2 describes the different research gap mentioned in the literature review.
From
Table 2, it is clear that research on a relationship between countries’ energy indicators and the GVC participation indices has yet not been conducted. Moreover,
Table 2 has helped us to highlight these research gaps.
3. Materials and Methods
Asia-Pacific Economic Cooperation (hereinafter APEC) member economies were used as an object of the study. APEC currently includes 21 member economies. They are as follows: Australia, Brunei Darussalam, Canada, Chile, China, Hong Kong SAR (China), Indonesia, Japan, the Republic of Korea, Malaysia, Mexico, New Zealand, Papua New Guinea, Peru, Philippines, the Russian Federation, Singapore, Chinese Taipei, Thailand, the United States of America, and Vietnam. APEC is one of the few international associations to which Taiwan has joined with the full approval of China (in our study it will be referred to as Chinese Taipei). Therefore, APEC adopted the term “member economy” instead of “member country” [
44] (pp. 110–120).
The data of the World Bank (hereinafter World Bank), the World Trade Organization (hereinafter WTO), the World Economic Forum (hereinafter WEF), the International Monetary Fund (hereinafter IMF), the United Nations (hereinafter UN), the Organization for Economic Cooperation and Development (hereinafter OECD), the International Energy Agency (hereinafter IEA), etc., were used as the information base of the research.
Data from the international database TiVA (Trade in Value-Added) were used to assess the countries’ participation in the GVCs [
45]. TiVA is a joint product of the OECD and the WTO. The first version included information on 40 countries with a low degree of detail by economic sectors. There were only 18 economic sectors in total. The latest version of TiVA–2016 covers 64 countries with details on 34 industries. TiVA is based on the OECD Inter-Country Input–Output (ICIO) model, which allows a number of important indicators characterizing the process of value-added creation to be determined, including: foreign value added in domestic final demand, domestic value added in foreign final demand, value-added share of total final demand by country and industry, value-added share of consumption by country and industry, value-added share of gross fixed capital formation by country and industry, etc. TiVA dynamic series begin in 1995; data are published with a significant time lag of up to 5 years [
9] (pp. 71–80).
In the course of the research, the methods of chronological average, economic and mathematical modeling, and econometric methods of analysis were used. The statistical time series TiVA for the eleven-year period 2005–2015 were used as an information base.
In our methodology, we develop an approach to evaluate each individual country’s GVC participation, proposed by Sidorova [
9] (pp. 71–80) and based on TiVA data for assessing countries’ backward and forward GVC participation indices and total GVC participation index. Our methodology is a continuation of the approach suggested by Baldwin and Lopez-Gonzalez [
8] (pp. 1682–1721), who conducted an analysis of supply-chain independence and assessed the contribution of natural resources in GVCs.
Research methodology is as follows.
Two following indices are traditionally used to assess the participation of countries and regions in the GVC:
The share of foreign value added in total exports, which characterizes the backward GVC participation. A high share of foreign value added in exports allows a country to import the necessary resources for the production of exported goods, components, or services [
46] (pp. 589–606);
The share of a country’s national (domestic) value added arising from its own exports (direct and indirect through the exports of other domestic industries) included in exports of other countries, i.e., the forward GVC participation. This is an indicator of the country’s value added that is not consumed directly at the export destination, but is re-exported. A high level of the GVC participation means that the country exports more intermediate goods and services used for the export of other countries [
46] (pp. 589–606).
The sum of these two indices gives the country’s GVC participation index.
Four indicators were selected to confirm the hypotheses postulated in Introduction (
Table 1):
GDP per unit of energy consumption (PPP USD per kg of oil equivalent). This indicator is the inverse of the GDP energy intensity;
Energy imports, net (% of energy use);
Fuel exports (% of merchandise exports);
Energy intensity level of primary energy (mJ/USD2011 PPP GDP).
Country’s participation in GVC is assessed based on the following indices:
Forward GVC participation index, %;
Backward GVC participation index, %.
The chronological average for each indicator and index is calculated for each particular country. The calculations were made for the eleven-year period 2005–2015. As an information base, the statistical time series TiVA, OECD/IEA are used.
Then, taking into account the obtained values of the chronological averages within each indicator, the APEC member economies are divided into two groups according to the following criteria:
In terms of GDP per unit of energy consumption, the value of 10 PPP USD per kg of oil equivalent was chosen. Economies with the value of GDP per unit of energy consumption more than 10 PPP USD per kg of oil equivalent are classified as “the economies with higher GDP per unit of energy consumption”. Economies with the value of GDP per unit of energy consumption less than 10 PPP USD per kg of oil equivalent are classified as “the economies with lower GDP per unit of energy consumption”.
According to net energy imports, a positive value of the indicator was chosen as a criterion. In this case, the country is an energy importer. On the other side, the country is an energy exporter if a negative value of net energy imports is observed.
According to fuel exports, the value of 10% of fuel exports in merchandise exports was chosen as a criterion. Countries for which the share of fuel exports in total merchandise exports exceeds 10% are classified as fuel exporting countries. Countries for which the share of fuel exports in total merchandise exports is less than 10% are classified in the group with a low share of fuel exports in total merchandise exports.
According to the energy intensity level of primary energy, the value of 5 MJ per USD2011 PPP GDP was chosen as a criterion. The level of energy intensity of primary energy shows the ratio between energy supply and gross domestic product. This ratio is measured by purchasing power parity. Energy intensity shows how much energy is required to produce one unit of economic output. The lower this ratio, the less energy is used to produce one unit of production. Accordingly, such production or economy is less energy intensive. Countries for which the energy intensity level of primary energy is less than 5 MJ per USD2011 PPP GDP are classified in the group of countries with low energy intensity. Countries for which the energy intensity level of primary energy is higher than 5 MJ per USD2011 PPP GDP are classified in the group of countries with high energy intensity.
4. Results and Discussion
4.1. Analyzing APEC Member Economies Positions in the World Energy Trilemma Index
First, it seems important to analyze the positions of the APEC member economies in the ranking on the World Energy Trilemma Index for 2020–2021 (
Table 3). There are 127 countries represented in the 2021 ranking. Data for 19 APEC member economies are available (with the exception of Chinese Taipei and Papua New Guinea).
Since 2010, the World Energy Trilemma Index has been providing an independent and objective assessment of a country’s energy policy and its effectiveness, using proven global and country-specific data to assess governance on three main parameters: energy security, energy equity, and environmental sustainability.
Countries develop energy policies depending on their internal conditions due to various natural resources, geographical location, and socio-economic systems. This divergence of different systems and contexts means that there is no unified path for a successful energy transition. Each country needs to determine its own best way of energy policy instead, taking into account the national situation and priorities. This means that a direct comparison of countries’ rankings and scores may be less informative, but at the same time it can help start a conversation. Countries can and should learn from each other, finding out which policies work and why such policies can be successful in some contexts and not in others. The Global Energy Trilemma Index can help countries and stakeholders in the energy sector to identify in a continuous dialogue which areas of energy policy need to be improved. Studying the examples of other countries can help determine the most suitable options.
When calculating the Global Energy Trilemma Index, 31 indicators of the national energy policy efficiency are taken into account. These indicators are grouped in three dimensions [
47,
48]:
Energy security assesses a country’s ability to meet current and future energy demand, and withstand and recover quickly from systemic shocks with minimal supply disruptions. This parameter takes into account the efficiency of internal and external energy sources management, as well as the reliability and sustainability of the energy infrastructure [
33].
Energy equality makes it possible to assess a country’s ability to provide universal access to reliable, fairly priced, and abundant energy resources for domestic and commercial use. This parameter takes into account basic access to electricity and environmentally friendly fuels and technologies for cooking, access to energy consumption that ensure prosperity, as well as the availability of electricity, gas, and fuel [
33].
Environmental sustainability of energy systems shows the possible transition of the country’s energy system to reduce and prevent potential environmental damage and the consequences of climate change. This parameter takes into account the productivity and efficiency of energy production, transmission and distribution, decarbonization, and atmospheric pollution [
33].
In the 2021 ranking, 127 countries were ranked in 101 positions. In the 2020 ranking, 128 countries were represented, occupying 108 positions. Among the APEC member economies, Canada (6), the USA (9), and New Zealand (9) entered the top ten countries in terms of energy policy efficiency in 2021 (
Figure 1). China (51), Thailand (53), Indonesia (58), and Vietnam (61) are in the second half of the ranking. Twelve APEC member economies improved their positions in the ranking over the year: Brunei Darussalam rose by 13 positions, Thailand—by 11 positions, Malaysia and Japan—by 8, Australia—by 7, the Philippines and Singapore—by 6, China and Vietnam—by 4, Mexico—by 2, Russia and New Zealand—by 1. The positions of Canada (6), the USA (9) and Chile (37) remained unchanged. The Republic of Korea, Hong Kong SAR (China), Peru, and Indonesia dropped slightly down in the ranking.
Canada has been the leader of the ranking according to “Energy Security” for several years. This is facilitated not only by significant natural resources, but also by the consistent efforts of the Canada’s Government of to diversify its energy system. The United States is also in the top 10 countries, in the seventh position.
According to “Energy Equality”, the USA became the best of the APEC member economies in 2021 (eighth position). All countries that achieved greater energy equality are implementing progressive energy strategies aimed at encouraging investment in sustainable energy and electricity infrastructure and increasing diversification of energy sources as countries try to balance changing demand with the availability of energy resources. The countries leading in the direction of energy equality are developed countries, as well as the countries of the Arabian Peninsula, OPEC members, with well-established, stable, and complex energy systems and infrastructure. For developing countries, the challenge is to improve access to and affordability of energy to meet the growing demand for energy to support fast-growing economies.
According to “Environmental Sustainability”, none of the APEC member economies entered the top ten. Despite ongoing efforts to decarbonize energy production, ensuring continued progress in environmental sustainability remains a challenge. Countries that are improving their environmental sustainability are switching to renewable energy sources, such as wind and solar energy. APEC member economies, most of which are developing ones, are at different stages of industrialization. They continue to increase the use of mineral raw materials, fuels, and other non-renewable natural resources. Thus, the energy intensity of these economies continues to grow.
4.2. Indicators of APEC Member Economies’ Participation in Global Value Chains
To assess the participation of APEC member economies in the GVCs, the TiVA dynamic series for 10 years (2005–2015) will be used [
45].
The following APEC member economies are in the lead in terms of the backward GVC participation: Vietnam, Singapore, Malaysia, Mexico, Thailand, South Korea, and Chinese Taipei. In these countries, during the time period under review, the share of foreign value added in total exports exceeded 30%. It is very significant that the countries of Southeast Asia are mainly represented among the leaders (
Table 4). Thus, it can be concluded that now the GVCs begin in Asian countries and stretch to European states. However, in the future, this trend may change, and the GVCs finish in Asian countries [
49] (pp. 263–272).
Concerning the forward GVC participation, over a ten-year period, the value of this index exceeded 30% on average in the five APEC member countries only. These are Brunei Darussalam, Russia, Peru, Chile, and Australia (
Table 5).
Figure 2 shows the dynamics of APEC’s cumulative participation in the GVCs. The consequences of the global financial crisis of 2009 for the GVCs in the APEC region can be seen in
Figure 2 as well.
4.3. Determining the Relationships between Countries’ Energy Indicators and the GVC Participation Indices

Hypothesis 6 (H6).Countries with higher energy intensity level of primary energy have higher backward GVC participation than countries with lower energy intensity.
Comparing the results obtained with the existing data, it should be noted that our conclusions are confirmed by similar data by Larionov and Andryushchenko (2016) [
51] for South Korea, as well as Listopadov and Semenov (2019) [
52] for the African region. Research conducted by Lim et al. (2021) [
41] who used a computational general equilibrium (CGE) model to estimate the effects of the reverse GVC factors on the global economy, trade, and energy market for ASEAN, paying particular attention to the influence of energy source, should be mentioned as well.
