1. Introduction
Gerschenkron [
1] put forward the theory of backwardness advantage that due to the diversity and selectivity of institutional arrangements, underdeveloped countries can be at a relatively high starting point from the very beginning by imitating technologies from developed countries, introducing equipment and funds, and drawing lessons from successful experiences. Therefore, underdeveloped countries will achieve faster economic growth driven by a strong desire for industrialization. Related to this, Abramovitz [
2] proposed the “catch-up hypothesis”, and Brezis and Krugman [
3] proposed the “leapfrog model”. In addition, based on Watson’s “curse to the late comer”, Yang [
4] proposed the backwardness disadvantage of developing countries. This triggered a controversy regarding the two theories of backwardness advantage and backwardness disadvantage in China in the early 21st century, but it also made the theory of backwardness advantage receive widespread attention in China. Generally speaking, there is more literature supporting the theory of backwardness advantage. Guo [
5] published a paper in Guangming Daily to point out that China will achieve economic development by leaps and bounds by leveraging its backwardness advantages. The theory of backwardness advantage has gradually become one of the policy bases for guiding China’s economic growth. In the context of increasing environmental pollution in the world, many developing countries, including China, no longer regard economic growth as the only goal but pay more attention to green development. Therefore, this paper proposes that more attention should be paid to whether there is a backwardness advantage in green and sustainable development.
In recent years, the economy has grown fast in China, but regional development is extremely uneven. Compared with the developed eastern regions (hereinafter referred to as E-region), the central and western regions (hereinafter referred to as CW-regions) are considered to be the “catch-up” economy. At present, there is a large gap of the GDP and green GDP between the central and western regions and the eastern region in China. In 1995, the per capita GDP of the eastern, central, and western regions (1995 as the base year) grew on average by 8409.64, 3701.55, and 3197.10 RMB Yuan, respectively. By 2017, they reached 58,091.94, 30,825.91, and 26,345.55 RMB Yuan, respectively. The absolute gap has been widening. However, the mean growth rates of per capita GDP in the three regions were 9.36%, 10.16%, and 9.99%, respectively. The per capita GDP growth rates of the CW-regions were 0.8% and 0.63% faster than that of the E-region, that is, the CW-regions have achieved relatively faster development. It is generally believed that green technology is more difficult to develop [
6], so green development in the CW-regions may be difficult. However, we calculated the green GDP of the three regions (see
Section 2 for specific methods) and found that although the absolute gap between the green GDP of the CW-regions and the E-region is relatively large, the mean growth rate of the per capita green GDP in the CW-regions is significantly higher than the E-region. In 1995, the per capita green GDP of the three regions (1995 as the base year) were 8147.39, 3,492.00, and 2968.95 RMB Yuan, respectively, and by 2017 they were 56,545.22, 29,475.74, and 24,628.81 RMB Yuan, respectively. The per capita green GDP in the three regions grew on average by 9.37%, 10.22%, and 10.04%, respectively. The per capita GDP growth rates in the CW-regions were 0.85% and 0.67% faster than those in the E-region, which shows that the per capita green GDP of the CW-regions is catching up with the E-region at a significantly faster rate than the per capita GDP. Previous research has focused more on exploring the backwardness advantage of the traditional economy while ignoring the backwardness advantage of green GDP. However, the above data shows that the CW-regions are more likely to have a backwardness advantage of green development.
We found that the relative gaps between the CW-regions and the E-region in terms of financial capital, labor employment, and technological progress rates are all widening (see
Appendix A for details). However, China has implemented preferential education policies in the CW-regions, which has enabled faster development of human capital in these regions. In recent years, human capital has accumulated rapidly in China. By 2017, the total enrollment of higher education has been close to thirty-seven million, accounting for more than fifth part of the total scale of higher education in the world. In terms of different regions, the average growth rates of education expenditure per student in the CW-regions from 1995 to 2017 were 12.42% and 13.53%, respectively, which was higher than the 12.05% in the E-region, and the average growth rates of the population with at least higher education accounted for the population aged 6 and over were 14.01% and 11.35%, respectively, which are also significantly higher than 10.50% in the E-region. If the level of education represents the level of human capital, the absolute gap in the human capital level between the three regions will continue to narrow. From a dynamic perspective, due to the faster increasing rate of human capital level in the CW-regions, human capital in these regions has gradually become a new comparative advantage (i.e., a smaller absolute disadvantage).
Our earlier research [
6] proposed that the relatively faster accumulation of human capital will prompt a country to choose the direction of green technological progress (hereinafter referred to as GTP) based on Acemoglu [
7], and later research [
8] using the spatial Dubin model proved that human capital level is beneficial to the GTP in China. Referring to Chung et al. [
9], Jing and Zhang [
10], and Ma et al. [
6], the authors calculated the rate of GTP in the three regions in China (see
Section 2 for specific methods) and found that from 1995 to 2017, the average rate of GTP in the E-region was ahead of the CW-regions, less than the leading rate of average technological progress at 6.07% and 7.18%, respectively. This indicates that the CW-regions may indeed have developed more GTP. Based upon this, this study puts forward that the comparative advantages of human capital in the CW-regions may prompt these regions to choose GTP more, which may be the reason why the green GDP of the CW-regions has developed faster.
Sustainable development strategy and digital economy strategy widely implemented in the CW-regions may support the above statement. Sichuan Province focuses on the development of the digital economy and now Chengdu, the capital of Sichuan Province, has become a major digital economy center in China, with an output value of 2 trillion RMB Yuan in the digital economy in 2020. Guizhou Province focuses on the development of the big data industry and has gradually grown to a data center in China. The electronic information industry vigorously developed in Chongqing has become the main driving force for local economic growth. Provinces of Hubei, Hunan, Henan, Anhui, Jiangxi, Guangxi, Yunnan, and Shaanxi also take the digital economy and green manufacturing as their economic development priorities, and the output value of digital economy in provinces of Hubei, Hunan, Henan, and Anhui exceeds 1 trillion RMB Yuan. The digital economy of Chongqing, Hubei, Guangxi, Sichuan, Jiangxi, and Guizhou, etc., accounted for more than 30% of GDP. As these green industries have stronger competitiveness and bring higher profits, the CW-regions may have gained a backwardness advantage in green development.
The following literatures provide the basis for this paper, although it does not directly involve the backwardness advantage of green development.
Current research generally believes that technological progress is the key factor for underdeveloped countries and regions to gain a backwardness advantage [
1,
11,
12]. Gerschenkron [
1] believes that underdeveloped countries will benefit from technological and economic imitation, and the higher their degree of backwardness, the faster their growth rate and convergence with developed countries. Research demonstrated that underdeveloped countries have achieved faster economic growth in the context of international technology spillovers [
2,
11,
13]. Lin and Zhang [
14] proposed that underdeveloped countries could achieve technological catch-up and endogenous growth by leveraging their backwardness advantages. Landesmann and Stehrer [
15] believe that the comparative advantages of underdeveloped economies can be increasingly shifted to medium and high-tech sectors to achieve rapid growth. Lin [
12] believes that China has a backwardness advantage in pursuing technological innovation and structural transformation. Utku-İsmihan [
16] shows that communication and information technology play an important role in the economic growth in the underdeveloped regions of Middle East, etc., and there exists economic convergence among countries in these regions. Vu and Asongu [
17] discussed the backwardness advantage of developing countries in the information era and found that compared with the average developed countries, developing countries have gained more benefits from Internet applications. Gosens et al. [
18] showed that the formative nature of the Solar Power sector resulted in turbulent development of the technological, market, and institutional dimensions, making it more difficult for early leaders to retain leadership and therefore easier for latecomer firms or countries to catch up. Chen et al. [
19] proposed to promote market-oriented construction and improve the level of economic organization in the western region of China, which can also promote economic catch-up in these regions.
However, some researchers have also realized that achieving backwardness advantage through technological progress is not easy. Fagerberg [
20] believes that the potential for “catching up” (imitation) exists, but it is not easy to catch up through technology. It requires underdeveloped countries to have strong social capabilities to mobilize the essential resources. Forbes and Wield [
21] believe that when the follower country acquires and uses existing technology, the leading country has moved towards a new technological frontier. Harada [
22] proposed that backwardness advantage might circulate in low-tech sectors, so it was difficult to obtain backwardness advantage. Zabala-Iturriagagoitia et al. [
23] believe that innovation activities do not necessarily imply technological improvements, and innovation activities do not prompt follower and lagging countries to catch up with more advanced ones. In addition, some researchers have shown that backwardness advantages in certain industries may be difficult to achieve. Rho et al. [
24] explained the reasons for limited catch-up first in terms of the characteristics of the technology/knowledge regime of the industry where innovations are frequent and technologies are highly cumulative, which put a latecomer in a disadvantageous position. Minaee et al. [
25] found that the sectoral environment of Iran’s automobile industry was characterized by ineffective technology transfer, diverse technological areas, high tacit knowledge, etc., which contributes to the lackluster performance of catching-up by the domestic firm.
The impact of green technologies (including energy-related technologies and new energy technologies) on green development has also attracted the attention of researchers. Most research holds that green technologies are an important means of energy-saving and emission-reduction. Scholars believe that energy technology progress is beneficial to energy saving and carbon emission reduction [
26,
27]. The International Energy Agency [
28] proposed that among various approaches to mitigating climate change, green technologies are expected to become the dominant factors, which theoretically contribute to the goal of reducing more than 60% CO
2. However, in different nations and areas, the influence of green technological innovation varies due to the specific conditions of R&D and promotion for green technologies [
29]. Literature has successively concluded that technological advancement in energy and environment fields could reduce the CO
2 emissions [
30,
31,
32,
33]. Researchers proposed that green technology innovation has become an important means of reducing CO
2 emissions globally [
34,
35,
36]. Gu et al. [
37] believe that patents on renewable energy technologies and patents on energy saving and emission reduction technologies will reduce carbon emissions. Paramati et al. [
38] adopted robust panel estimation technology, taking the annual data of 25 OECD countries as the sample, and deduced that green technology reduced carbon emissions.
Although some other studies also acknowledge the role of GTP in reducing carbon emissions, they believe that under certain conditions, it may not be able to reduce carbon emissions. Researchers found that patents of energy technology were not significant to CO
2 emissions reduction in China, and the energy patents using free carbon technology only beneficial to CO
2 emissions reduction in eastern China [
39]. Braungardt et al. [
40] believe that although green innovation is regarded as a basic element of a green growth strategy, its influence on climate has been debated for a long time because of the rebound effects. Weina et al. [
35] revealed that for Italy, green innovation has improved environmental productivity, but it has failed to play an important role in reducing CO
2 emissions. Su and Moaniba [
36] believe that although climate-related technologies are theoretically beneficial to coping with climate change, the empirical evidence is insufficient. Popp [
41] pointed out that the use of green technologies often requires initial costs, which makes it impossible for poor economies to use advanced technologies of emission reduction and achieve environmental goals. Acemoglu et al. [
42] believe that the impact of green technology innovation on carbon emissions may be uncertain due to different reasons. Du et al. [
43] took 71 economies as the sample and found that green technological innovation did not have significant emission reduction effects for economies with a lower income than the threshold, but for economies with higher income than the threshold, the emissions reduction effect becomes important.
The above research shows that although there is controversy, it is generally believed that technological progress is the key factor for developing countries to achieve backwardness advantages and that green technologies are of great significance to environmental protection and green development. There is no relevant study at present on the backwardness advantage of green development in developing countries. However, the above two types of research provide the idea for this paper, that is, the GTP may bring about the backwardness advantage of green development in developing countries. This paper takes the CW-regions of China as catch-up economies and explores the possibility of backwardness advantage of green development in these regions. This is a new work. It will provide a policy basis for the further development of the green economy in China’s CW-regions, and it will also be a reference for some countries with obvious regional economic imbalances and severe environmental conditions like China.
Section 2 in this paper analyzes the mechanism of GTP on the backwardness advantage of green development and puts forward the measurement model and test method.
Section 3 takes empirical research to get the results and discussion.
Section 4 gives policy recommendations based on the research conclusions.
4. Conclusions
The provinces in the CW-regions in China are relatively underdeveloped and have a strong desire for economic development, but they have also recognized their more fragile ecological environment and thus put forward green development strategies. This paper proposes that the CW-regions in China have the backwardness advantage of green development, which is of great significance for these regions to achieve the dual goals of economic catch-up and environmental protection. The conclusions form a useful supplement to the theory of sustainable development and the theory of backwardness advantage have important theoretical significance for solving the contradiction between economic catch-up and environmental pollution in underdeveloped regions and have important practical significance for the current economic reform of China, as well as important significance for the economic transformation and sustainable development in other developing countries. This paper finds that the CW-regions have comparative advantages in human capital, and the gap in GTP with the E-region is significantly lower than the gap in technological progress. This paper proposes that the comparative advantages of human capital in the CW-regions have prompted these regions to choose GTP more, and the choice of the direction of GTP has enabled these regions to obtain the backwardness advantage of green development. Through the sys-GMM estimation, the panel data of 29 provinces, as well as regional panel data in the mainland of China from 1995 to 2017, were used for empirical research. The results show the following:
Human capital has a positive effect on GTP, and the CW-regions choose GTP based more on the comparative advantages of human capital. Therefore, to promote GTP, the government should vigorously develop education to increase the level of human capital. As underdeveloped regions, the CW-regions should not only develop the economy but also protect the environment and develop education more firmly. The CW-regions should develop more knowledge-intensive industries, provide sufficient chances for talent employment and entrepreneurship, and avoid the phenomenon of high consumption of talents.
The CW-regions gain greater green GDP growth from the GTP. That is to say, choosing the direction of GTP in the CW-regions has enabled these regions to obtain the backwardness advantage of green development. To achieve the coordination of economic catch-up and environmental protection through GTP, the CW-regions could increase the support policies for green R&D and green industries, avoid simply accepting excess industrial transfers from the E-region, and promote the transformation of lucid waters and lush mountains to invaluable assets.
In summary, the theoretical contribution of this paper is that it proved for the first time that there is a backwardness advantage of green development in the CW-regions of China. At the practical level, first, it provides theoretical support for the CW-regions of China to implement policies for green and sustainable development more proactively, so that these regions will pay more attention to education, and be able to avoid high-polluting, low-value-added industries when they are faced with international and eastern industrial transfers. Second, it provides policy reference for other countries with obvious regional economic imbalances like China, including India, Brazil, Indonesia, etc. These countries could implement fairer education policies between regions, as well as proactive environmental and economic policies.
