1. Introduction
The Belt and Road Initiative (BRI) proposed by China is a large socioeconomic and geographic project across countries and continents, which aims to explore the possibility of connecting China to different parts of the world, in order to promote trade and communication, and exchanges of experiences of development [
1]. Given the large magnitude of cooperation that is required, and the complex situations in various economic and cultural contexts, the international community has mixed views about this initiative [
2]. As a major commitment of the initiative, investment and trade are predicted to attract ample attention [
3] , which may create the potential for regional cooperation and development, especially in parts that were relatively forgotten in the previous round of economic globalization, such as central Asia. Also, the BRI is a way for China to sustain its economic growth, by exploring new forms of international economic cooperation with new partners, bringing with it new opportunities for relatively less developed regions; for instance, western China [
4]. Aiming for sustainable development across regions, the win–win cooperation narrowed the gap among neighboring countries and achieved mutual development. However, there are few studies that have examined the (potential) impacts of the BRI on regional economic development.
With the progress of BRI, the external economic environment changes in a region. Policy design and research capture this, primarily by considering economic openness, trade, or the degree of foreign investment. For instance, Song, Che, and Yang (2018) [
5] examine the topological relationship between the BRI and global trade networks and the key actors in these networks. Z. Liu, Wang, Sonn, and Chen (2018) examine the structure and changes in trade relations networks with the development of the BRI [
6]. Kang, Peng, Zhu, and Pan (2018) investigate the influence of the BRI on China’s outward foreign direct investment [
7]. These investigations show the external economic environment of a region under transformation. However, limited knowledge has been generated about the changes in the key development indicators (such as labor) within the region undergoing such transformation [
8], which may contribute to a deeper understanding of the regional impacts and equip regional policy makers to actively participate in and enjoy the benefits of the BRI.
In view of this, this study aimed to investigate the impact of the changes in foreign trade on the economic development of western China, following the promotion of the BRI. The purpose was to provide a stylized analytical framework that was related to the influence of the BRI on regional economic development. Since the BRI is still in its “infancy,” this study constructed a VAR (Vector Autoregressive Model) model with data from the past 20 years, to establish a general relationship between foreign trade and labor size in the western regions. The international trade also contributes to the long-term sustainability of employment and wages in the labor market, and it changes the skewed labor distribution among regions (FDI has mainly flowed to eastern coastal China during the last 40 years; this initiative could change the situation to western China’s advantage) [
9]. Next, a trend extrapolation method was applied to measure the impacts of foreign trade on employment structure. On the basis of the aforementioned analyses, the economic competitiveness of each province was evaluated, to further demonstrate the actual benefits that western provinces and regions receive, following the implementation of the BRI. In summary, this paper will assist in understanding the regional economies from the dynamic perspective of the labor market, provide an innovative perspective in policy evaluation, and set up a quantitative observation method for analyzing the impacts of the BRI on the western region, as well as on other areas. Although lacking directly related data and reference cases, we hope to provide useful recommendations for potential impacts, by envisioning the potential impacts that are based on the analysis of the workforce, and to advise on the future direction of the BRI.
5. Changes in the Labor Force of Western China with the Implementation of the BRI
5.1. The Long-Running Equilibrium between the Quantity of Labor, and Import and Export
According to the cointegration analysis, both import and export trade have a positive pull-effect on local employment. The contribution of the export volume on employment growth is greater than that of the import volume. Following the positive correlation between the import and export trade and labor force, this study further evaluated the trends of future impacts.
An impulse–response function was used for analysis.
Figure 7a shows the response of employment to the increase in export volume. The increase in a unit export volume in the current period was found to lead to a significant increase in the number of employed people in the next 10 periods. The growth in export led to the expansion of foreign demand, with a corresponding increase in the demand for labor. With the establishment of emerging trade and industrial bases in regions such as Xinjiang and Beibu Gulf economic zone, the “opening toward the west” has been continuously reinforced. Now, the border areas have become an important gateway for communication between China and trading countries, leading to a growth in exports in the corresponding areas. The growth in export has led to the expansion of foreign demand, with a corresponding increase in the demand for labor. This expansion led to a shortage of labor in the local market; as a result, wages rose and attracted an inflow of labor. In addition, from the perspective of the labor structure, the enhancement of trade cooperation between neighboring countries provided opportunities for the integration and upgrading of industries, which attracted an inflow of high-quality labor.
Figure 7b shows that an increase in unit import volume leads to an increase in the number of people employed in the following periods. This growth is sluggish and small, which represents two contradicting effects. On the one hand, the impact of imports on industrial distribution led to a fiercer business competition, which stimulated innovation and facilitated employment. Also, countries developed production according to their comparative advantages, reducing the costs of production and enhancing the international competitiveness of the industry. Imports of primary raw materials, such as petroleum and iron ore, supplemented domestic supply cutting down costs and stimulating competitiveness, which directly created more jobs in the corresponding fields. On the other hand, an increase in import may cut off employment. The main reason for this is that the growth of imports tends to dominate in the share of the domestic market, which is particularly harmful for emerging industries. Therefore, the negative impact partially offsets the positive effects, and imports have a weaker effect on the labor market. Foreign trade lowers the long-run wage in the import-competing sector, which increases the gap between the import sector and the export sector, and it limits the incentives for labor to flow in. This may also be one reason for the contribution of imports to labor attraction being lower than the export change [
39].
In general, the cumulative response to imports and exports was a significant increase in the number of people employed in the western region over the next 10 periods. It further revealed that the import and export trade volume in the western regions create a large number of employment opportunities, and have a continuous impact on future employment trends.
5.2. Trends of Labor Structural Changes
As is already known, trade is closely linked to industrial structure, by affecting the market demand and producing optimization effects. With the deeper opening of the western China market, improvements in trade affected the composition of industries by them developing comparative advantages to gain maximum profits. As a result, local manufacturing and services developed rapidly as well. Also, the BRI is expected to improve the local social environment and education level, to create favorable conditions for the region, to change the persistent outflow of labor and to attract more inflow. Therefore, the industrial development requirements and the supply–demand gap of labor have led to a shift of labor toward these industries. According to the findings of the SSA, the total industry growth rate in western China was greater than the national rate, and the comparative advantage (DS Share) in manufacturing and services was prominent. Also, the findings from DIS reveal that the western provinces are facing great labor demand in both manufacturing, as well as services. These results indicate that both these industries in the western regions have noticeable comparative advantages in manufacturing and services, which are growing fast; we can foresee a greater labor demand in the future, thus facing a greater deviation degree and generating a greater probability for labor inflow.
Take Guangxi as an example. From 2011 to 2015, the foreign trade in Guangxi has grown rapidly to 51090.5 million dollars, which accounts for 20.3% of the whole provincial GDP. Major exports include manufacturing products like fabric and porcelain, and agricultural products like seawater products. Major imports include crude oil, machine tools, paper pulp, as well as electrical products. In the meanwhile, the DS share has also increased to 9.15% in manufacturing, compared with −10.64% in agriculture and −9.67% in services. Following the leading role of manufacturing, the DIS results in Shanxi have also shown great labor demand in this industry. The DIS in manufacturing reached 152.48 in 2015, compared with 70.34 in 2011, which is consistent with the improving comparative advantage shown. Combining the DS and DIS results of Shanxi Province, we may say that over a relatively long period, there will be a huge demand in manufacturing labor. This demand change will eventually attract more inflow of labor. As shown in the data, in 2015, labor in manufacturing increased to 5130 thousand, which is 72.3% greater than that of 2011.
At the regional level, although the overall development of manufacturing appeared to be vigorous, its disadvantages were also highlighted. By comparing the growth rate from 2011 to 2013, and from 2013 to 2015, a major part of the negative growth in PS originated from manufacturing. There were problems of large volume, low profit margins, and unbalanced industrial structure. However, the western region and the country as a whole underwent a stage of industrial structure upgrades at around 2013, when the PS showed significant negative growth in manufacturing, while that of the services increased rapidly. The negative growth brought about by the industrial structure at present is mostly attributed to the adjustment of industries nationwide. Since the eastern province plays a key role in transferring manufacturing to the western region, and accepts high-profit services, in the future, it can be predicted that manufacturing in western China will definitely show significant development. Also, from 2013 to 2015, the increase in DS of manufacturing was −2.01%, indicating that its comparative advantage in the region has decreased substantially, and that services have begun to play an increasingly important role. The western region will finally see an upgrade of industrial structure from manufacturing to services.
Therefore, although the overall industrial growth of western China in 2015 was lower than that in 2013, the negative growth was mainly due to the transformations in the industrial structure. The growth of services and the decline of manufacturing are expected to change the overall industrial structure of the western regions, and eventually push the region into a stage of rapid development.
5.3. Varying Trends among the Regions in Western China
By analyzing the interception of provincial data over the past five years using SSA, it is seen that in most provinces, for example Ningxia and Shanxi, there is an obvious comparative advantage in manufacturing over the other two. This advantage is growing too. Several relatively more developed provinces have shown a structural change. In Sichuan and Chongqing, services grew faster than manufacturing and contributed most to their economic growth. From 2011 to 2015, the deviation degree of the western provinces and cities remained consistent with the overall level of the region, with manufacturing having the strongest attraction to labor inflow.
Comparing both the DIS and SSA methods, agriculture has seen negative growth in most provinces, and labor has seen an outflow. In most provinces, manufacturing, with its great advantage over that at the national level, is the one with the most demand for labor inflow. In Ningxia, Yunnan, Xizang, Guangxi, and Shanxi Province, with a relatively high DS share over western provinces, the deviation degree in manufacturing is relatively larger than that in other provinces. In services, provinces such as Sichuan, Qinghai, and Chongqing show a great advantage over the others, and the deviation degree shows the fastest yearly increase. Combining these two, we predict there will be constant labor flows into manufacturing, as well as services, since the maximum jobs are in these sectors in these provinces.
However, the situation is not the same in all provinces. In Guizhou, agriculture has the biggest advantage, although the deviation degrees are still high in manufacturing and services, which calls for labor inflows; in Neimeng, the development of all the three primary industries are below the national level; in Xinjiang, there is a huge advantage in services, while the deviation degrees are negative across the three industries, and there is labor outflow in manufacturing and services. It can be seen that the transformation in the industrial structure of Xinjiang province is relatively slow.
Policies are implemented to accelerate their development. Xinjiang was proposed to be the “Core Area” of the Silk Road, and its geographical conditions were suitable for establishing it as a transportation hub and an open window. Shanxi is listed as a free trade zone, considering its geographical advantages and its economic foundation for playing a central role. Gansu, Ningxia, Qinghai, and other provinces have become important industrial and cultural exchanges bases through their cluster development. Guangxi has expanded its competitive advantage by its location near the sea, and by the Pearl River Delta. Due to different locational advantages, the dividends of BRI are not uniform over the different regions, and hence, there are differences in the development paths of the provinces.
6. Conclusions
This paper selected data from the 1990s to the present, finding that although there is an increasing labor force in western China, the region continues to have a low proportion of skilled workers. Since the implementation of BRI, the support for trade under this initiative is expected to bring about changes in this area. Our main interest lies in whether this change in trade will affect the number and structure of the local labor force. Using quantitative methods like VAR, SSA, and DIS, we arrived at the following conclusions:
By constructing a cointegration equation, we conclude that import and export trade volumes have a strong driving effect on the increase in the quantity of labor; in addition, the pull effect of the exports is greater. The impulse response function predicts that in the next 10 periods, the cumulative response of the total import and export volume will bring about a significant and continuous increase in employment in the western region of China. This is because the BRI has opened the channel to foreign markets, leading to an increase in labor demand, rising salaries, and labor force inflows. In addition, sufficient raw material inflow from neighboring countries will improve the competitiveness of the local industries, and thereby will attract more labor inflow.
Apart from the numerical changes, BRI leads to a structural change in the labor force. SSA results have seen the western area rapidly increase in the manufacturing industry, and its comparative advantage at national level. It implies an industrial upgrade in the area. While accepting the manufacturing industries that have shifted from the eastern regions, the western regions have also transferred low-end manufacturing to countries along the Road. Comparing the periods before and after 2015, the structural change accelerated after the implementation of BRI. With regard to DIS, the high deviation degree of manufacturing suggests a huge demand for labor, which will attract an increasing labor inflow.
As a key area of BRI, trade has gained support from many governments, and economic cooperation has been continuously strengthened. Among them, labor is an important indicator of regional economy, and its observation is of great significance for a dynamic evaluation in the future. Theoretically, this article pointed out BRI’s influence on labor mobility under the perspective of trade, and provided a workable quantitative method to analyze its influence on labor. Practically, the adjustment of the industrial structure has generated more jobs in the local areas. Using the results above, as more comparative advantages emerge with great policy bias toward western China, domestic and foreign firms find it more profitable to move in with lower cost and to open up the foreign market. This will provide more jobs in the western area. Labor would gradually move in or move back to search for higher welfare and for option value. With more incoming population flow, and a higher productivity, these developments will in turn increase the openness, and connect closer with countries along the Road.
However, such changes are yet to attract more labor. One explanation for this could be the “rigidity” in the labor market caused by the relatively underdeveloped economic conditions and social environment in the western regions; another is that there are large mobility costs when labor shifts occurs between sectors [
40].Therefore, the implementation of the BRI has required the government to cast increasing attention towards the development of the western regions, in terms of the welfare system, salary system, and other supporting infrastructure, to create a sound “soft” environment. For firms, it would be profitable to grasp policy advantages, invest on industries with high expansion space, and provide workers with necessary training to narrow the gap between the demand and labor quality. Furthermore, since the optimization and upgrade of industrial structure have accelerated the transfer of labor to high-efficiency sectors, the consistency between labor training and industrial change has become an urgent issue owing to China’s dual labor market. Another issue is that rapid acceleration in labor demand for skills and openness will widen the gap between skilled and low skill workers (Toh, 2012). To ensure that labor can adapt to this structural change, education and further training in professional skills should be considered seriously. By doing these the quality of labor will finally match up with companies’ demands, guaranteeing the sound functioning of society.
This article provides a feasible method for the prediction of foreign trade development and labor flow, gives a general example for the changing of variables under the impact of exogenous variables, such as policy shocks. It can also be applied into other regions inside China, and countries other than China, in not only BRI, but in other shocks. In the future, with the further implementation of the BRI initiative, more countries like Italy are recently becoming involved, the influence of the BRI would become stronger, providing clearer clues about the dynamic change of industries, as well as the labor market. However, there are still some limitations, and more efforts are needed. First, this article has categorized industries roughly as agriculture, manufacturing, and services, without specifically characterizing which firms might undergo significant changes, due to the policy shock. It only presents a vague map, and a more specific division is worth studying. Also, being limited by the available data, this paper may do better by using data at a finer level to improve the analysis. Furthermore, the analysis used indirect signals of labor inflows and outflows, by showing the development potentials and the relative labor demand. More straightforward quantitative methods may be applied in the future, based on data accessibility.
We may look forward to a greater upgrading of the industrial structure, accompanied by a more suitable labor structure. With the BRI, China has started to act within the frame of the UN 2030 Sustainable Development Goals. By expanding trade and technological exchanges, environmentally friendly sectors will expand under the basis of transferring excess capacity, which promotes economic growth and creates new jobs. This would help western China to improve its labor structure, maintaining labor balance across regions, and help countries along the BRI to actively increase employment and eliminate poverty. In the future, when the BRI plays an increasingly important role, the dynamic changes of industries, as well as the labor market, will become clearer. With more data accumulating, the limitations mentioned above can be overcome, as the mechanisms underlying this dynamic change become apparent, and organizations can leverage this mechanism. Also, other social parameters; for example, the population and quality of life in these territories, is also worth working on.
