2. The role of the supporting industry
2.1. Platforms for promoting industrial production
The supporting industry is likened to a "support" for the development of industrial production. By supplying raw materials, machinery, components and spare parts, this industry helps ensure a stable production process, improve the quality of output products and enhance production efficiency.
2.2. Promote specialization in production
The supporting industry creates conditions for businesses to focus on their core expertise, such as manufacturing, assembling the final product. Linking with suppliers of raw materials and components helps businesses optimize their supply chains, reduce costs and improve production efficiency, and ensure that products meet higher quality standards.
2.3. Paving the way for integration into the global supply chain
In the global manufacturing system, supporting industries play an important role in linking businesses into international supply chains. Multinational corporations often rely on supporting industries to develop their production and trade chains. This presents a great opportunity for businesses in developing countries, helping them to participate more deeply in the global market through the provision of components, raw materials and other supporting solutions.
2.4. Attracting foreign investment capital
In the context of globalization, large economic corporations and international investors are increasingly prioritizing countries with industrial systems to support development. Easy access to high-quality components, spare parts and materials is an important factor to help reduce operating costs and improve production efficiency. This attracts many foreign investors to build factories and production facilities in areas with strong supporting industries.
In addition, businesses in the domestic supporting industry can take advantage of this investment to innovate production processes, improve designs and quickly adapt to the strict requirements of the international market without spending initial research costs.

2.5. Promoting enterprises to apply high technology
The supporting industry encourages enterprises to innovate and apply modern scientific and technological solutions in production. Thanks to the peculiarity of quickly adapting to market trends, this industry creates a motivation for workers to access advanced technical advances, improve skills and improve labor productivity. At the same time, businesses also have the opportunity to apply high technology to optimize processes, reduce costs and increase product quality.
2.6. Contributing to promoting the country's industrialization and modernization
The supporting industry is an important driving force in the industrialization and modernization strategy of developing countries such as Vietnam. The development of this industry not only creates more jobs for cheap labor but also improves the added value of the economy. Moreover, a strong supporting industry system will help Vietnam reduce its dependence on component imports, thereby saving costs and increasing production autonomy.
3. The current situation of the supporting industry in Vietnam
3.1. Overview of the supporting industry market in Vietnam
In Vietnam, many industries such as automobiles, motorcycles, electronics and textiles are still mainly dependent on raw materials and components imported from abroad. According to the General Statistics Office, in the first 2 months of 2022, the import turnover of raw materials, components and machinery spare parts accounted for 93.5% of the total import value.
This dependence leads to many challenges for Vietnamese businesses. For example, in the automotive industry, to complete a product, about 20,000–30,000 components are needed, but the domestic automotive support industry can only meet 287 components and component assemblies. Similarly, the mechanical engineering industry also faces great difficulties due to the lack of spare parts and modern equipment, making the final product not accurate and of high quality, leading to high production costs but low commercial value, making it difficult to compete with foreign enterprises.
However, besides the limitations, Vietnam has emerged a number of pioneering enterprises in the supporting industry. Companies such as Thaco, Hyundai Thanh Cong and VinFast have actively invested in supporting industry systems, developing modern production lines and advanced equipment. These steps not only reduce dependence on imports but also help the domestic supporting industry gradually affirm its position, opening up the prospect of integration and competition in the international market.
3.2. Opportunities for the development of supporting industries in Vietnam
The Vietnamese government has constantly implemented policies to promote the development of the supporting industry, with a particular focus on the production of input materials and improving competitiveness. Industrial development support centers continuously research and test products such as components and machinery parts, in order to meet domestic demand and expand export markets.
In addition, many decrees and preferential policies have been issued, supporting manufacturing enterprises in fields such as automotive components, electricity, electronics, textiles and footwear. This not only helps businesses reduce costs but also facilitates their participation in the global supply chain.
The synchronization of solutions and policies from the government has brought great opportunities for Vietnam to improve its raw material production capacity, reduce dependence on imports and promote the stable development of the supporting industry. Many domestic component manufacturing enterprises have succeeded in meeting domestic demand, thereby creating a strong motivation for the supporting industry to develop sustainably and reach out to the international market.
